Ingredients and Preparation

Frozen Ravioli – The real MVP of this dish. These little pasta pillows are filled with cheese, so they do double duty as both the noodles and the creamy layer. Choose a five-cheese variety for a rich texture, or try spinach ravioli for added greens.

Ground Beef – Adds savory depth and satisfying heartiness. You can use lean ground beef, sausage, or even turkey. For vegetarians, swap in soy crumbles or chopped mushrooms.

Marinara Sauce – A flavorful base that brings the dish together. A quality jarred sauce like Rao’s makes a huge difference in taste. Alfredo or salsa can also be used for fun variations.

Mozzarella Cheese – The gooey, melty crown of the lasagna. Shredded whole milk mozzarella gives the best melt. Add a sprinkle of parmesan for extra flavor.

Onion and Seasonings – Chopped onions, garlic powder, oregano, salt, and pepper create a fragrant base that flavors the entire dish. These bring out the richness of the meat and balance the acidity of the sauce.

Optional Add-ins – Spinach, zucchini, or frozen meatballs can stretch or personalize the dish. Feel free to make it your own.

Step-by-Step Instructions

Step 1: Brown one pound of ground beef in a skillet over medium-high heat, adding chopped onion, garlic powder, oregano, salt, and pepper. Cook until the meat is no longer pink, stirring occasionally to break it up into small pieces.

Step 2: Once the meat is cooked, leave about two to three tablespoons of the liquid in the pan—this helps keep the dish moist and flavorful. Don’t drain it completely.

Step 3: Lightly spray the bottom and sides of your slow cooker with non-stick cooking spray to prevent sticking.

Step 4: Pour half of the marinara sauce into the bottom of the slow cooker, spreading it evenly.

Step 5: Place half of the frozen ravioli in a single layer over the sauce. It’s okay if they overlap slightly.

Step 6: Spoon all of the seasoned beef mixture evenly over the ravioli layer, making sure it spreads across the dish.

Step 7: Add the remaining ravioli on top of the meat layer, again arranging in a mostly single layer.

Step 8: Pour the rest of the marinara sauce over the top and spread it evenly to cover the ravioli.

Step 9: Sprinkle shredded mozzarella cheese across the top layer, covering the sauce completely.

Step 10: Cover the slow cooker with the lid and cook on LOW for four hours. When the cheese is bubbly and the ravioli are tender, it’s ready to serve.

Beginner Tips and Notes

If your ravioli looks too dry halfway through cooking, add a few tablespoons of water or extra sauce around the edges.

Don’t thaw the ravioli beforehand—keeping them frozen helps them cook evenly and hold their shape.

Avoid opening the slow cooker lid too often, as this releases heat and may lengthen cooking time.

Want to prep ahead? Brown the meat mixture the night before and store it in the fridge, ready to assemble the next day.

Don’t have a slow cooker? You can layer the ingredients in a casserole dish and bake at 375°F for 45 minutes covered, then uncover for the last 10 minutes.

Serving Suggestions

Pair this slow cooker ravioli lasagna with a crisp Caesar salad or a basic garden salad with ranch dressing for balance.

Add garlic bread or French bread on the side to soak up any extra sauce.

Serve with roasted vegetables like zucchini, bell peppers, or broccoli for added nutrition.

Leftovers keep well in an airtight container in the fridge for up to three days. Reheat in the microwave or oven until warm. You can also freeze individual portions for up to a month.
