Improved disposable three layered pads for collecting cooking grease produced during the cooking of fatty foods particularly in the cooking area of a microwave oven as described in U.S. Pat. No. 5,814,396. These pads comprise (a) a top grease absorbing layer having at least one ply of a grease absorptive sheet; (b) a middle grease and high temperature resistant layer; and (c) a bottom layer composed of an anti-stick heat insulating sheet. The pad is dimensioned to cover a substantial portion of the bottom cooking area of a microwave oven when used in these devices. The top layer is from 2 to 50 times thicker than the middle and bottom layer. The improvement comprises a small yet effective amount of anti-stick coating on the top layer of these three layered pads. These anti-stick coatings may be selected from such substances as vegetable oils, animal fats and synthetic lubricants.
