Meta Description: Learn how to make easy crockpot ravioli lasagna with this step-by-step recipe, including ingredients, storage tips, service suggestions, and FAQs.

Ingredients

1 lb ground beef or Italian sausage
1 small yellow onion, diced
2 cloves garlic, minced
24 oz jar marinara or pasta sauce
25 oz package frozen cheese ravioli (do not thaw)
15 oz container ricotta cheese
2 cups shredded mozzarella cheese, divided
1/2 cup grated Parmesan cheese
1 large egg
1 tsp Italian seasoning
Salt and black pepper to taste
Fresh parsley, chopped (for garnish)

Instructions

Brown the meat: Heat a skillet over medium-high heat. Add the ground beef or Italian sausage and diced onion, cooking until the meat is fully browned and the onions are translucent. Drain any excess grease. Stir in the minced garlic and cook for about 1 minute until fragrant.
Combine with sauce: Pour the marinara sauce into the skillet with the cooked meat mixture, stirring well to combine. Remove from heat and set aside.
Mix the cheese filling: In a medium bowl, combine the ricotta cheese, 1 cup of mozzarella cheese, Parmesan cheese, egg, Italian seasoning, salt, and pepper. Stir until smooth and well incorporated.
Layer the slow cooker: Lightly grease your slow cooker insert with non-stick cooking spray. Spread a thin layer of the meat sauce (about 1 cup) across the bottom of the slow cooker.
Add ravioli: Arrange a single layer of frozen cheese ravioli over the sauce, covering the bottom as much as possible.
Add cheese layer: Spoon dollops of the ricotta mixture over the ravioli and gently spread it out.
Repeat layers: Continue layering the ingredients—meat sauce, ravioli, and the cheese mixture—until you run out of ingredients, finishing with a final layer of meat sauce on top.
Cook: Cover and cook on LOW for 3 to 4 hours or on HIGH for 2 hours, until the ravioli is tender and the edges are bubbling.
Melt the topping: Sprinkle the remaining 1 cup of mozzarella cheese over the top of the lasagna. Cover the slow cooker for about 10 to 15 minutes until the cheese is completely melted and gooey.
Garnish and serve: Sprinkle with chopped fresh parsley before dishing out.

Service Suggestions

Serve alongside a crisp, acidic garden salad tossed in a sharp vinaigrette to cut through the rich, heavy cheeses.
Pair with warm garlic bread or cheesy breadsticks to mop up any leftover sauce.
Roasted garlic parmesan green beans or steamed broccoli make fantastic vegetable sides.

Storage Tips

Refrigerator: Store leftover lasagna in an airtight container in the fridge for up to 3 to 4 days.
Freezer: You can freeze cooked portions for up to 2 months. Make sure they are cooled completely and stored in a freezer-safe container.
Reheating: Reheat individual portions in the microwave for 1 to 2 minutes, or warm larger amounts in an oven-safe dish at 175°C until heated through.

Frequently Asked Questions

Can I use fresh ravioli instead of frozen? Yes, but you will need to reduce the cooking time by about 30 to 45 minutes if cooking on LOW, as fresh pasta cooks much faster than frozen pasta and can become overly mushy.

Do I need to boil the ravioli first? No, absolutely not. The frozen ravioli will cook entirely in the slow cooker thanks to the moisture from the marinara sauce.

Can I make this vegetarian? You can easily omit the ground meat entirely and substitute it with sliced mushrooms, zucchini, or spinach sautéed in olive oil, or simply stick to a cheese-and-sauce version.

This effortless spin on a classic Italian favorite proves you don’t need hours of kitchen prep to put a hearty, crowd-pleasing dinner on the table.
