The plant-based burger battle is heating up once again. Looking to build on the success of its Beyond Famous Star, Carl's Jr. is expanding its partnership with Beyond Meat to launch the Beyond BBQ Cheeseburger.

Drawing on the success of its Beyond Famous Star, the fast food chain developed a new burger build meant to complement the Beyond Burger patty, while drawing on the flavors of its famed Western Bacon Cheeseburger. The result features a Beyond Burger patty topped with Carl's Jr. original BBQ sauce, American cheese, and crispy onion rings, on a sesame seed bun.

“With one Western Bacon Cheeseburger sold every second, we saw this as the perfect flavor inspiration – and so the new Carl’s Jr. Beyond BBQ Cheeseburger was born,” shared Patty Trevino, SVP of Carl’s Jr. Brand Marketing.

Carl's Jr. was among the first major fast food chains to introduce a plant-based option to its menu last December. To date, more than 4.5 million Beyond Famous Star burgers have been sold, making it the most successful burger launch for the brand in the past two years.
