• Step 1: Spray the inside of your crockpot with nonstick cooking spray. Spread 1/2 cup of marinara sauce in the bottom of the crockpot.
• Step 2: Arrange a single layer of frozen ravioli on top of the sauce. Top with 1/2 cup of ricotta cheese, 1/2 cup of mozzarella cheese, and 2 tablespoons of Parmesan cheese. Sprinkle with 1/2 teaspoon of dried basil and 1/2 teaspoon of dried oregano.
• Step 3: Repeat the layers of ravioli, ricotta, mozzarella, Parmesan, basil, and oregano until all ingredients are used up, ending with a layer of ravioli.
• Step 4: Pour the remaining marinara sauce and tomato sauce over the top. Cover and cook on low for 4-6 hours, or until the ravioli are tender and the cheese is melted and bubbly.
