The cone-shaped or dome-shaped sheet of waxed paper or freezer paper having a moisture retarding coating on at least the surface of the paper facing an underlying dish bearing food and positioned within a microwave oven, and being microwave transparent traps moisture condensing on the interior surface thereof for revaporization for return to the food being heated and/or cooked while preventing the dripping of condensed moisture directly onto the food within the underlying dish. Preferably the conical or dome-shaped cover is mechanically embossed to form vertically spaced annular concave cavities facing inwardly to trap the moisture running by gravity down the interior surface of the cover within the cavities for revaporization. Additionally, circumferentially spaced reinforcing ribs may be formed over the height of the cover to maintain the cover one or dome shaped configuration throughout the microwave oven heating process. An open mesh frame may be employed for supporting the cover overlying the dish bearing the food. Integral flaps cut out of the cover about three sides, with the exception of a horizontal hinge allow the flaps to open outwardly and curl upwardly under excessive moisture accumulation within the cover, and to close upon cooling of the cover at termination of the microwave oven operation. A unitary, folded under, reinforcing lip at the bottom of the conical or dome-shaped cover captures condensed moisture to facilitate revaporization and return of all moisture to the food being heated or cooked.
