The microwavable heat stand is an apparatus that allows microwave energy to directly reach a food item along surfaces that normally rest on a plate, a bowl, or any other comparable dish. The apparatus includes a base plate, a plurality of dividers, and a plurality of waveguide channels. Each of the plurality of dividers includes a proximal end and a distal end. The plurality of dividers is distributed across the base plate. The proximal end of each of the plurality of dividers is connected adjacent to the base plate. Consequently, the distal end for each of the plurality of dividers provides a surface for which the food item may rest. Each of the waveguide channels is delineated by the base plate and a pair of adjacent dividers from the plurality of dividers, allowing microwave energy to flow from the outer edge of the base plate to the center of the base plate.
