The chicken chain launches a festive menu featuring a new Baileys Hard Shake, gravy pots and a giveaway of 100 free sandwiches.
UK restaurant chain Slim Chickens has unveiled its Christmas 2026 menu, bringing back its popular Big Sleigh festive sandwich alongside a new Baileys Hard Shake and seasonal gravy pots across participating restaurants in the UK.
Launching on 3 November 2026, the festive menu will run until 5 January 2027. The brand is also giving away 100 free Big Sleigh sandwiches through its social media channels to mark the launch.
The returning Big Sleigh features crispy chicken, creamy brie, crispy onions and sweet onion relish, served in a brioche bun. The sandwich is priced at £9.95, while the meal option, which includes fries, house sauce and a bottomless drink, costs £14.25. Customers can also add a gravy pot for an additional £1.50.
A new addition to this year’s festive range is the Baileys Hard Shake, a handspun milkshake featuring the taste of Baileys Irish Cream. It is priced at £7.45 or £4 as a meal upgrade. The alcoholic drink is available exclusively to customers aged 18 and above.
As part of its Christmas launch, Slim Chickens will give away 100 Big Sleigh sandwiches through its UK Instagram and TikTok channels. The promotion begins on 3 November, with customers invited to follow the brand’s social media accounts for entry details.
Millie Collier, Brand Manager at Slim Chickens, said: “Christmas is one of our favourite times of the year at Slim Chickens, and we’re so excited to bring back The Big Sleigh for another festive season. We know how much our guests love it, and this year we’ve made the whole experience even more indulgent.
“With crispy chicken, creamy brie, crispy onions and sweet onion relish in a sweet brioche bun, The Big Sleigh is packed with everything you could want from a festive chicken sandwich. We’re also really excited to introduce our new Baileys Hard Shake, which brings a little grown-up indulgence to the menu and makes the perfect festive treat.
“And of course, we couldn’t kick off Christmas without giving something back, so we’re giving away 100 free Big Sleighs to help spread a little festive cheer. We can’t wait for everyone to get involved!”
Slim Chickens entered the UK in 2018 and operates through a master franchise partnership with Boparan Restaurant Group (BRG), the hospitality business founded by Ranjit Singh Boparan. BRG is responsible for developing the brand across the UK and has also worked with sub-franchise partners to expand its restaurant network.
The brand has surpassed 80 restaurants in the UK, establishing a presence across high streets, shopping centres and retail destinations.
BRG has outlined plans to open between 15 and 20 additional Slim Chickens restaurants over the following 12 months, with drive-thru formats expected to play a significant role in the rollout. The expansion is expected to create between 800 and 1,000 jobs.
Globally, Slim Chickens has built an international franchise network spanning markets across Europe, Asia and the Middle East. Its international expansion model relies on experienced local operators and franchise partners, supported by the brand’s development, training, operational and marketing teams.
Known for its hand-breaded chicken tenders, generous portions and 15 signature dipping sauces, Slim Chickens continues to use menu innovation and new restaurant formats to strengthen its position in the competitive chicken restaurant market.
The Christmas menu will be available at participating Slim Chickens restaurants across the UK until 5 January 2027.
