01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - Pat chickpeas thoroughly dry with a clean kitchen towel and remove any loose skins to enhance crispiness.
03 - In a large mixing bowl, combine chickpeas with olive oil, ground cumin, chili powder, smoked paprika, cayenne pepper if using, sea salt, and black pepper. Toss until evenly coated.
04 - Spread the seasoned chickpeas in a single layer on the prepared baking sheet.
05 - Roast for 25 to 30 minutes, shaking the pan halfway through, until the chickpeas are golden and crisp.
06 - Allow roasted chickpeas to cool slightly. Serve warm or at room temperature, optionally garnished with chopped cilantro and a squeeze of lime.
