If you have never experienced an In-N-Out Burger, here is your chance to make it at home. If you have, you can now enjoy it without leaving the comfort of your own home.
1/4 c. mayonnaise
2 T. ketchup
1 T. sweet pickle relish
1/4 te. Worcestershire sauce
1 lb. ground chuck
1 t. kosher salt
1/4 t. ground black pepper
4 slices American cheese, optional
4 hamburger buns, lightly toasted
1 large beefsteak tomato, thinly sliced into 8 slices
4 large iceberg lettuce leaves
4 thin white onion slices from a white onion
Stir the mayo, ketchup, relish, and Worcestershire sauce together in a bowl to make the spread. Set aside.
Mix the ground meat, salt and pepper together in a bowl. Form the meat into 4 thin quarter-pound patties, each about 4 inches in diameter and 1/2 inch thick.
Heat a large cast iron skillet or griddle over medium-high heat for at least 5 minutes until very hot. Add as many patties as will fit comfortably, but do not overcrowd. Cook about 2-3 minutes, until the sides of the burger patty are opaque.
Flip each burger patty; top with a slice of cheese, if desired. Cook until the cheese begins to droop and melt at the corners and edges. Repeat with the remaining burgers and cheese.
While the burgers cook, slather the bottom half of each bun with about 1 tablespoon spread. To build each burger, top the spread with 2 tomato slices, 1 lettuce leaf, the cooked burger, 1 slice onion, and finish with the top bun.
Serve immediately.
