Spread about 1 cup of the sauce on the bottom of 13x9-inch baking dish. Top with 3 of the lasagna noodles. Spread 1/2 of the cheese mixture over noodles. Repeat sauce, noodles and cheese layer once. Top with remaining noodles and sauce, making sure to cover noodles with sauce. Sprinkle with remaining 1/2 cup mozzarella cheese and Parmesan cheese. Cover with foil.
