On a chilly evening I wanted all the cozy familiarity of lasagna without the time and pans, so I developed this lasagna soup that delivers the same tomato-meat-cheese comfort in one pot. Lasagna soup brings the classic flavors together quickly; the broken lasagna noodles cook right in the broth, and a short off-heat rest keeps the noodles from going mushy. If you like dependable weeknight dinners with big lasagna flavor and minimum fuss, this recipe is for you.
Why this lasagna soup works
The trick behind a reliable lasagna soup is balancing noodle cooking and sauce concentration. I use a 1:4-ish ratio of pasta to liquid so the broth stays richly tomato-forward after the noodles finish, and I brown the meat and sauté the aromatics first to develop savory depth. During testing I found that adding the cheese mixture off the heat and letting the pot rest for 5–8 minutes kept the ricotta from separating and the noodles from overcooking. The final texture is a slightly thickened, spoonable tomato broth studded with tender-rather-than-mushy noodle ribbons and a creamy cheese ribbon on top.
Key takeaways
- Brown meat and sweat aromatics first to build flavor.
- Use broken lasagna noodles and a short off-heat rest to avoid soggy pasta.
- Finish with a stirred ricotta-parmesan mix off the heat for creamy texture.
Ingredients you’ll need and what to substitute
You’ll need ground beef or turkey, canned crushed tomatoes, chicken or beef broth, lasagna noodles that you break into pieces, ricotta, and shredded mozzarella. I prefer a 20-ounce can of crushed tomatoes for body plus a 14-ounce diced can if you like small tomato chunks. For a lighter weeknight version use ground turkey; for deeper flavor use a 90/10 ground beef. If you’re short on ricotta you can use 1/2 cup cream cheese mixed with 1/4 cup milk as a substitute—expect a slightly richer, tangier finish. Use low-sodium broth if you want control over salt; adjust salt at the end. Fresh basil is great, but dried oregano or a pinch of fennel seeds work in a pinch. If you only have regular spaghetti, it will work but break it into 2–3 inch pieces and reduce the liquid by about 1/2 cup.
Equipment
Essential kit: a 5– to 6‑quart heavy-bottomed Dutch oven or large soup pot (this recipe will splatter in smaller pans), a wooden spoon or heatproof spatula, a liquid measuring cup, and a box grater for the cheese. A colander is helpful if you prefer to drain the browned meat. If you have a splatter screen, use it when simmering to reduce oven cleaning later.
How to make lasagna soup
Brown the meat and aromatics
Heat 1 tablespoon of olive oil in the Dutch oven over medium-high heat until shimmering. Add 1 pound of ground beef (or turkey), breaking it into small pieces. Cook without crowding until the meat has nice brown bits, about 6–8 minutes. Drain off excess fat if there’s more than 1 tablespoon. Reduce heat to medium, add 1 medium diced onion and 2 minced garlic cloves, and sauté until translucent and fragrant, about 4 minutes—this step builds the base flavor.
Build the tomato broth
Stir in 2 tablespoons tomato paste and cook 1 minute to caramelize slightly. Pour in 6 cups low-sodium chicken broth and scrape up any browned bits from the bottom. Add a 20-ounce can crushed tomatoes and a 14-ounce can diced tomatoes with their juices, 1 teaspoon dried oregano, 1/2 teaspoon dried basil, 1/4 teaspoon red pepper flakes (optional), and 1 teaspoon kosher salt. Bring to a gentle simmer, then reduce heat to medium-low and simmer uncovered for 10 minutes to let the flavors marry and the broth reduce slightly.
Cook the noodles without overcooking
Break 8 ounces (about half a standard box) of lasagna noodles into 2–3 inch pieces and add them directly to the simmering broth. Stir gently to separate the pieces, then simmer at a low bubble until the noodles are tender but still hold their shape, about 8–10 minutes depending on the noodle brand. Stir occasionally to prevent sticking; taste a piece at 7 minutes to judge doneness. If the broth looks too thick before the noodles are done, add up to 1/2 cup more broth or water.
Finish with the cheese mixture
While the pasta cooks, in a small bowl combine 1 cup ricotta, 1/2 cup grated Parmesan, 1/2 teaspoon freshly ground black pepper, and 1 tablespoon chopped fresh basil (optional). Remove the pot from the heat and let it sit for 30 seconds—this short off-heat pause helps prevent the ricotta from separating. Stir in the ricotta mixture gently so it ribbons through the soup, then sprinkle 1 cup shredded mozzarella on top and let it sit covered for 5 minutes to melt into soft pockets. If you like a more melted result, return the pot to the lowest heat for 1 minute while stirring, but avoid vigorous boiling.
Things I learned the hard way
1. Don’t add the ricotta directly to a rolling boil—my first attempt split the cheese and left an oily sheen; letting the pot cool slightly fixed that.
2. Breaking lasagna noodles helps them fit and cook evenly; whole noodles either clump or require more liquid.
3. Brown the meat well—just sweating it leaves the broth flat.
4. Use a heavy pot so the bottom doesn’t scorch during the initial browning stage.
5. If you like more body, swap half the broth for tomato sauce instead of all crushed tomatoes—this creates a thicker, saucier bowl.
6. Don’t over-salt early if your broth is not low-sodium; leftover reduction concentrates saltiness.
Variations to try
Vegetable-forward: Replace half the meat with finely chopped mushrooms and shredded carrots; sauté until mushrooms release their liquid before adding tomatoes, and cook the noodles the same way. Turkey and spinach: Use ground turkey and stir in 4 cups baby spinach at the end until wilted; add an extra 1/4 cup broth if the spinach soaks up liquid. Spicy sausage version: Substitute 1 pound mild Italian turkey sausage (removed from casings) and reduce red pepper flakes; brown and proceed as written—expect slightly faster browning due to higher fat. Cheesy baked finish: Transfer the simmered soup to an ovenproof dish, top with extra mozzarella and broil 3–4 minutes until bubbly and browned (watch closely).
Storage, freezing, and reheating
Refrigerate leftovers in an airtight container for up to 3 days. The noodles will continue to soften in the fridge, so for best texture, store the broth separately from the pasta if you plan to keep it longer. This soup freezes well if you freeze it before adding the ricotta and mozzarella—freeze in a freezer-safe container up to 3 months. Thaw overnight in the fridge, reheat gently on the stovetop adding extra broth to loosen, then stir in the ricotta mixture and shredded mozzarella to serve. To reheat a refrigerated full soup, warm over medium-low stirring frequently for 6–8 minutes until hot, adding 1/4 cup water or broth if too thick.
What to serve with lasagna soup
Serve with a simple green salad dressed with lemon and olive oil, garlic bread or toasted baguette slices for dipping, and a light marinated vegetable side like roasted zucchini. For a heartier meal, pair with a bowl of steamed green beans tossed with butter and lemon zest. A small plate of olives or marinated artichokes is also a nice bright contrast to the creamy spoonable broth.

Equipment
Method
- Heat olive oil in a 5–6 quart Dutch oven over medium-high heat until shimmering; add the ground meat and cook, breaking into small pieces, until browned and no longer pink, about 6–8 minutes, then drain excess fat if more than 1 tablespoon remains.
- Reduce heat to medium and add the diced onion and minced garlic; sauté until the onion is translucent, about 4 minutes.
- Stir in tomato paste and cook 1 minute, then add the chicken broth, crushed tomatoes, diced tomatoes with juices, oregano, basil, red pepper flakes if using, and kosher salt; bring to a gentle simmer and cook uncovered for 10 minutes.
- Break the lasagna noodles into 2–3 inch pieces and add to the simmering broth; simmer gently until the noodles are tender but not mushy, about 8–10 minutes, stirring occasionally and adding up to 1/2 cup extra broth if the soup becomes too thick.
- In a small bowl, mix ricotta, grated Parmesan, black pepper, and chopped basil; remove the pot from heat and wait 30 seconds, then stir the ricotta mixture into the soup gently so it ribbons through, sprinkle shredded mozzarella on top, cover and let sit 5 minutes to melt, then serve with extra cheese if desired.
Notes
Frequently asked questions
Can I make lasagna soup vegetarian? Yes—replace the meat with a mixture of chopped mushrooms, zucchini, and lentils or use a plant-based meat alternative; brown the vegetables to build flavor and adjust seasoning.
Can I use regular pasta instead of lasagna noodles? Yes—short pasta like penne or broken spaghetti works; shorten or lengthen cooking time according to the pasta package and reduce liquid by about 1/2 cup if using smaller shapes.
Why did my soup become watery? If the noodles were added too early or the pot simmered too long without reduction, the broth can thin; reduce uncovered until slightly thickened or finish with a tablespoon of tomato paste.
Can I prepare this ahead? You can make the broth and meat base 1–2 days ahead and store in the fridge; add and cook the noodles only when ready to serve to preserve texture.
How do I stop the ricotta from separating? Stir the ricotta in off-heat and allow a short rest; using whole-milk ricotta helps stability compared with very low-fat versions.
Closing
Lasagna soup gives you the comforting lasagna flavors with fewer dishes and a reliably creamy finish when you follow the off-heat ricotta step; it’s an ideal weeknight solution when you want that saucy, cheesy satisfaction without a long bake. Serve hot with crusty bread, and refrigerate leftovers separately when possible to keep the texture of the noodles at its best.
