This Healthy Slow Cooker Lasagna Soup is a comforting, nutritious twist on traditional lasagna, cooked slowly to meld rich flavors with wholesome ingredients like lean ground beef, whole wheat noodles, and fresh vegetables. Perfect for an easy, hearty meal that requires minimal hands-on time.

  • Total Time: 4 hours 45 minutes
  • Yield: 8 servings

Ingredients

Meat and Aromatics

  • 1 lb. 95% lean ground beef
  • 1 onion, diced
  • 6 garlic cloves, minced

Liquids and Sauces

  • 28 oz. canned crushed tomatoes (ideally San Marzano)
  • 16 oz. marinara sauce (no sugar added)
  • 3 cups chicken broth

Seasonings and Herbs

  • 2 tsp. Italian seasoning
  • Salt and pepper, to taste

Pasta and Vegetables

  • 10 whole wheat lasagna noodles (or regular)
  • 1 zucchini, chopped
  • 6 oz. fresh spinach

Cheese

  • 1/2 cup Parmesan cheese

Instructions

  1. Saute & Brown: Add the ground beef, diced onion, and minced garlic to a skillet. Brown the mixture over medium heat for 5-7 minutes, breaking up the meat as it cooks until the beef is fully cooked and the onions are softened. Season with salt and pepper to taste. Alternatively, use the saute feature on your slow cooker if available.
  2. Cook: Transfer the browned beef mixture to the slow cooker. Add the crushed tomatoes, marinara sauce, chicken broth, and Italian seasoning. Stir to combine all ingredients evenly. Cover and cook on low heat for 4 hours, allowing the flavors to develop; you may cook up to 8 hours if desired.
  3. Add Noodles and Vegetables: After the initial cooking time, open the slow cooker and add the whole wheat lasagna noodles broken into smaller pieces, chopped zucchini, and fresh spinach. Stir gently to incorporate. Cover and cook for an additional 25-30 minutes until the noodles are tender and the vegetables have softened.
  4. Add Cheese: Stir in the grated Parmesan cheese until melted and well combined. Taste and adjust seasoning with additional salt and pepper if needed. Serve warm, garnished with extra Parmesan or fresh herbs if desired.

Notes

  • Using 95% lean ground beef keeps the soup lower in fat while maintaining flavor.
  • For a vegetarian version, substitute ground beef with lentils or plant-based meat alternatives and use vegetable broth.
  • Whole wheat lasagna noodles add extra fiber and nutrients compared to regular pasta.
  • To save time, you can brown the beef directly in the slow cooker if it has a saute function.
  • The soup can be stored in the refrigerator for up to 4 days or frozen for up to 3 months.
  • Add fresh herbs like basil or oregano at the end for extra flavor.
