Creamy French Gruyere cheese and Proscuitto ham makes this American classic something really special. Dress it up with a bottle of wine and crusty bread or make it kid friendly by topping it with crushed potato chips toward the end of cooking time.
Thaw completely. Preheat oven to 400 degrees. Spray a 8X10 baking dish with nonstick cooking spray. Bring a pot of water to a boil. Add penne pasta and boil for 10-12 minutes. Drain well and place back into pot. Pour contents of milk/prosciutto bag into pot on top of pasta and stir. Place into prepared baking dish. Sprinkle gruyere cheese on top. Bake uncovered until cheese melts and thickens, about 15-20 minutes. Allow to cool 5-10 minutes.
