McDonald’s has spent decades perfecting the art of the fast-food heavyweight.
From stacked patties to iconic sauces, the fast food chain knows exactly how to push familiar flavours just far enough to get people talking. Every now and then, though, something slips onto the menu that feels less like a limited-time gimmick and more like a new mainstay.
Over the past year, one particular burger has quietly built a reputation that refuses to die. It didn’t rely on flashy marketing or novelty toppings. Instead, it leaned into excess (more meat, more sauce, more everything) and trusted customers to do the rest. Social media chatter grew louder by the week, with comparisons to McDonald’s most famous burger becoming unavoidable.
Some praised its size. Others focused on its indulgent sauce. A few warned that eating it required both hands, several napkins, and a level of commitment normally reserved for competitive sport. Still, regardless of opinion, it was obvious that the people wanted it back.

Now, McDonald’s has confirmed to Metro that the burger dubbed a ‘Big Mac on steroids’ is officially returning to UK and Ireland menus, and this time, it’s here to stay. The Big Arch, which first launched last summer, will make its permanent comeback on January 5, 2026.
The Big Arch is built to tackle serious hunger. It features two Quarter Pounder beef patties layered with white cheddar cheese, crispy onions, fresh onions, shredded lettuce, crunchy pickles, and the signature Big Arch sauce, all packed into a sesame and poppy seed bun. It’s wider and heavier than a Big Mac, and McDonald’s has described it as the biggest burger it sells.
Some still may prefer the Big Tasty, which made a return via McDonald’s’ latest festive menu, but this is a welcome return for many.
After all, fans haven’t been shy about sharing their verdicts. After it first appeared in the UK, one rave reviewer wrote: “I’ve tried it today, absolutely delish and much, much better than any other burgers on the menu, honestly!”
Another added: “Verdict - delicious. Combining the best bits about the Big Mac but with bigger burgers. Only one negative was that by the end it was falling apart.”
That structural issue has come up more than once, alongside complaints about price. One Redditor questioned: “But is it £8 delicious??” while others admitted it’s not exactly ideal for eating on the move.
Still, praise has continued to outweigh the criticism. One fan on the r/UKfood subreddit, first spotted by East Anglian Daily Times, commented: “I think its the best burger they’ve done in a long time. Love it,” said one fan, while another commented: “It’s great, the best burger I’ve ever had at McDonald’s…..yeah, damning with faint praise maybe, but it’s definitely a good burger.”
McDonald’s appears confident the Big Arch has earned its place. As the brand put it: “The Big Arch isn’t just a burger; it’s built for those serious hunger moments that deserve more.”
