Ingredients

Sauce Mixture

  • 1 24 oz jar marinara or pizza sauce
  • 1 14 oz can diced tomatoes, drained
  • 1 tsp Italian seasoning
  • 1 tbsp minced garlic

Main Ingredients

  • 1 pound Italian sausage, browned
  • 1 25 oz package frozen cheese ravioli
  • 1½ cups shredded mozzarella cheese
  • 20–25 pepperoni slices
  • ¼ cup grated parmesan cheese
  • 2 tbsp chopped parsley

Instructions

  1. Prepare the sauce mixture: In a bowl, combine the marinara sauce, drained diced tomatoes, Italian seasoning, and minced garlic thoroughly to blend all the flavors.
  2. Prepare the slow cooker: Lightly grease the inside of the slow cooker to prevent sticking. Spread a thin layer of the sauce mixture evenly on the bottom of the slow cooker.
  3. Add first layer: Place half of the frozen cheese ravioli in an even layer over the sauce, followed by half of the browned Italian sausage evenly distributed on top.
  4. Add sauce layer: Spoon half of the remaining sauce mixture over the ravioli and sausage layer to ensure even coverage.
  5. Cheese and pepperoni layer: Sprinkle half of the shredded mozzarella cheese over the sauce, then add half of the pepperoni slices evenly across the top.
  6. Repeat layers: Repeat the layering process with the remaining ravioli, sausage, sauce, mozzarella cheese, and pepperoni slices, creating a second layered casserole.
  7. Top with parmesan: Sprinkle the grated parmesan cheese evenly over the top layer to add a savory finish.
  8. Cook: Cover the slow cooker with the lid and cook on LOW for 3 to 4 hours or on HIGH for 1½ to 2 hours. Cook until the ravioli is tender and the cheese is fully melted.
  9. Garnish and serve: Once cooked, sprinkle the chopped parsley over the top just before serving for a fresh touch and enhanced flavor.
  10. Optional finishing tip: For a nicer presentation, add some extra pepperoni slices on top during the last 30 minutes of cooking.

Notes

  • Frozen ravioli holds its texture better during slow cooking than fresh ravioli.
  • Use a thicker marinara sauce to prevent the casserole from becoming watery.
  • Layering ingredients helps everything cook evenly and creates an appealing casserole look.
  • Adding extra pepperoni on top near the end of cooking gives the dish a more attractive finish.
