Potato Au Gratin Recipe ingredients

To prepare this Potato Au Gratin Recipe, first chop or slice cold boiled potatoes. Add enough rich cream sauce to season nicely. Pour into an oiled baking pan, rub a slice of bread through a colander or strainer over the top, and press the crumbs down with a spoon, so they become moistened. Sprinkle with small bits of vegetable butter, and bake to a light brown color.
