Burger King announced Tuesday that it will begin testing its latest product, Impossible plant-based chicken nuggets, in select locations starting on Oct. 11.

Customers located in test markets Des Moines, Iowa; Boston, Mass.; and Miami, Fla., will have the first opportunity to try the new meatless nuggets made from plants. They will be available in an eight-piece order and for a limited time only.

“This isn’t the first time we’ve teamed up with Impossible to make waves in the industry. In 2019, we became the first quick-service restaurant to serve the award-winning, plant-based Impossible patty and offer the iconic Impossible Whopper,” said Ellie Doty, Chief Marketing Officer, Burger King North America in the press release.

“So, it’s only fitting we’re the first global QSR to test the Impossible Nuggets. We’re excited to hear what our guests in the test markets think of this latest innovation.”

Burger King will be the first-ever restaurant to carry a plant-based chicken nugget. Its newest meatless addition is an opportunity to attract more customers along with a new customer base.

Beef meat substitutes have been the most commonly known and used product for fast-food chains to try out at their locations but adding a chicken substitute is considered rare. Impossible foods had just added “impossible chicken nuggets” to its product selection in early September. Beyond Meats released its version of vegan nuggets in July.

Burger King will be ahead of chief competitor McDonalds, which has a partnership with Beyond Meats but has not yet offered a meatless chicken nugget option.
