How to Make Slow Cooker Lasagna Soup

Prepare the crockpot: Lightly grease the inside of your 6-quart slow cooker with a little olive oil to prevent sticking and ensure easy cleanup.
Brown the meat: In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Add the ground beef and Italian sausage. Cook for 6–8 minutes until the meat is thoroughly browned, breaking it into small crumbles. Drain any excess grease.
Cook the aromatics: Stir in the diced onion and cook for 3–4 minutes until softened. Then, add the minced garlic and cook for an additional 30 seconds until fragrant.
Add the meat: Transfer the browned meat, onion, and garlic mixture to the bottom of the crockpot, laying a flavorful foundation for your soup.
Add the tomato ingredients: Pour in the crushed tomatoes, tomato sauce, and tomato paste, combining all the flavors beautifully.
Add the broth and seasonings: Pour in 4 cups of low-sodium beef broth. Add the Italian seasoning, dried basil, dried oregano, salt, black pepper, and red pepper flakes. Stir until well combined for a delightful aromatic base.
Slow cook: Cover and choose LOW for 5–6 hours or HIGH for 2½–3½ hours. Your soup is cooking away, blending all those rich flavors together!
Add the lasagna noodles: About 30–40 minutes before serving, switch the slow cooker to HIGH. Stir the uncooked broken lasagna noodles into the soup, ensuring they are submerged in the broth.
Cook the pasta: Cover and cook on HIGH for 25–35 minutes, stirring once or twice, until the noodles are tender but not mushy. If the soup gets too thick, add up to 1/2 cup of hot water for a perfect consistency.
Prepare the cheese topping: In a small bowl, blend the whole-milk ricotta cheese with the grated Parmesan cheese until creamy and smooth; this will create a delightful topping.
Check the soup: Gently stir and verify that the lasagna noodles are thoroughly cooked. Taste and adjust the salt and pepper to your liking.
Add the cheese: Spoon dollops of the ricotta-Parmesan mixture over the soup’s surface, and sprinkle the shredded mozzarella around for that classic cheesy goodness.
Melt the cheese: Cover and cook on LOW for an additional 5–10 minutes until the mozzarella melts and the ricotta warms through, making it even more comforting.
Garnish and serve: Sprinkle freshly chopped basil over the top for a burst of flavor and color. Serve your delicious lasagna soup warm right from the crockpot.

Optional: Serve with crusty bread for an even heartier meal.

Slow Cooker Lasagna Soup Recipe FAQs
