Rich tomato broth, tender broken lasagna noodles, and a creamy cheese topping give this high protein lasagna soup the same comfort as baked lasagna without the layering, waiting, or heavy finish. It eats like a full meal in a bowl, with lean turkey, white beans, and a tomato base that stays bright instead of turning muddy or overly thick.
What makes this version work is the order. The tomato paste gets cooked first so it loses that raw edge, and the broth simmers long enough to pick up flavor before the noodles go in. The cottage cheese topping is blended smooth, which keeps it from tasting grainy and lets it melt into the hot soup instead of sitting in curds on top.
Below, I’ll walk through the small details that keep the noodles from going soft and the topping from splitting. There’s also a few useful swaps if you want to change the protein or make it a little lighter on dairy.
The broth had real depth, the noodles stayed tender without falling apart, and blending the cottage cheese made the topping taste like ricotta. My husband went back for a second bowl before I even sat down.
Save this high protein lasagna soup for the nights when you want lasagna comfort with a lighter, bowl-of-soup finish.
The Tomato Broth Needs a Short Head Start Before the Noodles Go In
Lasagna soup can go wrong in a couple of familiar ways: the noodles overcook, the broth tastes flat, or the whole pot turns too thick before you’ve even ladled it out. The fix is to build flavor in the pot before the pasta ever touches the liquid. That means browning the turkey well, cooking the tomato paste until it darkens slightly, and letting the broth simmer with the tomatoes and seasonings before adding the noodles.
The other trap is crowding the pot with pasta too early. Broken lasagna noodles keep cooking after the heat is off, so you want them tender with a little bite, not soft enough to collapse. If the soup starts looking too dense before the noodles are done, add a splash more broth. The broth should stay spoonable, not turn into a casserole in disguise.
What Each Ingredient Is Doing in This Bowl
- Lean ground turkey or chicken — This gives the soup its protein and body without making the broth greasy. Turkey brings a little more savory depth; chicken stays lighter. Either one works, but don’t leave it in large chunks or you’ll miss the texture that makes this eat like lasagna instead of broth with pasta.
- White beans — These add creaminess and extra protein without changing the flavor much. Cannellini beans are the smoothest choice because they melt into the soup more gently. If you use another white bean, rinse it well so the broth stays clean-tasting.
- Tomato paste and crushed tomatoes — The paste gives the soup a concentrated, almost slow-cooked tomato base, while the crushed tomatoes keep it loose enough to feel like soup. Cooking the paste first matters. If you skip that step, the broth can taste sharp and raw.
- Lasagna noodles — Broken noodles give you the lasagna feel without the work of layering. Keep the pieces fairly large so they stay recognizable in the bowl. Smaller bits disappear faster and can make the soup feel less substantial.
- Cottage cheese, mozzarella, and parmesan — This topping is the reason the soup tastes like lasagna. Blending the cottage cheese smooth takes away the grainy texture and makes it closer to ricotta, while mozzarella adds melt and parmesan brings salt and depth. Part-skim mozzarella works fine here because it melts cleanly without making the topping oily.
Building the Soup So the Pasta Stays Tender and the Broth Stays Brothy
Brown the Meat First
Start with the turkey in a large pot over medium-high heat and break it up as it cooks. You want actual browning, not pale steaming, because those browned bits are what give the broth its savory backbone. If there’s excess fat in the pot after cooking, drain it before moving on, or the soup will taste heavy instead of rich.
Cook the Onion and Tomato Paste Until They Smell Sweet
Once the meat is out of the way, cook the onion in the same pot until it turns soft and translucent. Add the garlic for just a minute so it loses its raw bite, then stir in the tomato paste and let it cook briefly until it darkens and smells less sharp. That short toasting step is small, but it keeps the finished soup from tasting flat.
Simmer the Broth Before the Noodles Join In
Add the tomatoes, broth, Italian seasoning, oregano, and red pepper flakes, then bring the pot to a boil before lowering it to a steady simmer. This is where the soup develops its backbone, so don’t rush straight to the pasta. The beans go in with the noodles, and the whole pot should simmer just until the noodles are tender with a slight chew at the center.
Finish With the Cheese Topping at the Table
Blend the cottage cheese until smooth before mixing in the mozzarella and parmesan. Spoon it over hot soup right before serving so it softens into the broth without disappearing completely. If the soup is too hot and bubbling aggressively, the cheese topping can break apart instead of melting into a creamy layer, so let the bowl settle for a moment first.
Three Ways to Adjust the Soup Without Losing What Makes It Work
Dairy-Free Version
Skip the cheese topping and finish each bowl with a spoonful of dairy-free ricotta or a drizzle of olive oil and fresh basil. The soup itself already has enough body from the turkey, beans, and noodles, so you won’t lose the structure of the dish. What you give up is that lasagna-like creamy finish, but the broth still carries the same savory tomato flavor.
Gluten-Free Swap
Use certified gluten-free lasagna noodles and watch the simmer closely, because gluten-free pasta can go soft faster than standard noodles. The flavor stays the same, but the texture changes quickly once the pasta is tender. If you know you’ll have leftovers, cook the noodles separately and add them to each bowl so they don’t swell in the fridge.
Extra-Hearty Version
Add an extra half can of beans or a handful of chopped spinach near the end of cooking. The beans make the soup thicker and even more filling, while spinach wilts in without changing the base flavor. Don’t add too many extra ingredients or the broth stops tasting like lasagna soup and starts tasting crowded.
Storage and Reheating
- Refrigerator: Store in an airtight container for up to 4 days. The noodles will keep soaking up broth, so expect the soup to thicken.
- Freezer: The base freezes well, but the noodles soften after thawing. For the best texture, freeze the soup without pasta and cook fresh noodles when you reheat it.
- Reheating: Warm it gently on the stove over medium-low heat with a splash of broth or water. High heat can make the noodles mushy and can tighten the dairy topping if you add it too early.

- Heat a large Dutch oven over medium-high heat and brown the ground turkey, breaking it up. Continue until no longer pink, then drain excess fat.
- Sauté the diced onion in the same pot for 4 minutes, stirring until softened. Add the minced garlic and cook for 1 minute, just until fragrant.
- Stir in the tomato paste and cook for 1-2 minutes to deepen the flavor. Keep it moving so it doesn’t burn.
- Add crushed tomatoes, chicken broth, Italian seasoning, dried oregano, and red pepper flakes, then bring the mixture to a boil. Watch for active bubbling across the surface.
- Add the broken lasagna noodles and drained white beans to the pot. Return to a gentle boil if needed, then reduce to a simmer.
- Simmer for 10-12 minutes, until the noodles are tender and the broth thickens slightly. Stir occasionally to prevent sticking.
- Season with salt and black pepper to taste. Adjust at the end so the flavor stays balanced after simmering.
- Blend the cottage cheese until smooth. Aim for a creamy texture with no lumps.
- Mix the blended cottage cheese with part-skim mozzarella and parmesan. Stir until the topping is evenly combined.
- Ladle the hot soup into bowls. Top each bowl with the high-protein cheese mixture for a melted, creamy finish.
