This slow cooker 3-ingredient cheesy ravioli is exactly the kind of recipe my church friends pass around after potlucks. One of the ladies brought it to a Sunday potluck, set the slow cooker on the counter, lifted the lid, and everyone immediately lined up because it smelled like a cozy Italian restaurant. It’s literally just three ingredients layered together, then you forget about it for a few hours. The ravioli turns tender, the sauce bubbles up around the edges, and the mozzarella melts into this gooey, browned blanket of cheese. It’s perfect for busy weeknights, game days, or anytime you want comfort food with almost zero effort.
Serve big spoonfuls of the cheesy ravioli straight from the slow cooker with a simple green salad and some garlic bread or buttered rolls to soak up the extra sauce. A side of steamed green beans or roasted vegetables balances out the richness. If you’re feeding a crowd, set the slow cooker on warm and let people help themselves, keeping grated Parmesan, red pepper flakes, and a little bowl of chopped fresh basil or parsley on the side for topping.
Slow Cooker 3-Ingredient Cheesy RavioliServings: 6
Ingredients
1 (24–28 ounce) jar marinara or spaghetti sauce
1 (25–27 ounce) bag frozen cheese ravioli
3 cups shredded mozzarella cheese
Directions
Spray the inside of a 5- to 6-quart slow cooker lightly with nonstick cooking spray to help with cleanup.
Pour about 1/2 cup of the marinara or spaghetti sauce into the bottom of the slow cooker and spread it around to lightly coat the bottom. This keeps the ravioli from sticking.
Add a single, even layer of frozen cheese ravioli over the sauce. It’s fine if a few overlap slightly, but try to keep them mostly in one layer.
Spoon more sauce over the ravioli, just enough to cover them, then sprinkle a generous handful of shredded mozzarella cheese over the top.
Repeat the layers—ravioli, sauce, mozzarella—until you’ve used all the ravioli. Finish with a final layer of sauce and then the remaining mozzarella cheese on top, making sure the top is well covered so it melts into a gooey, cheesy blanket.
Cover the slow cooker with the lid and cook on LOW for 3 1/2 to 4 hours, or until the ravioli are tender and cooked through and the cheese on top is fully melted and starting to brown around the edges. Avoid lifting the lid during cooking so the heat stays in.
Once cooked, switch the slow cooker to WARM if you’re serving at a potluck or over a longer period. Let the ravioli sit for about 10 minutes with the lid slightly cracked before serving so it can set up a bit and is easier to scoop.
Spoon the cheesy ravioli straight from the slow cooker into bowls or onto plates, making sure everyone gets some of the saucy bottom and the gooey, browned cheese from the top.
Variations & Tips
Use this as a base and tweak it to fit your family. For extra cheesiness, swap part of the mozzarella for an Italian blend or add a layer of sliced provolone in the middle. If you like a little kick, choose a spicy marinara or stir some red pepper flakes into the sauce before layering. You can also use different flavors of frozen ravioli—spinach and cheese or four-cheese both work well—just keep them cheese-based so you’re still at three ingredients. For a heartier version, use a meat sauce instead of plain marinara. To keep things lighter, choose a lower-sodium sauce and part-skim mozzarella. If your slow cooker tends to run hot, check the ravioli at about 3 hours so the edges don’t overcook; you want the cheese browned on top but not burnt. Leftovers reheat nicely in the microwave the next day, and you can add a splash of extra sauce if they seem a little dry.
