Grate fresh Parmesan cheese finely. If desired, mix in black pepper, chopped herbs, or spices to enhance the flavor.
Heat a non-stick pan over medium heat. No oil or butter is needed since the cheese will release its natural fats.
Place about 1 tablespoon of grated Parmesan cheese in the pan for each tuile. Spread it out lightly into a thin, even circle. Leave some space between each round as they will spread slightly.
Let the cheese melt and bubble in the pan. It will transition from melted to golden and crispy. This usually takes 1-2 minutes.
Using a spatula, carefully flip the tuile to cook the other side for another 10-15 seconds. Be gentle, as the tuiles are delicate.
While still warm, remove the tuile from the pan and quickly drape it over a rolling pin, bowl, or any curved surface to create a classic tuile shape. If you prefer flat tuiles, let them cool on a flat surface.
Allow the tuiles to cool completely. They will harden as they cool, becoming crisp. Serve as a garnish, snack, or appetizer.
