Crockpot Lasagna Soup

Ingredients

  • 1.5 lb. lean ground beef (I used 96/4)
  • 1 medium onion (200g), diced
  • 24 oz. can marinara sauce (I used Rao’s)
  • 1/3 cup tomato paste
  • 3 cloves garlic, minced
  • 1 tablespoon Italian seasoning
  • 1 teaspoon salt, more as needed
  • 1/4 teaspoon red pepper flakes (optional)
  • 5 cups beef broth
  • 8–9 lasagna noodles, broken into small pieces
  • 2 cups fresh spinach (optional)
  • 1 cup part-skim ricotta cheese
  • 1 cup shredded mozzarella cheese
  • Grated Parmesan cheese (optional, but highly recommended) for serving

Brown the Beef and Onion

In a large skillet over medium heat, brown the ground beef with the diced onion.

Cook until the beef is fully browned and the onion has softened.

Drain away any excess grease.

Transfer to Slow Cooker

Place the browned beef and onion mixture into the Crock Pot.

Add the marinara sauce, tomato paste, Italian seasoning, salt, and red pepper flakes.

Stir well to combine.

Add Liquids and Garlic

Pour in the beef broth and stir in the minced garlic. Mix thoroughly to form a consistent soup base.

Slow Cook the Soup

Cover the slow cooker and cook on low for 4 to 5 hours or on high for 2 to 3 hours.

If necessary, you can extend the cooking time on low without any issues.

Break and Add Noodles

Remove the lid and break the lasagna noodles into bite-size pieces over the slow cooker.

Stir them into the soup, cover, and cook on high for an additional 30 minutes, or until the noodles are tender.

Stir in Fresh Spinach

Just before serving, stir fresh spinach into the soup until it wilts.

Alternatively, you can add the spinach directly to individual bowls if you prefer.

Finish with Cheese

Serve the soup by topping each bowl with a generous spoonful of ricotta cheese and sprinkling shredded mozzarella cheese on top.

If desired, garnish with grated Parmesan cheese. Enjoy!
