Au gratin is a French culinary technique. It is simply a dish covered with bread crumbs or grated cheese and butter. It is baked until it is forms a light golden crust. This is my version a this classic French dish. It is rich in flavor and makes an elegant side dish for dinner or on a buffet. I also like to use half Yukon Gold potatoes and half sweet potatoes to create a delicious Thanksgiving side dish.
