How to order secret menu items without confusing staff
Jack in the Box doesn’t have an official secret menu, so staff won’t recognize nicknames. Order each hack by listing the regular items and changes you want, for example “a Jumbo Jack with a regular taco added inside” rather than a made-up name.
The Jack app is the easiest way to do this. You can customize toppings item by item, and the order reaches the kitchen exactly as you built it.
- Be specific about what to add or remove.
- Order off-peak if a hack needs extra work.
- Expect to pay for each added item or topping.
- Be patient: some stores won’t do unusual builds.
Most popular hacks
The taco-in-a-burger, swapping fries for Halfsies in a combo, and adding jalapeños to a Sourdough Jack are the most common. They all use regular menu items, so most stores can make them.
