Ingredients

Burgers

  • 1 tablespoon vegetable oil
  • 2 pounds ground beef chuck preferably 80% lean
  • 4 hamburger buns split
  • 1/4 cup yellow mustard
  • salt and pepper to taste

Animal Style Sauce

  • 1/4 cup mayonnaise
  • 2 tablespoons ketchup
  • 1 tablespoon sweet pickle relish
  • 1/2 teaspoon white vinegar

Toppings

  • 2 large onions finely chopped
  • 1/2 teaspoon salt
  • 1/4 cup sliced dill pickles
  • 4 pieces iceberg lettuce whole or shredded
  • 4 to 8 thin slices tomato
  • 8 slices American cheese

Instructions

  • Cook the Onions: Place a large skillet over medium heat. Add oil, the chopped onions and salt. Sauté for 5 to 8 minutes stirring regularly, adding a tablespoonful of cold water when required to prevent sticking. Once the onions are caramelized brown, remove from heat. Set aside.
  • Make the Animal Style Sauce: In a medium bowl, mix the ketchup, mayonnaise, relish and vinegar. Set aside.
  • Prepare the Toppings: Prepare the pickles, lettuce, tomato slices and set aside.
  • Make the Beef Patties: On a work surface, shape the ground beef into 8 patties about a ½ inch thick using your hands. Season with salt and pepper and set aside.
  • Prepare the Buns: Brush the buns lightly with oil and place on a skillet for 2 to 3 minutes. Spread a tablespoon worth of the prepared animal style sauce onto each bun followed by the prepared toppings to your liking. Set aside.
  • Cook the Burgers: Place a large skillet over medium-high heat. When hot add the beef patties. Slather a teaspoon of mustard onto each patty and cook or 3 to 4 minutes. Flip the patties and cook 3 minutes more, or until the beef reaches an internal temperature of 160°F. Add cheese on top of the burger during the last 1 minute.
  • Assembly: Spread animal style sauce on top of a bun. Then place 1 cooked patties onto a bun. Add with a spoonful of caramelized onions. Then place a second patty on top (this is the double double). Finally, add other toppings followed by the top bun. Repeat for the remaining patties to make 4 double-double burgers in total.

Notes

  • Use high-quality ground chuck beef with 20% fat. This will create the best tender and juicy burger.
  • Shape your patties slightly wider than the bun because they’ll shrink once heated. 
  • Season the beef after it’s shaped into patties, as salt could toughen your burger if you salt the ground beef before forming it into patties.
  • Make a thumbprint indentation in the center of each patty before cooking. This will help patties hold their shape during cooking.
  • Once in the skillet or on the grill, let patties sear well before flipping. Also, make sure not to press down on the burger.
