One-Pot Lasagna Soup Recipe tastes like a cozy bowl of saucy, cheesy lasagna that decided to ditch the layering and jump straight into comfort mode. It works perfectly for busy families, lazy Sunday cooks, or anyone who wants weeknight lasagna flavor in about 40 minutes, start to finish. I first made this on a cold week in Chicago, and my kids now request it more often than actual lasagna.

Why Choose This One-Pot Lasagna Soup Recipe

This One-Pot Lasagna Soup Recipe gives you all the classic lasagna flavors without the fuss of boiling noodles separately or stacking layers. You brown, simmer, and finish everything in one pot, which means fewer dishes and more couch time.

The soup tastes rich, cheesy, and tomato-forward with tender pasta and bits of ground meat in every spoonful. You can keep it mild and kid friendly or bump up the seasoning for a spicier version.

Ingredients You’ll Need

Protein

1 pound Italian sausage, casings removed
- Use mild for kids or hot for more heat.
- Swap with ground beef, ground turkey, or a 50/50 mix if you prefer.
1 tablespoon olive oil, only if your meat looks very lean

Aromatics

1 medium yellow onion, finely diced
4 cloves garlic, minced
1 teaspoon kosher salt, plus more to taste
½ teaspoon black pepper

Tomato base

2 tablespoons tomato paste
- I like the tube style because it stores easily in the fridge.
1 can (28 ounces) crushed tomatoes
- Use a good brand like Cento or Muir Glen for richer flavor.
1 can (14.5 ounces) diced tomatoes, with juices
- Fire-roasted tomatoes add a subtle smoky note.

Broth and dairy

4 cups low-sodium chicken broth or vegetable broth
1 cup water, as needed to adjust thickness
1 cup whole milk or half-and-half
- This softens the acidity and adds a creamy finish.

Pasta

8 to 10 lasagna noodles, broken into bite-size pieces
- You can use regular, whole wheat, or gluten-free lasagna noodles.
- Use about 6 ounces of any short pasta if you do not have lasagna noodles.

Seasonings

2 teaspoons dried Italian seasoning
1 teaspoon dried basil
1 teaspoon dried oregano
½ to 1 teaspoon crushed red pepper flakes, optional
1 teaspoon sugar, optional, to balance acidity if needed

Cheesy topping

1 cup ricotta cheese
1 cup shredded mozzarella cheese
¼ cup grated Parmesan cheese
2 tablespoons chopped fresh parsley or basil, plus more for garnish
Pinch of salt and pepper for the ricotta mixture

Pantry shortcuts and substitutions

Use jarred marinara sauce instead of crushed tomatoes and tomato paste if you want a shortcut. Replace both with 3 cups of your favorite marinara and reduce added salt.
Use pre-shredded mozzarella if you feel tired, although freshly shredded melts creamier.
Use frozen chopped onions and jarred minced garlic on extra busy nights.

Equipment list

Large heavy-bottomed pot or Dutch oven (at least 5 to 6 quarts)
Wooden spoon or spatula
Ladle
Measuring cups and spoons
Small bowl for the ricotta topping

Tips & Tricks

Brown the meat deeply so the bottom of the pot develops browned bits that add rich flavor to the soup.
Break the lasagna noodles into similar sizes so they cook evenly and fit on your spoon.
Add the pasta near the end and keep the soup at a gentle simmer so the noodles stay tender but not mushy.
Stir often after adding pasta so it does not stick to the bottom of the pot.
Taste the broth before adding sugar, since some tomato brands taste naturally sweet enough.
Keep the soup slightly thinner than you like before adding pasta, because the noodles soak up liquid as they cook.
Add the dairy at the end over low heat so it stays smooth and does not curdle.
Store the ricotta mixture separate from the soup so it stays fresh and creamy for topping.
Use leftover cooked pasta if you have some; stir it in during the last 3 to 4 minutes just to heat through.
Keep extra broth or water on hand to loosen leftovers, since the pasta continues to absorb liquid in the fridge.

How to Make One-Pot Lasagna Soup Recipe

Step 1: Brown the meat

Heat a large pot over medium-high heat. Add the Italian sausage and break it into small crumbles with a spoon. Cook until the meat browns and no pink remains, about 6 to 8 minutes, then spoon off excess fat if the pot looks very greasy.

Step 2: Sauté the aromatics

Add the diced onion to the pot with the sausage and stir. Cook until the onion softens and turns translucent, about 4 to 5 minutes. Add the minced garlic, salt, and black pepper, then cook 1 more minute so the garlic turns fragrant but not browned.

Step 3: Build the tomato base

Stir in the tomato paste and cook it for 1 to 2 minutes so it darkens slightly and concentrates in flavor. Add the crushed tomatoes and diced tomatoes with their juices. Scrape the bottom of the pot as you stir so you lift up all the browned bits into the sauce.

Step 4: Add broth and seasonings

Pour in the chicken broth and 1 cup of water and stir. Add Italian seasoning, dried basil, dried oregano, and crushed red pepper flakes if you use them. Bring the mixture to a gentle boil, then reduce the heat to a steady simmer.

Step 5: Simmer the base

Let the soup base simmer for about 10 minutes, uncovered, so the flavors blend. Taste and adjust salt and pepper, and add the teaspoon of sugar if the tomatoes taste very sharp or acidic. Keep the soup at a low bubble while you prep the pasta and cheese mixture.

Step 6: Add the lasagna noodles

Break the lasagna noodles into small pieces, about 1 to 2 inches each. Stir the noodle pieces into the simmering soup so they submerge fully. Cook, stirring often, for 10 to 12 minutes or until the pasta turns al dente and tender.

Step 7: Make the ricotta topping

While the pasta cooks, mix the ricotta, mozzarella, Parmesan, chopped parsley or basil, and a pinch of salt and pepper in a small bowl. Stir until the mixture looks creamy and spreadable. Taste and adjust seasoning so it tastes flavorful on its own.

Step 8: Finish with dairy

When the pasta reaches al dente, lower the heat to medium-low. Stir in the milk or half-and-half and let the soup heat gently for 2 to 3 minutes. Do not let it boil hard at this stage so the dairy stays smooth and silky.

Step 9: Adjust thickness and season

Check the consistency of the soup and add a splash of water or broth if it looks too thick. Taste and adjust salt, pepper, and red pepper flakes until the flavor hits you with that lasagna comfort. Turn off the heat and let the soup sit for 3 to 5 minutes so it thickens slightly.

Step 10: Serve with cheesy dollops

Ladle the One-Pot Lasagna Soup into bowls. Add a generous scoop of the ricotta mixture on top of each bowl so it melts slightly into the hot soup. Sprinkle with extra Parmesan and fresh herbs if you like, then serve hot.

What to Serve with One-Pot Lasagna Soup Recipe

This One-Pot Lasagna Soup Recipe pairs nicely with a simple green salad tossed with olive oil, lemon, and a pinch of salt. Add warm garlic bread, breadsticks, or a crusty baguette so you can scoop up every last bit of sauce. Kids love it with a side of steamed broccoli or green beans, which also balances the richness of the soup. Serve with sparkling water, flavored seltzer, or iced tea for a refreshing contrast.

Storage Options

Store leftover soup in an airtight container in the fridge for up to 4 days.
Keep the ricotta topping in a separate container in the fridge for up to 3 days.
Reheat soup gently on the stove over medium-low heat, adding a splash of broth or water to loosen it as the pasta thickens the liquid.
Use the microwave for single bowls, heating in 45 to 60 second bursts and stirring between each round.
Freeze the soup without the pasta for best texture, up to 3 months, then add freshly cooked pasta when you reheat.
If you freeze the soup with pasta, expect softer noodles; thaw overnight in the fridge and reheat slowly with extra broth.
