01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - Pat the chickpeas dry thoroughly with a clean kitchen towel or paper towels, removing any loose skins to ensure crispiness.
03 - In a mixing bowl, combine chickpeas with olive oil, cumin, smoked paprika, garlic powder, cayenne pepper if desired, sea salt, and black pepper, tossing until evenly coated.
04 - Spread the seasoned chickpeas in a single layer on the prepared baking sheet.
05 - Roast in the preheated oven for 25 to 30 minutes, stirring or shaking the pan halfway through, until chickpeas are golden and crisp.
06 - Allow chickpeas to cool slightly before serving; they will continue to crisp as they cool.
