Preheat oven to 400ºF. Bring a large pot of water to a boil. Add pasta to boiling water and cook until al dente, approximately 7-8 minutes. Drain. In a bowl, combine cooked pasta with marinara sauce and 1 cup shredded mozzarella. Place pasta in 3-quart casserole dish and cover with remaining 2 cups of shredded mozzarella and shredded basil. Baked until cheese becomes bubbly and lightly brown, approximately 15 minutes.
