Preheat the oven to 400°F. Line a rimmed baking sheet with parchment paper.
Drain the chickpeas and place on a plate lined with a double layer of paper towels. Blot gently with a paper towel to remove excess moisture.
In a medium bowl, combine the chickpeas, olive oil, cumin, salt, pepper, and red chile flakes and stir to coat. Spread out on the prepared baking sheet and roast, shaking the pan occasionally, until golden brown and crispy, about 20 minutes. Serve immediately.
