Onion Au Gratin
Peel and slice thinly three good-sized Spanish onions; Butter a baking dish, arrange in it a layer of the sliced onions, dust with salt and pepper, sprinkle over one tablespoonful of bread crumbs and one tablespoonful of melted butter. Continue in this order until the pan is filled. Bake in a moderate oven until the onions are tender; this will take about three-quarters of an hour. Over the top sprinkle a thick layer of grated cheese and return to the oven until it is melted and browned.
