Ingredients

Scale

For the Brine:

  • 1/2 cup mayonnaise
  • 2 tbsp Dijon mustard
  • 1 tbsp lemon juice
  • 2 cloves garlic, minced
  • 1 tsp smoked paprika
  • 1 tsp salt
  • 1/2 tsp black pepper

For the Chicken:

  • 2 large boneless, skinless chicken breasts
  • 1 cup buttermilk
  • 1 1/2 cups all-purpose flour
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1 tsp smoked paprika
  • 1/2 tsp cayenne pepper (optional)
  • Salt and pepper to taste
  • Vegetable oil for frying

For Assembly:

  • 4 sandwich buns, toasted
  • Leaf lettuce
  • Tomato slices
  • Dill pickle slices
  • Additional Dijon mayo sauce (mayonnaise mixed with Dijon mustard)


Instructions

  1. Make the Brine: In a bowl, whisk together mayonnaise, Dijon mustard, lemon juice, minced garlic, smoked paprika, salt, and black pepper to create the flavorful brine that will tenderize and season the chicken.
  2. Prepare the Chicken: Flatten the chicken breasts to an even thickness using a meat mallet or rolling pin to ensure uniform cooking. Coat each piece thoroughly with the Dijon mayo brine, then cover and refrigerate for at least 1 hour, ideally 3–4 hours, to allow the flavors to penetrate deeply.
  3. Heat the Oil: Preheat vegetable oil in a deep skillet or fryer to 350°F (175°C), ensuring the oil is hot enough to create a crispy crust without absorbing excess grease.
  4. Prepare the Flour Coating: In a shallow dish, combine all-purpose flour with garlic powder, onion powder, smoked paprika, cayenne pepper (if using), salt, and pepper. Mix well to evenly distribute the spices.
  5. Coat the Chicken: Remove the chicken breasts from the brine and dip each into the buttermilk, then dredge thoroughly in the seasoned flour mixture, pressing the flour onto the surface to ensure a thick, crispy coating.
  6. Fry the Chicken: Carefully fry the coated chicken breasts in the hot oil for 5 to 7 minutes on each side, or until golden brown and fully cooked through, reaching an internal temperature of 165°F (74°C).
  7. Drain the Chicken: Remove the fried chicken breasts from the oil and place them on paper towels to drain excess oil, maintaining crispiness.
  8. Assemble the Sandwich: Spread additional Dijon mayo sauce on the toasted sandwich buns. Layer leaf lettuce, a crispy chicken breast, tomato slices, and dill pickle slices on the bottom buns. Top with the other half of the bun to complete the sandwich.

Notes

  • For extra flavor, brine the chicken overnight.
  • Use a thermometer to ensure the oil is at a consistent 350°F for perfect frying.
  • Adjust cayenne pepper amount to control the spice level.
  • May substitute sandwich buns with brioche buns for a richer taste.
  • Leftover sauce can be refrigerated for up to 3 days.
