01 - Whisk together buttermilk, hot sauce (if using), salt, and pepper in a large bowl. Add chicken pieces and turn to coat thoroughly. Cover and refrigerate for at least 4 hours or overnight for optimal flavor and tenderness.
02 - Combine flour, paprika, garlic powder, onion powder, cayenne pepper, salt, and black pepper in a large shallow dish. Mix well to distribute spices evenly.
03 - Take chicken pieces out of the buttermilk mixture, allowing excess liquid to drip off. Do not pat dry—the moisture helps the coating adhere.
04 - Press each chicken piece firmly into the seasoned flour mixture, coating completely and ensuring the flour adheres well to all surfaces. Place coated pieces on a wire rack.
05 - Pour oil into a large heavy skillet or deep fryer. Heat to 350°F, maintaining temperature throughout frying process for consistent results.
06 - Working in batches to avoid overcrowding, carefully place chicken pieces in hot oil. Fry for 8-12 minutes per side, turning once, until golden brown and crispy. Internal temperature must reach 165°F for safe consumption.
07 - Transfer fried chicken to a clean wire rack or paper towels to drain excess oil. Let rest for 5 minutes before serving to allow juices to redistribute.
