To make the Parmesan crisps, preheat the oven to 375 degrees F and line a baking sheet with parchment paper. Measure 1/4 cup grated Parmesan in small mounds on the parchment and spread 1/8-inch thick. Bake until bubbly and beginning to brown, 9 minutes. Allow to cool slightly on the baking sheet before removing to a wire rack to cool completely.
