01 - Preheat oven to 375°F. Grease a 9x13-inch baking dish.
02 - Boil the pasta in salted water until just al dente, about 8 minutes. Drain and set aside.

04 - Add cooked pasta to the cheese mixture, tossing to coat evenly.
05 - Spread 1 cup marinara sauce on the bottom of the baking dish. Layer half of the pasta mixture over sauce. Add 1 1/2 cups marinara sauce and sprinkle 1/2 cup mozzarella.
06 - Add remaining pasta mixture, then top with remaining marinara sauce. Sprinkle with remaining mozzarella and Parmesan.
07 - Cover with foil and bake for 25 minutes.
08 - Remove foil and bake an additional 15 minutes until cheese is bubbly and golden.
09 - Let stand 10 minutes before serving. Garnish with additional basil if desired.
