Preparation
- Grease a 6-quart or larger slow cooker with cooking spray.
- Spread about 1/2 cup of marinara sauce on the bottom of the slow cooker; optionally, stir in cooked ground beef or Italian sausage.
- Arrange half of the frozen ravioli in a single layer over the sauce.
- Dot half of the ricotta cheese over the ravioli.
- Sprinkle 1 cup of mozzarella and ¼ cup of Parmesan cheese over the ricotta.
- Spoon about 1 cup of marinara sauce over the cheeses, adding more cooked meat if desired.
- Repeat layers with the remaining ravioli, ricotta, mozzarella, and Parmesan cheese.
- Pour the remaining marinara sauce over the top layer and gently add 1 cup of water around the edges.
- Cook on LOW for 3-4 hours or on HIGH for 2-3 hours, until ravioli are tender and cheese is bubbly.
- Let the lasagna rest for 10-15 minutes before serving, and garnish with fresh basil if desired.
Notes
For an even richer flavor, consider using a good quality, slow-simmered marinara sauce. If you prefer a vegetarian version, simply omit the ground beef or Italian sausage. The resting time after cooking is crucial for allowing the lasagna to set, making it easier to serve.
