01 - Preheat your oven to 400°F. Line a baking sheet with parchment paper to prevent sticking.
02 - Pat the drained and rinsed chickpeas very dry using a clean kitchen towel or paper towels. This step is crucial for achieving maximum crispiness.
03 - In a large mixing bowl, toss the dried chickpeas with the olive oil until each chickpea is evenly coated.
04 - Add the smoked paprika, garlic powder, onion powder, oregano, thyme, cayenne pepper, black pepper, and sea salt to the bowl. Toss well to ensure all chickpeas are thoroughly coated with the spice blend.
05 - Spread the seasoned chickpeas in a single layer on the prepared baking sheet. Avoid overcrowding the pan for optimal crisping.
06 - Roast for 35–40 minutes, shaking the pan or stirring the chickpeas once halfway through the cooking time. Continue roasting until they are golden brown and crisp to the touch.
07 - Allow the roasted chickpeas to cool on the baking sheet for 10 minutes. They will continue to crisp as they cool down.
08 - Serve the Cajun spiced roasted chickpeas immediately as a snack or salad topping. For storage, transfer them to an airtight container and keep at room temperature for up to 3 days.
