Burger King's Whopper Heads to 2026 With Bun, Mayo, and Packaging Upgrades
Burger King is updating its Whopper in 2026 with a sturdier sesame bun, a clamshell-style package, and a citrusy mayo, while keeping the patty unchanged; driven by guest and franchisee feedback, the rollout to more than 7,000 restaurants starts this week and will add about $4,000 in annual costs to each franchisee, which BK hopes won't be passed to customers.
