Lightly grease a 9 by 13-inch (23 by 33 cm) baking dish. Spread about 1 cup of meat sauce across the bottom, then arrange 6 noodles over the sauce, overlapping slightly.

Spread half of the creamy cheese filling over the noodles. Add one third of the mozzarella, half of the remaining meat sauce, and 1/4 cup parmesan. Repeat with the remaining noodles, cheese filling, another third of mozzarella, remaining meat sauce, and 1/4 cup parmesan.

Bake covered for 25 minutes. Remove the foil and bake for 25-30 minutes more, until bubbling around the edges and golden on top. Rest for 15 minutes before slicing.
