Instructions:

Prepare the Meat Mixture:

Cook the Beef and Onion: Heat a medium-sized non-stick skillet over medium-high heat. Add ground beef and diced onion.
Season and Brown: Sprinkle in salt, pepper, garlic powder, and dried oregano. Cook until the beef is browned and onions are translucent. Ensure the meat is fully cooked. Leave a few tablespoons of juices in the skillet to keep the mixture moist for added flavor.

Prepare the Slow Cooker:

Grease the Slow Cooker: Spray the inside of your slow cooker with non-stick spray to prevent sticking and make cleanup easier.

Layer the Ingredients:

First Layer: Pour half of the marinara sauce into the bottom of the slow cooker, spreading evenly.
Second Layer: Arrange half of the frozen ravioli over the marinara sauce, covering it completely.
Third Layer: Spread all of the cooked ground beef and onion mixture over the ravioli.
Fourth Layer: Add the remaining ravioli on top of the beef mixture, covering it evenly.
Fifth Layer: Pour the remaining marinara sauce over the ravioli, spreading it evenly.
Sixth Layer: Sprinkle shredded mozzarella cheese over the sauce, covering the entire top layer.

Cooking:

Set the Slow Cooker: Cover the slow cooker with the lid and set to cook on LOW for 4 hours. The slow cooking allows flavors to meld, creating a rich, hearty lasagna.

Serving:

Check for Doneness: After 4 hours, ensure the ravioli is tender and the cheese is fully melted and bubbly.
Rest: Turn off the slow cooker and let the lasagna rest for about 10 minutes. This helps set the layers for easier serving.

Serving Suggestions:

Garlic Bread: Serve with warm garlic bread to soak up the marinara sauce and add an extra layer of flavor.
Salad: A simple green salad with Italian dressing pairs perfectly, balancing the richness of the lasagna.
Fresh Herbs: Garnish with chopped fresh basil or parsley for a burst of color and fresh flavor.

Storage and Reheating Tips:

Refrigeration: Store leftovers in an airtight container in the refrigerator for up to 3 days.
Freezing: This lasagna freezes well. Cool completely, portion, and place in freezer-safe containers for up to 2 months. Thaw in the refrigerator overnight before reheating.
Reheating: Reheat in the microwave or on the stovetop over low heat until warmed through. If reheating a larger portion, you can warm it in the slow cooker on low until heated.

Cheese Lovers’ Lasagna: Mix additional cheeses like ricotta or provolone into the layers for extra cheesy goodness.
