01 - Preheat your oven to 400°F. Line a baking sheet with parchment paper.
02 - Pat the chickpeas dry thoroughly with a clean kitchen towel or paper towels. Removing excess moisture is key for crispiness.
03 - In a large bowl, toss the chickpeas with olive oil, smoked paprika, Cajun seasoning, garlic powder, onion powder, cayenne pepper, salt, and pepper until evenly coated.
04 - Spread the chickpeas in a single layer on the prepared baking sheet.
05 - Roast for 35–40 minutes, shaking or stirring the pan halfway through, until crispy and golden brown.
06 - Remove from the oven and let cool for 10 minutes. The chickpeas will continue to crisp up as they cool. Serve immediately, or store in an airtight container at room temperature for up to 3 days.
