Burger King's newest Whopper is turning heads.
On April 1, the fast food chain announced it's selling a meatless Whopper made with a plant-based patty from Silicon Valley startup Impossible Foods. The flame-grilled burger, which is meant to taste just like the restaurant's regular Whoppers, is being tested out at 59 Burger King restaurants in St. Louis. If the results are good, the Impossible Whopper will hit menus nationwide.
Burger King's announcement surprised a lot of people—partly because it was made on April Fools' Day. But it wasn't a joke. People in St. Louis posted photos of their Impossible Whoppers on Twitter, proving the burger not only exists but also looks pretty much like a regular Whopper.
The Impossible Whopper is one of the most notable examples of the growing plant-based trend. Last spring, White Castle announced it was rolling out an Impossible Slider, and in January, Fatburger added an Impossible Burger to its menu. Carl's Jr. recently partnered with another plant-based meat company, Beyond Meat, to put the Beyond Burger on its menu.
Still other companies have expanded their vegan and vegetarian options in an effort to keep up with the growing trend. Taco Bell revealed new vegan items, including a Vegetarian Quesarito, and Chipotle launched the Lifestyle Bowls line to win over customers following paleo, Whole30, and keto diets.
It's important to note that the Impossible Whopper isn't vegan; it still comes with mayo.
The new Whopper costs about $1 more than the meat version. It's available for a limited time at Burger King's St. Louis locations.
