Ingredients You’ll Need

In a black oval cooking pot, there are three visible layers: the bottom layer is a reddish sauce spread evenly across the base, the middle layer is made of crumbled brown meat scattered on top of the sauce, and the top layer consists of square pasta pieces with light cream color and ruffled edges loosely covering the meat. The pot sits on a white marbled surface, and a white bowl filled with shredded cheese is partially visible near the bottom left corner of the image photo taken with an iphone --ar 4:5 --v 7

Gathering these simple but essential ingredients is the first step towards creating something truly delicious. Each item plays a vital role, from the tender frozen ravioli that delivers that perfect bite, to the rich marinara sauce that brings vibrant color and depth, while the seasonings ensure every layer bursts with flavor.

25 oz. frozen ravioli: Using frozen ravioli, ideally five cheese, saves time and adds a lovely, cheesy texture that’s key for this recipe.
1 lb. ground beef: Provides hearty protein and a savory base that complements the pasta beautifully.
1 cup white onion, diced: Adds a subtle sweetness and aromatic depth when cooked with the beef.
1/2 tsp. salt: Enhances all the flavors without overpowering them.
1/4 tsp. pepper: Gives a gentle kick and balances the richness.
1/4 tsp. garlic powder: Infuses a mellow garlic essence, perfect for layering flavor.
1/2 tsp. dried leaf oregano: Brings an earthy, slightly minty herbaceous note essential to Italian dishes.
24 oz. marinara sauce: I recommend a quality brand like Rao’s which offers fresh tomato brightness and complexity.
8 oz. shredded mozzarella cheese: About 2 cups for a gooey, melty topping that binds the lasagna together.

How to Make Slow Cooker Ravioli Lasagna Recipe

Step 1: Brown the Beef and Sauté Onions

Start by heating a medium non-stick skillet over medium-high heat; this is where your savory foundation begins. Add the ground beef along with the diced onions, salt, pepper, garlic powder, and oregano. Cook everything until the beef is browned and the onions are soft – this mixture will be packed with flavor as it simmers and caramelizes. Keep a few tablespoons of the beef’s natural juices; these add moisture and richness later in the slow cooker.

Step 2: Prepare the Slow Cooker Base

Spray your slow cooker with a non-stick spray to ensure nothing sticks during the slow cooking process. Pour half of your marinara sauce evenly across the bottom – this tomato layer will keep the ravioli from sticking and infuse them with tangy sweetness.

Step 3: Add the First Layer of Ravioli

Next, spoon half of the frozen ravioli on top of the sauce in an even layer. Remember, do not thaw your ravioli before adding them; the frozen state helps maintain the perfect texture during cooking.

Step 4: Layer the Beef Mixture

Spread all the cooked ground beef and onion mixture evenly over your ravioli layer. The blend of herbs, spices, and juices from the beef adds a wonderful depth of flavor nestled right in the middle of the dish.

Step 5: Add the Second Layer of Ravioli and Sauce

Cover the beef with the remaining ravioli and pour the remaining marinara sauce over the top. This layering ensures every bite has a harmonious mix of pasta, meat, and sauce.

Step 6: Top with Cheese and Cook

Sprinkle your shredded mozzarella cheese over the whole slow cooker creation. Placing the lid on, set the cooker to low and let it work its magic for 4 hours. This slow cooking melds the layers together perfectly, resulting in a lasagna that’s creamy, tender, and bursting with flavor.

On the left side of the bowl, there is a fresh salad made of dark green and purple leafy greens mixed with small round yellow and red cherry tomatoes. At the top right edge of the bowl, two thick slices of a white, soft bread are placed. The bowl sits on a white marbled surface, and a gray cloth is visible in the background.

Make Ahead and Storage

Storing Leftovers

Place leftover lasagna in an airtight container and refrigerate for up to 3 days. The flavors actually deepen overnight, making for an even tastier next-day meal.

Freezing

This recipe freezes well if you want to keep portions on hand. Transfer cooled portions into freezer-safe containers or bags for up to 2 months. Just be sure to thaw overnight in the fridge before reheating.

Reheating

For best results, reheat leftovers gently in the oven at 350°F until warmed through or microwave individual portions covered loosely to maintain moisture and prevent drying out.

FAQs

Can I use a different type of ravioli?

Absolutely! While five cheese ravioli is ideal for a rich, creamy texture, feel free to experiment with your favorite ravioli fillings such as spinach, mushroom, or meat to personalize this recipe.

No need to thaw the ravioli beforehand. Using frozen ravioli helps maintain its shape and texture after cooking, resulting in a perfect bite every time.

What if I don’t have dried leaf oregano?

You can substitute with Italian seasoning or fresh oregano, adjusting the quantity to suit your taste. The herb adds that classic Italian flair that complements the marinara and cheese so well.

Cooking the Slow Cooker Ravioli Lasagna Recipe on high usually takes about 2 to 2.5 hours, but keep an eye on it to make sure it doesn’t overcook or dry out.
