Broasting is a method of cooking chicken and other foods using a pressure fryer. The technique was invented by L.A.M. Phelan in the early 1950s and is marketed by the Broaster Company of Beloit, Wisconsin, which Phelan founded.
Broasting equipment and ingredients are marketed only to service and institutional customers, including supermarkets and fast food restaurants. They are not available to the general public. The method essentially combines pressure cooking with deep frying chicken that has been marinated and breaded. The company licenses the "broasted" trademark to more than 5,510 purchasers of its equipment who follow its specifications and recipes and undertake a periodic certification process. The arrangement is not a traditional franchise in that the licensee does not owe ongoing royalty payments.
Many modern fast food chains also deep fry chicken under pressure, but use different recipes or equipment from one of several alternate suppliers. Other companies use more conventional deep fryers.
Broasted chicken remains highly popular in countries such as Saudi Arabia and Pakistan. Many restaurants and fast-food chains in these countries have the word "broast" in their names.
