Buttermilk-marinated country fried chicken with a perfectly seasoned crust is a timeless Southern family tradition. Each piece delivers juicy, high protein goodness that's worth every crispy bite.
Place the chicken pieces in a large bowl and pour over the buttermilk, ensuring all chicken is coated. Cover and marinate in the refrigerator for at least 30 minutes, preferably 2-4 hours for best flavor and tenderness.
In a separate shallow dish, combine the flour, salt, black pepper, garlic powder, paprika, onion powder, and cayenne pepper. Whisk well to distribute the seasonings evenly throughout the flour.
Beat the eggs in a separate bowl. Remove chicken from buttermilk, letting excess drip off. Dredge each piece first in the seasoned flour, then dip in beaten egg, then again in seasoned flour for a double coating. Shake off excess flour.
Heat peanut oil in a large cast iron skillet to 350°F (medium-high heat). Fry chicken in batches without crowding the pan. Adjust heat as needed to maintain temperature, turning pieces occasionally for even browning. Fry for 14-18 minutes until golden brown and internal temperature reaches 165°F.
Transfer chicken to a wire rack set over a baking sheet to drain excess oil. Let rest 5 minutes before serving for juiciest texture.
