A passive heater including a carriage actuatable to move along a cooking surface and a cover. In one exemplary embodiment, the carriage may be positioned on a guide bar to direct movement of the carriage along the cooking surface. The cover may be connected to the carriage and positionable near the cooking surface. Advantageously, positioning the cover near the cooking surface provides for the retention of nearby heat. Thus, the top surface of a food item cooking on the cooking surface may be heated by placing the cover over the food item. In another exemplary embodiment, the cover has a lifted position and a lowered position. By moving the cover from the lifted position to the lowered position, the cover may contact the cooking surface to surround food cooking thereon. In another exemplary embodiment, the lowered positioned may be spaced upwardly from the cooking surface, allowing the cover to cap food thereon.
