Creating the perfect Nashville Hot Chicken Sandwiches is easy if you follow these steps:

1. Marinate the Chicken: In a bowl, mix buttermilk and hot sauce. Add chicken thighs, ensuring they are well coated. Cover and refrigerate for at least 30 minutes, or up to overnight for maximum flavor.
2. Prepare the Coating: In a large bowl, mix flour, paprika, cayenne pepper, garlic powder, onion powder, salt, and black pepper.
3. Heat the Oil: In a large skillet, heat vegetable oil over medium-high heat until it reaches 350°F (175°C).
4. Coat the Chicken: Remove chicken from the buttermilk mixture, allowing excess to drip off. Dredge each piece in the flour mixture, ensuring a thick, even coating.
5. Fry the Chicken: Carefully place the coated chicken in the hot oil. Fry for about 6-8 minutes on each side, or until golden brown and cooked through. Use a meat thermometer to ensure the internal temperature reaches 165°F (74°C).
6. Drain the Chicken: Once cooked, transfer the chicken to a wire rack or paper towels to drain excess oil.
7. Prepare the Spicy Oil: In a small bowl, mix additional cayenne pepper with 2-3 tablespoons of the frying oil. Brush this mixture generously over the fried chicken for added heat.
8. Assemble the Sandwiches: Place a piece of chicken on the bottom half of each bun. Top with dill pickles and coleslaw if desired. Add the top bun to complete the sandwich.
9. Serve: Serve the sandwiches warm, with additional hot sauce on the side for those who crave more heat.

By following these simple steps, you will create Nashville Hot Chicken Sandwiches that are crispy, spicy, and utterly delicious!
