Jack in the Box’s Sourdough Jack has existed for almost 30 years. The combination of a beef patty, hickory smoked bacon, tomato, melted Swiss-style cheese, mayo, and ketchup on toasted sourdough bread is a satisfying savory bomb of a sandwich. But I believe I’ve tasted something better that uses the chain’s sourdough \u2014 the Sourdough Smashed Jack.<\/p>\n
The menu item features a smashed beef patty, American cheese, pickles, grilled onions, and Jack’s Boss Sauce on toasted sourdough bread. It’s basically a Classic Smashed Jack, but with the brioche bun swapped for sourdough bread. There’s also a version that comes with a second patty and bacon.<\/p>\n

My taste buds were tantalized by the Sourdough Smashed Jack because they enjoyed the tasty Boss Sauce, which isn’t a new condiment and debuted with the original Smashed Jack. Although the classic version came out in January, I missed tasting it because it quickly sold out. But when it came back on the menu, I was distracted by newer, younger products, so I just got around to trying a Smashed Jack now. <\/p>\n

Anyhoo, back to the sauce. It’s the primary reason why the Sourdough Smashed Jack tastes excellent. Its sweet and tangy flavor is “secret sauce”-like, and it’s enhanced by the onions and pickles. The orange cheese slice helped prevent the pickles and onions from falling out and gave the burger a welcome savory kick. As for the beef patty, I think it was smashed, or maybe it’s just thin, but it didn’t have the crispy edges that smashed burgers are known for. Although its meatiness comes through, I kind of wish this had a second patty. The sourdough bread was buttery, but like I’ve experienced with other menu items that feature it, it doesn’t have a notable flavor.<\/p>\n
Jack in the Box Sourdough Smashed Jack is one savory, tangy, and tasty boss of a sandwich, thanks to that Boss Sauce. But I imagine it’s not that different tasting than the equally priced Classic Smashed Jack.<\/p>\n
