01 - Preheat the oven to 400°F and line a baking sheet with parchment paper.
02 - Pat the chickpeas thoroughly dry with paper towels, removing any loose skins for enhanced crispiness.
03 - Place the chickpeas in a large mixing bowl and toss with olive oil until evenly coated.
04 - Sprinkle ground cumin, smoked paprika, cayenne pepper, garlic powder, sea salt, and black pepper over the chickpeas; toss again to ensure even coating.
05 - Spread the chickpeas in a single layer on the prepared baking sheet.
06 - Roast in the preheated oven for 30 to 35 minutes, shaking the baking sheet or stirring halfway through to promote even crisping, until golden and crunchy.
07 - Allow the chickpeas to cool slightly before serving. Store any leftovers in an airtight container at room temperature.
