White Chicken Lasagna Soup (Creamy One-Pot Comfort Bowl)

I made this soup for the first time on a Tuesday in October when it was raining and I had leftover rotisserie chicken sitting in the fridge. I wasn't planning anything fancy — I just wanted something warm, something my kids would actually finish, and something that didn't require me to stand in the kitchen for an hour. What came out of that pot surprised me. It tasted like someone had taken a pan of white chicken lasagna and turned it into a hug.

The idea was simple: cook lasagna noodles directly in a creamy, cheesy broth with shredded chicken instead of building layers and baking a whole dish. What I didn't expect was how well it worked. The noodles soak up the flavor as they cook, the Parmesan and mozzarella melt right into the broth, and the whole thing comes together in one pot in under 35 minutes. I've made it at least six times since that Tuesday and barely changed a thing. If you like chicken Alfredo stuffed shells, this soup will feel very familiar — same cozy, cheesy energy, just in bowl form.

My husband ate two bowls the first night and asked me to write down what I put in it. Saad, who normally picks things apart, stirred his noodles around for a minute and then quietly finished everything. That's the highest endorsement I get from a seven-year-old. Zainab ate hers with extra Parmesan on top, which is her solution for everything. We now make this at least twice a month through the cooler months.

One thing I'll tell you upfront: the noodles do swell quite a bit as they sit, especially if you're making this ahead. If you're planning to store leftovers, either cook the noodles separately or add extra broth when you reheat. I learned this the hard way — made a big batch on Sunday thinking I'd have lunch ready for two days, and by Monday the whole thing had turned into a thick pasta casserole. Still tasted good, but required a full cup of extra broth to get it back to soup consistency.

Why You'll Love This Recipe

• One pot, real cleanup: Everything — the aromatics, the broth, the noodles, the cream, the cheese — all goes into a single large pot. I'm not washing a colander, a baking dish, AND a saucepan at 8pm on a weeknight. The pot goes on the stove, food comes out, done. Even my husband will do the dishes when it's just one pot.

• Ready in about 35 minutes: From the moment I dice the onion to the moment I ladle this into bowls, it's around 35 minutes. I use rotisserie chicken from Costco or Walmart which cuts out the biggest time commitment. On nights when everyone's tired and hungry, this is genuinely faster than ordering delivery.

• That broth is genuinely good: I've made plenty of cream-based soups that taste flat or too heavy. This one doesn't, because the Parmesan brings sharpness, the garlic and Italian seasoning add depth, and the chicken broth keeps it from feeling too rich. It's the kind of broth I end up spooning straight from the pot while I'm "tasting for seasoning."

• Works with what you have: No lasagna noodles? Break up any wide pasta — pappardelle, fettuccine, even regular spaghetti snapped into thirds. No heavy cream? Half-and-half works. No rotisserie chicken? Poach two chicken breasts in the broth before you start and shred them. This recipe is forgiving in a way that a baked lasagna simply is not.

• Leftovers are genuinely worth keeping: The flavor deepens overnight. I've had this cold, straight from the fridge the next morning, and it's still good. Just remember to add a splash of broth or milk when you reheat because the noodles keep absorbing liquid. Serve it with my homemade garlic butter cheese bombs and it becomes a full meal worth looking forward to.

Ingredients

• 2 tablespoons butter
• 1 tablespoon olive oil
• 1 medium yellow onion, diced
• 3 cloves garlic, minced
• 2 cups cooked chicken, shredded (rotisserie chicken works great)
• 4 cups low-sodium chicken broth
• 2 cups whole milk
• 1 cup heavy cream (or half-and-half in a pinch)
• 8 lasagna noodles, broken into roughly 2-inch pieces
• 1 teaspoon Italian seasoning
• ½ teaspoon salt (plus more to taste)
• ½ teaspoon black pepper
• 1 cup shredded mozzarella cheese
• ½ cup grated Parmesan cheese (plus extra for serving)
• 1 cup baby spinach, optional
• Fresh parsley, chopped, for garnish

Directions

1. Sauté the aromatics: In a large heavy pot, melt the butter with the olive oil over medium heat. Add the diced onion and cook for about 5 minutes, stirring occasionally, until it's soft and translucent. Add the minced garlic and cook for another 30 seconds, just until fragrant — don't let it burn or the whole soup will taste bitter.
2. Add the chicken and liquids: Stir in the shredded chicken, Italian seasoning, salt, and pepper. Pour in the chicken broth and milk. Stir everything together and bring it up to a gentle simmer over medium-high heat. Don't rush this to a full boil — a simmer is what you want.
3. Cook the noodles: Add the broken lasagna noodles to the simmering broth. Cook for 10–12 minutes, stirring every couple of minutes to keep the noodles from sticking to the bottom. Taste one at the 10-minute mark — they should be tender but still have a little bite.
4. Stir in the cream and cheese: Lower the heat to medium-low and pour in the heavy cream. Add the mozzarella and Parmesan and stir steadily until both cheeses melt completely into the soup. This takes 2–3 minutes. Don't let it boil after adding the cream or you risk it separating.
5. Add spinach and finish: If you're using spinach, stir it in now and let it wilt for 2 minutes. Taste the soup and adjust salt and pepper as needed. Ladle into bowls and top with fresh parsley and extra Parmesan.

Tips for Success

• Use rotisserie chicken: I started doing this after my third time making this soup, and it genuinely cuts the prep in half. A Costco rotisserie chicken gives you more than enough shredded meat and the flavor is already well-seasoned. Just pull it apart with two forks while the onions are cooking and you're ready to go.

• Lower the heat before adding dairy: This is the step I got wrong the first time I made it. I added the cream while the pot was still at a rolling boil and ended up with a grainy, slightly curdled broth. Once you add the cream and cheese, keep the heat at medium-low or lower. Slow and gentle melts cheese beautifully; high heat breaks it.

• Stir the noodles regularly: Lasagna noodles are wide and starchy and they will absolutely glue themselves to the bottom of your pot if you walk away. Set a timer for every 2 minutes and give the pot a stir. It sounds fussy but it takes three seconds and saves you from scraping burnt pasta off your pot later.

• Don't over-salt at the start: Both the chicken broth and the Parmesan bring saltiness to this soup, and it concentrates slightly as it cooks. I season lightly at the beginning and do my real tasting and adjusting right at the end, once the cheese is melted in. It's much easier to add salt than to fix an over-salted soup.

• If storing, separate the noodles: I know I already mentioned this in the intro, but it's worth repeating because I've made this mistake more than once. If you know you're making this for meal prep, cook the noodles in a separate pot and store them apart from the soup base. Combine only when serving. The soup base keeps in the fridge for 4 days; the noodles keep for 3.

Variations

• Add cream cheese for extra richness: Drop 3–4 ounces of softened cream cheese in with the mozzarella and Parmesan. It melts in slowly and makes the broth noticeably thicker and more velvety. My husband prefers this version. Just cut the cream cheese into small chunks first so it melts evenly rather than staying in one big blob.

• Make it vegetarian: Skip the chicken and swap chicken broth for vegetable broth. Add 1 cup of sliced cremini mushrooms with the onions at the start, and throw in a can of drained white beans with the noodles. It gives the soup substance and protein without the meat. I've served this version to guests who don't eat chicken and nobody felt like they were eating a lesser version of the dish.

• Turn up the heat: Add ½ teaspoon of crushed red pepper flakes with the garlic, and a dash of hot sauce at the end. This is how I make it for myself on nights when the kids are eating something else. The heat cuts through the richness of the cream in a really good way.

• Swap the cheese: Mozzarella is mild and melts smoothly, but if you want more flavor, try mixing in some Gruyère or sharp white cheddar. I've used a combination of mozzarella and Gruyère and it tasted more complex — almost like a French onion situation. Just make sure whatever cheese you use is shredded fresh from the block; pre-shredded bags have coatings that can make the soup grainy.

• Use turkey instead of chicken: This is my go-to the week after Thanksgiving when I always have leftover roasted turkey that needs to be used. The flavor is slightly richer than chicken, and it works just as well. Shred it the same way and use it in a 1:1 swap. It makes the soup feel different enough that my family doesn't notice we're eating holiday leftovers for the fourth day in a row.

Serving and Storage

Serving

Serve this soup hot, straight from the pot, with a generous shower of extra Parmesan on top. We almost always have it with crusty bread on the side — my family likes to use the bread to scoop up the noodles at the bottom of the bowl. If you want something more substantial, a simple green salad alongside balances the richness well. In Pakistan, we'd typically have a soup like this as a starter, but in my house this is dinner. One bowl is genuinely filling.

Storage

Store leftovers in an airtight container in the fridge for up to 3–4 days. The noodles will continue absorbing the broth as they sit, so when you reheat, add ½ cup of chicken broth or milk and stir over medium-low heat until it loosens back to soup consistency. To freeze: let the soup cool completely, then freeze the base WITHOUT the noodles for up to 2 months. When ready to eat, thaw overnight in the fridge, reheat gently, and cook fresh noodles directly in the reheated soup.

Frequently Asked Questions

Can I freeze white chicken lasagna soup?

Yes, but freeze the soup base without the noodles — dairy soups can get a slightly grainy texture after freezing, and noodles turn mushy. Let the base cool fully, freeze in airtight containers for up to 2 months, then thaw overnight in the fridge. Reheat gently on the stovetop and add freshly cooked noodles when you're ready to serve.

What can I substitute for heavy cream?

Half-and-half works well and makes the soup a little lighter without losing the creamy texture. You can also use whole milk with 2–3 ounces of softened cream cheese stirred in — it adds richness and body similar to heavy cream. I've used both substitutes and the soup still comes out very satisfying.

Can I make this in a slow cooker?

Yes. Sauté the onion and garlic on the stovetop first, then transfer to the slow cooker with the chicken, broth, milk, and seasoning. Cook on low for 4–5 hours or high for 2–3 hours. Add the broken noodles in the last 30–40 minutes, then stir in the cream and cheese right before serving. Don't add the dairy earlier or it can separate over long cooking times.

How do I keep the noodles from getting soggy in leftovers?

The best solution is to cook the noodles separately and store them apart from the soup base. When you're ready to eat, reheat the base and add the noodles to individual bowls as you serve. If you've already mixed everything together, just know the noodles will soften quite a bit — add extra broth when reheating and they'll still taste fine, just softer than freshly made.

Can I use uncooked chicken instead of pre-cooked?

Yes. Add 2 raw boneless chicken breasts directly to the broth in Step 2, bring to a simmer, and cook for about 15 minutes until cooked through. Remove the chicken, shred it with two forks, then return it to the pot before adding the noodles. It adds maybe 20 extra minutes but works perfectly if you don't have pre-cooked chicken on hand.

This soup has become one of those recipes I don't even look at anymore — I just make it from memory, adjusting as I go depending on what's in the fridge. Some nights I add mushrooms, some nights I throw in extra spinach, some nights it's just the base recipe and that's more than enough. The base is genuinely solid on its own, and everything else is optional.

If you're the kind of person who likes having dessert ready when a soup night is planned, I'd suggest making my no-bake mini banana cream pies ahead of time. They sit in the fridge while dinner cooks, and cold, creamy pie after a warm cheesy soup is a combination I've tested more than once and fully stand behind.

What I keep coming back to with this recipe is how low the effort feels relative to how satisfying it is. There's no layering, no baking, no special equipment. A large pot, a wooden spoon, and about 35 minutes. I'm not a trained chef, I don't have a professional kitchen, and I make this on school nights when I'm tired. If it works in my house, it'll work in yours. 🍲🧀✨
