01 - Set oven to 400°F (200°C) and allow it to fully preheat before beginning preparation.
02 - Using a clean kitchen towel or paper towels, gently pat chickpeas dry, eliminating as much surface moisture as possible for ideal crispiness.
03 - Place chickpeas in a large mixing bowl and toss thoroughly with olive oil until evenly coated.
04 - Add smoked paprika, garlic powder, chili powder, ground cumin, sea salt, black pepper, and optional cayenne. Mix until chickpeas are uniformly covered with spice blend.
05 - Spread seasoned chickpeas in a single, even layer on a baking sheet lined with parchment paper to prevent sticking.
06 - Place baking sheet in preheated oven and roast chickpeas for 30 to 35 minutes, shaking the pan or stirring every 10 minutes to ensure even browning. Remove when golden and crisp.
07 - Allow roasted chickpeas to cool completely on the baking sheet before consuming to ensure maximum crunch.
