  • ½ teaspoon garlic powder
  • ½ teaspoon smoked paprika
  • For Assembly:
  • 4 brioche buns
  • Butter for toasting buns
  • 8 dill pickle slices
  • 4 lettuce leaves

Instructions
 

  • Step 1: Prepare the Chicken
  • If the chicken breasts are thick, slice them in half horizontally or pound them with a meat mallet for even cooking.
  • In a bowl, mix buttermilk, salt, black pepper, paprika, garlic powder, onion powder, and cayenne.
  • Submerge the chicken in the buttermilk mixture and let it marinate for at least 1 hour (or overnight for best results).
  • Step 2: Prepare the Breading
  • In a shallow dish, whisk together flour, cornstarch, salt, black pepper, paprika, garlic powder, onion powder, and cayenne.
  • In another bowl, whisk together the egg and 2 tablespoons of buttermilk.
  • Step 3: Coat the Chicken
  • Remove the chicken from the marinade, letting excess buttermilk drip off.
  • Dredge the chicken in the flour mixture, then dip it into the egg mixture, and coat it again in the flour mixture, pressing firmly for a thick, crispy crust.
  • Place coated chicken on a wire rack and let it rest for 10 minutes.
  • Step 4: Fry the Chicken
  • Heat oil in a deep fryer or large skillet to 350°F (175°C).
  • Fry each chicken breast for 3-4 minutes per side or until golden brown and cooked through (internal temperature of 165°F (74°C)).
  • Transfer to a wire rack to drain excess oil.
  • Step 5: Make the Sauce
  • In a small bowl, mix mayonnaise, Dijon mustard, honey, lemon juice, garlic powder, and smoked paprika.
  • Step 6: Assemble the Sandwich
  • Butter the brioche buns and toast them in a skillet until golden.
  • Spread the sauce on both halves of the bun.
  • Add lettuce, pickles, and the crispy chicken breast.
  • Top with the other half of the bun and serve hot!

Notes

For extra crispiness, double-dip the chicken in the flour mixture.
Air fryer option: Cook at 375°F (190°C) for 12-15 minutes, flipping halfway through.
Spicy option: Add hot sauce to the buttermilk marinade and increase cayenne in the breading.
