In a large mixing bowl, add the chicken, olive oil, lemon zest, lemon juice and seasonings (paprika, salt, black pepper, garlic and onion powder). Mix ingredients together to thoroughly combine.
Cover bowl and refrigerate the marinade for 1 to 2 hours or overnight. Remove marinaded chicken from the fridge 15 to 20 minutes before making skewers to bring to room temperature.
Thread 5 to 6 pieces of the marinaded chicken onto the pre-soaked skewers for a total of (8) chicken skewers.
Preheat air fryer to 400F. Lightly mist the tray/insert in the air fryer basket with some cooking spray.
In (2) batches (4 skewers in each batch), air fry the chicken skewers for 6 to 7 minutes, carefully flip the skewers to the other side and air fry for an additional 6 to 7 minutes or until the chicken is fully cooked. If you have a kitchen thermometer, the internal temperature of the chicken should register at least 165F.
Transfer first batch of the cooked chicken skewers to a large plate and air fry the second batch following the same process.
As the last batch of skewers cooks, make the lemon pepper sauce. In a small mixing bowl, add the partially melted butter, lemon juice, lemon zest and seasonings (paprika, fresh cracked black pepper, salt, garlic and onion powder). Whisk ingredients together to combine.
Once all the skewers are cooked, use a pastry brush to thoroughly coat all sides of the chicken skewers in the lemon pepper sauce.
Serve lemon pepper chicken skewers as is or with your preferred side and sauce. I served the skewers with a garlic aioli sauce (link to recipe is shared in the notes). Enjoy!
