Remove skillet from heat, and mix in 2 cups cheese until melted. Transfer to the prepared casserole dish. Bake 25 minutes in the preheated oven. Sprinkle with remaining cheese, and continue baking 5 minutes, until cheese is melted. Recipe Tip You can use bulk sausage instead of ground beef if you prefer.
