Double Decker Chicken Burger (aka: CopyCat McDonalds Chicken Big Mac)


You don’t have to wait for the Double Decker Chicken Burger, a copycat version of the McDonald’s UK sandwich, to come to the US. You can make this much-loved British trend at home!



For The Special Sauce:

  • ½ cup mayonnaise
  • 2 tablespoons French salad dressing
  • 1 teaspoon ketchup
  • 1 tablespoon sweet pickle relish
  • 1 tablespoon dill pickle juice
  • 1 tablespoon dried minced onion
  • 1 teaspoon granulated sugar
  • Pinch of Kosher salt

For The Tempura Batter:

  • 4 chicken cutlets, pounded so they are of uniform thickness, not more than ⅓-inch.
  • 1 large egg, beaten
  • 1 tablespoon lemon juice
  • ½ cup very cold club soda
  • ½ cup all-purpose flour
  • ½ cup cornstarch
  • ½ teaspoon Old Bay Seasoning
  • ½ teaspoon baking soda
  • Vegetable oil

For The Sandwich:

  • 4 sesame hamburger buns
  • Butter
  • Shredded lettuce
  • 4 slices processed American cheese – I used Velveeta slices.
  • Slices dill pickle


Make the sauce.

In a medium bowl, whisk together all of the sauce ingredients until well combined. Cover the bowl tightly with plastic wrap and chill in the refrigerator until needed.

Make the batter.

In a large bowl, stir together the egg, lemon juice, and club soda.

Whisk in the flour, cornstarch, Old Bay, and baking soda until a batter forms, but do not overmix. Place the bowl in the refrigerator.

In a large, deep skillet, pour enough oil into the bottom so that it comes 1-inch up the side.

Over medium heat, bring the oil up to 350 degrees.

Remove the batter from the refrigerator and dip each chicken cutlet into the batter, making sure that both sides are coated.

Add the chicken to the skillet. Do not overcrowd the pan or the chicken will be greasy. You may need to work in batches.

Cook the chicken until golden brown and crispy and no longer pink in the center. Turn the chicken after 7-8 minutes and cook the other side for another 5 minutes. The time may take more or less time depending on the thickness of your chicken cutlet. 

Remove the chicken to a paper towel-lined baking sheet to drain. 

Top each cutlet with a slice of American cheese.

In another skillet over medium heat, butter the insides of the buns and the middle bun and toast them in the skillet until golden brown. Set aside.

Assemble the sandwich.

Spread the sauce generously on the buttered side of each bun part.

Top the bottom bun with shredded lettuce and pickles.

Place a chicken cutlet on top of the pickles, followed by the second bun bottom with sauce slathered on.

Add a bit more shredded lettuce and pickles.

Place another chicken cutlet on the second bun.

Place bun top on the chicken and gently compress the sandwich so that it holds together.

Serve the sandwich hot with fries or chips on the side.
