Meatball Ravioli Bake

3 (8 oz) packages frozen ravioli (or 1 25 ounce bag)

36 ounces marinara sauce

1 (14 ounce) package fully cooked miniature (cocktail-size) meatballs 

3 cups shredded mozzarella cheese

1/3 cup parmesan cheese

Spray a 13x9" baking dish (or two 8x8" dishes) with cooking spray.  Pour about 1/3 of the marinara sauce (12 ounces) into the prepared baking dish to cover bottom.  Arrange half of the frozen ravioli in a single layer over sauce.  Top with half of the meatballs.  Pour another 1/3 of marinara sauce over top.  Sprinkle with 1/2 of the mozzarella cheese.  Repeat layers once more, starting with ravioli.  Sprinkle parmesan cheese on top.  Cover tightly with foil & freeze.

To prepare:

Thaw completely.  Bake, covered, for 20 minutes.  Remove foil & bake, uncovered, for 20-25 minutes or until bubbly and hot in center.  Let stand 10 minutes before serving.
