An apparatus for heating a food item in a microwave oven is disclosed which has heater regions in combination with a reflective lattice structure. The combination of the reflective lattice structure and heater regions provides a food heating device which substantially maintains its reflectance, absorbance and transmittance during microwave heating. Substantial uniformity of heating is also achieved. The reflectance, transmittance and absorbance of the food heating device can be adjusted by changing the relative configuration and construction of the lattice structure and the heater regions.
