Heat your oven to 375 degrees F and line a baking sheet with parchment paper.
In a bowl, toss the chickpeas in the olive oil, then spread them onto your baking sheet in a single, even layer.
Roast for 15 minutes, then remove from the oven.
In a small bowl, mix the garlic powder, onion powder, paprika, salt, and pepper until thoroughly combined.
Sprinkle the spice mixture over the par-roasted chickpeas, then give the pan a shake to toss the chickpeas and coat them all over.
Return the chickpeas to the oven, and roast for another 15-20 minutes, or until crispy and browned. Set aside to cool.
