Parchment is excellent as far as non stick. My wife uses parchment for cookies all the time and we use it for many other kitchen duties.
But use caution in a toaster oven. The heating elements are very close to the wire shelves.
I put a roll wrapped in parchment paper into my toaster oven once and it started to burn the paper.
No big deal resulted except for the roll was ruined. Just my experience.
Thanks for the heads up about the parchment paper! I think a silicone mat is what I'll use.
