Overview
- The Big Arch will be available at participating U.S. restaurants starting March 3 for a limited time, with some locations already selling it early, including West Coast franchises and Chicago’s Global McDonald’s.
- The sandwich stacks two quarter‑pound beef patties with three slices of white cheddar, lettuce, pickles, both slivered and crispy onions, and Big Arch Sauce on a toasted sesame‑and‑poppy‑seed bun.
- Outlets report the burger at roughly 1,020–1,057 calories, making it McDonald’s most calorie‑dense U.S. burger, compared with 580 calories for a Big Mac.
- McDonald’s has not set a national price; individual restaurants will determine cost, with one Southern California purchase at $9.39 and estimates of about $10–$11 based on international pricing.
- Piloted across Canada and Europe and now permanent in the U.K., the Big Arch drew praise for meeting demand for a heartier option, and executives and analysts say strong U.S. sales could justify broader or permanent placement.
