In a large bowl (or you can use a zip lock bag for this) massage the chicken legs with the marinade and leave it in the fridge for 30 minutes or 1-2 hours if you have more time.
Preheat air fryer to 375 F according to manufacturer instructions.
Once the air fryer is preheated, transfer the chicken into the basket and air fry for 10 minutes (discard the leftover marinade or reheat in a pan until gently simmering to drizzle on top when serving).
Flip the chicken for the last 10 minutes. Total air frying time 20 minutes. Chicken should be darkened, browned and very crisp on the outside.
