Marinate for Flavor: In a bowl, combine the chicken tenders and pickle juice. Cover and refrigerate for at least 30 minutes, or up to overnight for maximum flavor.
Egg Wash Prep: Drain the pickle juice from the chicken. In a separate bowl, whisk together the egg and milk. Add the chicken to this mixture and let it sit while preparing the breading.
Make the Breading: In a large ziplock bag, combine the flour, powdered sugar, paprika, cayenne, black pepper, and salt. Seal the bag and shake to mix thoroughly.
Coat the Chicken: Remove each tender from the egg mixture and place it into the flour bag. Seal and shake until all tenders are evenly coated.
Heat the Oil: Pour oil into a skillet over medium heat. Once the oil is hot, add chicken tenders in batches. Fry each batch for 3 to 5 minutes or until golden brown and fully cooked through.
Drain and Serve: Transfer the tenders to a paper towel-lined plate to drain excess oil. Serve hot with dipping sauces like honey mustard, BBQ, or Chick-Fil-A sauce.
