Crispy Salt-and-Pepper Chicken Skin

Preheat oven to 350°. Trim meat and excess fat from chicken skin; cut into 3" pieces. Flatten, flesh side down, on a parchment-lined baking sheet. Season with salt and pepper; top with another sheet of parchment and baking sheet (to keep skin from curling). Bake until browned and crisp, about 1 hour. Remove top baking sheet and paper; let cool 10 minutes.

Do Ahead: Skin can be baked 3 hours ahead. Store airtight at room temperature.
