In a bowl, combine the buttermilk and hot sauce. Add the chicken tenderloins, ensuring they are fully submerged. Cover and refrigerate for at least 1 hour (or overnight for better flavor).
In a large shallow dish, mix the flour, Cajun seasoning, paprika, garlic powder, onion powder, black pepper, and salt until well combined.
In a deep skillet or frying pan, pour in enough vegetable oil for frying (about 1 inch deep) and heat it over medium-high heat until it reaches 350°F (175°C).
Remove each chicken tender from the buttermilk marinade, allowing excess liquid to drip off. Dredge each piece in the seasoned flour mixture, making sure it’s well coated. Shake off any excess flour.
Carefully place the coated chicken tenders into the hot oil, cooking in batches to avoid overcrowding. Fry for about 4-5 minutes on each side, or until golden brown and cooked through. Use a meat thermometer to ensure the internal temperature reaches 165°F (75°C).
Using a slotted spoon, remove the chicken tenders from the oil and place them on a plate lined with paper towels to drain excess oil.
Notes
Serve with a side of dipping sauce and garnish with fresh parsley.
