- 1 cup finely grated Parmesan cheese
Preheat oven to 400 degrees.
Line a baking sheet with a nonstick baking mat. Sprinkle cheese in a thin even layer on baking mat to form a rectangle. Transfer to oven and bake until cheese melts and just begins to turn golden, 8 to 10 minutes.
Remove from oven and let cool slightly on baking sheet before gently removing; let cool completely before using.
