Why I Love This Recipe

I love classic lasagna, but this soup gives me those same saucy, cheesy flavors without all the layering. The broken lasagna noodles cook right in the crockpot, then ricotta, mozzarella and Parmesan finish each bowl.

For more easy twists on lasagna night, my lasagna casserole and skillet lasagna are two more family favorites.

  • Onion and garlic: Sauté diced onion with minced garlic alongside the sausage to build a flavorful Italian base for the soup.
  • Sausage: Make this extra Italian with sausage or a more American traditional ground beef.
  • Chicken stock: This gives the soup a rich base without overpowering the flavors. You can also use chicken broth for a lighter taste or beef broth for a heartier flavor.
  • Tomatoes: Both petite diced tomatoes with juice and tomato paste are used for the Italian flavor and base. It is a rich sauce that helps add the traditional Italian flavoring.
  • Seasonings and herbs: A mix of Italian seasoning, oregano, and fresh basil gives the soup its classic Italian flavor. Add a pinch of red pepper flakes if you like a little heat.
  • Lasagna noodles: Break the noodles into bite-size pieces before adding them to the crockpot. They cook right in the soup and give you that classic lasagna texture in every spoonful, without needing to cut through big sheets.
  • Cheese: Freshly grated parmesan and mozzarella melt right into the soup, giving it that classic cheesy, gooey pull you’d expect from lasagna. For the full effect, I love adding a dollop of ricotta on top when serving.

How to Make Crockpot Lasagna Soup

Step 1: In a large pot, heat the olive oil over medium heat. Add onion and cook for 2 to 3 minutes. Stir in the garlic and cook for an additional minute. Add sausage, breaking into pieces with a wooden spoon, and cook until browned.

Recipe Tips

  • Timing. Cook on low for 3 to 4 hours or on high for 2 to 3 hours, depending on your schedule.
  • Thinner soup. For a soupier consistency, stir in an extra 1/2 to 1 cup broth or hot water.
  • Noodles. If using cooked al dente noodles, stir them in near the end just to heat through. You can also use gluten-free noodles or another pasta shape like farfalle.
  • Meat. Swap mild Italian sausage for spicy sausage if you like a little heat. Ground beef or turkey also works well. Add an extra 1/2 teaspoon Italian seasoning for more flavor.
  • Veggies. Add shredded carrots, bell peppers, mushrooms or zucchini. You can also stir in baby spinach near the end, like I do in my white lasagna soup.

Serving Suggestions

  • Bread. My family loves to dip garlic bread or this easy breadstick recipe into a warm bowl of crockpot lasagna soup.
  • Antipasto: Pair with a simple Italian antipasto platter for a fun starter. It’s the perfect way to round out a cozy meal.
  • Garnish: Set out bowls of parmesan, ricotta, and fresh basil so everyone can top their crockpot lasagna soup just the way they like it.

Crockpot Lasagna Soup Recipe FAQs

Can I make this soup in advance?

Yes! If preparing ahead, cook the noodles separately and add them just before serving. This prevents them from getting too soft. If you’re enjoying it the same day, the noodles can simmer right in the soup.

What are the best noodles for lasagna soup?

Traditional lasagna noodles work best because they give the soup that classic lasagna feel. Break them into smaller pieces before adding them to the crockpot. You can also use mafaldine, cellentani, farfalle or another sturdy pasta shape.

What stock is best for lasagna soup?

Chicken stock works best because it adds plenty of flavor without overpowering the sausage and tomato base. You can also use low-sodium chicken broth, or even beef broth for a meatier flavor.

Can I take the lid off to thicken lasagna soup?

Yes. If the soup is thinner than you’d like, remove the lid and let it cook for about 15 to 30 minutes so some of the liquid can evaporate. Keep in mind the soup will also thicken as the noodles absorb more broth.
