What You Need From Your Kitchen

Large Dutch Oven or Heavy-Bottomed Pot

The thick base prevents scorching while the high sides contain splatter as you brown the sausage and simmer the soup, ensuring even heat distribution for perfectly cooked pasta

Wooden Spoon or Sturdy Spatula

Essential for breaking up the sausage into bite-sized crumbles and stirring the soup without scratching your pot's surface

Sharp Chef's Knife

Makes quick work of chopping fresh parsley and any additional vegetables you want to add, ensuring uniform pieces that cook evenly

Ladle

Allows you to serve generous portions without making a mess, and helps you distribute the ingredients evenly so everyone gets sausage, pasta, and broth in every bowl

Box Grater

Freshly shredded Parmesan and mozzarella melt better and taste significantly more vibrant than pre-shredded varieties, creating that authentic melted cheese experience

Perfect Pairings

Garlic Bread with Herb Butter

The crusty, buttery bread is perfect for soaking up every last drop of the rich tomato broth while adding a satisfying crunch to contrast the soup's tender texture

Caesar Salad with Crispy Romaine

The cool, crisp lettuce and tangy dressing provide a refreshing counterpoint to the warm, hearty soup, cleansing your palate between spoonfuls

Chianti or Sangiovese Wine

These medium-bodied Italian red wines complement the tomato base and Italian sausage beautifully, with enough acidity to cut through the richness without overwhelming the flavors

Roasted Brussels Sprouts with Balsamic Glaze

The caramelized, slightly bitter sprouts add a sophisticated vegetable element that balances the soup's comforting richness

Tiramisu or Cannoli for Dessert

Continue the Italian theme with a classic sweet ending that feels authentic without being too heavy after this satisfying soup

  • 1 pound Italian sausage (mild or spicy)
  • 1 medium yellow onion, diced
  • 4 cloves garlic, minced
  • 1 can (28 ounces) crushed tomatoes
  • 1 can (14.5 ounces) diced tomatoes with juice
  • 4 cups chicken broth or stock
  • 2 teaspoons Italian seasoning blend

  1. 1
    Brown the Sausage
    Remove the sausage from its casing and add it to your large Dutch oven over medium-high heat, breaking it apart with your wooden spoon into small, bite-sized crumbles as it cooks for about 6-7 minutes until no pink remains and the meat develops golden-brown edges that will add incredible depth to your soup base.
  2. 2
    Sauté the Aromatics
    Add the diced onion to the pot with the cooked sausage and cook for 4-5 minutes until the onion turns translucent and soft, then stir in the minced garlic and cook for just one additional minute until fragrant, being careful not to burn the garlic which can turn bitter quickly.
  3. 3
    Build the Tomato Base
    Pour in both the crushed and diced tomatoes along with the chicken broth, then sprinkle in the Italian seasoning, stirring everything together to combine thoroughly and scraping up any flavorful browned bits stuck to the bottom of the pot that developed during the sausage browning process.
  4. 4
    Simmer and Develop Flavors
    Bring the soup to a gentle boil, then reduce the heat to medium-low and let it simmer uncovered for 15 minutes, allowing the flavors to meld together beautifully while the tomatoes break down further, creating a rich, cohesive broth that tastes like it's been simmering all day long.
  5. 5
    Cook the Pasta
    Break the lasagna noodles into roughly 2-inch pieces and add them directly to the simmering soup, stirring occasionally to prevent sticking, and cook for 10-12 minutes until the noodles are tender but still have a slight bite, remembering they'll continue softening slightly even after you remove the pot from heat.
  6. 6
    Season to Perfection
    Taste your soup and adjust the seasoning with salt and freshly ground black pepper as needed, keeping in mind that the Parmesan cheese you'll add as a topping is quite salty, so it's better to slightly under-season at this stage than to overdo it.
  7. 7
    Prepare for Serving
    Remove the pot from heat and let it rest for 2-3 minutes, allowing the soup to cool just slightly and the flavors to settle, which also prevents the cheese from completely melting into the broth rather than creating that gorgeous, gooey topping layer you're looking for.
  8. 8
    Garnish and Serve
    Ladle the hot soup into deep bowls, then immediately top each serving with a generous handful of shredded mozzarella, a sprinkle of freshly grated Parmesan, and a scattering of chopped fresh parsley that adds a pop of color and a bright, herbaceous note to balance the richness.

Chef's Notes

  • For a lighter version, substitute turkey or chicken sausage for the pork Italian sausage without sacrificing much flavor, though the soup will have a slightly less rich taste overall.
  • Break the lasagna noodles before adding them to ensure they're spoon-friendly and easy to eat, rather than trying to manage long, unwieldy strips in your soup bowl.
  • Don't add the pasta too early or it will become mushy and overcooked, absorbing too much liquid and turning your soup into more of a thick stew consistency than intended.
  • This soup thickens considerably as it sits because the pasta continues absorbing liquid, so add extra broth when reheating leftovers to restore the proper soup consistency you enjoyed originally.
  • Freshly grated cheese melts far better than pre-shredded varieties which contain anti-caking agents that prevent smooth melting, so take the extra minute to grate your own for superior results.
  • Add a pinch of red pepper flakes along with the Italian seasoning if you prefer more heat, or use spicy Italian sausage instead of mild for an extra kick.

Frequently Asked Questions

Absolutely! This soup is fantastic for meal prep, though I recommend storing the cooked pasta separately from the broth if possible to prevent it from becoming too soft. The soup base actually develops even more flavor after a day in the refrigerator as the seasonings meld together. When ready to serve, gently reheat on the stovetop, adding extra broth to thin it out since the pasta will have absorbed liquid during storage, then add your fresh cheese and parsley toppings just before serving.

The key is timing and temperature control. Add your broken lasagna noodles only after the soup has simmered and developed its flavors, then cook them just until al dente since they'll continue softening in the hot broth. If you're planning to have leftovers, consider slightly undercooking the pasta initially. For meal prep enthusiasts, cooking the pasta separately and adding it to individual portions as you reheat ensures perfect texture every time, though it does require an extra pot.

While lasagna noodles are traditional and give this soup its authentic character, you can absolutely substitute other pasta shapes. Wide egg noodles, campanelle, or even broken-up oven-ready lasagna sheets work beautifully. Mafalda or mafaldine pasta ribbons create a similar appearance with their ruffled edges. Just keep the cooking time in mind as different shapes require different amounts of time to reach that perfect tender-but-not-mushy consistency we're looking for.

Transform this into a satisfying vegetarian lasagna soup by replacing the Italian sausage with a combination of sautéed mushrooms and crumbled firm tofu or plant-based sausage alternatives. Add extra vegetables like diced zucchini, bell peppers, or spinach to boost nutrition and maintain that hearty, filling quality. Use vegetable broth instead of chicken broth, and consider stirring in some ricotta cheese dollops just before serving to mimic that classic lasagna creaminess while adding protein to keep the soup substantial and satisfying.

Restaurant-style lasagna soups often appear thicker because they've been sitting in a steam table where the pasta continues absorbing liquid. To achieve a thicker consistency at home, reduce the amount of broth slightly or let your soup simmer a bit longer after adding the pasta. Some cooks also add a tablespoon of tomato paste for extra body and deeper tomato flavor. Remember that the soup will naturally thicken as it cools and the starches from the pasta release into the broth, creating a more cohesive texture.

While mozzarella and Parmesan are the classic choices that authentically represent traditional lasagna, don't be afraid to experiment with other Italian cheeses for variety. A dollop of creamy ricotta adds luxurious smoothness, while provolone provides a sharper, more complex flavor. For an extra-indulgent version, try a combination of fontina and asiago cheeses. Whatever you choose, always use freshly grated or shredded cheese rather than pre-packaged varieties, as the anti-caking agents in pre-shredded cheese prevent that gorgeous melty consistency you're craving.
