Jack in the Box · Fast Food
Two grilled beef patties, American cheese, lettuce, tomato, pickles, and Jack in the Box’s special sauce come together on a sesame seed bun. It’s built like the chain’s standard burger, just with a second patty and an extra slice of cheese layered in the middle. Diced onions, ketchup, and mustard round out the usual fast-food burger mix. Compared with the single-patty Jumbo Jack, this one leans more on beef and cheese, while the Ultimate Cheeseburger in the same lineup adds a more cheese-heavy build. The bun is the familiar sesame seed version used across Jack in the Box’s classic burgers.
