Q: Is there a right side to use when placing parchment paper in a baking pan?

A: No. And while we’re on the subject, there’s no right or wrong side to foil, either, said Rebecca Danchise, spokeswoman for Reynolds Kitchens in Richmond, Va.

“The dull and the shiny are just part of the manufacturing process, but it won’t affect your cooking times,” Danchise said. The only time it matters which side is up is when using quick-release foil, which has a nonstick coating on the dull side.
