Instructions
Lightly coat the inside of a 5- to 6-quart slow cooker with nonstick cooking spray.
Spread about ½ cup of marinara sauce over the bottom of the slow cooker to prevent sticking.
Add a single layer of frozen cheese ravioli.
Spoon additional marinara sauce over the ravioli until covered.
Sprinkle a generous layer of shredded mozzarella over the sauce.
Continue layering ravioli, sauce, and mozzarella until all ingredients have been used.
Finish with a final layer of sauce followed by the remaining mozzarella cheese.
Cover and cook on LOW for 3½ to 4 hours, or until the ravioli are tender and the cheese is fully melted and lightly browned around the edges.
Once finished, switch the slow cooker to the WARM setting if serving over an extended period.
Allow the ravioli to rest for about 10 minutes before serving to help the layers set.
Now that the ravioli is perfectly cooked, a few simple serving ideas and easy variations can make this comforting meal even more versatile.
