A food support for holding food items during cooking in an oven. The food support includes a reinforcement structure including a perimeter frame extending around and defining a substrate placement area. At least one cross bar extends between two opposing portions of the support frame and beneath the substrate placement area. A removable and replaceable substrate insert is sized to be placed on the substrate placement area for receiving food items thereon. A securing element can be connected to the reinforcement structure for securing the substrate insert on the substrate placement area. A holding device including a holding surface connected to a clamping element, where the holding surface is adapted to support a bottom of the food support and the clamping element is adapted to clamp over a top surface of the food support, can be used to securely introduce and/or remove the food support from an oven.
