TIP: If you want more toppings on the burgers we recommend you keep it simple: ketchup, pickles, or chopped onions.
Ingredients
Sauce
1/2 cup mayonnaise
2 to 3 tablespoons tomato ketchup
1 teaspoon spicy brown mustard
1 tablespoon diced pickle
1 tablespoon diced onion
1 to 2 teaspoons hot sauce
Burgers
3 tablespoons unsalted butter, melted
1 tablespoon Worcestershire sauce
2 teaspoons fish sauce
1 teaspoon garlic powder
1 pound ground beef (85 percent lean)
Kosher salt and freshly ground black pepper
Sliced Cheddar cheese
Toasted split hamburger buns
Directions
To make the sauce: In a small bowl, whisk together the mayonnaise, ketchup, mustard, pickle, onion, and hot sauce. Set aside.
To make the burgers: In a large bowl, whisk together the butter, Worcestershire, fish sauce, and garlic powder. Add the ground beef and mix gently until fully combined. Divide into 6 equal balls, place on a plate and freeze for 15 minutes. You can make the balls earlier in the day and keep them in the refrigerator until you’re ready to cook them.
Heat a cast-iron skillet over medium-high heat until hot. Slightly smash the balls of meat to form disks. Sprinkle the patties with salt and pepper. Place in the hot skillet. Using a flat stiff spatula, smash each patty until it is 1/2 inch thick. Cook without flipping until the bottom is charred. Flip and smash the patties slightly again and top with cheese. Cover the skillet for a few minutes until the cheese melts.
Transfer the burgers to the bottoms of the toasted buns, top with sauce and cover with the tops.
