A container for heating a food product with microwave energy having a wavelength. The container can comprise a generally circular centerline having an axis, and a receptacle comprising a sidewall extending at least partially around a cavity. At least a portion of the cavity can extend along at least a portion of the centerline. The sidewall can comprise an inner edge and an outer edge each being spaced apart from the axis of the centerline for at least partially retaining the food product in the cavity in proximity to the centerline.
