Ingredients

Chicken and Marinade

  • 2 boneless, skinless chicken breasts
  • 1 cup buttermilk

Breading Mixture

  • 1 cup all-purpose flour
  • 1 tsp salt
  • 1 tsp black pepper
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1 tsp paprika
  • 1/4 tsp cayenne pepper

Batter and Coating

  • 1 large egg
  • 1 tbsp water
  • 1 cup breadcrumbs
  • Vegetable oil for frying

Sandwich Components

  • 4 hamburger buns
  • 1/4 cup mayonnaise
  • 1 tbsp Dijon mustard
  • 1 tbsp lemon juice
  • 1 tsp lemon zest
  • Shredded lettuce
  • Sliced tomato
  • Chopped fresh parsley

Instructions

  1. Prep the chicken: Place the chicken breasts on a cutting board and carefully slice them horizontally into thinner pieces to ensure faster cooking and more surface area for the crispy coating.
  2. Marinate in buttermilk: Place the sliced chicken pieces in a bowl or zip-top bag and pour the buttermilk over them. Let them marinate for at least 20–30 minutes or up to a few hours in the refrigerator to tenderize and flavor the chicken.
  3. Season and set up your dredging station: In a shallow bowl, combine flour, salt, black pepper, garlic powder, onion powder, paprika, and cayenne pepper. In a separate bowl, whisk together the egg and water until smooth. Place breadcrumbs in a third bowl for coating.
  4. Coat the chicken: Remove chicken from buttermilk, allowing excess to drip off. Dip each piece into the flour mixture to coat evenly, then into the egg wash, and finally press firmly into the breadcrumbs to ensure a thick, crispy crust.
  5. Heat the oil: Pour vegetable oil into a large skillet to about 1/4 inch depth and heat over medium-high heat until shimmering. Test readiness by dropping in a pinch of flour; if it sizzles immediately, the oil is ready.
  6. Fry the chicken: Carefully place the coated chicken pieces in the hot oil, spacing them apart to avoid steaming. Fry for 4–5 minutes on each side until golden brown and cooked through, reaching an internal temperature of 165°F.
  7. Drain and rest: Transfer fried chicken to a paper towel-lined plate to drain excess oil. Let rest for a couple of minutes to maintain crispiness.
  8. Toast the buns: While the chicken rests, lightly toast the hamburger buns in a dry skillet or toaster for added crunch and to prevent sogginess.
  9. Make the sauce: In a small bowl, mix mayonnaise, Dijon mustard, lemon juice, and lemon zest until smooth and creamy. Adjust lemon flavor to taste if desired.
  10. Assemble your masterpiece: Spread the lemon-mustard sauce generously on the bottom half of each bun. Layer a crispy chicken piece, then shredded lettuce, tomato slices, and a sprinkle of fresh parsley for color and freshness.
  11. Finish and serve: Top the sandwich with the bun tops and serve immediately while warm and crispy for the best texture and flavor experience.

Notes

  • Slice the chicken thin to ensure even cooking and extra crispy texture.
  • For a lighter alternative, bake the coated chicken at 400°F for 20–25 minutes, flipping halfway through.
  • Best served fresh, but leftovers can be reheated in the oven to maintain crispiness.
