National Rotisserie Chicken Day is observed annually on June 2, worldwide. This unofficial food holiday celebrates the rotisserie chicken, a dish that has been enjoyed since the Middle Ages and became widely available to consumers in the 1990s. The holiday was founded by Boston Market, a restaurant chain known for popularizing packaged rotisserie chickens, and has been celebrated since 2015. People typically celebrate by indulging in delicious rotisserie chicken, which can be purchased at supermarkets or local delis, or by cooking it at home. In Peru, a notable variation called pollo a la brasa, a spit-roasted chicken served with fries and sauces, is considered a national dish and reflects the popularity of rotisserie chicken in different cultures.
