In a bowl, mix the chicken legs with all the ingredients except for the olive oil for basting. Stir well to coat evenly.
Let the chicken marinate for at least 30 minutes, but for the best flavor, marinate for 1 hour.
Place the chicken legs in a single layer in the air fryer basket. Spoon the leftover marinade over them and air fry at 200°C (400°F) for 10 minutes.
Then, baste the chicken with olive oil.
Flip the chicken legs and baste them with olive oil. Air fry at 200°C (400°F) for another 5 minutes, until fully cooked and golden brown.
Remove from the air fryer and serve hot.
