Easy Crockpot Lasagna Soup

This crockpot lasagna soup has all the cozy flavors of a classic lasagna, but in an easy slow cooker recipe that’s perfect for busy weeknights. My family loves the rich tomato broth, hearty sausage, noodles, and gooey cheese and it’s so simple in my crock pot!

It’s the hands-off version of my stovetop lasagna soup, and every bit as delicious. If you love making crockpot lasagna but want a simpler, fuss-free way to enjoy those same Italian flavors in a comforting soup recipe this will become a new favorite for family dinners.

Ingredients for Slow Cooker Lasagna Soup

Lasagna soup ingredients laid out on a white surface, including sausage, lasagna noodles, tomato paste, canned tomatoes, broth, cheese, onion, and seasonings.

  • 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-by-step photos showing how to make lasagna soup in the slow cooker— browning sausage, adding broth and herbs, simmering with noodles, and serving.
  1. Brown meat. 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.
  2. Combine. Transfer sausage mixture to a 4 to 6-quart crockpot. Stir in chicken stock, tomatoes, and tomato paste until combined. Add the oregano, Italian seasoning, and basil. Cook on low for 3 to 4 hours or high for 2 to 3 hours.
  3. Add the noodles. If you prefer more liquid, stir in an extra 1/2 to 1 cup hot water or broth. Cover and cook for an additional 30 minutes, or until noodles are tender.
  4. Stir cheese and serve. Stir in the parmesan, mozzarella, salt, and pepper then ladle soup into bowls.

Tips and Variations

  • Timing. It can be cooked on low for 3 to 4 hours or on high for 2 to 3 hours. Base the time off on what you’ve got going on and when you want to eat!
  • Thin soup. If you like yours a little thinner and soupier, add in about 1/2 cup to 1 cup more broth or hot water.
  • Noodles. If using already cooked al dente noodles, toss them in towards the end to heat through. Use gluten-free noodles or even farfalle noodles.
  • Meat: If you like a little heat, substitute the mild sausage for spicy one. Try ground beef or ground turkey along with 1/2 teaspoon extra Italian seasoning.
  • Veggies: Add extra nutrition with shredded carrots, bell peppers, mushrooms, or zucchini. You can also stir in baby spinach, just 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.

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.

Can you use a different type of pasta?

Absolutely. Lasagna noodles give the most authentic flavor and texture, but you can swap in pasta like elbows, spirals, or cellentani if that’s what you have on hand.

How to store crockpot lasagna soup?

Place leftovers in an airtight container and refrigerate for 3–4 days. Reheat on the stovetop or in the microwave until warmed through.

Can you freeze crockpot lasagna soup?

Yes! For the best texture, freeze the soup without the pasta. Let the base cool, then transfer to freezer-safe containers and store for up to 3 months. Thaw in the fridge overnight, reheat, and stir in freshly cooked noodles before serving.
