Start by cutting boneless chicken breasts into bite-sized pieces, ensuring they're uniform for even cooking.

In a bowl, combine olive oil, lemon juice, black pepper, garlic powder, and salt. Whisk until blended, then toss in your chicken pieces to coat them fully.

Thread the marinated chicken onto soaked wooden skewers or metal skewers, aiming for about 4-5 pieces per skewer.

Set your air fryer to 400°F and preheat for about 5 minutes.

Place the skewers in a single layer in the air fryer basket. Cook for 10-12 minutes, flipping halfway through.

Once done, let the skewers rest for a few minutes before serving.
