Easy Slow Cooker Lasagna layered with noodles, homemade meat sauce and three kinds of cheese! This lasagna takes only 15 minutes of prep time and couldn't be any easier to make!
Spray the slow cooker insert with nonstick cooking spray.
Make the meat sauce: Add olive oil to a large skillet or pot. Add in sausage and ground beef and cook until golden brown and no longer pink. Add in the onion and garlic and saute for an additional 2 minutes or so to develop some color. Stir in tomato sauce, water and Italian seasoning. Season with salt and pepper to taste.
Assemble: Layer 1/4 of the meat sauce onto the bottom of the slow cooker. Top with 3 lasagna noodles breaking them up so they fit. It is okay if they overlap. Spread 1/3 of the ricotta on top of the noodles then sprinkle with 1/4 cup parmesan and 1/2 cup mozzarella cheese. Repeat with two more layers or until you run out of ingredients. (Make sure to reserve 1/2 cup of mozzarella for topping after cooking). The last layer should be tomato sauce.
Cook: For 4 hours on low heat or until noodles are tender. Sprinkle the remaining 1/2 cup of mozzarella on top and cover to melt the cheese. This should take only a couple of minutes.
Serve: I let the lasagna rest for 15-30 minutes to make slicing easier. Serve with fresh basil for garnish, if desired.
