01 - Preheat the oven to 400°F and line a baking sheet with parchment paper.
02 - Pat the chickpeas very dry with a clean kitchen towel, removing any loose skins for extra crispiness.
03 - In a bowl, toss the chickpeas with olive oil until evenly coated.
04 - Add garlic powder, smoked paprika, chili powder, cumin, salt, black pepper, and cayenne (if using). Toss until well mixed.
05 - Spread the chickpeas in a single layer on the prepared baking sheet.
06 - Roast for 25–30 minutes, shaking the pan halfway through, until golden brown and crispy.
07 - Remove from the oven and let cool for 10 minutes. They will crisp up further as they cool. Enjoy immediately or store in an airtight container for up to 3 days.
