Start your loaded potato casserole by baking eight potatoes then peel them.   Mash the peeled potatoes and mix with sour cream and Monterey Jack cheese.   Then spoon it into a 9 X 13  casserole dish.   If you have a small family then use 2 2-quart casserole dishes.   Cook one and refrigerate the other for later.
