Parmesan Crisp Recipe
- Parmesan Cheese, grated
Simply spoon the grated Parmesan cheese into chip-sized, relatively thin dollops on a hot griddle. The cheese will melt, then turn crispy. At this point, use a spatula to flip the crisps over and lightly brown the other side. Then remove from the griddle onto a plate.
If you don’t have a griddle, you can spoon the Parmesan cheese into chip-sized, relatively thin dollops on a cookie sheet or two. Place the cookie sheets in your oven under the broiler and watch them melt and lightly brown. At this point, remove them from the oven and use a spatula to transfer them onto a plate.
