Wash and pat dry the chicken pieces using paper towels.
Place the chicken in a bowl and add buttermilk, one tablespoon of Cajun seasoning, and a little salt.
Mix well, cover, and refrigerate for at least 30 minutes.
In another bowl, combine all-purpose flour with the remaining Cajun seasoning and black pepper.
Remove the chicken from the buttermilk and coat each piece thoroughly with the seasoned flour.
Heat oil in a deep frying pan over medium heat.
Carefully add the chicken pieces and fry until golden brown and crispy.
Turn occasionally to ensure even cooking.
Make sure the chicken reaches an internal temperature of 74°C (165°F).
Remove the chicken and place it on paper towels to drain excess oil.
Serve hot with Cajun sauce, mayonnaise, coleslaw, or French fries.
