Crockpot Tuscan Garlic Chicken (Creamy Sun-Dried Tomato Sauce)

I made this crockpot Tuscan garlic chicken on a Tuesday when I had exactly zero energy to cook and a package of chicken breasts staring at me from the fridge. I threw everything into the slow cooker by 11am, and by dinner my kitchen smelled like a restaurant. My husband walked in and immediately asked what we were having — which almost never happens on a weeknight.

What makes this recipe work is the combination of garlic, sun-dried tomatoes, and heavy cream cooked low and slow — the sauce gets this deep, almost caramelized richness that you just can't fake on a stovetop in twenty minutes. I do sear the chicken before it goes in, which takes about five extra minutes, but that step makes a real difference in the final flavor. If you're in a rush, you can skip it, but I've made it both ways and the seared version is noticeably better.

My husband asks for this at least twice a month now. He eats it over pasta, Saad wants it with rice, and I usually just pile mine onto whatever crusty bread I have sitting around. It's one of those dinners where nobody at the table is complaining — which, honestly, is all I'm ever aiming for. If you like creamy slow-cooker dinners, my white lasagna soup has a similar vibe and is equally hands-off.

One thing to know before you start: the sauce will look a little thin when you first open the crockpot lid. Don't panic. Give it a stir, let it sit for a few minutes off the heat, and it thickens up. If it still feels too loose for you, the cornstarch slurry in the tips below fixes it in two minutes.

Why You'll Love This Recipe

• The slow cooker does the heavy lifting: I put this together before lunch and it's ready by dinner with zero babysitting required. There's no stirring, no checking, no hovering over the stove. On days when I have things going on from morning to afternoon, this is the kind of recipe that saves me from defaulting to takeout.

• The sauce tastes like you worked much harder than you did: Sun-dried tomatoes and garlic cooking in cream for four-plus hours creates something that's genuinely complex in flavor. I've had people ask me for the recipe thinking I spent all day on it, and I have to tell them the crockpot did most of it.

• Flexible enough to serve however your family eats: My husband wants pasta, my kids want rice, and I've served it over mashed potatoes when I didn't feel like boiling a pot. The sauce works with all of them. Even just a thick slice of bread works as a vehicle — something to soak up every bit of that cream sauce.

• Leftovers are genuinely good the next day: I always make a full batch because the leftovers heat up beautifully. The sauce thickens overnight in the fridge and the chicken shreds easily if you want to use it in a different way — like stuffed into a sandwich or tossed with pasta for lunch. I make a double batch when I know it's going to be a busy week.

• Accessible ingredients, nothing obscure: Everything on this list comes from a regular grocery store — Walmart, Kroger, Aldi, wherever you shop. Sun-dried tomatoes are in the pasta aisle (usually in a jar with oil, sometimes in a bag). No specialty store run required.

Ingredients

• 1.5 lbs (680g) boneless, skinless chicken breasts
• 1 tablespoon olive oil
• 3 cloves garlic, minced
• 1 cup heavy cream (half-and-half works in a pinch, sauce will be a bit thinner)
• ½ cup chicken broth
• ½ cup grated Parmesan cheese (freshly grated melts better than the pre-shredded kind)
• ½ cup sun-dried tomatoes, chopped (drained if packed in oil)
• 1 teaspoon Italian seasoning
• 1 teaspoon paprika
• Salt and black pepper, to taste
• 2 cups fresh spinach
• Optional: chopped fresh parsley for garnish

Directions

1. Season the chicken: Pat the chicken breasts dry with a paper towel, then season both sides with salt, pepper, paprika, and Italian seasoning. Drying the chicken first helps it sear properly — wet chicken just steams in the pan.
2. Sear the chicken (optional but worth it): Heat olive oil in a skillet over medium-high heat. Sear the chicken for 2–3 minutes per side until golden brown — you're not cooking it through, just building color. Transfer to your crockpot. This step adds a deeper flavor that the slow cooker alone doesn't quite get you.
3. Build the sauce: In a bowl, whisk together the minced garlic, heavy cream, chicken broth, Parmesan, and sun-dried tomatoes. Pour the whole thing over the chicken in the crockpot. No need to be precise about layering — it all comes together as it cooks.
4. Cook low and slow: Cover and cook on low for 4 hours or on high for 2–3 hours, until the chicken is cooked through and tender. I prefer low and slow when I have the time — the chicken stays juicier that way.
5. Add the spinach: About 10 minutes before serving, stir in the fresh spinach and let it wilt with the lid on. Don't add it earlier or it'll turn to mush. A quick stir is enough to get it incorporated into the sauce.
6. Serve: Spoon the chicken and sauce over pasta, rice, or mashed potatoes. Garnish with fresh parsley if you have it. Serve immediately while the sauce is still loose and creamy.

Tips for Success

• Don't skip the sear if you can help it: The first time I made this I went straight from raw chicken to the crockpot and skipped the searing step because I was in a hurry. The dish was fine, but it looked pale and tasted noticeably flatter. That five-minute sear adds a golden crust and a layer of flavor that the slow cooker can't replicate on its own.

• Use fresh garlic, not the jarred stuff: I know jarred minced garlic is convenient, and I do keep it in my fridge for emergency situations. But for this recipe specifically, fresh garlic makes a clear difference — it's sharper going in and mellower coming out after hours in the slow cooker. Three fresh cloves is all you need.

• Check the chicken at the minimum cook time: Crockpots vary a lot in how hot they actually run. I've overcooked chicken in mine before when I assumed I had another hour to spare. Check for doneness at the 3.5-hour mark on low — if a fork slides in easily and the juices run clear, it's done. Overcooked chicken in a crockpot turns stringy and dry even in a creamy sauce.

• Thicken the sauce if you want it richer: If the sauce is thinner than you'd like when you open the lid, mix 1 tablespoon of cornstarch with 2 tablespoons of cold water in a small bowl, then stir it into the crockpot. Turn the heat to high for about 15 minutes with the lid off. It firms up quickly and gives you that thick, coating sauce.

• Let the Parmesan come to room temperature before it goes in: I learned the hard way that cold Parmesan can clump in the cream instead of melting smoothly. Take it out of the fridge when you start prepping everything else. If you're using freshly grated (which I recommend), it melts into the sauce much more evenly than pre-shredded.

Variations

• Chicken thighs instead of breasts: Boneless skinless chicken thighs are more forgiving in the slow cooker — they have more fat running through them so they stay moist even if you cook them a little longer. My husband actually prefers the thigh version. The cook time stays the same, but check at 3.5 hours on low.

• Add mushrooms: Sauté sliced mushrooms with the garlic before adding them to the crockpot. They add an earthy, meaty texture that works really well with the creamy tomato sauce. I use cremini mushrooms — they hold their shape better than white button mushrooms during the long cook.

• Add a little heat: A pinch of red pepper flakes stirred into the sauce before cooking gives this a gentle warmth that cuts through the richness. My husband always adds more at the table. It's not spicy in an overwhelming way — more of a background heat that keeps the sauce interesting.

• White wine twist: Replace half the chicken broth with a dry white wine — something you'd actually drink, like a Pinot Grigio or Sauvignon Blanc. The wine adds acidity that balances the cream and makes the sauce taste more complex. This isn't authentic Italian at all, just my version, but it's a good one.

• Add artichoke hearts: Drain a can of artichoke hearts and add them along with the spinach in the last 10 minutes. They add a slightly briny, tender bite that works really nicely in this sauce. I'd seen this done with a similar dish and tried it on a whim — it's now my favorite variation to serve when we have people over.

Serving and Storage

Serving

Serve this hot, straight from the crockpot, over pasta (penne or fettuccine both work well), steamed rice, or mashed potatoes. Crusty bread on the side is non-negotiable in my house — you want something to mop up the extra sauce in your bowl. A little fresh parsley or extra Parmesan on top makes it look like you really tried. If you want a lighter side, a simple green salad cuts through the richness of the cream sauce nicely.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. The sauce will thicken considerably as it chills — that's normal. Reheat gently on the stovetop over low heat, adding a splash of chicken broth or cream to loosen it back up. You can also microwave it in 90-second intervals, stirring in between. I wouldn't freeze this one — cream-based sauces tend to split when thawed, and the spinach goes watery.

Frequently Asked Questions

Can I use frozen chicken?

I'd thaw it first. Cooking frozen chicken in a slow cooker is one of those things where food safety gets tricky — the meat spends too long in the temperature danger zone before it heats through. Thaw in the fridge overnight and you'll also get more even cooking throughout. If you forgot to thaw, a cold water bath for an hour does the job.

Can I make this dairy-free?

Yes — use full-fat coconut milk in place of the heavy cream and nutritional yeast instead of Parmesan. The flavor will be different (slightly coconut-forward), but it still works. I've done a similar swap in my coconut fish curry and the richness coconut milk adds to a cream-based sauce is genuinely nice.

What can I substitute for sun-dried tomatoes?

Roasted red peppers are the closest swap in terms of texture — chop them roughly and add the same amount. Cherry tomatoes (halved) also work but release more water, so your sauce will be thinner. The flavor won't be quite as concentrated and jammy as sun-dried tomatoes, but it's still a good dish. Sun-dried tomatoes are usually in the pasta/Italian aisle at most grocery stores, so they're worth hunting down.

Can I overcook the chicken in the crockpot?

Yes, absolutely. Chicken breasts especially go dry and stringy if they sit too long, even in liquid. Check at the 3.5-hour mark on low and again at 4 hours. If you need to hold it for longer, switch to the "warm" setting once it's done — don't keep it on low or high. Chicken thighs are more forgiving if you're worried about timing.

Can I assemble this the night before?

Yes — this is one of the things I love about slow cooker recipes. Put everything except the spinach in the crockpot insert, cover it, and refrigerate overnight. In the morning, pull it out of the fridge, let it sit on the counter for 10 minutes, then cook as directed. The spinach always goes in fresh at the end.

This Tuscan garlic chicken has become one of those recipes I come back to whenever I need dinner to basically make itself. The combination of sun-dried tomatoes, garlic, and cream in a slow cooker sounds simple because it is — but the result tastes like something you'd order at a sit-down restaurant and then spend the rest of the meal thinking about. I've made it probably a dozen times now and it's consistent every single time, which is saying something because I've had my share of crockpot disasters.

This is the kind of recipe I'd text a friend about on a Wednesday afternoon. Low effort, genuinely satisfying, and the leftovers are somehow even better the next day when the sauce has had overnight to settle. If you make it, I hope your family fights over the last spoonful the same way mine does. 🍝❤️
