Whether you know it as potatoes au gratin or scalloped potatoes, this bubbling casserole of creamy sliced potatoes and cheese will warm up any cold night. Start the cooking process on the stove by getting the sauce and potatoes warmed through. Then layer the potatoes, sauce, and cheese in the dish and bake until golden brown. Serve alongside glazed ham or steak for a rich and comforting meal.
