Make this simple, cheesy lasagna casserole using frozen cheese ravioli instead of traditional noodles. It is a fast, family-friendly weeknight dinner requiring minimal preparation.

Ingredients

Scale
  • 1 (20 ounce) package frozen cheese ravioli or tortellini
  • 1 (24 ounce) jar marinara sauce
  • 1 (15 ounce) container ricotta cheese
  • 1 large egg
  • 1 teaspoon dried Italian seasoning
  • 1/4 teaspoon salt
  • 1/4 teaspoon black pepper
  • 2 cups shredded mozzarella cheese

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
  2. In a medium bowl, combine the ricotta cheese, egg, Italian seasoning, salt, and pepper. Mix until smooth.
  3. Spread about 1/2 cup of the marinara sauce evenly over the bottom of the prepared baking dish.
  4. Arrange half of the frozen ravioli in a single layer over the sauce.
  5. Spread half of the ricotta mixture over the ravioli layer.
  6. Sprinkle one cup of the mozzarella cheese over the ricotta.
  7. Spoon half of the remaining marinara sauce over the mozzarella.
  8. Repeat the layers: remaining ravioli, remaining ricotta mixture, remaining marinara sauce, and top with the remaining one cup of mozzarella cheese.
  9. Cover the baking dish tightly with aluminum foil.
  10. Bake for 30 minutes.
  11. Remove the foil and bake for an additional 10 to 15 minutes, or until the cheese is melted and bubbly.
  12. Let the casserole rest for 5 minutes before serving.

Notes

  • For a meatier dish, brown 1 pound of ground beef and mix it into the jar of marinara sauce before layering.
  • You can substitute frozen meat ravioli for cheese ravioli if you prefer.
  • This recipe is freezer friendly; assemble completely, cover tightly, and freeze unbaked for up to three months. Thaw overnight in the refrigerator before baking as directed, adding 10 minutes to the covered baking time.
