Crock Pot Lasagna Soup Recipe From Scratch

This crock pot lasagna soup gives you all the comfort of a full lasagna with a fraction of the effort. I brown the beef, dump everything into the slow cooker, and walk away for 6 hours. The result is a thick, deeply flavored soup with tender pasta, rich tomato broth, and a ricotta cheese topping that melts into every bowl.

Why This Crock Pot Lasagna Soup Works

The slow cooker does something a stovetop version can’t — it gives the beef, tomatoes, and aromatics hours to merge into a single, layered broth. The fat renders slowly into the base and the tomato paste deepens from sharp and raw to rich and sweet. It tastes like it simmered all day because it did.

Broken lasagna noodles go in during the last 30 minutes so they cook through without turning to mush. Add them too early and the pasta absorbs all the broth and becomes a starchy paste by dinnertime.

The cheesy topping — ricotta, mozzarella, and Parmesan — is what separates this crock pot lasagna soup from regular tomato soup. Add a heaping spoonful to each bowl and stir it in slightly so you get creamy ribbons in every bite.

Ingredients

• 1 lb ground beef (80/20)
• 1 medium yellow onion, diced
• 4 cloves garlic, minced
• 2 tablespoons tomato paste
• 1 can (28 oz) crushed tomatoes
• 1 jar (24 oz) marinara sauce
• 4 cups low-sodium beef broth
• 1 teaspoon dried basil
• 1 teaspoon dried oregano
• 1 teaspoon Italian seasoning
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1/4 teaspoon red pepper flakes
• 8 lasagna noodles, broken into 2-inch pieces
• 1 cup whole milk ricotta cheese
• 1 cup shredded mozzarella cheese
• 1/4 cup grated Parmesan cheese
• Fresh basil for garnish

What You Need for Crock Pot Lasagna Soup

Ground beef (80/20) — the fat content is important here. Lean ground beef produces a thinner, less flavorful broth. The 80/20 blend renders enough fat to build a rich base during the slow cook. Drain off excess fat after browning.

Tomato paste — two tablespoons stirred in with the browned beef deepens the tomato flavor significantly. It caramelizes slightly in the hot pan and adds a savory, umami backbone that crushed tomatoes alone can’t deliver.

Crushed tomatoes + marinara sauce — the combination gives the broth both body and pre-seasoned depth. Using all crushed tomatoes produces a thinner, plainer base. The marinara adds sweetness, herbs, and complexity without extra work.

Lasagna noodles, broken — regular dried lasagna noodles work perfectly. Break each noodle into 3-4 rough pieces so you get pasta in every spoonful. Add them in the last 30 minutes of cooking — no earlier.

Ricotta — whole milk ricotta is creamier and less grainy than part-skim. Mix it with mozzarella and Parmesan before serving and add it as a dollop on top of each bowl.

Italian seasoning + dried basil + oregano — layering both the blend and the individual herbs builds more complexity. Italian seasoning contains additional spices like thyme and marjoram that round out the flavor.

How to Make Crock Pot Lasagna Soup

1. Heat a large skillet over medium-high heat. Add ground beef and cook, breaking it up, until browned — about 6-7 minutes. Drain excess fat.
2. Add diced onion to the skillet. Cook for 3 minutes until softened.
3. Add minced garlic and tomato paste. Stir and cook for 1 minute.
4. Transfer the beef mixture to the slow cooker.
5. Add crushed tomatoes, marinara sauce, beef broth, basil, oregano, Italian seasoning, salt, pepper, and red pepper flakes. Stir to combine.
6. Cover and cook on LOW for 6-7 hours or HIGH for 3-4 hours.
7. About 30 minutes before serving, stir in the broken lasagna noodles.
8. Cover and cook on HIGH for 25-30 minutes until noodles are tender.
9. While noodles cook, mix ricotta, mozzarella, and Parmesan in a small bowl.
10. Ladle soup into bowls. Add a generous spoonful of the cheese mixture to each bowl.
11. Garnish with fresh basil and serve immediately.

Crock Pot Lasagna Soup Variations

Crock Pot White Lasagna Soup

Replace ground beef with shredded rotisserie chicken and swap the crushed tomatoes and marinara for 2 cups of heavy cream and 2 cups of chicken broth. Add 1/2 cup of cream cheese for extra body. The result is a rich, creamy white version with Italian herbs and tender chicken.

Vegetarian Crock Pot Lasagna Soup

Skip the ground beef and add 2 cups of diced zucchini, 1 cup of diced bell pepper, and 1 can of cannellini beans. Use vegetable broth in place of beef broth. The beans add protein and the extra vegetables keep the soup hearty and filling.

Spicy Crock Pot Lasagna Soup

Use hot Italian sausage instead of ground beef and double the red pepper flakes. Add a tablespoon of calabrian chili paste with the tomato paste. The heat builds slowly over the long cook time and balances well against the creamy ricotta topping.

Crock Pot Lasagna Soup With Italian Sausage

Swap ground beef for 1 lb of mild Italian sausage, removed from casings. The sausage adds fennel and garlic notes that make the soup taste even more like traditional lasagna. No extra seasoning needed — the sausage does the work.

Tips for the Best Crock Pot Lasagna Soup

• I always brown the beef before adding it to the slow cooker. Raw beef in a slow cooker produces gray, grainy meat and a flat-tasting broth. The browning step takes 10 minutes and makes a major difference.
• Add pasta in the last 30 minutes only. Lasagna noodles sitting in broth for 6 hours turn to mush and absorb all the liquid.
• Don’t skip the tomato paste. Two tablespoons cooked with the beef before it goes into the slow cooker deepens the entire broth.
• Mix the cheese topping separately and add it bowl by bowl. Stirring it directly into the pot makes the broth grainy and the cheese clumps.
• Taste and adjust salt at the end. Marinara sauce varies significantly in sodium between brands — always season to taste before serving.
• Leftovers thicken as the pasta absorbs broth overnight. Add a cup of beef broth when reheating and stir before serving.

Make Ahead & Storage

This crock pot lasagna soup keeps in the fridge for up to 4 days. Store it without the cheese topping — add fresh ricotta mix when reheating each serving. The pasta will absorb broth overnight so always add a splash of beef broth when reheating.

To freeze, cook the soup without the pasta. Cool completely, pour into freezer bags, and freeze for up to 3 months. Thaw overnight in the fridge, reheat on the stovetop over medium heat, and cook the broken lasagna noodles directly in the reheated soup for 25 minutes before serving.

Common Questions

Can I use no-boil lasagna noodles in crock pot lasagna soup?

Yes. No-boil noodles work well and cook slightly faster — add them 20 minutes before serving instead of 30. They absorb a bit more broth than regular noodles, so have extra beef broth ready to thin the soup if needed.

Can I make crock pot lasagna soup on the stovetop?

Yes. Brown the beef in a large pot, add all ingredients except pasta, and simmer on low for 45 minutes. Add broken noodles in the last 15 minutes and cook until tender. The flavor won’t be as deep as the slow cooker version but it’s ready in under an hour.

How do I keep the noodles from getting soggy?

Add the broken lasagna noodles in the last 30 minutes of cooking only. If you’re making a large batch for meal prep, cook the pasta separately and add it to individual bowls at serving time to keep it from continuing to absorb broth.

Can I use Italian sausage instead of ground beef?

Yes. Mild or hot Italian sausage, removed from casings, is a direct substitute. It adds fennel and spice notes that make the soup taste even more like traditional lasagna. The fat content is similar so no other adjustments are needed.
