Preheat oven to 400℉ and line a baking sheet with parchment paper
Though exact amounts aren't necessary, I like to take about 2 tablespoons of cheese at a time and shape into a 3-4 inch circle on your baking sheet. This is not an exact science- eyeballing is fine! Tips: for nice circles, use a mason jar lid (large or small) to help shape. Note: you don't necessarily have to shape them into circles, you can simply sprinkle cheese in light layer directly on your parchment-lined baking sheet if you prefer, and break into pieces after baking. This works particularly well if you're just breaking them up on a salad, etc.
Bake for 6-7 minutes. You'll want to watch for color as your sign. They'll change from the creamy white parmesan color to slightly golden.
Remove from oven and cool on parchment for a minute and then use a metal spatula to transfer to a cooling rack. Store cooled crisps in an airtight container
Notes
Store finished cooled crisps in an airtight container at room temperature.
