Ingredients You Need

Main ingredients

Olive oil
Ground Italian sausage or ground beef
- Use mild Italian sausage for classic flavor.
- Swap in ground turkey or chicken if you want something lighter.
Yellow onion, diced
Garlic, minced
Tomato paste
Crushed tomatoes (canned)
- I like San Marzano style for sweeter, richer sauce.
Low sodium chicken broth or vegetable broth
Water, as needed to thin the soup
Lasagna noodles, broken into bite-size pieces
- You can use regular, whole wheat, or gluten free lasagna noodles.
Italian seasoning
Dried basil and dried oregano
Red pepper flakes (optional, for a little heat)
Salt and black pepper

Cheesy topping

Whole milk ricotta cheese
Shredded mozzarella cheese
Grated Parmesan cheese
Fresh parsley or basil, chopped
A pinch of salt and pepper

Pantry shortcuts and substitutions

Use jarred marinara sauce instead of crushed tomatoes and tomato paste if you want a shortcut. Just reduce the salt a bit.
Use garlic powder and onion powder if you run out of fresh garlic and onion. The flavor stays great, just add a bit more to taste.
Use small pasta shapes like mafalda, rotini, or bow ties if you do not have lasagna noodles. The soup still tastes like lasagna, just with different shapes.
Use low fat ricotta and part skim mozzarella if you want a lighter bowl that still tastes cheesy and rich.

Equipment list

Large heavy-bottomed pot or Dutch oven (at least 5 to 6 quarts)
Wooden spoon or sturdy spatula
Ladle
Small bowl for mixing the cheese topping
Measuring cups and spoons
Sharp knife and cutting board

Tips & Mistakes

Brown the meat well so you build deep flavor instead of pale, bland crumbles.
Drain extra fat if your sausage or beef releases a lot, so the soup tastes rich but not greasy.
Toast the tomato paste in the pot for a minute or two so it tastes sweet and concentrated, not metallic.
Break the lasagna noodles into similar sizes so they cook evenly and do not clump.
Stir the soup often after you add the noodles so they do not stick to the bottom of the pot.
Keep the soup at a gentle simmer, not a hard boil, so the noodles stay tender and do not fall apart.
Taste and season near the end of cooking since broth, tomatoes, and sausage all bring different salt levels.
Add the cheesy topping to each bowl right before serving so the soup stays brothy and the cheese stays creamy.
Do not overcook the noodles if you plan to store leftovers, since they will soften more in the fridge.
Add extra broth or water when reheating leftovers because the noodles soak up liquid overnight.

How to Make One-Pot Lasagna Soup Recipe

Step 1: Brown the meat and build the base

Heat a large pot over medium high heat and drizzle in olive oil. Add the ground Italian sausage or beef and break it up with a spoon while it cooks. Cook until the meat browns and little crispy bits form on the bottom of the pot.

Add the diced onion and cook until it softens and turns translucent. Stir in the minced garlic and cook about 30 seconds until it smells fragrant. Spoon off extra fat if the pot looks very greasy.

Step 2: Toast the tomato paste and spices

Add the tomato paste to the pot and stir it into the meat and onions. Cook it for 1 to 2 minutes so it darkens slightly and tastes richer. Sprinkle in Italian seasoning, dried basil, dried oregano, red pepper flakes, salt, and black pepper.

Stir the spices into the tomato paste and meat so everything gets coated. This step wakes up the dried herbs and gives the soup a deeper, slow cooked flavor even though it cooks quickly.

Step 3: Add liquids and simmer

Pour in the crushed tomatoes and chicken broth. Scrape the bottom of the pot with your spoon to lift up all the browned bits. Add a little water if the mixture looks very thick, since the noodles will soak up liquid later.

Bring the pot to a gentle boil, then lower the heat to a steady simmer. Let the soup simmer for about 10 minutes so the flavors blend. Taste and adjust the seasoning with more salt, pepper, or red pepper flakes.

Step 4: Add the noodles

Break the lasagna noodles into bite-size pieces, about 1 to 2 inches long. Drop them into the simmering soup and stir well so they spread out and do not clump. Keep the heat at a gentle simmer.

Cook the noodles according to the package time, usually 10 to 12 minutes, until they turn tender but still hold a little bite. Stir often and add a splash of water or broth if the soup thickens too much. You want a hearty, spoonable soup, not a solid pasta situation.

Step 5: Mix the cheese topping

While the noodles cook, grab a small bowl. Add ricotta, shredded mozzarella, grated Parmesan, chopped parsley or basil, and a pinch of salt and pepper. Stir until the mixture turns creamy and well combined.

This mixture acts like the cheesy top layer of lasagna. You will dollop it on each bowl instead of stirring it into the whole pot. That way everyone can choose how cheesy they want their soup.

Step 6: Finish and serve

When the noodles reach your preferred tenderness, turn off the heat. Taste the soup again and tweak the seasoning if needed. Ladle the hot One-Pot Lasagna Soup Recipe into bowls.

Add a generous spoonful of the ricotta cheese mixture on top of each bowl. The heat from the soup softens the cheese and gives you that classic lasagna vibe. Sprinkle extra Parmesan and fresh herbs on top if you feel fancy.

Variations I've Tried

Veggie loaded version
Add diced zucchini, mushrooms, and spinach after the onions soften. Sauté the veggies for a few minutes, then continue with the recipe. This version tastes hearty and works great when you want more vegetables without losing the lasagna feel.
Spicy version
Use hot Italian sausage and extra red pepper flakes. Add a pinch of smoked paprika for a deeper, slightly smoky flavor. This version hits like a cozy bowl of lasagna with a little kick.
Lighter protein version
Use ground turkey or chicken instead of sausage or beef. Add a splash of extra olive oil so the flavor stays rich. Use part skim cheeses and extra herbs for brightness.
Gluten free version
Use gluten free lasagna noodles or another gluten free pasta shape. Stir gently, since some gluten free noodles break more easily. Check the noodles a bit early, since they can go from firm to soft quickly.
Dairy free twist
Skip the cheese topping and stir in a splash of unsweetened cashew or oat milk at the end for a touch of creaminess. Top each bowl with a sprinkle of nutritional yeast and fresh herbs. The soup still tastes rich and tomato forward.

How to Serve One-Pot Lasagna Soup Recipe

Serve this One-Pot Lasagna Soup Recipe piping hot with a big dollop of the ricotta mixture on top and extra Parmesan on the side. Add a simple green salad or steamed vegetables to balance the richness. Warm garlic bread, breadsticks, or crusty rolls make perfect partners for dunking and scooping up every last bit of sauce. Kids usually love this because it tastes like lasagna but feels easier and more fun to eat with a spoon.

How to store

Cool the soup to room temperature, then store it in airtight containers in the fridge for up to 4 days.
Keep the cheese mixture in a separate container in the fridge for the same amount of time so it stays thick and creamy.
Freeze the soup without the cheese topping for up to 2 months in freezer safe containers, leaving a little space at the top for expansion.
Reheat on the stove over medium heat, adding a splash of broth or water as the noodles soak up liquid, and stir often until hot.
Reheat single portions in the microwave in short bursts, stirring between each burst, then top with the ricotta mixture right before serving.
