US-based quick-service restaurant chain Jack in the Box has unveiled the Big Smashed Jack burger, an upgrade to its existing Smashed Jack.
The company said in a statement that the new item offers a bigger and better experience, containing almost three times as much beef as a leading competitor’s burger.
The Big Smashed Jack features two quarter-pound smashed patties, American cheese, fresh toppings and a special sauce on a triple brioche bun.
The original Smashed Jack debuted in January 2024.
Jack in the Box is also rolling out several limited-time offers.
The $5 Big Deal Breakfast Meal features a choice of a classic ham, bacon or sausage Breakfast Jack, a crispy hash brown and three French Toast Sticks with syrup.
