On April 1, Burger King announced that it was testing Impossible (aka plant-based) Whoppers in the St. Louis area-with all the customary fixings you'd expect, like mayo, lettuce, tomatoes, and pickles, simply swapping a meatless patty in for the usual beef. The Impossible Whopper made its soft debut at 59 different Burger King restaurants, with the intention that if the tests went well, a national launch would be on the horizon. Today, Burger King confirmed those plans, announcing its goal to roll out the Impossible Whopper nationwide by the end of 2019.

"The Impossible Whopper test in St Louis went exceedingly well and as a result there are plans to extend testing into additional markets in the very near future," Burger King said in a statement. "Burger King Restaurants in St Louis are showing encouraging results and Impossible Whopper sales are complementing traditional Whopper purchases."

Right now, the Impossible Whopper is still available in St. Louis area, in case you feel like hopping on a plane to try it; details about expansions and future testing sites haven't been announced yet. In the meantime, however, we recently conducted a taste test on all the major players in the plant-based burger industry right now-including the Impossible 2.0 patty, with the addition of the Beyond Burger, Lightlife Plant-Based Burger, and Morningstar Farms Meat Lovers Vegan Burger, to see what meatless options consumers have ahead of grilling season. We found some burgers (almost) identical to beef; others had a more falafel-like flavor. You can find out which one was our ultimate favorite in the full article.
