The Fried Onions are packaged and can be purchased in food stores as a prepared food that is fried for use as an ingredient for various recipes. French Fried Onions are made from small diameter slices of onion that are covered with a batter and then deep fried into small, crisp pieces of onion. The Onions are then most often used as toppings for casseroles or for use in coating foods, similar to a breadcrumb. This type of Fried Onion is not to be confused with the larger version of Fried Rings that are served as appetizers.
