Jack in the Box Inc. partnered with Impossible Foods to test its plant-based beef patty from October 18, 2021 through December 12, 2021 at participating Phoenix locations. Each restaurant will give guests the option to substitute an Impossible Burger patty for a $1 or $1.50 extra per patty for any Jack in the Box burger on the core menu, including the Bacon Ultimate Cheeseburger, Classic Buttery Jack, Jumbo Jack Cheeseburger and more. The market test makes Jack in the Box the only major QSR allowing guests to sub an Impossible Burger patty for any core burger. With more than 80% of QSR guests seeking plant-based burgers for reasons beyond a strict plant-based diet, Jack in the Box's test with Impossible Foods will aim to meet the expectations of flexitarians and those looking to eat less meat, while maintaining the craveability and menu versatility for which Jack in the Box is known. The Impossible Burger patty cooks, tastes, and sizzles just like a Jack burger with as much protein as 80/20 ground beef, but with 0mg cholesterol (14g total fat, 8g saturated fat per serving) and without antibiotics or animal hormones. The product is made with soy protein, coconut oil, sunflower oil, potato protein and heme. Guests can order Impossible Burger in-store from any of Jack in the Box'sPhoenix locations or through delivery partners including Doordash, Uber Eats, Grubhub and Postmates.
