McDonald's is launching a new version of its iconic Big Mac, replacing the traditional beef patties with tempura-battered chicken. The Chicken Big Mac, which has been tested internationally and in select U.S. markets, will be available nationwide starting October 10th. It features the same toppings as the original Big Mac, including special sauce, lettuce, cheese, and pickles, all on a sesame seed bun. McDonald's is also partnering with streamer Kai Cenat to promote the new sandwich through live events on social media platforms.
