Why Aluminum Foil Has a Shiny and a Dull Side (Page 2 ) | March 7, 2025

Yes! If you’re using non-stick foil, there is a difference between the two sides. The non-stick coating is only applied to one side, and that’s the side you should use. Typically, the dull side is the non-stick side, but you can confirm by checking the label on the packaging, which will clearly designate the “non-stick side.”
