Add the chicken pieces to a bowl, season with seasoning salt, mayonnaise, garlic powder, and grated parmesan. Mix to coat evenly. Allow the chicken to marinate for as little as 20 minutes, ideally 4-16 hours covered in the refrigerator.

In a bowl, combine the butter, pressed garlic, parsley, parmesan, chili crisp, and lemon juice. Press with a fork to create a compound butter. Microwave for 5 seconds to loosen it.

Thread chicken pieces onto metal or wooden skewers and set aside. Preheat an air fryer or an outdoor grill to 400ºF.

Once the air fryer is heated, add 4-7 skewers at a time, taking care not to overcrowd. Cook the chicken skewers for 6 minutes, flip, and cook for another 3 minutes.

Check the temperature of the chicken; it should have reached 150ºF. Baste the chicken and cook for 1 minute. Then flip, baste the other side, and cook for another 30-40 seconds. Check for doneness; it should read 165ºF.

Remove skewers from the air fryer, top with more parmesan or parsley, and serve warm with your favorite sides!
