Costco sells a baking mat that replaces parchment paper. I will try them tonight!I think there's a certain type of foil that works - Quick Release, or something like that from Reynolds Wrap. But you should be able to find parchment paper in the same aisle as the foil . . . I know I forgot the parchment once & I actually bent a stainless steel turner trying to get the crisps off the pan.
