I’m not seeing anyone mention buttermilk. I personally don’t care for the breading made with egg. I roll my chicken in seasoned flour (salt, pepper, garlic and onion powder, chili powder) then in a bowl with buttermilk with hot sauce in it and then back in the flour one piece at a time and you’ll have a thick crunchy breading. Make sure your oil is high enough to cover most of the sides of your pieces of chicken so you’re not having to turn it a bunch. And if you put a wooden spoon in your oil and there’s some bubbles around it it’s hot enough
