Soak wooden skewers in water for 30 minutes if using. Thread 4-5 chicken cubes per skewer, leaving small gaps between pieces. Pat off excess marinade with paper towel to avoid drips.

Preheat the air fryer to 400°F for 3-5 minutes before cooking the skewers to ensure immediate searing.
Arrange skewers single layer in the air fryer basket with at least 1 inch space between to prevent steaming. Cook at 400°F for 6 minutes, then flip and cook another 4-6 minutes until internal temperature reaches 165°F.
