19 BEST THANKSGIVING CASSEROLE RECIPES

Every Thanksgiving, I used to stress about the sides more than the turkey itself — the oven was always full, the timing never worked out, and I'd end up reheating something that deserved better. The year I leaned fully into Thanksgiving casserole recipes was the year everything changed. Casseroles go in the oven ahead of time, hold beautifully, and honestly generate more excitement at my table than almost anything else on the spread.

What I love about this collection is how much ground it covers — you'll find classic green bean casserole made from scratch without canned soup, multiple sweet potato variations from praline-topped to smoky and savory, corn pudding, cheesy cauliflower, stuffing loaded with apple and sausage, and even a keto-friendly option. There is genuinely something here for every dietary need and every flavor preference at the holiday table.

This list is for anyone hosting Thanksgiving and trying to get as much done ahead as possible — busy parents, first-time holiday hosts, and anyone who wants to spend less time in the kitchen on the day itself and more time with the people they love. Every single one of these casseroles can be assembled in advance and baked the day of, which is the whole point.

Save this post now because you will come back to it every November — and probably in between when you need a reliable, crowd-feeding side dish that requires almost no day-of effort. Let's get into all 19.

HEARTY AND DELICIOUS: BEST THANKSGIVING CASSEROLE RECIPES

19. Vidalia Onion Casserole

This casserole puts sweet Vidalia onions front and center — slow-cooked until caramelized and jammy, then baked with cheese and topped with crushed Ritz crackers for a golden, crunchy finish that contrasts beautifully with the soft onions underneath. It made this list because it's one of those underdog Thanksgiving sides that people eat and immediately ask what it is — nobody expects an onion casserole to be this deeply satisfying. I bring this to every November gathering now and it disappears before the sweet potatoes do. The key technique here is patience: don't rush the onion cooking step or you'll miss the sweetness that makes this dish what it is. Only 9 ingredients stand between you and the most talked-about side dish on your holiday table.

Ingredients:

• 3 large Vidalia onions, thinly sliced
• 3 tablespoons unsalted butter
• 3 large eggs, beaten
• 1 cup sour cream
• 1 teaspoon salt
• ¼ teaspoon black pepper
• 1 cup shredded sharp cheddar cheese
• 1 sleeve Ritz crackers, crushed
• 2 tablespoons butter, melted (for topping)

Instructions:

1. Preheat oven to 350°F. Melt butter in a large skillet over medium-low heat. Add sliced onions and cook, stirring occasionally, for 25–30 minutes until deeply golden and caramelized. Don't rush this step — low and slow is what builds the flavor.
2. Remove from heat and let cool for 5 minutes. Stir in beaten eggs, sour cream, salt, pepper, and half the shredded cheddar until fully combined.
3. Pour the onion mixture into a greased 9x9 inch baking dish and spread evenly. Sprinkle remaining cheddar across the top.
4. Toss crushed Ritz crackers with melted butter and scatter evenly over the cheese layer.
5. Bake at 350°F for 25–30 minutes until the top is golden brown and the filling is set and bubbling at the edges. Rest 5 minutes before serving.

18. Microwave Sweet Potato Casserole (Healthy!)

This lighter take on sweet potato casserole skips the marshmallows and butter-heavy topping in favor of bright citrus flavors — fresh orange juice and zest cut through the natural sweetness of the sweet potatoes for something that tastes genuinely fresh and seasonal. It earned its spot on this list because it's gluten-free, uses only 7 ingredients, and comes together entirely in the microwave — which means the oven stays free for the turkey and everything else competing for that rack space. This is the casserole I recommend to anyone hosting their first Thanksgiving who feels overwhelmed by oven logistics. The tip here is to taste and adjust the citrus level at the end — some sweet potatoes are sweeter than others, so the orange balance needs a final check before serving.

Ingredients:

• 3 large sweet potatoes, peeled and cubed
• ¼ cup fresh orange juice
• 1 teaspoon orange zest
• 2 tablespoons honey
• ½ teaspoon cinnamon
• ¼ teaspoon nutmeg
• Pinch of salt

Instructions:

1. Place cubed sweet potatoes in a large microwave-safe dish. Add 2 tablespoons of water, cover tightly with plastic wrap, and microwave on high for 10–12 minutes until completely tender when pierced with a fork.
2. Drain any excess water. Mash the sweet potatoes until smooth using a potato masher or fork.
3. Stir in orange juice, orange zest, honey, cinnamon, nutmeg, and salt until fully combined. Taste and adjust sweetness or citrus as needed.
4. Transfer to a microwave-safe serving dish. Microwave uncovered for 2–3 minutes more until heated through and fragrant. Serve immediately or cover and keep warm.

17. Easy 15-Minute Air Fryer Green Bean Casserole

Green bean casserole in 15 minutes flat — this air fryer version delivers the creamy filling and crispy fried onion topping everyone expects from the classic, but in a fraction of the time and without tying up oven space on the most oven-intensive cooking day of the year. It made this list because it's genuinely one of the most practical Thanksgiving side dishes I've found — fast, familiar, and completely satisfying. My kids specifically ask for this version now because the onion topping comes out crispier in the air fryer than it ever does in the oven. The most important tip: don't overcrowd the air fryer basket or the onion topping steams instead of crisps — work in batches if needed. This is the Thanksgiving side dish that saves the day when you've run out of oven space entirely.

Ingredients:

• 1 lb fresh or frozen green beans, trimmed
• 1 can (10.5 oz) condensed cream of mushroom soup
• ½ cup milk
• 1 teaspoon soy sauce
• ¼ teaspoon black pepper
• 1 cup French fried onions, divided
• Cooking spray

Instructions:

1. Preheat air fryer to 350°F. In a large bowl, mix cream of mushroom soup, milk, soy sauce, and pepper until smooth. Add green beans and half the fried onions and stir to coat evenly.
2. Spray a 7-inch air fryer-safe baking dish with cooking spray. Pour in the green bean mixture and spread evenly.
3. Air fry at 350°F for 10 minutes until heated through and bubbling at the edges.
4. Scatter remaining fried onions evenly over the top. Air fry for an additional 3–4 minutes until onions are golden and crispy. Serve immediately.

16. Quick and Easy Air Fryer Corn Casserole

Fluffy, creamy corn casserole with a golden brown top — made in the air fryer so the oven stays free for everything else on your Thanksgiving menu. This version has the same custardy interior and slightly crisp top that makes corn casserole so beloved, just cooked in significantly less time than the traditional oven method. I added this to the list because it's one of those recipes that genuinely surprises people — nobody expects corn casserole to come out of an air fryer, and nobody can tell the difference from the classic. The tip here is to check for doneness by inserting a toothpick in the center — it should come out clean with no wet batter when the casserole is properly set. This is the side dish that keeps disappearing before I even get to sit down.

Ingredients:

• 1 can (15 oz) whole kernel corn, drained
• 1 can (15 oz) creamed corn
• 1 box (8.5 oz) Jiffy corn muffin mix
• ½ cup sour cream
• ¼ cup unsalted butter, melted
• 2 large eggs, beaten

Instructions:

1. Preheat air fryer to 320°F. In a large bowl, combine all ingredients and stir until fully mixed — the batter will look slightly lumpy which is normal.
2. Grease a 7-inch round air fryer-safe baking pan with cooking spray. Pour the batter into the pan and smooth the top.
3. Air fry at 320°F for 25–30 minutes until the top is golden brown and a toothpick inserted in the center comes out clean.
4. Allow to cool for 5–10 minutes before slicing — the casserole needs this time to set properly. Serve warm directly from the pan.

15. Apple Sausage Stuffing

Sage-scented bread cubes, savory pork sausage, and sweet-tart apple pieces baked together into a stuffing casserole that has both the familiar holiday warmth and a subtle sweetness that keeps everyone coming back for seconds. This made the list because it threads the needle between classic and interesting — it's recognizably stuffing, but the apple component makes it distinctly its own thing that generates genuine conversation at the table. I make this every year as an alternative to standard stuffing for guests who want something a little more special, and it converts skeptics every single time. The key tip is to use slightly stale bread or toast your bread cubes before assembling — fresh bread turns to mush during baking while dried bread absorbs the flavors and holds its structure beautifully. Pair this with your Thanksgiving turkey for a combination that feels genuinely complete.

Ingredients:

• 1 lb pork breakfast sausage, removed from casing
• 1 large onion, diced
• 3 stalks celery, diced
• 2 Granny Smith apples, peeled, cored, and diced
• 3 cloves garlic, minced
• 8 cups cubed bread, dried overnight or toasted
• 2 cups chicken broth
• 2 large eggs, beaten
• 2 tablespoons fresh sage, chopped
• 1 tablespoon fresh thyme leaves
• Salt and black pepper to taste
• 2 tablespoons butter for the dish

Instructions:

1. Preheat oven to 375°F. Cook sausage in a large skillet over medium heat, breaking it up as it cooks, for 8–10 minutes until browned. Remove sausage with a slotted spoon and set aside, leaving drippings in the pan.
2. Add onion and celery to the drippings and cook for 5–6 minutes until softened. Add apple and garlic and cook 3 more minutes. Remove from heat.
3. In a large bowl, combine dried bread cubes, cooked sausage, and the apple-vegetable mixture. Add sage, thyme, salt, and pepper. Stir to distribute everything evenly.
4. Whisk together chicken broth and beaten eggs. Pour over the bread mixture and toss gently until all the bread has absorbed the liquid — the mixture should be moist but not soggy.
5. Transfer to a buttered 9x13 baking dish. Cover tightly with foil and bake at 375°F for 30 minutes. Uncover and bake 15–20 more minutes until the top is golden and crispy. Serve hot.

14. Smoky and Savory Sweet Potato Casserole

This is the sweet potato casserole for everyone who doesn't have a sweet tooth — instead of marshmallows or brown sugar streusel, it goes the opposite direction with smoked paprika, chipotle, and savory spices that transform sweet potatoes into something that genuinely complements the turkey rather than competing with the dessert table. It made this list because it fills a real gap — there's always someone at Thanksgiving who finds the standard sweet potato casserole too sweet, and this version gives them something genuinely satisfying to put on their plate. It's also naturally dairy-free and vegan, which is a practical bonus for diverse holiday tables. The most important tip is to taste and season the mashed sweet potato base before it goes into the dish — the smoky spice level needs to feel slightly intense at this stage because it mellows as it bakes. This is the side dish that makes guests rethink everything they thought they knew about sweet potatoes.

Ingredients:

• 3 lbs sweet potatoes, peeled and cubed
• 3 tablespoons olive oil
• 2 teaspoons smoked paprika
• 1 teaspoon chipotle chili powder
• 1 teaspoon garlic powder
• ½ teaspoon onion powder
• ½ teaspoon cumin
• Salt and black pepper to taste
• ¼ cup pepitas (pumpkin seeds) for topping
• Fresh cilantro or flat-leaf parsley for garnish

Instructions:

1. Preheat oven to 400°F. Toss sweet potato cubes with olive oil, smoked paprika, chipotle powder, garlic powder, onion powder, cumin, salt, and pepper. Spread on a parchment-lined baking sheet.
2. Roast at 400°F for 30–35 minutes until tender and caramelized at the edges, turning once halfway through. The edges should look slightly golden and deeply colored.
3. Transfer roasted sweet potatoes to a large bowl and mash thoroughly. Taste and adjust seasoning — the mixture should taste boldly spiced at this stage.
4. Transfer to a greased 9x9 baking dish and smooth the surface. Scatter pepitas evenly across the top.
5. Bake at 375°F for 15–20 minutes until heated through and the pepitas are toasted and fragrant. Garnish with fresh cilantro or parsley and serve hot.

13. Potato Egg Casserole

Thinly sliced potatoes layered with eggs, cream, and cheese and baked until golden and bubbling — this casserole sits somewhere between a gratin and a frittata and is genuinely one of the most versatile dishes on this entire list because it works for Thanksgiving brunch, as a hearty side, or as a full meal on its own. It earned its spot here because it's the kind of reliable, crowd-feeding dish that people return to again and again once they discover it, and it disappears from the table faster than most of the more elaborate options. I've made this as a Thanksgiving morning breakfast for the family while the turkey goes in the oven, and it sets the tone for the whole day. The most important tip is to slice the potatoes paper-thin — a mandoline makes this effortless and ensures even cooking throughout. You can customize with bacon, roasted peppers, or fresh herbs depending on what you have on hand.

Ingredients:

• 1.5 lbs Yukon Gold potatoes, very thinly sliced
• 6 large eggs
• 1 cup heavy cream
• 1 cup shredded Gruyère or Swiss cheese
• 1 small onion, thinly sliced
• 2 cloves garlic, minced
• 1 tablespoon fresh thyme leaves
• Salt and black pepper to taste
• 1 tablespoon butter for the dish

Instructions:

1. Preheat oven to 375°F. Butter a 9x9 baking dish generously. Layer half the sliced potatoes in overlapping layers across the bottom. Season with salt, pepper, and half the thyme.
2. Scatter sliced onion and minced garlic evenly over the potato layer. Add the remaining potato slices on top and season again with salt and pepper.
3. Whisk together eggs and heavy cream until smooth. Pour the egg mixture evenly over the potato layers — it should seep down between the layers. Scatter cheese evenly across the top.
4. Cover tightly with foil and bake at 375°F for 35 minutes. Remove foil and bake 20–25 more minutes until the top is golden brown and a knife inserted in the center meets no resistance from the potato layers.
5. Rest for 10 minutes before slicing — the egg custard needs time to set for clean slices. Garnish with remaining fresh thyme and serve warm.

12. Baked Cheesy Cauliflower Casserole

Cauliflower florets blanketed in a rich, sharp cheddar béchamel sauce and baked until the top is bubbling and golden — this is cauliflower cheese in its full British Sunday roast glory, and it belongs on every Thanksgiving table. It made this list because it's one of the most naturally gluten-adaptable sides you can make — swap the flour for a gluten-free alternative and the whole dish is accessible to guests with dietary restrictions without sacrificing any of the flavor. My family requests this more than any other vegetable side I make, and it converts people who claim not to like cauliflower almost every time. The tip that makes the biggest difference is to parboil the cauliflower only until just tender before it goes into the sauce — overcooked cauliflower turns to mush during baking and loses the textural contrast that makes this dish satisfying. Rich, cheesy, and completely reliable for a holiday spread.

Ingredients:

• 1 large head cauliflower, cut into florets
• 3 tablespoons unsalted butter
• 3 tablespoons all-purpose flour
• 2 cups whole milk, warmed
• 1½ cups sharp cheddar cheese, shredded, divided
• 1 teaspoon Dijon mustard
• ½ teaspoon garlic powder
• Salt, black pepper, and a pinch of nutmeg
• 2 tablespoons breadcrumbs for topping (optional)

Instructions:

1. Preheat oven to 400°F. Bring a large pot of salted water to a boil. Add cauliflower florets and parboil for 4–5 minutes until just barely tender — they should still have a slight bite. Drain thoroughly and transfer to a greased 9x13 baking dish.
2. Melt butter in a saucepan over medium heat. Whisk in flour and cook for 1–2 minutes until the mixture smells nutty and turns pale golden. This step cooks out the raw flour taste.
3. Add warm milk gradually, whisking constantly to prevent lumps, and cook for 4–5 minutes until the sauce has thickened enough to coat the back of a spoon. Remove from heat.
4. Stir in 1 cup cheddar, Dijon mustard, garlic powder, salt, pepper, and nutmeg until the cheese is fully melted and smooth. Pour the sauce evenly over the cauliflower.
5. Top with remaining cheddar and breadcrumbs if using. Bake at 400°F for 20–25 minutes until the top is deep golden and bubbling around the edges. Serve hot.

11. Green Bean Casserole Without Mushroom Soup

Green bean casserole built entirely from scratch — no canned soup, no shortcuts — with a from-scratch cream sauce, crispy bacon woven throughout, and a generous topping of fried onions that delivers the crunch everyone expects from this Thanksgiving classic. This made the list because it's the version I reach for when I want to serve something that feels genuinely homemade rather than assembled from pantry cans, and the flavor difference is substantial enough to justify every extra minute of preparation. The bacon addition is inspired — it adds a smoky, salty layer that fills in the depth that canned soup was previously providing. The single most important tip: make sure the green beans are properly blanched and dried before they go into the sauce — excess moisture makes the filling watery and prevents the topping from staying crispy. This is the green bean casserole that makes the classic feel new again. It pairs beautifully with our other easy fall side dishes.

Ingredients:

• 1.5 lbs fresh green beans, trimmed and blanched
• 4 strips bacon, cooked crispy and crumbled
• 3 tablespoons unsalted butter
• 1 small onion, finely diced
• 3 cloves garlic, minced
• 3 tablespoons all-purpose flour
• 1.5 cups chicken or vegetable broth
• ½ cup heavy cream
• 1 teaspoon Worcestershire sauce
• Salt and black pepper
• 1.5 cups French fried onions, divided

Instructions:

1. Preheat oven to 375°F. Blanch green beans in boiling salted water for 3 minutes, then immediately transfer to an ice bath to stop cooking and preserve the bright green color. Drain and pat thoroughly dry.
2. Melt butter in a large skillet over medium heat. Add diced onion and cook 4–5 minutes until softened. Add garlic and cook 1 minute more. Whisk in flour and cook 2 minutes until golden.
3. Add broth gradually while whisking to prevent lumps. Stir in cream and Worcestershire sauce. Simmer for 4–5 minutes until the sauce has thickened noticeably. Season generously with salt and pepper.
4. Add blanched green beans and crumbled bacon to the sauce and stir to coat evenly. Transfer to a greased 9x13 baking dish. Top with half the fried onions.
5. Bake at 375°F for 20 minutes until bubbling. Add remaining fried onions across the top and bake 5–8 more minutes until the onion topping is deeply golden and crispy. Serve immediately.

10. Sweet Potato Casserole with Praline Topping

Silky mashed sweet potatoes enriched with butter, brown sugar, and vanilla underneath a shatteringly crunchy praline topping of brown sugar, pecans, and butter — this is the sweet potato casserole that makes people genuinely excited to eat their vegetables at Thanksgiving. It made this list because the praline topping changes everything — it's caramelized and nutty and adds a textural contrast that marshmallows simply can't match, and once people have it they rarely go back to the marshmallow version. This is the dish my extended family has requested every single Thanksgiving for the past four years running. The tip that makes the praline topping work every time is to use cold butter cut into small pieces when making it — cold butter creates a crumbly, uneven texture that bakes to a genuinely crunchy result, while softened butter produces a greasy, flat topping that doesn't crisp properly. Plan this as one of your best Thanksgiving dinner ideas of the season.

Ingredients:

• 3 lbs sweet potatoes, peeled, cooked, and mashed
• ⅓ cup unsalted butter, softened
• ½ cup brown sugar, packed
• 2 large eggs, beaten
• 1 teaspoon vanilla extract
• ½ cup whole milk
• ½ teaspoon salt
• Praline Topping:
• 1 cup pecans, roughly chopped
• ⅓ cup all-purpose flour
• ⅓ cup brown sugar, packed
• 3 tablespoons cold unsalted butter, cut into small cubes

Instructions:

1. Preheat oven to 350°F. In a large bowl, combine mashed sweet potatoes with softened butter, brown sugar, beaten eggs, vanilla, milk, and salt. Mix until completely smooth and uniform. Taste and adjust sweetness if needed.
2. Spread the sweet potato mixture evenly into a greased 9x13 baking dish.
3. Make the praline topping: combine pecans, flour, and brown sugar in a bowl. Add cold butter cubes and work in with your fingertips until the mixture forms coarse, irregular crumbles — don't overwork it or the butter will become too incorporated.
4. Scatter the praline topping evenly across the entire surface of the sweet potato mixture.
5. Bake at 350°F for 30–35 minutes until the topping is deeply golden and crunchy and the filling is set with no jiggle in the center. Rest 5 minutes before serving.

9. Sweet Potato Crunch Casserole

Creamy sweet potato filling with just the right level of natural sweetness topped with a brown sugar and pecan crumble that delivers crunch in every bite — this version sits close to the praline casserole but uses a crumble topping with a slightly different texture and ratio of nuts to sugar that creates a more rustic, less candy-like finish. It made this list because it's the version I'd recommend when you want something a little less sweet and a little more textured than the classic praline version — the crumble is thicker and more substantial. My kids specifically request this version and eat it like dessert, which is not a criticism. The tip here is to let the crumble mixture get truly crumbly by keeping everything cold — if the butter softens before you mix it, the topping clumps together into one solid layer rather than dispersing in the crunchy shards that make it special. A genuinely reliable Thanksgiving crowd-feeder.

Ingredients:

• 3 cups mashed sweet potatoes (from about 2.5 lbs sweet potatoes)
• ¼ cup unsalted butter, softened
• ¼ cup granulated sugar
• 2 large eggs, beaten
• ½ cup evaporated milk
• 1 teaspoon vanilla extract
• Crunch Topping:
• 1 cup pecans, roughly chopped
• ½ cup brown sugar, packed
• ⅓ cup all-purpose flour
• ¼ cup cold unsalted butter, cubed

Instructions:

1. Preheat oven to 350°F. Beat together mashed sweet potatoes, softened butter, sugar, eggs, evaporated milk, and vanilla until smooth and fully combined. Spread evenly into a greased 9x9 baking dish.
2. Make the crunch topping: combine pecans, brown sugar, and flour in a bowl. Add cold butter cubes and use your fingertips to work the butter in until the mixture holds together in irregular clumps — some pea-sized pieces of butter remaining is what creates the crunch.
3. Scatter the crunch topping generously and evenly across the top of the sweet potato layer.
4. Bake at 350°F for 30–35 minutes until the topping is golden and crunchy and the filling is heated through and set. Check at 25 minutes — if the topping is browning too fast, tent loosely with foil for the remainder.
5. Rest for 5–10 minutes before serving. The filling firms up slightly during this time and makes for neater servings.

8. Southern Corn Pudding Casserole (No Jiffy Mix)

Made entirely from scratch without a box mix — this Southern corn pudding casserole sits between corn pudding and corn casserole in texture, with a custardy, slightly sweet interior that is genuinely unlike anything a box mix produces. It made this list because from-scratch corn pudding has a depth of flavor and a silkier texture that the Jiffy Mix shortcut cannot replicate, and because it's the dish that makes guests ask for the recipe before they've even finished their first serving. I bring this to every potluck and holiday dinner and it's the dish people talk about on the way home. The key tip is to use a combination of both whole kernel corn and creamed corn — the whole kernels add texture while the creamed corn provides the pudding-like consistency that makes this dish what it is. Let it rest for at least 10 minutes after baking before serving so the custard fully sets.

Ingredients:

• 1 can (15 oz) whole kernel corn, drained
• 1 can (15 oz) creamed corn
• 3 large eggs, beaten
• 1 cup sour cream
• ½ cup unsalted butter, melted
• ¼ cup all-purpose flour
• 3 tablespoons granulated sugar
• 1 teaspoon baking powder
• ½ teaspoon salt
• ½ teaspoon black pepper

Instructions:

1. Preheat oven to 350°F. Grease a 9x13 baking dish generously with butter. In a large bowl, whisk together eggs, sour cream, and melted butter until smooth.
2. Add flour, sugar, baking powder, salt, and pepper to the wet mixture and whisk until no dry streaks remain.
3. Fold in both cans of corn until fully incorporated — the batter should look slightly thicker than pancake batter.
4. Pour into the prepared baking dish and smooth the top. Bake at 350°F for 45–55 minutes until the top is golden brown and a toothpick inserted in the center comes out clean with no wet batter clinging to it.
5. Rest for 10–15 minutes before serving — the pudding needs this time to firm up from its jiggly baked state into a properly set, sliceable consistency.

7. Sweet Potato and Pecan Streusel Casserole

Classic sweet potato casserole meets a buttery, cinnamon-laced pecan streusel topping that shatters into golden shards with each spoonful — this version combines the comfort of the traditional dish with a topping so good it genuinely replaces the need for marshmallows entirely. It made this list because the streusel brings both texture and a warm, spiced nutty flavor that marshmallows simply can't offer, and because it presents beautifully on the holiday table with its golden, irregular surface. My family made the switch from marshmallows to streusel two Thanksgivings ago and there's no going back — the streusel version holds up longer under the heat of the table without collapsing or getting sticky. The tip that makes the streusel truly extraordinary is adding a generous pinch of flaky sea salt to the topping mixture before baking — the salt heightens every other flavor and creates the sweet-salty contrast that makes each bite genuinely hard to stop eating. This is the sweet potato casserole that earns its place at the top of the dish rotation.

Ingredients:

• 3 lbs sweet potatoes, peeled, cooked, and mashed
• ½ cup unsalted butter, softened
• ½ cup granulated sugar
• 2 large eggs, beaten
• ½ cup whole milk
• 1 teaspoon vanilla extract
• ½ teaspoon salt
• Pecan Streusel:
• 1 cup pecans, roughly chopped
• ½ cup all-purpose flour
• ½ cup brown sugar, packed
• ¼ cup cold unsalted butter, cubed
• ½ teaspoon cinnamon
• Pinch of flaky sea salt

Instructions:

1. Preheat oven to 350°F. Beat mashed sweet potatoes together with softened butter, sugar, eggs, milk, vanilla, and salt until completely smooth. Spread evenly into a greased 9x13 baking dish.
2. Make the pecan streusel: combine pecans, flour, brown sugar, and cinnamon in a bowl. Add cold butter cubes and pinch of flaky salt. Work in butter with fingertips until irregular crumbles form — some pea-sized butter pieces remaining is ideal.
3. Scatter streusel topping generously across the entire surface of the sweet potato base.
4. Bake at 350°F for 35–40 minutes until the streusel is deeply golden and the filling is set and not jiggling when the dish is gently shaken.
5. Rest 10 minutes before serving. The streusel will continue to crisp slightly as it cools, so resist serving immediately for the best texture.

6. Rigatoni al Forno

Rigatoni baked in a hearty meat sauce with mozzarella layered throughout and a golden, bubbly cheese crust on top — this is the Italian baked pasta casserole that belongs on a Thanksgiving table when you need to feed a crowd something deeply satisfying that isn't turkey-adjacent. It made this list specifically for families who want one non-traditional option in the mix — something for the kids, for the pasta lovers, and for anyone who needs a substantial, reliably eaten dish at a holiday table full of people with varying food preferences. I serve this as a first-course casserole or alongside the main spread when the guest list gets large enough that the turkey needs backup. The most critical tip is to undercook the pasta by 2 minutes before baking — al dente pasta going into a hot casserole will finish cooking in the oven, while fully cooked pasta becomes mushy and loses its structure entirely by the time the cheese is golden. A genuinely comforting addition to any holiday spread.

Ingredients:

• 1 lb rigatoni pasta, cooked 2 minutes under package directions
• 1 lb ground beef or Italian sausage
• 1 small onion, finely diced
• 3 cloves garlic, minced
• 1 jar (24 oz) marinara sauce
• 1 can (14 oz) diced tomatoes, drained
• 1 teaspoon Italian seasoning
• Salt, black pepper, and red pepper flakes
• 2 cups shredded mozzarella cheese, divided
• ½ cup freshly grated Parmesan cheese
• Fresh basil for serving

Instructions:

1. Preheat oven to 400°F. Brown ground beef or sausage in a large skillet over medium-high heat, breaking up as it cooks. Add onion and cook 4 minutes until softened. Add garlic and cook 1 minute more.
2. Add marinara sauce, diced tomatoes, Italian seasoning, salt, pepper, and red pepper flakes. Simmer for 10 minutes until the sauce is thick and deeply flavored.
3. Combine the slightly undercooked rigatoni with the meat sauce and toss to coat every piece of pasta evenly.
4. Spread half the pasta into a greased 9x13 baking dish. Scatter 1 cup mozzarella over this layer. Add the remaining pasta and top with remaining mozzarella and all the Parmesan.
5. Cover with foil and bake at 400°F for 20 minutes. Remove foil and bake 15–20 more minutes until the cheese is golden and bubbling with dark spots across the top. Rest 10 minutes before serving and finish with fresh basil.

5. Keto Chaffle Stuffing

All the savory, herb-scented satisfaction of traditional stuffing — celery, onion, sage, and broth — built on a base of chaffles (cheese-egg waffles) instead of bread for a completely low-carb version that doesn't taste like a compromise. It made this list because it solves a real Thanksgiving problem: what do you serve guests following a keto or low-carb diet who want to feel genuinely included in the spread rather than eating a pile of turkey with no sides? This is the answer, and it's genuinely good on its own terms — not just good "for keto." I've served this alongside traditional stuffing and had carb-eating guests choose this version out of curiosity and end up finishing it. The tip here is to let the chaffles sit out for a few hours before assembling so they dry slightly — moisture is the enemy of good stuffing texture regardless of whether it's bread or chaffle based. Pair this with your favorite Thanksgiving side dishes for a complete keto-friendly holiday spread.

Ingredients:

• 6 basic chaffles (1 egg + ¼ cup shredded mozzarella each), made ahead and dried
• 3 tablespoons unsalted butter
• 3 stalks celery, diced
• 1 medium onion, diced
• 3 cloves garlic, minced
• 1½ cups chicken broth
• 2 large eggs, beaten
• 2 tablespoons fresh sage, chopped
• 1 tablespoon fresh thyme leaves
• ½ teaspoon poultry seasoning
• Salt and black pepper to taste

Instructions:

1. Make chaffles ahead and allow to sit uncovered at room temperature for 2–4 hours until dry and slightly firm. Cut into 1-inch cubes.
2. Preheat oven to 350°F. Melt butter in a skillet over medium heat. Cook celery and onion for 6–7 minutes until softened. Add garlic, sage, thyme, and poultry seasoning and cook 2 more minutes until fragrant.
3. In a large bowl, combine chaffle cubes and the cooked vegetable mixture. Toss gently to distribute evenly.
4. Whisk together chicken broth and beaten eggs. Pour over the chaffle mixture and stir until all the cubes are moistened but not soaked — the mixture should hold together when pressed but not be wet.
5. Transfer to a greased 9x9 baking dish. Bake at 350°F for 30–35 minutes until the top is golden and the stuffing feels set and firm when lightly pressed. The edges should look golden and slightly crispy.

4. Sweet Potato Casserole with Pecan Streusel

Sweet potato casserole done in the way that makes you forget marshmallows ever existed — a deeply flavored sweet potato base topped with a sweet, salty, and wildly crunchy pecan streusel that delivers genuine texture and depth in every spoonful. This version made the list because the streusel achieves something marshmallows never could: it adds crunch, nuttiness, and a caramelized complexity that turns the entire dish into a genuinely multi-layered experience rather than a sweet and soft monotone. I'd serve this to sweet potato skeptics specifically — the contrasting textures and the salty-sweet streusel tend to change minds. The one tip that makes the biggest difference here is pressing the streusel topping gently into the sweet potato base before baking — this creates a slight bond between the layers that keeps the topping from sliding or shifting when the dish is served. A Thanksgiving table essential that earns its spot every single year.

Ingredients:

• 3 cups mashed sweet potatoes
• ⅓ cup unsalted butter, melted
• ⅓ cup granulated sugar
• 2 large eggs, beaten
• ½ cup evaporated milk
• 1 teaspoon vanilla extract
• Pecan Streusel:
• 1 cup pecans, chopped
• ⅓ cup all-purpose flour
• ⅓ cup brown sugar
• 3 tablespoons cold butter, cubed
• ½ teaspoon cinnamon
• ¼ teaspoon flaky sea salt

Instructions:

1. Preheat oven to 350°F. Combine mashed sweet potatoes with melted butter, sugar, eggs, evaporated milk, and vanilla. Mix until completely smooth and transfer to a greased 9x9 baking dish.
2. Make the pecan streusel by combining pecans, flour, brown sugar, cinnamon, and flaky salt. Add cold butter and work in with fingertips until coarse, crumbly clumps form.
3. Scatter streusel over the sweet potato base and press down very gently with your palm to help it adhere slightly.
4. Bake at 350°F for 30–35 minutes until the streusel is deeply golden and the sweet potato filling is set with no jiggle remaining in the center.
5. Rest for at least 8–10 minutes before serving. The streusel firms up further as it cools and the slices will hold their shape significantly better after this rest period.

3. Green Bean Casserole in the Slow Cooker

Classic green bean casserole made in the slow cooker — everything goes in the morning and by dinner time you have a bubbling, creamy, deeply flavored side dish waiting for you without a single oven rack being used. This is the most practical version on the entire list for Thanksgiving specifically, when oven space is the single most contested resource in the kitchen. It earned its spot because slow cooker green bean casserole isn't a compromise — the gentle, slow heat gives the beans time to fully absorb the sauce and develop a depth of flavor that the quick oven version can't match. This is one of the first things I set up on Thanksgiving morning so it requires zero attention while everything else is being managed. The critical tip is to add the fried onion topping only in the last 15 minutes of cooking — anything longer and they soften completely and lose the crunch that makes green bean casserole what it is. A genuinely hands-off holiday side that delivers every time. Look through our best ground beef casserole recipes for more casserole inspiration.

Ingredients:

• 2 lbs frozen green beans (do not thaw)
• 2 cans (10.5 oz each) condensed cream of mushroom soup
• ¾ cup whole milk
• 1 tablespoon soy sauce
• 1 teaspoon garlic powder
• ½ teaspoon black pepper
• 1½ cups French fried onions, divided

Instructions:

1. In a large bowl, whisk together cream of mushroom soup, milk, soy sauce, garlic powder, and black pepper until smooth and fully combined.
2. Add frozen green beans to the slow cooker insert. Pour the sauce mixture over the beans and stir to coat evenly. Add half the fried onions and stir them into the mixture.
3. Cook on LOW for 4–5 hours or HIGH for 2–2.5 hours, stirring once halfway through, until the beans are tender and the sauce is bubbling and thick.
4. In the last 15 minutes of cooking, scatter the remaining fried onions across the top. Do not stir — let them sit on the surface uncovered for the final 15 minutes so they retain as much crunch as possible.
5. Serve directly from the slow cooker. The casserole will hold on warm for up to 1 hour after cooking — ideal for Thanksgiving timing when dishes rarely all finish at exactly the same moment.

2. 5-Ingredient Corn Casserole

Five ingredients, one bowl, one baking dish — this Southern-style corn casserole is the most effortless recipe on this entire list and one of the most consistently eaten sides at every Thanksgiving table I've ever brought it to. It made this spot on the list because it's genuinely the dish that first-time Thanksgiving hosts should start with — there's almost nothing that can go wrong, and the result is a sweet, custardy, slightly cakey casserole that every person at the table will love regardless of age or food preference. I make a double batch every year because the first one disappears before the main courses are cleared. The one tip that makes this version stand out: don't overmix the batter — stir until just combined and stop, because overmixing makes the texture dense and bready rather than the light, slightly custard-like consistency that makes this casserole special. Serve alongside any of these other best BBQ side dishes for a complete spread.

Ingredients:

• 1 can (15 oz) whole kernel corn, drained
• 1 can (15 oz) creamed corn
• 1 box (8.5 oz) Jiffy corn muffin mix
• 1 cup sour cream
• ½ cup unsalted butter, melted

Instructions:

1. Preheat oven to 350°F. Grease a 9x9 or 9x13 baking dish generously with butter or cooking spray.
2. Combine all five ingredients in a large bowl — whole corn, creamed corn, Jiffy mix, sour cream, and melted butter. Stir until just combined. Do not overmix — stop as soon as no dry streaks of mix remain.
3. Pour into the prepared baking dish and spread into an even layer.
4. Bake at 350°F for 45–55 minutes until the top is golden brown and a toothpick inserted in the center comes out clean. The edges will pull slightly from the dish when done.
5. Rest for 10 minutes before serving — the texture improves significantly during this brief rest as the custard sets. Serve warm, scooped in generous spoonfuls directly from the dish.

1. Healthy Butternut Squash Casserole

Roasted butternut squash mashed and baked with warm spices, a touch of maple syrup, and a lightened topping that delivers all the satisfaction of a classic casserole with significantly less butter and sugar — this earns the top spot because it proves that healthy and genuinely satisfying are not mutually exclusive at the Thanksgiving table. It made the number one position because it's the recipe I've received the most requests for after serving it — people are surprised that something this flavorful is also genuinely nutritious, and it works equally well as a holiday side and as a regular weeknight dish throughout fall and winter. It's naturally gluten-free, easily made dairy-free, and can be assembled completely the day before and baked on the day. The most important tip is to roast the squash rather than boiling it — roasting concentrates the natural sugars and drives off excess moisture, giving you a casserole that holds its shape and tastes intensely of squash rather than tasting watered down. A Thanksgiving casserole you can genuinely feel good about putting on the table.

Ingredients:

• 1 large butternut squash (about 3 lbs), halved and roasted
• 2 tablespoons pure maple syrup
• 2 tablespoons coconut oil or unsalted butter, melted
• 2 large eggs, beaten
• ½ cup unsweetened almond milk or whole milk
• 1 teaspoon cinnamon
• ½ teaspoon nutmeg
• ¼ teaspoon ginger
• ½ teaspoon salt
• Topping:
• ½ cup old-fashioned oats
• ¼ cup pecans, roughly chopped
• 2 tablespoons maple syrup
• 1 tablespoon coconut oil, melted
• Pinch of cinnamon and salt

Instructions:

1. Preheat oven to 400°F. Place butternut squash halves cut-side-down on a parchment-lined baking sheet. Roast for 45–50 minutes until completely tender when pierced and caramelized at the edges. Scoop out flesh and mash thoroughly.
2. Reduce oven to 350°F. Combine mashed squash with maple syrup, coconut oil, eggs, milk, cinnamon, nutmeg, ginger, and salt. Mix until smooth. Transfer to a greased 9x9 baking dish.
3. Make the oat topping by combining oats, pecans, maple syrup, melted coconut oil, cinnamon, and salt. Stir to coat evenly.
4. Scatter the oat topping evenly over the squash layer.
5. Bake at 350°F for 30–35 minutes until the topping is golden and the casserole is set and fragrant. Rest 10 minutes before serving. The casserole can be made entirely the day before and reheated at 325°F for 20 minutes covered, then uncovered for 5 minutes to re-crisp the topping.

FAQs About Thanksgiving Casserole Recipes

What Thanksgiving casseroles can be made the day before?

Almost every casserole on this list can be fully assembled the day before, covered, and refrigerated overnight — just add 10–15 extra minutes to the baking time to account for the cold start. The sweet potato casseroles, butternut squash casserole, green bean casseroles, and corn pudding all hold extremely well assembled ahead of time. The one exception is any casserole with a crispy topping like fried onions — add those toppings just before baking to preserve their crunch. Making casseroles ahead is the single most effective strategy for a stress-free Thanksgiving day. Browse our full collection of best Thanksgiving dinner ideas for more make-ahead inspiration.

How do you keep Thanksgiving casseroles warm for serving?

Once baked, most casseroles hold at 200°F in the oven for up to 1 hour without significant quality loss — cover loosely with foil to prevent the top from over-browning while the rest of the meal finishes. Slow cookers set to warm are another excellent option for creamy casseroles like green bean casserole and corn pudding. For casseroles with crispy toppings like streusel or fried onions, avoid covering them or the topping will steam and soften — these are best served within 15 minutes of coming out of the oven for maximum crunch. Investing in a good insulated serving dish makes a meaningful difference for extended holiday table service.

Which Thanksgiving casserole is best for a large crowd?

The 5-ingredient corn casserole and the slow cooker green bean casserole are both extremely easy to scale up for large groups — simply double or triple the recipe and use larger baking dishes or multiple slow cookers. The sweet potato casseroles also scale beautifully and can be made in half-sheet pans when feeding 20 or more. For crowd cooking, always taste and re-season scaled-up recipes before baking since doubling doesn't always mean doubling the salt and spice levels perfectly. The apple sausage stuffing is another outstanding large-format option — it actually improves when made in larger batches because the flavors have more room to develop. For more large-format ideas, see our collection of best casserole recipes.

Can I freeze Thanksgiving casseroles?

Most baked casseroles freeze well for up to 3 months — the sweet potato casseroles, corn pudding, butternut squash casserole, and the stuffing all freeze and reheat beautifully. Green bean casserole is the notable exception: the green beans become mushy after freezing and the sauce can separate, making it best enjoyed fresh or within 3 days refrigerated. To freeze, let the casserole cool completely before wrapping tightly in plastic wrap and then foil. Thaw overnight in the refrigerator and reheat covered at 325°F until heated through. Add any crispy toppings fresh after reheating rather than freezing them with the casserole.

What's the most popular Thanksgiving casserole?

Green bean casserole is the most widely served Thanksgiving casserole in the United States by a significant margin — it's been a holiday table staple since Campbell's introduced the recipe in 1955, and it appears on an estimated 30 million Thanksgiving tables each year. Sweet potato casserole runs a close second, particularly in Southern households where it holds near-sacred status alongside the turkey. Corn pudding and stuffing casserole round out the top four most requested holiday casseroles nationally. If you're undecided about which recipe to start with this year, the green bean casserole without mushroom soup (recipe #11 on this list) is my personal starting recommendation — it takes the beloved classic and genuinely improves it.
