Slow Cooker Vegetable Lasagna

You can make homemade slow cooker vegetable lasagna that requires only a few minutes of prep work, but tastes like it took all day to create.

Slow Cooker Vegetable Lasagna


  • Non-stick cooking spray
  • 2 cans (8 oz. each) tomato sauce with basil, garlic and oregano
  • 1 can (14.5 oz.) diced tomatoes with basil, garlic and oregano, undrained
  • 1 container (8 oz.) part-skim ricotta cheese
  • 1/4 teaspoon salt
  • 1/4 teaspoon ground black pepper
  • 6 dry lasagna noodles, uncooked
  • 1 pkg (8 oz.) fresh sliced mushrooms, optional (I don’t add these to mine!) 
  • 1 pkg (6 oz.) baby spinach leaves
  • 2 cups shredded part-skim mozzarella cheese, divided

tomato sauce


  1. Spray the inside of a 4-quart slow cooker with cooking spray. Stir together tomato sauce and undrained tomatoes in a medium-sized bowl and set the mixture aside. Combine ricotta, salt and pepper in small bowl and set aside.
  2. Spread 3/4 cup tomato mixture over the bottom of the slow cooker. Layer 3 lasagna noodles over the tomato mixture, breaking the noodles to fit. Top with 3/4 cup tomato mixture, mushrooms, spinach, ricotta cheese mixture and 1 cup mozzarella cheese. Top with 3/4 cup tomato mixture and 3 remaining lasagna noodles. Spoon the rest of the tomato mixture over the noodles.
  3. Cover and cook on low 5 to 6 hours or until noodles are tender. Sprinkle with the remaining 1 cup mozzarella cheese. Cover and let the lasagna stand for 5 minutes or until the cheese is completely melted.


  1. Don’t worry if your slow cooker is almost filled to the top when you first add the ingredients. The ingredients will cook down after a few hours in the slow cooker. However, do not fill your slow cooker more than 3/4 of the way full.
  2. Try not to open the lid of your slow cooker unless it is absolutely necessary. Opening the lid causes the slow cooker to lose steam and increases the cooking time.
  3. The best thing about lasagna is that it’s extremely customizable. Add your favorite vegetables to make this lasagna even more nutritious. You can also brown ground beef, sausage, turkey or chicken and add it to each layer in the slow cooker. When making lasagna, the possibilities are endless!
