01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - Spread the chickpeas on a clean kitchen towel and pat them dry thoroughly — removing as much moisture as possible is key to achieving maximum crispiness.
03 - Toss the dried chickpeas with olive oil and fine sea salt until evenly coated. Arrange them in a single layer on the prepared baking sheet.
04 - Roast the chickpeas for 20 minutes, stirring halfway through, until they begin to crisp and turn lightly golden.
05 - While the chickpeas roast, whisk together the maple syrup, sriracha, toasted sesame oil, tamari, rice vinegar, and garlic powder in a small bowl until smooth.
06 - Remove the chickpeas from the oven. Immediately drizzle the glaze over them and sprinkle with sesame seeds and red pepper flakes if using. Toss to coat evenly, then use a spatula to press the coated chickpeas into rough clusters on the baking sheet.
07 - Return the pan to the oven and bake for another 8–10 minutes until the glaze is sticky and the clusters are deeply golden and crisp.
08 - Let the clusters cool completely on the baking sheet — this allows them to set and firm up. Garnish with chopped cilantro or scallions if desired. Store any leftovers in an airtight container at room temperature for up to 3 days.
