Step 1: Marinate the Chicken
In a large bowl, combine chicken tenders, pickle juice, garlic powder, and onion powder.
Cover and refrigerate for at least 1 hour, or up to 4 hours for extra flavor.
Remove chicken from the brine and pat dry with paper towels.
Step 2: Prepare the Coating
In one bowl, whisk together flour, cornstarch, paprika, salt, black pepper, and cayenne.
In another bowl, whisk together eggs and buttermilk.
Step 3: Coat the Chicken
Dip each chicken tender into the flour mixture, then into the egg mixture, and back into the flour mixture (for a double coating).
Step 4: Cook the Chicken
For Frying:
Heat oil in a deep skillet to 350°F (175°C).
Fry chicken in batches for 4-5 minutes per side until golden brown and crispy.
Drain on a paper towel-lined plate.
For Baking:
Preheat oven to 425°F (220°C).
Place coated tenders on a greased baking sheet, spray lightly with cooking spray, and bake for 20-25 minutes, flipping halfway.
For Air Frying:
Preheat air fryer to 400°F (200°C).
Spray tenders lightly with oil and air fry for 12-14 minutes, flipping halfway.
