01 - Preheat your oven to 400 degrees Fahrenheit. Line a baking sheet with parchment paper to prevent sticking.
02 - Thoroughly pat the drained and rinsed chickpeas very dry using a clean kitchen towel or paper towels. Removing excess moisture is crucial for achieving maximum crispiness during roasting.
03 - In a large mixing bowl, combine the dried chickpeas with olive oil. Toss until all the chickpeas are evenly coated.
04 - Add the smoked paprika, garlic powder, onion powder, dried oregano, dried thyme, cayenne pepper, ground black pepper, and sea salt to the bowl. Toss vigorously until the chickpeas are uniformly coated with the aromatic spice blend.
05 - Spread the seasoned chickpeas in a single, even layer onto the prepared baking sheet. Ensure they are not overcrowded to facilitate even roasting and crisping.
06 - Roast in the preheated oven for 35 to 40 minutes. Gently shake the pan or stir the chickpeas once halfway through the cooking time, until they achieve a golden-brown hue and a delightful crisp texture.
07 - Once roasted, remove the baking sheet from the oven and allow the chickpeas to cool on the sheet for approximately 10 minutes. They will continue to crisp up as they cool.
08 - Serve the Cajun spiced roasted chickpeas immediately as a flavorful snack or crunchy salad topper. For storage, transfer any leftovers to an airtight container and keep at room temperature for up to three days.
