Cook your dried chickpeas to a firm texture and plunge them in a bowl of ice water. If using canned chickpeas, drain the liquid. Place the chickpeas on a paper towel to remove the excess moisture.
Preheat your air fryer on the hottest setting for a full 10 minutes. On the Ninja Foodi Pressure Cooker & Air Crisper this is the broil or grill setting. On other air fryers, use the setting that has the highest temperature.
Place the chickpeas in a bowl and spritz or drizzle with oil until lightly coated. Sprinkle the seasoning on top, I usually use ½-1 teaspoon at a time and then toss. Repeat until the desired amount of seasoning is used. You can always season more after air frying, so less is more at this stage.
Once the air fryer is preheated, place the chickpeas in the air fryer basket or tray so they are in a single layer. How many you can fit will depend on your air fryer. I can do about 1½-2 cups in the Ninja Foodi Pressure Cooker & Air Crisper. You may have to do 2 or 3 batches.
Air Fry on 375℉/190℃ for 10-12 minutes. Tossing them around a few times during the cooking process. When they are nice and crunchy, remove them from the air fryer and lay them out in a single layer on a cooling rack or on a pizza pan with holes and elevate it so air can flow all around. This will prevent them from steaming and softening.
