All-American Burger Chain Gets Saucy with Impossible Foods with Buy-One-Get-One-Free Impossible Burgers, In-Store Activations, and More

LOS ANGELES, Nov. 04, 2025 (GLOBE NEWSWIRE) -- Fatburger, the iconic burger concept owned by FAT Brands Inc., is teaming up with Impossible Foods to celebrate World Vegan Month across its locations nationwide with an exclusive Buy-One-Get-One FREE Impossible^® Burger promotion running all month long. To redeem, customers can order online through fatburger.com using promo code BOGOIF.

To add more sizzle and sauce to the festivities, the brands are also launching the White Tee Challenge, the ultimate event for messy food lovers and plant-based fanatics alike. Taking place at select locations this month, the flavor-packed activation invites fans to grab a free Impossible Burger, layer on their favorite sauces, and see if they can keep their white t-shirt spotless – or just lean into the mess!

Guests who register online to partake in the challenge will receive a free Impossible Burger and an exclusive White Tee at participating Fatburger locations. Fans can then sauce their burger to their liking, choosing from a variety of limited-time, flavor-packed sauces developed exclusively for the challenge – from Pickleback Buffalo and Chipotle Ranch to Honey Sriracha and Avocado Ranchero. Whether their white t-shirts end up saucy or clean, Fatburger and Impossible Foods invite participating fans to capture their creativity on social media by tagging @Impossible on Instagram. Either way, every participant walks away a winner! Additional details on participating stores and event dates are as follows:
