Food can be cooked in an accelerated cooking oven by placing the food on a heat-resistant liner and, in particular, a liner formed from vegetable parchment filled with an inert inorganic filler such as titanium dioxide. The parchment paper is coated on one or both sides with a silicone release coating. In one embodiment of the present invention, the parchment paper can be creped from about 5 to about 12%. This liner is suitable for use in an accelerated cooking oven to prevent messes from forming in the oven without significant discoloration, burning or flaking.
