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.

Jack’s Lucky Mint Trio features the Oreo Mint Shake, the new Oreo Mint Mocha Sweet Cream Iced Coffee and the Mint Twisted Soda.

Sauced & Loaded Waffle Fries are topped with cheddar cheese and nacho cheese sauce then drizzled with crumbled bacon and buttermilk ranch. 

The 74th Anniversary Deal will feature a classic Jumbo Jack for just 74 cents. 

March Madness Savings will offer Jack Pack members a 50% discount on the Jumbo Jack, the Ultimate Cheeseburger and the Jr Jumbo Jack Cheeseburger from 24 February to 30 March 2025.

The Jr Jumbo Jack Cheeseburger will be priced at $1.29 from 24 March to 6 April. 

The new items and deals will be available from 17 February to 7 April across multiple platforms including in-store purchases, online orders, and through the Jack App. 

In January 2024, Jack in the Box introduced two new flavours to its Jack Wrap line-up in the US: the Fajita Jack Wrap and Caesar Jack Wrap. 

The Fajita Jack Wrap features grilled or crispy chicken strips, caramelised onions, shredded cheddar cheese, lettuce, tomato and chipotle ranch in a warm tortilla. 

The Caesar Jack Wrap offers grilled or crispy chicken strips, shredded lettuce, tomato and Caesar dressing, also in a warm tortilla.
