This 4-ingredient slow cooker ravioli is my go-to on those nights when work runs late, the kids are hungry, and I need dinner to basically cook itself. You literally dump completely frozen ravioli into the crock pot, add three everyday ingredients, and walk away. A few hours later you’ve got a cozy, cheesy pasta dinner that tastes like you fussed over it all afternoon. It’s very Midwest weeknight-friendly—comforting, hearty, and budget-conscious—without a pile of dirty dishes or a long ingredient list.
Serve this slow cooker ravioli straight from the crock pot with a simple green salad or steamed veggies to balance the richness. Garlic bread or a warm baguette is perfect for soaking up the extra sauce. If you like, sprinkle additional Parmesan and a little cracked black pepper over each bowl. A light red wine or sparkling water with lemon pairs nicely, and for a family-friendly touch, set out a small bowl of red pepper flakes so everyone can adjust the heat to their own taste.
4-Ingredient Slow Cooker RavioliServings: 4-6
Ingredients
1 (25–28 oz) bag frozen cheese ravioli (keep completely frozen)
1 (24 oz) jar marinara or pasta sauce
2 cups shredded mozzarella cheese, divided
1 teaspoon Italian seasoning (or dried basil and oregano blend)
Directions
Lightly spray the inside of your slow cooker with nonstick cooking spray to help prevent sticking and make cleanup easier.
Pour about 1 cup of the marinara sauce into the bottom of the slow cooker and spread it out so it fully covers the base.
Dump the completely frozen cheese ravioli in an even layer over the sauce in the bottom of the slow cooker. Do not thaw the ravioli first.
Sprinkle 1 1/2 cups of the shredded mozzarella evenly over the frozen ravioli.
Sprinkle the Italian seasoning over the cheese and ravioli for extra flavor.
Pour the remaining marinara sauce evenly over the top, making sure most of the ravioli are covered with sauce.
Cover the slow cooker with the lid and cook on LOW for 3–4 hours, or until the ravioli are tender and heated through and the sauce is bubbling around the edges. Avoid opening the lid during the first 2 hours so the heat stays consistent.
In the last 15–20 minutes of cooking, sprinkle the remaining 1/2 cup shredded mozzarella over the top, then cover again and let it melt into a gooey layer.
Once the cheese is melted and the ravioli are soft, turn the slow cooker to WARM. Gently scoop the ravioli into bowls, making sure to get plenty of sauce and cheese in each serving. Serve hot.
Variations & Tips
Swap the sauce: Use tomato basil, roasted garlic, or a chunky vegetable marinara for a slightly different flavor without adding extra steps. Add protein: Layer 1–1 1/2 cups of cooked and crumbled Italian sausage, ground beef, or rotisserie chicken over the frozen ravioli before adding the cheese for a heartier meal. Change the ravioli: Try frozen beef, spinach-ricotta, or mushroom ravioli instead of cheese. Extra cheesy: Stir in 1/2 cup grated Parmesan with the mozzarella for a sharper, more complex cheese flavor. Veggie boost: If you have a few extra minutes, scatter a handful of frozen spinach or peas over the ravioli before adding the cheese—no need to thaw them. Spice it up: Add a pinch of red pepper flakes with the Italian seasoning for a gentle kick. Make-ahead tip: You can assemble everything in the slow cooker insert the night before, cover, and refrigerate. In the morning, place the insert into the base and cook on LOW, adding about 30 extra minutes if starting cold. Leftovers reheat well in the microwave with a splash of extra sauce if needed to keep everything saucy and tender.
