An easy, cheesy, comforting meal made in the slow cooker with layers of tender ravioli, savory tomato sauce, and lots of gooey cheese. Perfect for busy nights or cozy weekends!
For extra cheesiness, stir additional shredded cheese directly into the sauce before layering. Add cooked Italian sausage or ground beef between layers for a heartier version. Toss in spinach or sautéed mushrooms for a veggie-packed twist. Store leftovers in an airtight container in the refrigerator for up to 3 days, or freeze for up to 2 months. Reheat gently and top with fresh cheese before serving.
