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, salt, and black pepper in a large shallow dish. Mix well to distribute spices evenly.
03 - Take chicken out of the buttermilk mixture, allowing excess liquid to drip off naturally. Do not pat dry—remaining marinade helps flour adhere.
04 - Press each chicken piece firmly into the seasoned flour mixture, coating completely and pressing gently to ensure the coating sticks well. 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 for optimal crispiness.
06 - Working in batches to avoid overcrowding, carefully lower chicken pieces into hot oil. Fry for 8-12 minutes per side, turning once, until deep golden brown and crispy. Internal temperature must reach 165°F for safe consumption.
07 - Transfer cooked 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.
