McDonald’s is putting a twist on the Big Mac sandwich that has been a fan favorite since 1968. Its newcomer is the Chicken Big Mac.

The sandwich has previously been tested in international markets including the U.K., and also tested in Miami in 2022. The sandwich is set to make its debut in the U.S. for a limited time starting Oct. 10.

The Chicken Big Mac swaps out the two all-beef patties on the traditional Big Mac for a pair of tempura battered chicken patties. Otherwise, the toppings are the same: the Big Mac bun, Big Mac sauce, cheese, lettuce and pickles.

“With the introduction of the Chicken Big Mac, we’re excited to pay homage to one of our most iconic menu items, the Big Mac, and introduce it to a whole new generation of fans,” said Tariq Hassan, Chief Marketing and Customer Experience Officer at McDonald’s USA, in a press release. “By tapping into some of our fans’ biggest passions from dupe culture to live-streaming, we’re able to serve up more than just a sandwich. There truly is something for everyone to enjoy in this campaign and we’re bringing experiences that will surprise and delight them, all before the Chicken Big Mac hits restaurants.”

One thing that needs to be settled: is the Chicken Big Mac a Big Mac? To help get to the bottom of it, McDonald’s is getting help from online streamer, Kai Cenat, who will welcome his famous friends to try the sandwich on his livestream and share their unfiltered reactions.

You can follow along on McDonald’s social channels all month long to find out when Kai and his friends will be going live and giving their opinions on if a Chicken Big Mac is a Big Mac.
