01 - Set oven to 400°F and line a baking sheet with parchment paper.
02 - Pat chickpeas thoroughly dry with a towel or paper towels to eliminate surface moisture.
03 - Transfer chickpeas to a mixing bowl. Drizzle with olive oil, then add garlic powder, smoked paprika, chili flakes, ground cumin, sea salt, and black pepper. Toss until evenly coated.
04 - Spread seasoned chickpeas in a single layer on the lined baking sheet.
05 - Roast for 25 to 30 minutes, shaking the pan halfway through, until chickpeas are golden and crisp.
06 - Allow chickpeas to cool on the baking sheet for 10 minutes; they will become crunchier as they cool.
