Chicken lasagna soup hits the bowl with the same comfort as a bubbling pan of lasagna, but without the layering, waiting, or cleanup. The broth turns rich and tomato-forward, the broken noodles soak up all that flavor, and the cheese dollop melts into the center so every spoonful tastes creamy, tangy, and just a little indulgent. It’s the kind of dinner that looks like you spent all afternoon on it, even though it comes together in one pot.
What makes this version work is the way the base builds in stages. Browning the chicken first gives the soup a savory backbone, then the tomato paste cooks briefly with the onion and garlic so it loses that raw edge and turns deeper and sweeter. The noodles go in near the end, which keeps them from going mushy, and the ricotta-mozzarella topping gives you the lasagna finish without thickening the whole pot into paste.
Below, I’ve included the little details that matter most: how to keep the noodles from overcooking, how to adjust the broth so the soup stays spoonable, and a few smart variations if you want to stretch it or change it up.
The broth got deep and tomato-rich, and the lasagna noodles stayed tender instead of falling apart. The cheese dollop melted into the soup just like real lasagna filling, and my husband went back for a second bowl.
Save this Chicken Lasagna Soup for the nights when you want all the comfort of lasagna in one steaming bowl.
The Trick to Keeping This Soup From Turning Into Pasta Porridge
The biggest mistake with lasagna soup is letting the noodles sit in the pot too long. Broken lasagna sheets keep cooking after the heat is off, and if they hang around in broth for an hour, they’ll drink it up and go soft fast. This version avoids that by simmering the noodles only until they’re tender, then serving right away with the cheese dollop on top.
The second thing that matters is the tomato base. Tomato paste needs that minute or two in the pot before the liquids go in, because raw tomato paste tastes sharp and one-note. Cooked with onion and garlic, it turns rounder and gives the broth a deeper, almost slow-simmered taste without adding extra time.
What Each Ingredient Is Actually Doing in the Bowl
- Chicken thighs or breast — Thighs stay a little juicier, especially if the soup simmers a touch longer. Breast works fine if you keep an eye on it and pull the pot as soon as the chicken is cooked through.
- Tomato paste — This is the depth-builder. Let it cook with the onion and garlic so it darkens slightly and loses the raw taste before the broth goes in.
- Crushed tomatoes plus diced tomatoes — The crushed tomatoes make the broth thick and silky, while the diced tomatoes leave a little texture behind. Using both gives the soup that lasagna-sauce feel without needing cream.
- Lasagna noodles — Regular dried noodles are best here because they hold up and give you that real lasagna bite. Break them into rough pieces so they settle naturally in the spoon instead of sticking together in long strips.
- Ricotta, mozzarella, parmesan, and basil — This is the part that makes it taste like lasagna instead of just tomato chicken soup. Fresh basil cuts through the richness, and the parmesan sharpens the cheese topping so it doesn’t taste flat.
How to Build the Soup in Layers, Not All at Once
Browning the Chicken First
Start the chicken in a hot pot with a little olive oil and leave it alone long enough to pick up color. You’re not cooking it through here; you’re building flavor on the bottom of the pan. If the pot looks crowded, work in batches, because steamed chicken won’t give you the savory base this soup needs.
Softening the Onion and Toasting the Tomato Paste
Once the chicken comes out, the onion goes into the same pot to pick up every browned bit left behind. When it turns translucent and smells sweet, add the garlic and tomato paste and stir for a couple of minutes. That short cooking time matters because it deepens the paste and keeps the garlic from tasting harsh.
Simmering the Broth and Noodles
After the tomatoes, broth, and seasonings go in, bring the pot to a boil and then settle it down to a steady simmer. Add the chicken back with the broken noodles and cook just until the noodles are tender and the chicken is done. If the simmer is too hard, the noodles can break down and cloud the broth, so keep it gentle.
Finishing With the Cheese Dollop
Mix the ricotta, mozzarella, parmesan, and basil in a bowl while the soup finishes. Spoon a generous mound into each bowl right before serving so it softens into the broth without disappearing completely. The contrast between hot soup and cool cheese is part of what makes each bowl taste layered and complete.
How to Adapt This for Different Eaters and Leftovers
Use Gluten-Free Pasta Without Losing the Comfort
Swap in a sturdy gluten-free lasagna noodle or another short pasta with good structure. Cook it just until tender, because gluten-free pasta can go from al dente to bloated faster than wheat pasta, especially in hot broth.
Make It Dairy-Free Without the Cheesy Finish
Skip the ricotta-mozzarella topping and finish each bowl with a spoonful of dairy-free cashew cream or a drizzle of olive oil plus extra basil. You’ll lose the classic lasagna creaminess, but the broth itself still carries the dish.
Turn It Into a Thicker, Heartier Bowl
Use thighs, add an extra tablespoon of tomato paste, and let the soup simmer a few minutes longer before the noodles go in. That gives you a richer broth that clings a little more to the noodles and chicken, closer to a saucy lasagna filling.
Storage and Reheating
- Refrigerator: Store for up to 4 days. The noodles will keep absorbing broth, so expect the soup to thicken.
- Freezer: Freeze the soup without the noodles for the best texture. Cook fresh noodles when you reheat it, or the pasta will turn soft and swollen after thawing.
- Reheating: Warm gently on the stove over medium-low with a splash of broth or water. If the soup boils hard, the noodles can break apart and the chicken can dry out.

Method
- Cook the diced chicken in olive oil in a large pot over medium-high heat until browned, about 6-8 minutes; remove and set aside (look for golden-brown edges).
- Sauté the diced onion in the same pot for 4 minutes over medium-high heat until softened and lightly translucent (stir frequently so it cooks evenly).
- Add the minced garlic and tomato paste and cook for 2 minutes over medium-high heat until fragrant (paste should darken slightly).
- Add the crushed tomatoes, diced tomatoes, chicken broth, Italian seasoning, dried basil, dried oregano, and red pepper flakes; bring the mixture to a boil (you should see steady bubbling across the surface).
- Return the browned chicken to the pot and add the broken lasagna noodles (spread noodles out so they cook through).
- Simmer for 10-12 minutes until the noodles are tender and the chicken is cooked through (the soup should bubble gently and noodles should soften when pressed).
- Season with salt and pepper to taste (adjust until the broth tastes balanced and savory).
- Mix the cheese dollop by combining ricotta, shredded mozzarella, and parmesan with fresh basil (aim for a thick, scoopable mixture).
- Serve by adding a generous spoonful of the cheese dollop to each bowl (it should melt on contact with the hot soup).
