Pour the vegetable oil in a skillet until it is about ¾ inch deep. Heat to 350 degrees.
Season the chicken thighs and drumsticks with Dimply's Cajun Chicken Meat rub.
Prepare the wet ingredients by combining the buttermilk, hot sauce, and egg in a shallow dish. Whisk together until well combined.
Prepare the breading by combining the flour, cornstarch, onion powder, garlic powder, oregano, basil, and some more dimply's cajun chicken seasoning in a shallow dish. Mix it thoroughly.
Dip each piece of seasoned chicken into the wet ingredients. Shake it gently to remove the excess. Place it in the breading mix and coat thoroughly. Tap off the excess.
Place the breaded chicken into the 350 degree oil. Fry 3 or 4 pieces at a time. The chicken will drop the temperature of the oil so keep it at about 325 degrees. Fry each piece for 14 minutes, turning each piece over about every 2 minutes. Set a timer to make it easy.
Remove from the oil and place on paper towels. Let them rest for at least 10 minutes before serving so no one burns their mouth with hot oil.
