Once shells are cooked and cool, fill each shell with (about 2 heaping tbsp) cheese mixture and place on a large baking dish, or two smaller dishes, covering the bottom of the dish with a little sauce.
Preheat oven to 375F.
Top shells with half of the sauce, cover with foil and bake 40 minutes; uncover foil and bake 5 more minutes.
Serve with additional sauce on top and garnish with fresh basil, if desired.
