In a large mixing bowl, combine the pickle juice and buttermilk. Add your chicken tenders to the bowl, and make sure they are completely covered. Cover the bowl with a lid or plastic wrap and refrigerate for 1-2 hours.
After brining the chicken, drain the brine from the bowl and toss the chicken tenders in olive oil. Then add the ranch seasoning, parmesan, and black pepper. Toss until the chicken is fully coated.
Spray the air fryer basket with olive oil spray or line it with Air fryer parchment paper for easy cleanup. Place the seasoned chicken tenders on top and spray with olive oil. Then air fry for 8 minutes, flip and cook for another 6 minutes or until the internal temperature reaches 165ā.
Top with ranch dressing and chopped cilantro before serving.
