Instructions

1. 1 Spray a 9x13-inch baking dish with cooking spray.

3. 3 Pour 1 cup marinara sauce in the bottom of the prepared baking dish. Arrange 1/2 of the ravioli in a single layer over the sauce. Pour 1 cup sauce over the ravioli, then spread ricotta mixture over the sauce and top with 1/2 cup mozzarella cheese. Top with remaining ravioli, remaining sauce, and remaining mozzarella.
4. 4 Cover with parchment paper and then cover tightly with foil. Freeze for up to one month.
5. 5 When ready to cook, preheat the oven to 350 degrees F (175 degrees C).
6. 6 Place frozen covered lasagna in the preheated oven and bake for 1 1/2 hours. Uncover and bake until golden and bubbly, about 20 more minutes. Let stand for 10 minutes before serving.
