Marinate the chicken breasts in pickle juice and buttermilk for at least 2–4 hours.
In a bowl, combine all-purpose flour with paprika, garlic powder, onion powder, black pepper, and salt.
Remove the chicken from the marinade and coat it evenly in the seasoned flour mixture.
Let the coated chicken rest for 5–10 minutes to help the breading adhere.
Heat oil to 175°C (350°F) and fry the chicken until golden brown and fully cooked.
Drain on a wire rack to keep the coating crispy.
Serve on a toasted bun with pickles, lettuce, and your favorite sauce, or enjoy as crispy fried chicken.
