Potato skins are simple American appetizers consisting of unpeeled potato halves that have been hollowed out, deep-fried, then topped with cheese, bacon, or sour cream. They were originally invented as a way to turn potato peels into a profitable meal.
Depending on who you ask, there are three restaurants credited with the invention of this popular appetizer in the 1970s: R. J. Grunts in Chicago, TGI Fridays restaurant chain, or the Prime Rib restaurant in Washington, DC.
