In a large bowl, combine chicken with buttermilk, pickle juice, and salt.
Marinate 30 mins at room temperature. You can also marinate, covered, in the fridge for a couple/few hours.
Drain marinade and set chicken aside.
In a gallon sized ziplock baggie, combine panko, flour, salt, pepper, paprika, and garlic powder.*
Place drained chicken into baggie with panko mixture, seal, and gently shake until chicken pieces are fully coated. Set aside.
Hit “ON” on the air fryer. Then hit “PRE-HEAT”. Set the temperature to 400 degrees F and set the timer to 8 minutes. Hit “START”. The air fryer will beep at you when it’s finished preheating.
Open up the air fryer and spray the basket with cooking spray. Place in the chicken nuggets, work with about 12 at a time, so you don’t over crowd them. Close the air fryer. It will beep at you when it’s finished cooking. Repeat with remaining chicken nuggets.
Taste and re-season, if necessary and serve with your favorite dipping sauce!
*You could also do this is another bowl as shown in the video, if you like.
