Line a half-sheet pan with parchment paper and place the prosciutto slices with some space in between them. I find it easiest to keep the paper strip on each slice and then peel it off once the prosciutto is on the baking sheet (refer to the photos above).
Bake for 11-15 minutes. The amount of time will vary depending on the thickness of your prosciutto, personal crispy preference, and how hot your oven runs (all ovens cook differently).
Remove them from the oven and transfer the slices to a wire rack to finish cooling. They'll continue to crisp up as they cool. Serve in a sandwich or crumbled on top of salad, soup, polenta, etc.
Notes
Like it super crispy? If adding additional time, keep a close eye on the prosciutto as it can quickly go from crisp to burnt.Storing crisped prosciutto. Store in an airtight container in the fridge for up to 2 weeks.How to reheat. It should retain its crispiness fairly well but if needed, place it in a skillet over medium heat for a few minutes to re-crisp.
