A food service assembly for heating and maintaining trays of food hot while food can be served therefrom has a well for holding the tray or trays of food, the well including side walls of stainless steel, a relatively thick bottom plate made of a highly thermally conductive material such as aluminum for spreading heat out within the well, a resistive heating blanket affixed to the underside of the base plate for heating the base plate, the heating blanket covering most of the underside of the base plate, a layer of high temperature insulation such as ceramic fiber mat underneath the heating blanket and within the side walls, and a layer of insulating material such as phenolic sheet material insulating the side walls from the top surface of the assembly near the well.
