Easy Slow Cooker Ravioli Lasagna with Ground Beef Tips, FAQ & printable recipe

Tips for success

For the absolute best results, avoid opening the slow cooker lid during the first two hours of cooking. Each time the lid is lifted, a significant amount of steam and heat escapes, which can add fifteen to twenty minutes to the total cooking time and disrupt the delicate steaming process required for the frozen pasta.

If you notice excess moisture building up on the underside of the lid toward the end of the cooking cycle, place a clean paper towel under the lid for the final thirty minutes to absorb the condensation.

To elevate the flavor profile even further, consider layering in additional elements between the pasta and meat. Sautéed sliced mushrooms, baby spinach, or caramelized onions can be scattered over the ground beef layer to introduce fresh textures and earthy notes.

If a crispy cheese top is desired, carefully transfer the oven-safe ceramic slow cooker insert to a preheated conventional oven and broil the top for two to three minutes just before serving, watching closely to prevent burning.

Variations

• Spicy Italian Sausage: Replace the ground beef with sweet or spicy Italian sausage to add a robust, herbaceous flavor to the lasagna layers.
• Vegetarian Spinach: Omit the ground beef and use spinach-and-cheese ravioli, adding a layer of sautéed baby spinach and sliced mushrooms between the pasta layers.

Storage and make-ahead

Fridge

Store leftovers in an airtight container in the refrigerator for up to 3 to 4 days, cooling them for no more than 2 hours beforehand.

Freezer

Freeze in airtight, freezer-safe containers for up to 3 months. Thaw in the refrigerator overnight before reheating.

Reheat

Reheat individual portions in the microwave for 1 to 2 minutes, or bake covered in a 350°F (175°C) oven for 15 to 20 minutes.

Allow any leftovers to cool completely at room temperature for no more than two hours to ensure food safety. Transfer the cooled ravioli lasagna to an airtight container and store it in the refrigerator. Properly stored, the lasagna will remain fresh and delicious for up to three to four days. The flavors often deepen and improve after a day in the fridge, making the leftovers highly anticipated.

This dish is highly adaptable for advance preparation. The ground beef can be browned, seasoned, and stored in the refrigerator up to two days in advance. You can also assemble the entire lasagna directly in the slow cooker insert the night before, cover it tightly with plastic wrap, and store it in the refrigerator overnight.

In the morning, simply remove the plastic wrap, place the insert into the heating base, and cook as directed, adding about thirty minutes to the cooking time.

Serving ideas

Serve this hearty lasagna warm, scooping deep portions with a large serving spoon to capture all the beautiful layers and the dramatic mozzarella cheese pull.

Accompany the dish with a crisp, green garden salad dressed with a bright vinaigrette to cut through the richness of the cheese and pasta. A side of warm garlic bread or crusty Italian bread is also highly recommended, perfect for scooping up any delicious marinara sauce left on the plate.

For a complete Italian-themed dinner experience, pair the meal with roasted vegetables such as broccoli rabe, zucchini, or asparagus. Garnish each individual plate with an extra sprinkle of freshly grated Parmesan cheese and a few cracks of black pepper. The casual yet impressive presentation makes it ideal for both busy weeknight family dinners and relaxed weekend gatherings with friends, offering maximum comfort with minimal hosting stress.

Easy Slow Cooker Ravioli Lasagna with Ground Beef

Prep 15 minCook 4 hRest 10 minTotal 4 h 25 minServes 6

Ingredients

• 1 lb ground beef
• 1 tsp Italian seasoning
• 24 oz marinara sauce
• 25 oz frozen ravioli
• 2 cups shredded mozzarella cheese
• 2 tbsp chopped fresh parsley

Instructions

1. Place a large skillet over medium-high heat. Add the ground beef and Italian seasoning. Cook the beef, breaking it up with a wooden spoon, until it is completely browned and reaches a safe internal temperature of 160°F (71°C). Drain any excess grease from the skillet.
2. Spread a thin layer of marinara sauce across the bottom of the slow cooker insert to prevent sticking. Arrange half of the frozen ravioli in an even layer over the sauce. Top the ravioli with all of the cooked ground beef, followed by half of the remaining marinara sauce.
3. Layer the remaining frozen ravioli over the beef and sauce. Pour the rest of the marinara sauce evenly over the top, covering the pasta completely. Sprinkle the shredded mozzarella cheese in an even layer over the entire surface.
4. Cover the slow cooker with its lid. Cook on low for 3 to 4 hours, or on high for 1.5 to 2 hours, until the pasta is tender and the cheese is fully melted and bubbling. Turn off the heat, scatter the fresh chopped parsley across the top, and let rest for 10 minutes before serving.
