McDonald’s Big Arch burger is arriving in Southern California restaurants

McDonald’s calls it its biggest and “most McDonald’s” burger ever.

Social media users call it a “Big Mac on steroids.”

Its official name is the Big Arch.

The burger made its debut internationally in 2024 and became a big hit in the United Kingdom. Now it’s come home.

It officially goes on sale Tuesday, March 3, but some West Coast franchises are selling it early.

I was able to get it on Wednesday. I ordered it on the McDonald’s app, which listed it as unavailable but sold it to me anyway for $9.39 plus tax.

The Big Arch is indeed a beefy, cheesy, saucy burger. Its ingredients are a little different from a Big Mac or a Quarter Pounder, but it’s recognizable as a McDonald’s product.

It has two quarter-pound beef patties, three slices of white cheddar, both sliced and crispy onions, lettuce, pickles and a new Big Arch Sauce, made with mustard.

It’s all on a toasted bun topped with sesame and poppy seeds.

Early buzz is good. “Think of it as the best of a Big Mac AND a Quarter Pounder combined,” Florida NBC station WPTV posted on Facebook.

McDonald’s has several other specials going on.

Through March 22, customers at Southern California restaurants can add an egg to any breakfast sandwich for $1.50, according to a news release.

Filet-O-Fish sandwiches are available for $2.99 on Fridays through April 17 as well as $2.50 daily for rewards members.
