Slow Cooker Ravioli Lasagna is a no-boil, cheesy lasagna recipe made with frozen ravioli, ground beef, marinara sauce, and mozzarella cheese. It’s the ultimate comfort food that practically cooks itself in a crockpot.

Ingredients

Scale
  • 25 oz. frozen ravioli (do not thaw)
  • 1 lb. ground beef (or mild sausage)
  • 1 cup white onion, diced
  • 1/2 tsp salt
  • 1/4 tsp pepper
  • 1/4 tsp garlic powder
  • 1/2 tsp dried oregano (leaf, not ground)
  • 24 oz. marinara sauce
  • 8 oz. shredded mozzarella cheese (about 2 cups)
  • Non-stick cooking spray

Instructions

  1. In a skillet over medium-high heat, cook ground beef with diced onion, salt, pepper, garlic powder, and oregano until browned. Keep 2–3 tablespoons of liquid for moisture.
  2. Spray the inside of your slow cooker with non-stick spray.
  3. Pour half of the marinara sauce into the bottom of the slow cooker.
  4. Layer half of the frozen ravioli over the sauce in a single layer (some overlap is okay).
  5. Spread all of the cooked meat mixture evenly over the ravioli.
  6. Add the remaining frozen ravioli over the meat layer.
  7. Pour the rest of the marinara sauce on top.
  8. Sprinkle the shredded mozzarella cheese evenly over the top layer.
  9. Cover and cook on LOW for 4 hours (or HIGH for 2–2.5 hours).
  10. Serve hot and enjoy!

Notes

  • Do not thaw the ravioli before adding to the slow cooker.
  • You can use Italian sausage, soy crumbles, or meatballs instead of ground beef.
  • Try Alfredo or salsa as a sauce variation for different flavor profiles.
  • Add veggies like spinach or zucchini for extra nutrition.
  • Leftovers can be refrigerated for 4 days or frozen for up to 2 months.
