Ingredients

Scale

For the chicken:

  • 2 boneless, skinless chicken breasts (or thighs)
  • 1 cup buttermilk (or plain yogurt as alternative)
  • 1 teaspoon paprika
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon chili powder
  • 1 teaspoon black pepper
  • 1 teaspoon salt
  • 1 cup all-purpose flour
  • 2 tablespoons cornstarch
  • Oil for frying

For the sauce:

  • 1/2 cup mayonnaise
  • 1 tablespoon Dijon mustard
  • 1 teaspoon hot sauce
  • 1 teaspoon lemon juice
  • 1/2 teaspoon garlic powder
  • Salt and pepper to taste

For assembling:

  • 4 burger buns or brioche buns
  • Lettuce leaves
  • Tomato slices
  • Pickles

Instructions

  1. Slice chicken breasts in half horizontally to create thin fillets.
  2. Place in a bowl with buttermilk, paprika, garlic powder, onion powder, chili powder, salt, and pepper. Mix to coat well, cover, and marinate for 30 minutes to 4 hours.
  3. Combine flour, cornstarch, a pinch of salt, and a little paprika in a shallow dish.
  4. Remove chicken from marinade, letting excess drip off, then dredge in flour mixture. Press gently so coating sticks.
  5. Heat oil in a large skillet to 350°F (175°C). Fry chicken for 4–5 minutes per side until golden and cooked through. Drain on a wire rack or paper towel.
  6. In a bowl, whisk mayonnaise, Dijon mustard, hot sauce, lemon juice, garlic powder, salt, and pepper until smooth.
  7. Toast buns until lightly golden.
  8. Spread sauce on both halves of the buns. Add chicken fillet, lettuce, tomato, and pickles. Top with remaining bun and serve immediately.

Notes

For extra crunch, double-dip chicken by dredging in flour, dipping back into marinade, and dredging again before frying.

Adjust heat level by adding more or less chili powder or hot sauce.

The creamy sauce can be prepared in advance and refrigerated for up to three days.

For a lighter version, bake chicken fillets at 400°F (200°C) for 20–25 minutes.
