Freak Out for Frico!
I saw a couple of contestants making frico out of aged cheddar on Chopped and decided to make a sampler of Parmesan, Romano, and aged cheddar fricos. They didn't last long enough to photograph.
Grate cheese. Cover a cookie sheet with parchment paper. Arrange cheese in several piles on paper. Bake six to eight minutes at 350°.
