In a medium bowl, combine the chicken pieces with buttermilk and let them marinate for at least 30 minutes.
In another bowl, mix together the Cajun seasoning, flour, cornmeal, garlic powder, paprika, cayenne pepper, salt, and pepper until well combined.
Heat vegetable oil in a deep skillet or frying pan over medium heat until it reaches 350°F (175°C).
Remove the chicken from the buttermilk, allowing excess to drip off, and dredge each piece in the flour mixture until fully coated.
Carefully place the coated chicken pieces in the hot oil, ensuring not to overcrowd the pan. Fry them for about 4-5 minutes or until golden brown and fully cooked, flipping halfway through.
Once cooked, transfer the chicken bites to a paper towel-lined plate to drain excess oil.
Garnish with chopped fresh parsley before serving.
Notes
Serve with a side of dipping sauce for extra flavor.
