Welcome to My Kitchen! Craving comforting Italian food without the fuss? This Lazy Lasagna Casserole uses frozen ravioli as a shortcut, skipping traditional layering for a quick, cheesy, family-approved weeknight dinner.

Ingredients

Scale
  • 1 (25 ounce) package frozen cheese ravioli
  • 1 (24 ounce) jar marinara sauce (your favorite brand)
  • 1 cup ricotta cheese
  • 1 cup shredded mozzarella cheese, plus 1/2 cup for topping
  • 1/4 cup grated Parmesan cheese
  • 1 large egg
  • 1 teaspoon Italian seasoning
  • 1/2 teaspoon garlic powder

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
  2. In a large bowl, gently combine the ricotta cheese, 1 cup of mozzarella cheese, Parmesan cheese, egg, Italian seasoning, and garlic powder. Mix until the cheese mixture is uniform.
  3. Spread about 1 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. Do not thaw the ravioli first.
  5. Spread half of the ricotta cheese mixture evenly over the layer of ravioli.
  6. Spoon half of the remaining marinara sauce over the ricotta layer.
  7. Repeat the layers: the remaining ravioli, the remaining ricotta mixture, and the remaining marinara sauce.
  8. Sprinkle the remaining 1/2 cup of mozzarella cheese over the top layer of sauce.
  9. Cover the baking dish tightly with aluminum foil.
  10. Bake for 30 minutes covered.
  11. Remove the foil and bake for an additional 10 to 15 minutes, or until the cheese is melted, bubbly, and lightly browned.
  12. Let the Lazy Lasagna Casserole rest for 5 to 10 minutes before you cut and serve it.

Notes

  • For a heartier meal, brown 1 pound of ground beef or Italian sausage and mix it into the marinara sauce before assembling the casserole.
  • If you prefer cottage cheese over ricotta cheese, you can substitute it cup for cup in this recipe.
  • This recipe is a great option for a simple family pasta dish or a quick weeknight Italian dinner.
