Preheat oven to 375°F and lightly spray a 9" x 13" casserole dish with cooking spray. Bring a pot of water to boil and cook pasta until "al dente" according to package directions. Drain and pour into a large mixing bowl.
To the pasta, add the chicken, marinara sauce, 1 cup of parmesan cheese and 1 cup of the mozzarella cheese. Stir together until evenly mixed. Pour the mixture into the casserole dish and spread evenly. Sprinkle the remaining mozzarella cheese on top.
Bake for about 50-60 minutes or until the sauce is bubbly and the cheese is starting to turn a golden brown on top. Allow to cool for 10-15 minutes before serving. Top with fresh basil and more parmesan cheese if desired.
