Cook beef in a large nonstick skillet over medium-high heat until browned, stirring to crumble. Drain well. Combine beef, rigatoni, sauce, and 1 cup mozzarella cheese in an 11 x 7inch glass or ceramic baking dish coated with cooking spray. Top with remaining 1/2 cup mozzarella cheese and 1/4 cup Parmesan cheese.
Bake, uncovered, at 350° for 20 minutes or until thoroughly heated.
