Ingredients
  

  • 1/2 cup grated Parmesan cheese
  • 1/4 cup chopped fresh parsley
  • 1 large egg
  • Salt to taste
  • Pepper to taste
  • 2 cups shredded mozzarella cheese
  • Optional: Red pepper flakes
  • Optional: 1/2 cup sauteed onions
  • Optional: 1/2 cup sauteed bell peppers
  • Optional: 1/2 cup sauteed mushrooms
  • Optional: 1/2 cup sauteed spinach
  • Optional: 1 pound ground beef, Italian sausage, or turkey sausage, browned and drained

Equipment

  • Slow Cooker (6-quart or larger)
  • Medium bowl
  • Measuring cups
  • Measuring spoons
  • Spoon or spatula
  • Ladle

Method
 

  1. In a medium bowl, combine the ricotta cheese, Parmesan cheese, parsley, and egg. Season with salt and pepper. Mix well until everything is nicely combined.
  2. Spread a thin layer of marinara sauce on the bottom of your slow cooker to prevent sticking.
  3. Arrange a layer of frozen ravioli over the sauce. You can slightly overlap them if needed.
  4. Dollop spoonfuls of the ricotta mixture over the ravioli. Try to spread it as evenly as possible.
  5. Sprinkle about 1/3 of the mozzarella cheese over the ricotta.
  6. Pour another layer of marinara sauce over the mozzarella.
  7. Repeat layers: ravioli, ricotta mixture, mozzarella, marinara sauce, until all ingredients are used, ending with a final layer of marinara sauce and mozzarella cheese on top.
  8. Cover the slow cooker and cook on low for 3-4 hours, or on high for 1.5-2 hours, or until the ravioli are tender and the cheese is melted and bubbly. Cooking times can vary depending on your slow cooker, so keep an eye on it!
  9. Once cooked, let the lasagna sit for about 10 minutes before serving. This helps it to set up a bit.
  10. Garnish with fresh parsley, if desired.
  11. Serve hot and enjoy!

Notes

Don't thaw the ravioli before using them in the crockpot, as this will cause them to become mushy. Use a high-quality marinara sauce for the best flavor. For a richer flavor, try using a combination of mozzarella, provolone, and Parmesan cheese. If the lasagna is too watery, place a paper towel under the lid of the slow cooker to absorb excess moisture. Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or oven until heated through.
