The Shake Shack The Big Shack burger is being launched to give fans and newcomers alike in the UK with a great reason to head to their nearest location this month to help finish off the summer in a decidedly indulgent manner.
The burger boasts two 100% Aberdeen Angus cheeseburgers stacked together with lettuce, onions, tomatoes, and pickles with a total of three toasted potato buns in the mix. These ingredients combine to achieve an indulgent taste and texture experience, and offers a decidedly Americana cuisine-inspired recipe that speaks to the popularity of US culinary techniques in the UK.
The Shake Shack The Big Shack burger will be on offer from August 17 through 31 and celebrates National Burger Day in the UK (August 27, 2026).
