Potato skins are a snack food or appetizer made of unpeeled potato halves, hollowed and dressed with bacon, cheddar cheese and green onions. They are commonly found on the menus of casual dining restaurants such as T.G.I. Friday's, which is known for serving them.

While commonly eaten in restaurants, these snacks are also commonly made in homes across America. They have become a household favorite since they were introduced in American life. They are used as snacks for events such as The Super Bowl and other large events.
