A chafing dish is a portable, tabletop appliance used to keep food warm during buffets, banquets, or catered events. It typically consists of a metal frame, a water pan, a food pan, and a lid. Heat is provided by fuel burners (like Sterno cans) or electric heating elements placed beneath the water pan, which creates gentle, even steam to maintain food at serving temperature without overcooking. Chafing dishes come in various shapes—rectangular, round, or oval—and are often made of stainless steel for durability and easy cleaning. They are essential for professional catering and hospitality, ensuring dishes remain appetizing throughout service.
