Buttery Jack

What is it?

Garlic herb butter melts onto the beef patty as it cooks, giving this Jack in the Box burger a richer, more glossed-over look than a standard fast-food cheeseburger. Brioche bun adds a soft, slightly sweet base underneath, and the butter is the main thing separating it from the rest of the menu. Jack in the Box offered a few versions in the lineup, including a bacon and a classic build, but they all share the same core idea: beef, bun, and flavored butter. It's a step above the chain's standard burgers in richness, with that compound butter doing most of the heavy lifting on flavor.
