McDonald's is reportedly launching its massive 'Big Arch' burger in the United States after successful tests in Canada and at the company's Chicago headquarters. The new sandwich features two quarter-pound beef patties, three slices of white processed cheese, crispy onions, slivered onions, pickles, lettuce, and a special tangy 'Big Arch' sauce, all on a sesame and poppy seed bun.

Why it matters

The introduction of the Big Arch represents McDonald's effort to cater to customers looking for a bigger, more indulgent burger option beyond the classic Big Mac. This could help the fast-food giant appeal to those seeking a 'cheat day' splurge, though the sandwich's 1,030-calorie count may raise some health concerns.

The details

According to social media reports, the Big Arch will officially hit U.S. menus on March 3. The unique burger has already been available in Canada and was previously offered at McDonald's headquarters in Chicago. The sandwich is described as a 'love child' of a double Quarter Pounder and a Big Mac, combining two quarter-pound beef patties, three slices of white processed cheese, crispy onions, slivered onions, pickles, lettuce, and a special tangy 'Big Arch' sauce.

  • The Big Arch will launch in the U.S. on March 3, 2026.
  • The burger has previously been available in Canada and at McDonald's headquarters in Chicago.
