Regarding elevating the classic burger, Jack In The Box has outdone itself with the Sourdough Jack®. This isn’t just another fast-food burger; it’s a gourmet creation that combines premium ingredients and bold flavors for an unforgettable taste.

 If you’re craving a burger that hits all the right notes, from savory to smoky, the Sourdough Jack® is exactly what you’ve been waiting for.

Key Features:

100% Beef Patty: 

The fast food chain Jack In The Box makes its burgers from 100% pure beef, which is spiced up during grilling so that the meat remains sweet and tender. The burgers are very well done, and relish is in every bite of the patty.

Hickory Smoked Bacon:

The thick-cut hickory-smoked bacon adds a smoky crunch to each bite. Its crispy yet tender taste is rich and savory, perfectly complementing the beef.

Melty Swiss-Style Cheese: 

Swiss-style cheese envelops the patty with a rich and creamy quality, a welcome relief from the Sourdough Jack® sandwich’s other strong elements.  

Fresh Tomato:

Take a slice of fresh, ripe, and juicy tomato to add another bright, sweet taste while brightening up the more substantial flavor of the burger. 

Toasted Sourdough Bread: 

The Sourdough Jack® is served in crispy, perfectly browed sourdough slices. The bread’s subtle yet distinct smell complements the intense taste of its contents. 

Mayo & Ketchup:

Mayonnaise and ketchup combine in this creamy dressing with a slight tang. It’s impressive in that it enhances the flavours of all the elements.

A Burger That Stands Out

The true beauty of Sourdough Jack® is its exquisite mix of tastes. Although the hickory-smoked bacon and the flavourful beef patty are the main ingredients, the creamy Swiss-style cheese is an excellent complement to the entire dish, and the toasting of the Sourdough adds just the needed punch to the burger. 

Every bite is a masterpiece, a concert, but in food. Jack In The Box is meant to transform a burger into a meal with a lounge and jazz band. 

Everything, from the delicious beef to the bread’s right color and texture, has been dedicated to creating the quality meal one longs for.
