Spread ½ cup of spaghetti sauce on the bottom of 13x9 pan. Add a layer of ravioli (about ½ of the bag), and sprinkle with Italian seasoning. Top with ½ mozzarella cheese. Spread 1 ½ cups sauce over the cheese. Top with remaining ravioli, and lightly sprinkle with Italian seasoning. Top with 1 ½ cups of sauce, making sure that all ravioli is covered, add more or less sauce as desired.
Cover with foil, and bake in 350° oven for 30 to 35 minutes or until bubbling. Remove foil, and top with remaining mozzarella and parmesan cheeses. Sprinkle with Italian seasoning, and bake another 5 minutes or until cheese is melted.
