Cook pasta until al dente in a pot of boiling, salted water.
Heat the marinara sauce in a large saucepan. Reserve about 1 1/2 cups of the sauce. Set aside about 1 tablespoon of the Parmesan. To the sauce, add the ricotta and remaining Parmesan and stir well. Cook over medium heat, stirring, for about 2 minutes. Add the cooked pasta and the butter and toss well. Top with the reserved marinara and mozzarella and sprinkle with Parmesan. Bake for 15 to 20 minutes, or until golden brown. Garnish with fresh basil.
