Equipment

1 Large bowl
1 Skillet or Griddle
1 Small Bowl

Ingredients

1 pound ground beef 80/20 fat
1 teaspoon kosher salt
10 cracks fresh black pepper
6 six-inch flour tortillas (flour works best — they’re more absorbent and the meat sticks better)
6 slices muenster or provolone cheese
Shredded lettuce
Chopped white onion
Dill pickle chips

In-N-Out Style Sauce

½ cup mayonnaise
2 Tablespoons ketchup
1 teaspoon yellow mustard
1 Tablespoon pickle relish
1 teaspoon white vinegar
1 Tablespoon finely grated onion

Instructions

Season the Beef:

In a bowl, gently mix the ground beef with kosher salt and cracked pepper. Divide into 6 equal portions and loosely roll into balls.

Smash the Tacos:

Heat a skillet or griddle over medium-high heat. Place a tortilla onto the hot surface.
6 six-inch flour tortillas (flour works best — they’re more absorbent and the meat sticks better)
Immediately top with one beef ball and smash it down flat into the tortilla using a firm spatula or press.

Cook:

Let the beef cook for 2–3 minutes until deeply browned and crispy.
Flip the taco so the tortilla side cooks and gets lightly golden (30–60 seconds).
Top the cooked beef with a slice of muenster or provolone cheese and allow it to melt.

½ cup mayonnaise, 2 Tablespoons ketchup, 1 teaspoon yellow mustard, 1 Tablespoon pickle relish, 1 teaspoon white vinegar, 1 Tablespoon finely grated onion
Mix well until smooth and creamy.
Chill for at least 15–30 minutes to let flavors meld.

Assemble:
