Ingredients You’ll Need
The ingredient list is straightforward, but each item has an important job. Choose mild sausage for a family-friendly bowl or hot sausage when you want a little more spice.
- Olive oil: Helps begin the browning process and keeps the sausage from sticking.
- Italian sausage: Adds seasoning and savory flavor throughout the broth. Ground beef can be substituted, or you can use half ground beef and half Italian sausage.
- Onion and garlic: Create the aromatic foundation of the soup.
- Tomato paste and canned tomatoes: Give the broth a concentrated, rich tomato flavor.
- Broth: Use chicken broth or beef broth, depending on the flavor you prefer.
- Lasagna noodles: Break about 8 sheets into uneven bite-size pieces so they are easy to eat.
- Ricotta, mozzarella, and Parmesan: Form the classic lasagna-style topping.
- Parsley or basil: Adds fresh color and a bright finish.
For extra vegetables, add spinach, zucchini, or chopped mushrooms with the onions. These additions are optional and should not replace the listed tomatoes, broth, or noodles.

How to Make It Step-by-Step
Step 1: Heat the olive oil in a large Dutch oven or soup pot over medium-high heat. Add the sausage and cook for 5-7 minutes, breaking it into small pieces with a wooden spoon as it browns. If the sausage releases a large amount of fat, carefully drain the excess before continuing.
Step 2: Add the diced yellow onion to the browned sausage and cook for 3-4 minutes. Stir occasionally until the onion softens and begins to look translucent, then add the minced garlic and cook for about 30 seconds.
Step 3: Stir the tomato paste, Italian seasoning, and optional red pepper flakes into the sausage and onion mixture. Cook for 1 minute, stirring constantly, so the tomato paste lightly caramelizes and coats the ingredients.
Step 4: Pour in the crushed or diced tomatoes and 6 cups of chicken broth or beef broth. Add the bay leaf, kosher salt, and black pepper, then stir well and bring the soup to a boil.
Step 5: Break the lasagna noodles into uneven bite-size pieces and add them directly to the boiling soup. Reduce the heat to medium-low and simmer uncovered for approximately 10-15 minutes, stirring occasionally so the noodles do not clump together or stick to the bottom.
Step 6: Check the noodles for tenderness and remove the bay leaf. Taste the broth and adjust the salt and pepper as needed, keeping in mind that the Parmesan will add additional salt when served.
Step 7: Combine the ricotta, shredded mozzarella, and grated Parmesan in a small bowl, or keep them separate for individual toppings. Ladle the hot soup into bowls and finish each serving with the cheese mixture and chopped parsley or basil.
Chef’s Tips for the Best Texture
Break the lasagna noodles into pieces of slightly different sizes rather than making every piece identical. This gives the soup a rustic appearance and makes it easier to scoop up noodles, sausage, and broth together.
Stir the pot regularly while the noodles cook. Lasagna noodles release starch as they simmer, and that starch can cause pieces to stick together or absorb broth quickly.
Serve the soup soon after the noodles become tender. If it stands for a long time, the pasta will continue absorbing liquid and may become too soft.
For the creamiest bowl, add the cheese at serving instead of stirring all of it into the pot. The ricotta, mozzarella, and Parmesan melt gradually into each portion while keeping the broth pleasantly loose.
Do not skip the brief tomato paste cooking step. One minute in the hot pot helps deepen its flavor and gives the soup a fuller, more developed tomato base.
Easy Substitutions and Variations
Ground beef may replace the Italian sausage if that is what you have available. For a richer combination, use half ground beef and half Italian sausage, adjusting the final seasoning after the broth simmers.
Marinara sauce can also be used in place of the tomato paste and canned tomatoes. Use approximately 4 cups of marinara sauce with 4-6 cups of broth, then taste before adding extra salt because prepared sauces vary.
If you do not have Italian seasoning, use 1 teaspoon dried basil and 1 teaspoon dried oregano. Spinach, zucchini, and chopped mushrooms are welcome additions and can be cooked with the onion before the liquids are added.
Serve the soup with a simple green salad or warm garlic bread. For dessert, a slice of this homemade chocolate pudding pie makes a wonderful finish to a comforting dinner.
Storage and Reheating
Store leftover soup in an airtight container in the refrigerator and enjoy it soon after cooking for the best noodle texture. The pasta will absorb more broth as it sits, so the leftovers may be thicker than the freshly cooked soup.
When preparing the soup ahead, cook the noodles separately and add them to individual bowls just before serving. This keeps the pasta from becoming overly soft and lets you adjust the amount of broth in each portion.
Reheat gently on the stovetop, adding a splash of broth if the soup has thickened. Stir often and add fresh cheese toppings after the soup is hot.
