01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - Pat the chickpeas thoroughly dry with a clean kitchen towel. Remove any loose skins for maximum crispiness.
03 - In a large mixing bowl, combine the olive oil, minced garlic, smoked paprika, chili powder, ground cumin, sea salt, black pepper, and cayenne pepper if using.
04 - Add the dried chickpeas to the spice mixture and toss thoroughly until evenly coated.
05 - Sprinkle chickpea flour (or cornstarch) over the coated chickpeas and toss again until they are evenly dusted and begin to clump together.
06 - Spread the chickpeas on the prepared baking sheet in small clusters, pressing them gently together so they hold their shape.
07 - Roast for 30–35 minutes, flipping the clusters halfway through, until golden brown and crispy.
08 - Let cool for 10 minutes on the baking sheet—the clusters will continue to crisp as they cool. Serve as a snack or salad topper.
