Wikipedia
Onion rings are a form of appetizer or side dish commonly found in the United States, Canada, United Kingdom, Ireland, Australia, New Zealand, and some parts of Asia. They generally consist of a cross-sectional "ring" of onion (the circular structure of which lends itself well to this method of preparation) dipped in batter or bread crumbs and then deep fried; a variant is made with onion paste. Onion rings are sometimes accompanied by condiments including ketchup, mayonnaise or other sauces.
