Preheat the air fryer to 400°F, air fryer setting.
Meanwhile, in a small bowl mix together the olive oil, lemon juice, Dijon mustard, garlic, salt, and pepper. Then toss the wings in the coating.
Place about half of the chicken wings in the fry basket and insert it into the air fryer. (You do not want the chicken wings to be crowded)
Cook until the skin is browned and crisp, 26 to 28 minutes. I usually set the timer for 12 minutes and then open it up, flip the chicken wings, and set it for another 12 minutes. This is a great way to make sure that all sides are cooked, and not burnt on one side.
Plate and serve, repeat with all the wings, until you are done with the batch.
