Coat the bottom and sides of a 9X13-inch baking dish with the butter. Heat the whipping cream and cheese in a saucepan over medium heat until blended, stirring frequently. Remove from the heat.
Layer the potatoes, salt, pepper and cheese sauce 1 / 2 at a time in the prepared baking dish, arranging the potato slices so they are slightly overlapping. Baked, covered,
at 400 degrees for 30 minutes; remove the cover. Bake for 30 minutes longer.
