Ingredients

Scale

For the Chicken:

  • 2 boneless, skinless chicken breasts (cut in half for 4 fillets) or 4 boneless chicken thighs
  • 1 cup buttermilk
  • 2 tablespoons hot sauce (e.g., Frank’s RedHot or Sriracha)
  • 1 teaspoon salt
  • 1 teaspoon black pepper

For the Breading:

  • 1 cup all-purpose flour
  • ½ cup cornstarch (for extra crispiness)
  • 1 tablespoon cayenne pepper (adjust to spice preference)
  • 1 teaspoon smoked paprika
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • ½ teaspoon black pepper
  • ½ teaspoon salt

For Frying:

  • 2 cups vegetable oil (for deep frying) or cooking spray (for air frying/baking)

For the Spicy Sauce:

  • ½ cup mayonnaise
  • 1 tablespoon hot sauce
  • 1 teaspoon honey (optional, for a slight sweetness)
  • ½ teaspoon garlic powder
  • ½ teaspoon smoked paprika

For Assembly:

  • 4 brioche or potato buns (toasted)
  • ½ cup pickles (sliced)
  • ½ cup shredded lettuce (optional)
  • ½ cup coleslaw (optional)

Instructions

  • Marinate the Chicken:

    • In a bowl, mix buttermilk, hot sauce, salt, and black pepper.
    • Submerge the chicken in the marinade, cover, and refrigerate for at least 1 hour (or overnight for best results).
  • Prepare the Breading:

    • In a shallow dish, whisk together the flour, cornstarch, cayenne pepper, smoked paprika, garlic powder, onion powder, black pepper, and salt.
  • Coat the Chicken:

    • Remove the chicken from the marinade, letting excess liquid drip off.
    • Dredge each piece in the flour mixture, pressing firmly to ensure a thick, even coating.
  • Cook the Chicken:

    • Deep-Frying Method:
      • Heat oil in a deep skillet or fryer to 350°F (175°C).
      • Fry the chicken for 5-7 minutes per side until golden brown and crispy.
      • Drain on a wire rack (not paper towels) to maintain crispiness.
    • Air-Frying Method:
      • Preheat air fryer to 375°F (190°C).
      • Spray the chicken with cooking spray and air-fry for 15-18 minutes, flipping halfway.
    • Oven-Baking Method:
      • Preheat oven to 425°F (220°C).
      • Place chicken on a wire rack over a baking sheet, lightly spray with oil, and bake for 25-30 minutes, flipping halfway.
  • Make the Spicy Sauce:

    • In a small bowl, whisk together mayonnaise, hot sauce, honey (if using), garlic powder, and smoked paprika.
  • Assemble the Sandwich:

    • Toast the buns for extra flavor.
    • Spread a layer of spicy sauce on the bottom bun.
    • Place the crispy chicken fillet on top.
    • Add pickles, shredded lettuce, or coleslaw.
    • Spread extra sauce on the top bun, then place it on top of the sandwich.
  • Serve Immediately with fries, coleslaw, or your favorite side!

Notes

  • Adjust spice levels by increasing or decreasing cayenne pepper and hot sauce.
  • For extra crunch, double coat the chicken by repeating the breading process.
  • Pair with cooling sauces like ranch or garlic aioli if you prefer a balanced heat.
  • Reheat leftovers in an oven or air fryer at 375°F for 5 minutes to maintain crispiness.
