If you love lasagna but not the layering, the waiting, or the mountain of dishes, Viral Lasagna Soup is about to become your new weeknight obsession. This is the one-pot soup that took TikTok and Instagram by storm: everything you love about classic lasagna — rich tomato broth, savory Italian sausage, tender pasta, and a creamy, cheesy finish — simmered together in a single pot and ready in about 40 minutes.
The magic is in the details. Broken lasagna noodles cook right in the broth, soaking up all that tomato and herb flavor, while a generous dollop of seasoned ricotta melts into each bowl along with stretchy mozzarella and fresh basil. It tastes like a lasagna that decided to be cozy soup instead, and it is every bit as comforting as the original — without a single layer to assemble.

Ingredients
For the Soup:
- 1 tablespoon olive oil
- 1 pound Italian sausage (sweet or hot), casings removed
- 1 medium yellow onion, finely diced
- 3 cloves garlic, minced
- 1 teaspoon Italian seasoning
- 1/2 teaspoon red pepper flakes (optional, for heat)
- 1 tablespoon tomato paste
- 1 can (28 ounces) crushed tomatoes
- 4 cups low-sodium chicken broth (or beef broth)
- 1 cup water
- 8 ounces lasagna noodles, broken into 1- to 2-inch pieces
- 2 cups baby spinach (optional)
- Salt and freshly ground black pepper, to taste
For the Ricotta Topping:
- 1 cup whole-milk ricotta cheese
- 1/2 cup shredded mozzarella cheese
- 1/4 cup grated Parmesan cheese
- 1 tablespoon chopped fresh basil, plus more for garnish
- 1/4 teaspoon salt
- 1/4 teaspoon black pepper
For Serving:
- Extra shredded mozzarella and grated Parmesan
- Fresh basil leaves
- Crusty bread or garlic bread, for dipping
Instructions
- Brown the sausage: Heat the olive oil in a large Dutch oven or heavy-bottomed pot over medium-high heat. Add the sausage and cook, breaking it into small crumbles with a wooden spoon, for 5 to 7 minutes, until browned all over. Drain off any excess fat if needed, leaving about a tablespoon in the pot for flavor.
- Sauté the aromatics: Add the diced onion to the pot and cook for 3 to 4 minutes, until softened and translucent. Stir in the garlic, Italian seasoning, and red pepper flakes and cook for 30 seconds more, just until fragrant.
- Build the tomato base: Stir in the tomato paste and cook for 1 to 2 minutes, letting it darken slightly — this deepens the tomato flavor. Pour in the crushed tomatoes, chicken broth, and water, scraping up any browned bits from the bottom of the pot.
- Simmer the broth: Bring the soup to a boil, then reduce the heat to medium-low and simmer uncovered for 15 minutes. Season with salt and pepper, tasting as you go, since broth and sausage vary in saltiness.
- Cook the noodles: Stir in the broken lasagna noodles, making sure they are mostly submerged. Simmer for 10 to 12 minutes, stirring occasionally so the noodles do not stick together, until they are tender but still have a slight bite. If using spinach, stir it in during the last 2 minutes until just wilted.
- Make the ricotta topping: While the noodles cook, stir together the ricotta, mozzarella, Parmesan, basil, salt, and pepper in a small bowl until well combined.
- Serve: Ladle the hot soup into bowls, being sure to get plenty of noodles and sausage in each serving. Top each bowl with a generous dollop of the ricotta mixture, a sprinkle of extra mozzarella and Parmesan, and fresh basil leaves. Serve immediately with crusty bread for dipping.
Tips for the Best Lasagna Soup
- Break the noodles small: Pieces about 1 to 2 inches long are easiest to eat with a spoon and cook evenly in the broth.
- Do not overcook the pasta: The noodles will keep softening in the hot broth, so pull the pot off the heat when they are just al dente.
- Stir while the noodles cook: Lasagna noodles love to clump together, so give the pot a stir every couple of minutes.
- Season the ricotta: The ricotta dollop is not just a garnish — salting it and adding Parmesan and basil turns it into the creamy, cheesy finish that makes this soup taste like lasagna.
- Use whole-milk ricotta: Low-fat ricotta can turn grainy; whole-milk ricotta stays smooth and rich when it melts into the hot soup.
- Adjust the thickness: If the soup gets too thick as the noodles absorb broth, stir in an extra splash of broth or water until it reaches your preferred consistency.
- Toast the tomato paste: Cooking the tomato paste for a minute or two before adding the liquids removes any tinny taste and adds real depth.
Variations
- Spicy lasagna soup: Use hot Italian sausage and add an extra 1/2 teaspoon of red pepper flakes, or stir in a spoonful of Calabrian chili paste.
- Vegetarian version: Skip the sausage and add a can of drained white beans plus sliced mushrooms and zucchini, sautéed with the onion. Use vegetable broth in place of chicken broth.
- Turkey or chicken lasagna soup: Swap the sausage for ground turkey or ground chicken, and add 1 teaspoon of fennel seeds for that classic Italian sausage flavor.
- Creamy lasagna soup: Stir 1/2 cup of heavy cream into the soup right before serving for an even richer, silkier broth.
- Extra veggie lasagna soup: Add diced carrots and celery with the onion, or stir in kale, mushrooms, or roasted red peppers for a heartier bowl.
Storage & Reheating
Store leftover soup in an airtight container in the refrigerator for up to 4 days. Keep the ricotta topping separate if possible, since the noodles will continue to absorb broth as the soup sits. Reheat gently on the stovetop over medium heat, adding a splash of broth or water to loosen it up, or microwave individual portions in 1-minute intervals, stirring between each, until steaming hot.
For longer storage, freeze the soup (without the ricotta topping) in freezer-safe containers for up to 3 months. Thaw overnight in the refrigerator, then reheat on the stovetop, adding fresh broth as needed, and finish with a fresh ricotta dollop. If you plan to freeze a batch, cook the noodles separately and add them when reheating — frozen pasta tends to go mushy.
Frequently Asked Questions
Can I make lasagna soup ahead of time?
Yes, but for the best texture, cook the noodles separately and store them apart from the soup. Combine them when reheating so the pasta stays tender instead of soaking up all the broth and turning soft. The broth and sausage base actually tastes better the next day, so this is a great make-ahead strategy.
Can I use other pasta shapes instead of lasagna noodles?
Absolutely. Mafalda, broken rigatoni, farfalle, or even rotini all work well. Just cook them in the soup according to the package directions for al dente, and keep in mind that smaller shapes cook faster than lasagna noodles.
Is lasagna soup gluten-free?
As written, no, because of the wheat noodles. To make it gluten-free, simply swap in your favorite gluten-free lasagna noodles or another gluten-free short pasta, and double-check that your broth and sausage are certified gluten-free.
What should I serve with lasagna soup?
Crusty bread or garlic bread is the classic pairing — perfect for scooping up the cheesy broth. A simple green salad with a lemon vinaigrette also balances the richness nicely, and a glass of red wine never hurts.
Whether you are feeding a hungry family on a busy weeknight or just craving something warm, cheesy, and deeply comforting, this viral lasagna soup delivers all the joy of lasagna in a fraction of the time. Ladle it up, add that creamy ricotta dollop, tear off a hunk of crusty bread, and enjoy every single spoonful — no layering required.
