Marinate the Chicken: Place chicken pieces in a bowl and pour buttermilk over them, ensuring all pieces are fully submerged. Cover and refrigerate for at least 2 hours or up to overnight for maximum tenderness and flavor.
Prepare the Flour Mixture: In a shallow dish, whisk together flour, paprika, garlic powder, onion powder, black pepper, salt, and cayenne pepper if using. This creates a flavorful seasoning blend that coats the chicken evenly.
Set Up the Breading Station: Beat the eggs in another shallow dish. Line up your buttermilk bowl, beaten egg dish, and flour mixture for efficient breading.
Coat the Chicken: Remove chicken pieces from buttermilk one at a time, shaking off excess liquid. Dip into the beaten egg, then dredge thoroughly in the flour mixture, pressing gently so the coating adheres. Set coated pieces on a plate and let them rest for 10 minutes so the coating sets.
Heat the Oil: Pour vegetable oil into a deep skillet or Dutch oven and heat to 350 degrees Fahrenheit. Use a thermometer to ensure the oil reaches the correct temperature for crispy, golden results.
Fry the Chicken: Carefully place coated chicken pieces into the hot oil, working in batches to avoid overcrowding. Fry for 12 to 15 minutes, turning halfway through, until the coating is deep golden brown and the internal temperature reaches 165 degrees Fahrenheit.
Drain and Rest: Transfer fried chicken to a paper towel-lined plate to drain excess oil. This keeps the chicken crispy while any remaining moisture is absorbed.
Create the Base: Arrange shredded lettuce on a serving plate to create a fresh foundation for your fried chicken.
Layer the Main Components: Place the golden fried chicken pieces in the center of the plate, positioning them prominently as the star of the dish.
Add Crispy Fries: Arrange French fries on the side of the plate, creating nice contrast with the lettuce and chicken.
Garnish with Vegetables: Add sliced tomato and red onion around the plate for freshness, color, and a light, tangy element that balances the richness of the fried chicken.
