The Big Arch burger launched in the US on 3 March 2026 at around $8.99, carrying 1,020 calories and nearly double the beef of a Big Mac. It was never a permanent US item — check your app before making the trip.
The Big Arch burger is two quarter-pound beef patties, three slices of white cheddar, onions two ways, lettuce, pickles and Big Arch sauce, at 1,020 calories. It launched in the US on 3 March 2026 as a limited-time item and is permanent in the UK and Ireland.
This is the biggest burger McDonald's has ever sold: 14 ounces against a Big Mac's 3.5 ounces of beef. It arrived after two years of testing in Canada, the UK, Ireland, Germany, Portugal, France and Switzerland, where it did well enough to earn a permanent slot on several boards. This page covers what the Big Arch burger costs by state, the full nutrition, how it compares to the Big Mac, what reviewers actually said, and the availability question that matters most. The rest of the range is on our McDonald's burgers menu, and the full board is on the McDonald's menu with prices.
The biggest burger McDonald's has ever put on a menu. Two quarter-pound beef patties, three slices of white cheddar, onions prepared two different ways, lettuce, pickles and a new Big Arch sauce, on a bun topped with both sesame and poppy seeds. Fourteen ounces in total.
McDonald's tested it across Canada, the UK, Ireland, Germany, Portugal, France and Switzerland from 2024 onward. It performed well enough to become a permanent item in the UK and Ireland before the US ever saw it. The company said it was answering demand for a heartier, more satisfying burger, which in practice means competing with the bigger builds at Burger King and Wendy's.
This is the question most people arrive with, and the honest answer is that it depends where you are. The Big Arch burger was never a permanent US menu item. It launched on 3 March 2026 as a limited-time offer, and by late April reports were describing it as fading from US boards.
McDonald's never set a national price. A March 2026 survey of restaurants across all fifty states recorded a spread from $7.46 to $12.99, which is one of the widest gaps ever measured on a single McDonald's item.
1,020 calories, which puts it among the heaviest single items McDonald's has ever sold. Only the Big Breakfast with Hotcakes at 1,340 goes higher. The protein figure is the redeeming number: the extra beef more than doubles what a Big Mac gives you.
Contains wheat, milk, egg, soy and sesame. The crispy onions add wheat beyond the bun, so it is not suitable for gluten free diets by any modification. Full detail on McDonald's own product page.
The comparison everyone makes, and the differences run deeper than size. These are two different builds with different design logic, not one burger scaled up.
If you want the Big Mac flavour, order a Big Mac. The Big Arch sauce is tangier and the white cheddar is sharper, so the two do not taste alike despite the family resemblance. If you want volume and protein, the Big Arch burger delivers roughly double the beef for $2.50 more, which is decent value on a weight basis even at 1,020 calories.
Reception was mixed rather than glowing, and it is worth reading the criticism as well as the praise before deciding. Three complaints came up repeatedly: the price, the mess, and the sauce.

In the UK and Ireland, yes — it is a permanent menu item there. In the US it launched on 3 March 2026 as a limited-time offer and was never made permanent, with reports by late April describing it as leaving some boards. Check the app with your restaurant selected.
Around $8.99 at the national midpoint, but the spread is enormous. A March 2026 survey found $7.46 in Columbia, South Carolina and $12.99 in Lewiston, Maine. Oklahoma averaged the cheapest state at $8.05, Alaska the highest at $10.32.
1,020 calories with roughly 52g of protein. Only the Big Breakfast with Hotcakes at 1,340 goes higher among single McDonald's items. The meal with fries and a drink comes to about 1,550.
Two 4oz beef patties, three white cheddar slices, crispy fried onions, raw slivered onions, shredded lettuce, pickles and Big Arch sauce, between two pieces of a toasted sesame and poppy seed bun. There is no middle bun.
The Big Arch, by a wide margin. It uses two 4oz patties against the Big Mac's two 1.6oz ones — two and a half times the beef — plus two extra cheese slices. It is 1,020 calories against 590.
No. Big Arch sauce is a separate, tangier recipe developed for this burger. It was the most divisive element in reviews, with some preferring it and others finding it a poor substitute for the original.
Reviews were mixed. The size, the crispy onions and the white cheddar drew consistent praise. The recurring complaints were that it falls apart under its own weight, that the sauce divides opinion, and that the price felt steep in states where it passed $10.
Canada from 2024, then the UK, Ireland, Germany, Portugal, France and Switzerland. It performed well enough to become permanent in the UK and Ireland before McDonald's brought it to American restaurants. Prices in every market we track are on our international menu page.
No, and there is no modification that makes it so. The crispy onions contain wheat on top of the bun, so removing the bun is not enough. It also contains milk, egg, soy and sesame.
