Heat oven to 400 (200 C) degrees and line a baking sheet with parchment paper.
Lay the prosciutto slices on a rimmed baking sheet lined with parchment paper so that they don't overlap, curling the edges like a nest so they don't get too brown.
Bake until the slices start to shrivel and turn golden, 9-12 minutes. Keep your eye on it, as the prosciutto can go from crisp to burned quickly.
Cool on a rack (they will crisp up as they cool). Break into large pieces or crumbles to sprinkle over whatever you like.
Notes
Prosciutto chips will keep for weeks in a covered container in the fridge.
Gently heat in a skillet for a few minutes over medium heat to re-crisp.
