Warm up with this hearty crockpot lasagna soup featuring rich tomato broth, tender lasagna sheets, and fresh baby spinach. Each serving is topped with creamy ricotta cheese and grated Parmesan for added flavor.
Prep all ingredients.
In a large nonstick skillet over medium-high heat, cook the ground beef, onion, garlic, 1/2 tsp salt, and 1/2 tsp black pepper until the beef is no longer pink and onions are softened (about 8 minutes). Transfer to a 6-quart slow cooker.
Stir in broth, marinara sauce, diced tomatoes, tomato paste, crushed red pepper, remaining 1 tsp salt, and remaining 1/4 tsp black pepper.
Cook on LOW for 3 1/2 to 4 hours or on HIGH for 2 hours until the soup is slightly thickened.
Add lasagna noodles to the crockpot; ensure they're submerged in liquid. Cover and cook on HIGH for about 30 minutes until pasta is al dente.
Mix in spinach during the last 5 minutes of cooking.
Serve with a dollop of ricotta cheese and sprinkle Parmesan cheese on top. Garnish with extra crushed red pepper.
