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