In a 23 x 33 cm (9 x 13 inch) baking dish, spread a thin layer of meat sauce on the bottom. Arrange a layer of noodles over the sauce. Evenly spread one third of the ricotta mixture over the noodles, followed by a portion of shredded mozzarella. Repeat the layering (sauce, noodles, ricotta, mozzarella) two more times. Finish with remaining meat sauce, mozzarella, and a generous sprinkle of grated Parmesan on top.
