Meet the Big Arch: McDonald’s New Mega Burger Hit

A new headline-grabbing item has landed at McDonald’s — the Big Arch Burger. It’s trending across the globe, and for good reason. Let’s break down everything you need to know about this exciting launch that’s making fans say, “Bye, Big Mac.”
What Is the Big Arch?
The Big Arch is a bold new entry in McDonald’s global burger lineup:
- Two quarter-pound beef patties
- Three slices of white cheddar cheese
- A unique sesame-and-poppy seed bun
- Fresh lettuce, pickles, crispy and grilled onions
- A new, creamy Big Arch sauce — described by some as a richer cousin of the Big Mac sauce
Weighing almost 14 ounces (400g) and topping 1,000 calories, it’s made to satisfy the hungriest of fans.
Where Can You Get It?
McDonald’s is rolling out the Big Arch globally. Here’s where it’s already making waves:
- UK & Ireland: Launched on June 18, 2025
- Canada, Portugal, Germany: Tested and loved by customers
- U.S. Launch: Planned for late 2025, pending franchise approval
In the UK, it’s priced at £7.99 solo and £9.99 as a meal. In Portugal, it’s around €10.50, and in Canada, a combo costs about CAD $10.
Why the Big Deal?
This isn’t just another burger. The Big Arch marks the first permanent global menu addition since Chicken McNuggets in 1983 — a huge deal for the brand.
According to Business Insider, McDonald’s launched this under its “Accelerating the Arches” strategy — focusing on core classics, done bigger and better.
Social Buzz & Reviews
From TikTok to Reddit, foodies are raving. One Canadian reviewer said it’s “the best burger McDonald’s has ever made.” Over on Mystic Foodies TikTok, the verdict was a “10/10” — especially praising the new sauce and crispy onions.
Even traditional media are excited. HuffPost Spain called it “a Big Mac without the bread in the middle — but twice the meat.”
How Does It Compare?
Compared to the Big Mac:
- Bigger in size and calories
- Bolder flavors with sharper cheddar
