1. Prepare your crockpot by adding a thin layer of pasta sauce at the bottom to prevent sticking.

2. Layer the ingredients in the crockpot in the following order: ravioli, browned ground beef, shredded Parmesan cheese, mozzarella cheese, and pasta sauce. Repeat the layers until all ingredients are used, finishing with a layer of sauce and cheese on top.

3. Set the crockpot to cook on high for 2 hours or low for 4 hours. This allows the ravioli to cook through and the cheese to melt and become bubbly.

4. Once cooked, serve hot and enjoy the delightful flavors of this easy-to-make Crock pot Ravioli Lasagna.
