Preheat oven to 375 degrees. Line two rimmed baking sheets with parchment paper. Divide prosciutto between baking sheets, laying them flat. Bake until fat turns golden and meat is darker, about 15 minutes (rotating baking sheets from top to bottom halfway through baking time). Using tongs, carefully transfer prosciutto to paper towels to drain (it will crisp as it cools). Crispy prosciutto can be used like bacon, in whole pieces or crumbled.
