This Slow Cooker Ravioli Lasagna is an easy and hearty twist on classic lasagna, and is great for busy weeknights. With layers of cheese-stuffed ravioli, punchy marinara and well-seasoned ground beef, this dish packs all the comforting goodness of lasagna without a pot of boiling noodles or complicated layering. It’s an honest-to-goodness “set it and forget it” meal that comes out so wonderfully rich and satisfying.

Using frozen ravioli as the bottom layer makes it much easier to prepare a casserole layer, and the seasoned ground beef intermixed with onions brings a delicious richness, especially when combined with marinara sauce and globs of mozzarella. The slow cooker lets all the flavors meld beautifully over 4 hours, resulting in a dish that’s melt-in-your-mouth tender, cheesy and luscious with flavor. Allowing the lasagna to rest for a few minutes before serving enables the layers to retain their structure.

Serve with a side of garden salad and garlic bread for a complete Italian-inspired comfort dish the whole family will love. This is a simple, tasty recipe that will quickly become a go-to in your meal rotation!

Key Ingredients:

Frozen Ravioli: Five-cheese ravioli brings a rich, cheesy element to this lasagna. Other flavors could also work well, such as spinach or meat-stuffed ravioli, for an extra twist.

Ground Beef: You can use half or all of the ground beef for mild Italian sauce for some extra flavor.

Marinara Sauce: Rao’s makes a high-quality marinara sauce, which adds depth of flavor to the dish. Store-bought sauce also does the trick if you like.

Shredded Mozzarella: Mozzarella makes for a perfect cheesy, gooey topping. (You can add some Parmesan or provolone for even more flavor, if you like.)

Seasonings: Garlic powder, oregano, salt, and pepper season the beef mixture perfectly, making this easy lasagna taste like classic Italian.

Instructions:

Prepare the Meat Mixture:

Hello, my name is Pia and I have a new mom life hack for you! Ground beef and diced onion.

Season and brown: Add salt, pepper, garlic powder and dried oregano. Cook until the beef has browned and the onions are translucent. Make sure the meat is completely cooked. Leave a few tablespoons of juices in the skillet to moisten the mixture for flavor.

Prepare the Slow Cooker:

Fry for 7 minutes until browned, then fry for another 5 minutes in some oil.

Layer the Ingredients:

Base Layer: Spread half of the marinara sauce across the bottom of the slow cooker.

Second Layer: Place half of frozen ravioli on top of marinara sauce, covering it completely.

Third Layer: Spread all of the cooked ground beef and onion mixture across the top of the ravioli.

Fourth Layer: Place remaining ravioli over beef mixture, making sure to use enough to cover.

Fifth Layer: Pour remaining marinara sauce on the ravioli and spread evenly.

Sixth Layer: Spread shredded mozzarella cheese over the sauce, covering the very top layer.

Cooking:

Slow cooker is set on a LOW 4 hours. The low-and-slow cooking gives flavors a chance to meld, making for a rich, hearty lasagna.

Serving:

Check for Doneness: Once 4 hours has passed, the ravioli should be tender and the cheese should be melted and bubbly.

Rest: Switch off the slow cooker and allow the lasagna to rest for about 10 minutes. This makes for easy layered serving.

Serving Suggestions:

Garlic Bread: Offer garlic bread warmed on the side for dipping into the marinara sauce and for an extra boost of flavor.

Salad: Just a simple green salad with Italian dressing is perfect, balancing out the richness of the lasagna.

Fresh Herbs: Top it off with chopped fresh basil or parsley for a shot of color and fresh flavor.

Storage and Reheating Tips:

Refrigerate: Refrigerate any leftovers in an airtight container for up to 3 days.

Freezing: This lasagna is freezer friendly. Let cool completely, divide into portions, and store in freezer-safe containers for up to 2 months. Defrost in refrigerator overnight, then reheat.

To reheat: Reheat in the microwave or stovetop over low heat, until warmed through. If you will be reheating a larger amount of this, it can be warmed up on low in the slow cooker until warmed through.

Variations:

Vegetarian Ravioli Lasagna: Swap the ground beef for chopped mushrooms with chopped zucchini or spinach for a veggie-filled recipe.

Cheese Lovers’ Lasagna: Add extra cheeses to the layers (ricotta, provolone, etc.) for more cheesy goodness.

Spicy Kick: Sprinkle some red-pepper flakes into the marinara sauce for a little heat.

Italian Sausage Option: Substitute mild Italian sausage for the ground beef for a spicy, more flavorful filling.

Herbed Ricotta Layer: Mix ricotta with Italian seasoning and add a layer of it between the ravioli layers for a creamy surprise.
