Cooking steps

1
Make the Smashed Jack sauce: In a small bowl, mix together mayonnaise, dill pickle juice, yellow mustard, garlic powder, and onion powder until smooth. Cover and chill until ready to use for that classic Jack in the Box tang.
-
2
Form the beef into four loose 2-ounce balls, ensuring not to overwork the meat to keep the patties tender and juicy.
-
3
Heat a cast iron skillet or flat-top griddle over high heat until smoking hot (about 450°F). Lightly butter the cut sides of each brioche bun and place them cut-side down on the griddle, toasting until golden and crisp but still soft inside (about 1-2 minutes). Remove and set aside.
-
4
Place beef balls on the hot griddle and immediately smash firmly with a heavy spatula until they are very thin (about 1/4-inch thick). Sprinkle each patty with kosher salt and black pepper. Let cook without moving for 60-90 seconds until edges are deeply crispy and lacy—this is the signature Jack in the Box burger texture.
-
5
Flip the patties, add one slice of processed American cheese on top of each, and cook for another 30-45 seconds until the cheese is perfectly melted and the patty is cooked through.
-
6
On the bottom half of each toasted brioche bun, spread a thin, even layer of Smashed Jack sauce. Layer with a few pickle slices, some shredded lettuce, the hot cheesy smashed patty, and finish with the top bun spread with a bit more sauce.
-
7
Serve the sliders hot, wrapped in parchment or slider baskets for an authentic Jack in the Box presentation, and enjoy those signature crispy edges and tangy sauce in every bite.
