A food warming oven for holding and warming food items includes a base, a frame extending upward from the base, and at least one generally transparent heating shelf disposed above the base by the frame. Each shelf is configured to support food items, and each shelf includes a transparent substrate and a transparent resistive coating deposited on the substrate. The food warming oven also includes a power feed electrically coupled to the resistive coating of each transparent heating shelf to heat that shelf and the food items supported by that shelf. Due to the generally transparent nature of each heating shelf, the food items disposed below the heating shelf are viewable from overhead the heating shelf.
