Step 1

Arrange a rack in the middle of the oven and heat the oven to 400ºF. Meanwhile, line a rimmed baking sheet with parchment paper or a silicone baking mat. Grate 2 ounces Parmesan cheese on the smaller (not smallest) holes of a box grater into fine shreds (about 3/4 cup).

Step 2

Spoon the cheese onto the baking sheet in 12 piles (about 1 tablespoon each), spacing them evenly apart. Gently pat each pile into an even 2 1/2-inch round with your fingers.

Step 3

Bake until evenly light golden brown, 6 to 7 minutes. Let cool for at least 3 minutes on the baking sheet, they will crisp up as they cool. Loosen with a thin knife or offset spatula. If they are not as crisp as you’d like, return to the oven, checking every minute, until slightly darker in color. If making more than one batch, blot the excess oil from the baking sheet with paper towels before reusing.
