Pound the chicken breasts to an even thickness of about 1/2 inch. Place them in a bowl and pour the pickle juice over the chicken. Cover and refrigerate for 30 minutes to 1 hour.
Prepare the Breading and Dredging:
Mix the Wet Batter:
In a shallow dish, whisk together the milk and egg.
Prepare the Dry Coating:
In another shallow dish, combine the flour, powdered sugar, paprika, garlic powder, salt, black pepper, and cayenne pepper.
Bread the Chicken:
Dredge the Chicken:
Remove the chicken from the pickle juice and pat dry with paper towels. Dip each piece into the dry mixture, then into the wet mixture, and back into the dry mixture, pressing to coat thoroughly.
Fry the Chicken:
Heat the Oil:
In a large skillet or deep fryer, heat about 1 inch of oil to 350°F (175°C).
Fry the Chicken:
Fry the chicken in batches for 4-5 minutes per side, or until golden brown and cooked through (internal temperature of 165°F/74°C). Drain on a wire rack or paper towels.
Assemble the Sandwich:
Toast the Buns:
Spread butter on the inside of each bun and toast in a skillet until golden.
Build the Sandwich:
Place a few pickle slices on the bottom bun, add a piece of crispy chicken, and top with the upper bun. Add optional toppings if desired.
Serve:
Enjoy Hot:
Serve immediately with waffle fries or a side salad.
Notes
For an authentic flavor, peanut oil is recommended for frying.
The powdered sugar in the breading adds a touch of sweetness, mimicking the Chick-fil-A signature taste.
Marinating longer than 1 hour may result in overly salty chicken.
