Three, fresh, 4 oz, 81/19 beef patties smashed onto a hot griddle to create a caramelized, crispy-edged crust. Stacked high with crispy bacon, a farm-fresh egg and melted American cheese, then layered with crisp lettuce, ripe tomato, onions, pickles, and our signature peppercorn Shack Sauce, this towering burger is juicy, perfectly seasoned, and irresistibly satisfying.
