McDonald's announces Big Arch burger as a U.S. limited-time item from March 3

McDonald's said the Big Arch, a double-patty burger already on the UK and Ireland menus, will launch in the U.S. for a limited time on March 3, 2026. It has two quarter-pound beef patties, three slices of white cheddar and crispy onions. The company has not ruled out adding it to the U.S. core menu, which would matter more for beef costs and traffic than a limited run.

• Limited-time U.S. launch on March 3, 2026
• Two quarter-pound patties, three slices of melted white cheddar
