1 10-ounce box frozen chopped spinach, thawed and squeezed dry

Heat oven to 350° F. Spoon 1/3 of the sauce into a 9-by-13-inch baking dish. Place 12 ravioli on top. Cover with the spinach and half the mozzarella. Add another layer of ravioli and the remaining sauce, mozzarella, and the Parmesan. Cover with foil and bake for 25 minutes. Uncover and bake until bubbly, 5 to 10 minutes more.
