Preheat the oven to 400°F/200°C. Drain the chickpeas and rinse with cold water. Place them in a large baking dish or a with parchment paper lined baking tray and bake for 15 minutes. → Use a large enough dish so that the chickpeas have place in one single layer and don't stack on each other. This is important to make them crispy.
Take them out of the oven, mix with the olive oil and spices, and bake for another 15 minutes until golden and crispy.
Turn off the oven, open the door ajar (stick a wooden spoon between the door and oven), and let the chickpeas cool down in the oven. → Makes them crispier!
Notes
Serve them as a healthy snack, with salad, or in wraps.
