Preheat your oven to 400°F (200°C). This will ensure your crisps cook evenly and become perfectly crispy.
Line a baking sheet with parchment paper. This step is crucial as it prevents the cheese from sticking and makes for easy removal.
In a mixing bowl, combine the grated Pecorino Romano and Parmesan cheese. Make sure they are evenly mixed to create a harmonious flavor.
Sprinkle in the freshly ground black pepper, mixing thoroughly to ensure that every cheese piece is seasoned.
Scoop tablespoon-sized portions of the cheese mixture onto the prepared baking sheet, spacing them about 2 inches apart. They will spread as they bake, so give them room to puff up.
Place the baking sheet in the preheated oven and bake for 5-7 minutes, or until the edges are golden and the cheese has melted into beautiful, bubbly crisps.
Remove the baking sheet from the oven and let the crisps cool for a few minutes before transferring them to a serving platter. Sprinkle with additional black pepper for an extra kick.
