Abstract: A paper cooking utensil includes a paper cooking utensil formed into a food containing part made of a paper sheet. The paper sheet is sealed by an adhesive to form into each of the side sections and a bottom section, with the upper edge of each of the side sections being a flange section acting as a lip for holding the paper cooking utensil. Each of the flange sections is foldably connected along a folded line which folds down outwardly, the central area of the bottom section being attached with an aluminum foil sheet having a geometric shape. The aluminum foil sheet is fixed to the top surface of the bottom section by applying an adhesive only on two edges of the opposite sides, and the aluminum foil sheet is porous and has a thickness range of 10-50 microns with an area of no less than 60 square centimeters.
