Why you’ll love this homemade version

Making this at home gives you control over texture, seasoning, and temperature. The chicken cutlets stay juicy because they are brined in a buttermilk-egg mixture, and the exterior crisps up thanks to a seasoned flour dredge and hot oil. The sauce—modeled on the classic BK Royal dressing—adds a bright, slightly sweet tang that complements the savory chicken. Toasted buns and crisp vegetables finish each sandwich so every bite balances crunch, cream, and freshness.

Preparation overview

Start by making the sauce so the flavors have a moment to marry while you prepare the chicken. Then set up a simple dredging station: seasoned flour, buttermilk-and-egg wash, and flour again for a double coating that ensures a crunchy crust. Fry the cutlets in hot oil until golden brown and cooked through. Assemble on toasted buns with sauce, lettuce, and tomato.

Step-by-step instructions

Note: The directions below follow the ingredient list exactly and keep the original order of steps while clarifying each action for reliable home execution.

Make the homemade BK Royal Sauce. In a medium bowl, combine 3/4 cup mayonnaise, 1 tablespoon ketchup, 1 teaspoon Dijon mustard, and 1 teaspoon dill relish or finely chopped pickles. Add 1/2 teaspoon Worcestershire sauce, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, and 1/2 teaspoon paprika. Stir until smooth, then taste and season with salt and pepper as needed. Cover and refrigerate while you prepare the chicken so the flavors meld.
Prep the chicken cutlets. If your boneless skinless chicken breast cutlets are uneven in thickness, lay each between two pieces of plastic wrap and gently pound with a meat mallet or rolling pin until they are an even 1/2-inch to 3/4-inch thickness. Trim any excess so they fit the buns comfortably. Pat the cutlets dry with paper towels—this helps the coating adhere.
Make the seasoned flour. In a large shallow bowl or pie plate, whisk together 1 cup all-purpose flour, 1 tablespoon paprika, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1 teaspoon salt, and 1/2 teaspoon black pepper. Mix until the seasonings are evenly distributed.
Prepare the buttermilk-egg wash. In a separate shallow bowl, whisk 1 cup buttermilk and 2 eggs until smooth. This mixture both seasons and tenderizes the chicken while offering an adhesive layer for the flour.
Dredge the cutlets. Working with one cutlet at a time, first dredge it in the seasoned flour, coating both sides and shaking off any excess. Next, dip the floured cutlet into the buttermilk-egg wash, making sure it is fully coated. Finally, return the cutlet to the seasoned flour for a second coating, pressing gently so the flour sticks and yields a hearty crust. Place dredged cutlets on a clean plate while you repeat for the remaining pieces.
Heat the oil for frying. Pour about 1/2 to 3/4 inch of vegetable oil into a large skillet or heavy-bottomed pan—enough oil to cover the bottom and come up slightly around the cutlets. Heat the oil over medium-high heat until it registers 350°F (175°C) on an instant-read thermometer or until a small pinch of flour sizzles and browns gently when added to the pan.
Fry the chicken. Carefully add two cutlets to the hot oil, leaving space between them to avoid crowding. Fry for 3 to 4 minutes per side, or until the crust is golden brown and an instant-read thermometer inserted into the thickest part of the cutlet reads 165°F (74°C). If the crust is browning too quickly, lower the heat slightly. Remove the cooked cutlets to a wire rack set over a baking sheet to drain and hold; this keeps the underside from becoming soggy. Repeat with the remaining cutlets, adding more oil as necessary and maintaining the oil temperature.
Toast the buns and prep toppings. While the final cutlets fry, split and toast 4 hamburger buns until light golden. Lay out 8 lettuce leaves and slice tomatoes into 4 even slices if not already done.
Assemble the sandwiches. Spread about 1 tablespoon of the homemade BK Royal Sauce (or mayonnaise or your preferred sauce) on the bottom half of each toasted bun. Place a hot crispy chicken cutlet on top of the sauce, then add a tomato slice and two lettuce leaves. Finish with another tablespoon of sauce on the top bun if you like extra creaminess, then close the sandwich.
Serve and enjoy. Serve the sandwiches immediately so the contrast between the hot crispy cutlet and the cool, creamy sauce is at its best. These pair nicely with fries, a simple green salad, or your favorite side.

Troubleshooting and tips

Even thickness: Pounding cutlets to uniform thickness ensures they cook evenly without drying out.
Oil temperature: Keep the oil between 325°F and 350°F. Too cool and the breading absorbs oil; too hot and it browns before the center cooks.
Double-dredge method: The flour–buttermilk–flour system creates a substantial crust that stays crispy. Press the second flour layer gently to adhere well.
Rest on a rack: Use a wire rack instead of paper towels to keep the crust crisp by allowing air circulation underneath.
Make-ahead sauce: The sauce improves after 30 minutes in the refrigerator and keeps for several days in an airtight container.

Variations

Spicy version: Add 1/2 teaspoon cayenne pepper to the seasoned flour and increase the paprika in the sauce for a spicy kick.
Baked alternative: For a lighter approach, spray the double-coated cutlets with oil and bake at 425°F (220°C) on a wire rack for 18–22 minutes, flipping once, until golden and cooked through.
Extra-crunch crumb: After the second flour dredge, press the cutlets into panko breadcrumbs for additional crunch.

Storage

Leftover chicken cutlets can be refrigerated for up to 3 days in an airtight container. Reheat in a 375°F oven on a wire rack for 8–12 minutes until warmed through to help retain crispness. Sauce will keep for about 4–5 days refrigerated; give it a stir before using.

Method

Prepare the sauce: in a mixing bowl combine 3/4 cup mayonnaise, 1 tablespoon ketchup, 1 teaspoon Dijon mustard, 1 teaspoon dill relish (or finely chopped pickles), 1/2 teaspoon Worcestershire sauce, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, and 1/2 teaspoon paprika; season with salt and pepper to taste, mix until smooth, cover and refrigerate at least 30 minutes.

Make the wet dip: in a second shallow dish whisk 1 cup buttermilk with 2 eggs until blended.
Coat the chicken: dip each trimmed chicken cutlet into the buttermilk-egg mixture, then dredge thoroughly in the seasoned flour, pressing gently so the flour adheres; shake off excess.
Heat oil: pour enough vegetable oil into a large skillet to reach about 1/2 inch depth and heat over medium-high until it reaches about 350°F (use an instant-read thermometer).
Fry the cutlets: carefully add the breaded cutlets to the hot oil (do not overcrowd) and fry 4 to 5 minutes per side until golden brown and the internal temperature reaches 165°F; adjust heat as needed to maintain 325–350°F.
Drain the chicken: transfer fried cutlets to a wire rack set over a sheet pan or to paper towels to drain briefly.
Toast buns: toast the 4 hamburger buns until lightly golden.
Assemble sandwiches: spread about 1 tablespoon BK Royal Sauce or mayonnaise on the bottom of each bun, place a fried chicken cutlet on top, add a tomato slice and two lettuce leaves, then cap with the top bun and serve immediately.
