Burger King is taking its plant-based Impossible Whopper nationwide.

The fast-food chain announced the meatless and vegan burger will be available at more than 7,000 locations for a limited time starting Aug. 8. It also will be available for delivery through the BK App and through DoorDash.

The announcement comes four months after a pilot started in St. Louis area locations, which later expanded to other markets. Burger King announced in late April it planned to bring the meat-free option to all restaurants by the end of 2019.

“We’ve heard great feedback and know the Impossible Whopper appeals to both current guests who are already big fans of the Whopper sandwich, as well as new guests who are excited about this new option,” Chris Finazzo, Burger King's president for North America, said in an Aug. 1 statement.

Burger King said in its announcement that it is the first coast-to-coast quick-service restaurant to serve the plant-based patty from food startup Impossible Foods, maker of the Impossible patty.

The Impossible Whopper will have a suggested retail price of $5.59, but pricing and availability can vary.

From Aug. 8 through Sept. 1, Burger King has a deal it's calling the “Impossible Taste Test.”

Exclusively on DoorDash and the BK App, get an Impossible Whopper and the original Whopper for $7. DoorDash also is offering free delivery on the $7 Taste Test or one Impossible Whopper through Sept. 1 with promo code IMPOSSIBLE.

Permanent place on menu?

José Cil, CEO of Burger King’s parent company Restaurant Brands International, said during the company’s Aug. 2 earnings call with analysts that “all of our product launches, particularly here in the US, are inherently limited time offers.”

“Being brand led and being guest centric, we let our guests decide which items should earn a permanent place on our menus,” Cil said. “We're very excited about the prospects of building a platform with plant-based burgers and other menu options, but we're starting as we always do and let's see what happens.”

And while the burgers are meatless and plant-based, there is some fine print on the Burger King website.

The website notes with an asterisk that the Impossible Whopper is "*Flame-grilled in the same broiler used for beef and chicken."

New grocery store option coming

You soon will be able to grill your own Impossible burger.

On July 31, the Food and Drug Administration approved a key ingredient included in Impossible Foods patties. With the approval, Impossible Foods can sell in grocery stores, which its competitor Beyond Meat, already does.

Impossible Foods said it plans to "launch its flagship product in grocery stores in September."
