McDonald's Big Arch: A colossal two-patty debut with a bold new sauce
McDonald’s is rolling out the Big Arch burger in the U.S. for a limited time: a hefty two-Quarter Pounder sandwich built on a large sesame-poppy bun with white cheddar, crispy onions, raw onions, and a new Big Arch sauce. Priced around $10.19 in New York City and about 1,020 calories, the sauce is ketchup-forward with mustard and pickle notes, the cheddar adds sharpness, and the raw onions provide a strong bite. It’s tasty and satisfying but very filling—great for sharing or enjoying on a special occasion while it lasts.
