Line a baking sheet with parchment paper.

Put the Parmesan cheese in 8 mounds on the parchment paper, about 2 tablespoons each.  Pat down lightly.

Sprinkle each mound of Parmesan with rosemary, pepper and garlic powder.

Bake at 350 degrees for 8-9 minutes, until golden brown. Let cool completely and gently remove to a paper towel to absorb excess oil.  Serve at room temperature or store in an airtight container for a week.
