Preheat your oven. Begin by preheating your oven to 375°F. Line a baking sheet with parchment paper or a silicone baking mat.
Portion out the cheese. Take small heaps (about 1 tablespoon each) of grated Parmesan cheese and place them on the prepared baking sheet. Make sure to space them a few inches apart, as they will spread during baking.
Shape and flatten. Gently flatten each heap of cheese with the back of a spoon to create a thin, even layer. You can shape them into rounds or ovals, but leave some space between them to allow for spreading.
Bake to perfection. Place the baking sheet in the preheated oven and bake for about 5-7 minutes, or until the crisps turn a beautiful golden brown color. Keep a close eye on them, as they can go from perfect to overdone quickly.
Cool and enjoy. Remove the Parmesan crisps from the oven and let them cool on the baking sheet for a few minutes. They will continue to crisp up as they cool. Once they're completely cool and firm, carefully peel them off the parchment paper or baking mat.
