Slow Cooker Lasagna Soup

Some recipes feel like a shortcut, and others feel like a little bit of magic. This Slow Cooker Lasagna Soup is both. It takes the familiar flavors of a classic lasagna dinner and turns them into a warm, comforting soup that simmers all day.

The broth is rich and tomato-based, the beef is hearty, and the noodles soak up all that slow cooked flavor. Finished with a spoonful of ricotta and melted cheese on top, it feels like something that could have easily shown up at a family table years ago.

It reminds me of the kind of meal that stretches dinner a little further, fills the house with good smells, and always seems to taste even better the next day.

How to Make Slow Cooker Lasagna Soup

Step 1: Brown the ground beef in a large skillet over medium-high heat until fully cooked. Drain off any excess grease.

Step 2: Transfer the cooked beef to a large slow cooker. Add the diced onion, red bell pepper, crushed tomatoes, and diced tomatoes.

Step 3: Stir in the minced garlic and Italian seasoning. Pour in the beef broth and gently mix everything together. Cover and cook on Low for 6 to 8 hours or on High for 3 to 4 hours.

Step 4: Remove the lid and break the lasagna noodles into bite-size pieces directly over the slow cooker. Stir them in, cover again, and cook on High for 30 to 45 minutes, until the noodles are tender.

Step 5: Ladle the soup into bowls and top with a dollop of ricotta, a sprinkle of mozzarella, and shredded Parmesan. Garnish with fresh basil if desired.
