Make a restaurant-quality crispy chicken burger using a double-dredge method for maximum crunch, paired with a simple, balanced sweet and tangy homemade honey mustard sauce.
Prepare the Chicken: Pound the chicken halves to an even 1/2-inch thickness. Set up a three-stage breading station. In the first shallow dish, whisk the eggs and buttermilk together. In the second dish, combine the flour, cornstarch, paprika, garlic powder, onion powder, salt, and pepper. In the third dish, place the panko breadcrumbs.
Double-Dredge for Crispiness: Dredge each chicken piece first in the flour mixture, shaking off excess. Dip completely into the wet egg/buttermilk mixture. Return the chicken to the flour mixture, pressing firmly to coat completely. Finally, press the chicken into the panko breadcrumbs, ensuring full coverage. Set aside on a wire rack for 10 minutes.
Make the Honey Mustard Sauce: In a small bowl, whisk together the mayonnaise, Dijon mustard, honey, yellow mustard, and apple cider vinegar until smooth. Taste and adjust sweetness or tanginess as needed.
Fry the Chicken: Heat 2 inches of vegetable oil in a heavy-bottomed pot or deep skillet to 350°F (175°C). Carefully place one or two chicken cutlets into the hot oil, ensuring you do not overcrowd the pan. Fry for 4 to 6 minutes per side, until golden brown and the internal temperature reaches 165°F (74°C).
Drain: Remove the chicken and place it on a wire rack set over a baking sheet to drain excess oil. This prevents the bottom from steaming and losing crispness.
Toast Buns: Lightly butter the cut sides of the brioche buns and toast them in a dry skillet over medium heat until golden brown.
Assemble the Burger: Spread a generous layer of honey mustard sauce on both the top and bottom toasted buns. Place a piece of lettuce on the bottom bun, top with the crispy chicken fillet, add pickle slices, and finish with the top bun.
Notes
For an air fryer option, spray the breaded chicken lightly with cooking spray and cook at 380°F (195°C) for 15 to 18 minutes, flipping halfway, until internal temperature is reached. Deep frying yields the best crisp texture.
Resting the breaded chicken for 10 minutes before frying allows the coating to adhere better, preventing it from falling off in the oil.
Use a thermometer to monitor oil temperature; if it is too low, the chicken absorbs too much oil and becomes soggy.
