01 - Preheat oven to 400°F and line a baking sheet with parchment paper.
02 - Pat drained chickpeas thoroughly with paper towels to remove excess moisture. Remove any loose skins for maximum crispiness.
03 - Place chickpeas in a mixing bowl and toss with olive oil until evenly coated.
04 - In a small bowl, mix smoked paprika, garlic powder, onion powder, oregano, thyme, cayenne pepper, black pepper, and sea salt until well blended.
05 - Sprinkle the Cajun spice mixture over the oiled chickpeas. Toss vigorously to ensure every chickpea is evenly coated with spices.
06 - Spread seasoned chickpeas in a single layer on the prepared baking sheet, ensuring they are not overcrowded for proper crisping.
07 - Bake for 30 to 35 minutes, shaking the baking sheet halfway through cooking time. Chickpeas are done when golden brown and crispy throughout.
08 - Remove from oven and let chickpeas cool on the baking sheet for 5 to 10 minutes. They will continue to crisp up as they cool. Serve warm or at room temperature.
