Before You Begin
Preheat and prepare your cookware as needed. Cooking times and results may vary depending on your equipment and ingredients. Use caution when working with hot oil and raw poultry. Wash hands and surfaces after handling raw chicken.
Marinate Chicken
Combine buttermilk, hot sauce, salt, and pepper. Add chicken and marinate at least 1 hour or overnight in the refrigerator.
Prepare Breading
In a bowl, whisk together flour, cornstarch, baking powder, salt, garlic powder, onion powder, paprika, pepper, and cayenne.
Double Dredge
Remove chicken from marinade and allow excess to drip off.
Coat in flour mixture, dip back into marinade, then coat again in flour mixture, pressing gently so coating adheres.
Heat Oil
Heat oil in a heavy skillet to 350°F (175°C). Use a thermometer for accuracy.
Fry Chicken Safely
Fry 1–2 cutlets at a time, turning once during cooking, until the coating is golden brown and the internal temperature reaches 165°F (74°C) when checked with a thermometer. Cooking time may vary depending on cutlet thickness and oil temperature. Transfer to a wire rack.
Make Gravy
Carefully pour off excess oil, leaving 2 tablespoons drippings.
Whisk in flour and cook 1 minute.
Slowly whisk in milk and simmer until thickened. Season with salt and pepper.
Serve
Serve chicken hot topped with warm gravy.
