What Makes the Burger King Royal Chicken Sandwich One of the Best Chicken Sandwiches? 

With the introduction of the Burger King Royal Crispy Chicken Sandwich, BK changed the chicken sandwich game forever. This sandwich is so seductively simple, consisting of only a batter-dipped chicken cutlet, Royal Sauce, shredded lettuce, and a slice of tomato; you might think it’s bland and boring, but after one bite you’ll know that’s not true.

If you have not tried a Burger King Royal Crispy Chicken Sandwich, now is your chance to make one at home. 

Why You’ll Love This Recipe 

Although there’s no denying the BK Royal Sauce is the star of the show, the chicken patty is no slouch. The seasoned breading ensures a crispy bite and moist and juicy chicken! With the potato bun and fixins, you wind up with an excellent chicken burger!

Do you find deep-frying intimidating? That’s okay because this recipe calls for a pan-frying method that is much more accessible to novice cooks.

Recommendation About Oil to Fry In 

Whenever you fry chicken, you must use a neutral oil with a high smoke point to prevent burning. Grapeseed and canola oils are great options. Peanut oil will give you wonderful results, but avoid it unless you know no one with peanut allergies will be eating the chicken sandwich. 

How to Make a Burger King Royal Crispy Chicken Sandwich

To prepare the BK Royal Sauce:

  1. In a small mixing bowl, whisk together the mayo, ketchup, and Dijon mustard. 
  2. Once fully incorporated, add the remaining BK Royal sauce ingredients except for the salt and pepper. 
  3. Taste the sauce and adjust the flavor with salt and freshly ground black pepper to taste. 
  4. Cover the bowl with plastic wrap and refrigerate for at least 30 minutes before using.

To bread the chicken cutlets:

  1. Trim any skin or fat remaining on the chicken cutlets and reserve them for later. 
  2. Set up the breading station with two shallow bowls (pie tins work great) and a wire rack set on a rimmed baking tray. 
  3. In the first bowl, whisk together the buttermilk and eggs. 
  4. In the other bowl, use a fork to combine the flour, smoked paprika, garlic powder, onion powder, salt, and freshly ground black pepper.

  1. With one hand, coat both sides of the chicken cutlet in the buttermilk and egg mixture and drop it in the flour mixture. 
  2. Use your other hand to dredge both sides of the chicken cutlet in the flour mixture and shake off any excess. Place it on the wire rack
  3. Repeat with the remaining chicken cutlets.

To fry the chicken cutlets:

  1. Place a heavy-bottom skillet or frying pan over medium-high heat. 
  2. Add about a half-inch of cooking oil to the skillet and wait until it reaches 350°F. Use a thermometer gun to ensure the proper temperature or test with a pinch of flour. The flour will sizzle immediately when the oil is ready.
  3. Without overcrowding the skillet, add two or three breaded chicken cutlets to the hot oil. Cook until golden brown on both sides. It should take about four to five minutes per side. 
  4. Use a spatula to remove the chicken patties from the oil and place them on the paper towel-lined wire rack
  5. Repeat with the remaining breaded chicken cutlets. You may need to add more cooking oil.

To assemble a sandwich:

  1. Toast the hamburger buns.
  2. While the buns are toasting, slice the tomato and shred the lettuce. 
  3. Spread the Royal Sauce on the toasted bottom bun, and place the cooked chicken patty on the sauce. Top with the shredded lettuce and a slice of tomato.

Possible Recipe Variations 

Customizing your own Burger King Royal Chicken Sandwich at home is a great reason to make it yourself. You can easily adjust the recipe to your liking, and there are countless ways to do so. Share your favorite recipe mods in the comments section below.

  • Spice things up. Add cayenne pepper to the flour mixture and a few dashes of your favorite hot sauce to the buttermilk mixture. 
  • Swap out the BK Royal Sauce for a different one. Mustard BBQ sauce works well here, but you can get even more creative using honey mustard, Campfire Sauce, or cheese sauce!
  • Bacon makes everything better. A few strips of extra crispy bacon will add a distinct smoky flavor to the chicken sandwich. 

What to Serve With a Royal Chicken Sandwich

Stick with the classic sides available at Burger Kings, like french fries and onion rings, or get more creative with these ideas:

How to Store a Burger King Crispy Chicken Sandwich

Allow the chicken patties to cool to room temperature before transferring them to an airtight container. Cooked patties will stay fresh in the fridge for up to three days. Keeping the lettuce and tomatoes whole significantly extends their shelf life. Save the Royal Sauce in a separate container in the fridge for up to a week. 

What Is the Best Way to Reheat a Burger King Crispy Chicken Sandwich

The best way to rewarm a chicken patty is in the air fryer. If you don’t have an air fryer, use an oven set to convection:

  1. Preheat the air fryer to 375°F or the oven to 400°F.
  2. Place the cooked chicken patties directly on the air fryer grates or a baking tray. 
  3. Cook the chicken patties until warmed through, about four minutes in the air fryer or six minutes in the oven. Add the hamburger rolls for the last minute of cooking time to warm them.
