Start by combining the buttermilk and hot sauce in a large bowl. This mixture helps tenderize the chicken while adding flavor to every bite. Add the chicken tenders and let them soak for at least 30 minutes for the best texture.
In another large bowl, whisk together flour, cornstarch, seasoned salt, paprika, cayenne pepper, onion powder, garlic powder, and black pepper. The cornstarch helps create an extra crispy crust that stays crunchy longer. Make sure the spices are evenly mixed throughout the flour.
Remove each chicken tender from the marinade and dredge it in the seasoned flour. Dip it back into the buttermilk mixture, then coat it again in the flour mixture. This double coating creates the thick, crunchy crust Nashville chicken is famous for.
Place the coated chicken tenders on a baking sheet or wire rack. Let them rest for about 15 to 20 minutes before frying. I noticed this step really helps the breading stick better during frying.
Pour vegetable oil into a heavy skillet or Dutch oven until it’s about 2 inches deep. Heat the oil over medium-high heat until it reaches around 350°F. If a small pinch of flour sizzles immediately, the oil is ready for frying.
Carefully place a few chicken tenders into the hot oil without overcrowding the pan. Fry each side for about 2 to 3 minutes until golden brown and crispy. Transfer the cooked chicken to a wire rack so it stays crunchy.
In a heat-safe bowl, whisk together cayenne pepper, brown sugar, chili powder, garlic powder, and smoked paprika. Carefully add one cup of the hot frying oil and stir until smooth. The warm oil helps bloom the spices and create that classic fiery glaze.
Brush the spicy glaze generously over the hot fried chicken tenders. Make sure every piece gets coated evenly for maximum flavor. The sauce should soak slightly into the crispy crust while still keeping the chicken crunchy.
Place the chicken tenders on slices of soft white bread and top with pickles. The bread absorbs some of the spicy oil while the pickles add freshness and crunch. Serve immediately while the chicken is hot and crispy.
