Burger lovers have a new reason to visit Shake Shack UK this August, with the arrival of The Big Shack, the brand’s biggest and boldest burger to date.
Launching just in time for National Burger Day on 27 August, The Big Shack will be available across the UK from 17–31 August 2026, while stocks last.
What’s in The Big Shack?
Designed for those looking for a seriously satisfying burger, The Big Shack brings together two 100% Aberdeen Angus cheeseburgers, stacked with lettuce, pickles, onions and tomatoes.
The burger is finished with Shake Shack’s signature secret sauce and served inside a three-layer toasted potato bun, creating an extra-generous take on the brand’s classic burger.
As with Shake Shack’s regular menu, The Big Shack is cooked to order, with the brand focusing on premium ingredients and made-to-order preparation.
Scratch Cards Could Win You Free Food
There’s another reason to get your hands on The Big Shack.
Every purchase comes with a scratch card, giving customers the chance to win a selection of Shake Shack prizes. Rewards range from free menu items to a meal for four, adding an extra incentive to try the limited-time burger.
The Big Shack will be available at all Shake Shack UK locations, as well as through delivery, from 17 August until 31 August, or until stocks run out.
