A food warming cabinet includes inner and outer spaced wall members, and an openable and closeable door forming an internal compartment in which heated food is maintained. A heated cable arrangement is interposed between the outer and inner wall members and provides a source of heat to keep the food warm. Heat insulation encases the heating cable arrangement and is disposed between the inner and outer wall members to support the heating cable arrangement and maintain the heat developed by the heating cable arrangement in the internal compartment. A drip pan is mounted within the internal compartment for catching drippings from the heated food maintained therein. A solenoid valve projects through the wall members for selectively delivering a spray film of water from an outside source to the drip pan. A controller is associated with the internal compartment for activating the solenoid valve for a predetermined time in response to opening of the door, whereby evaporation of moisture from the heated food lost in the opening of the door is replenished by evaporation of the water film deposited in the drip pan.
