Does Jack in the Box Have a Secret Menu?

Yes, there is a secret menu at Jack in the Box. However, it's not an official secret menu and is made up of custom orders created and shared by fans of the chain.

If you’re wondering, "What is the Jack in the Box secret menu?", it mainly comprises regular menu items with added extras, such as more toppings or ingredient swaps. There are also some Jack in the Box off-menu items that combine official menu dishes, such as sourdough burgers merged with grilled cheese sandwiches.

2. Bacon-Bacon Cheeseburger

Take your bacon cheeseburger to the next level by ordering a Bacon-Bacon Cheeseburger off the Jack in the Box secret menu. The burger is prepared by crumbling bits of bacon into the patty before it's cooked, then adding on the regular bacon slices and any additional toppings you'd like.

If you love bacon (and who doesn’t?), trying this fully-loaded burger is the way to go. It may even become a top pick on your list of the best fast food burgers. 

How To Order

3. Sourdough Bread

If you love the Sourdough Jack, then you’ll love this Jack in the Box secret menu hack: adding sourdough bread to any sandwich. You can order sourdough bread as a replacement for the bun with all regular menu burgers, chicken sandwiches and breakfast sandwiches. We also love ordering some sourdough on its own and topping it with butter for a tasty toast treat.

How To Order

• Any Burger or Sandwich of Your Choice
• Remove: Bun
• Add: Sourdough Bread

4. Maple Bacon Cheesecake

If you’re looking for a sweet treat from the Jack in the Box secret menu, check out the Maple Bacon Cheesecake. Order this decadent fast food dessert by asking for a slice of creamy New York-style cheesecake with a side of bacon bits and syrup from the breakfast menu.

You might have to pay extra for the sides, but trust us, it will all be worth it once you take that first salty-sweet bite. We also love adding bacon bits and syrup to a vanilla milkshake for a sippable version of this delicious dessert. 

How To Order

• Cheesecake
• Bacon Bits
• Syrup

5. Jalapeño Popper Nachos

This Jack in the Box secret menu item might be self-explanatory, but while simple, it's utterly delicious and well worth the order. If you’d like to try the Jalapeño Popper Nachos, just order a side of stuffed jalapeños (we recommend at least one order of seven pieces).

Then, ask for a side of cheese sauce to smother on top. You can even add bacon bits for extra crunch and flavor. We found that this Jack in the Box secret menu hack also works great with nuggets in place of or alongside the jalapeño poppers. 

How To Order

• Stuffed Jalapeños
• Cheese Sauce
• Bacon Bits (optional)

6. Western Taco 

For a tangy twist on a classic taco, order the two regular tacos, a side of onion rings and some barbecue sauce. Once you’ve added all the ingredients together, you’ve got a Western taco straight from the Jack in the Box secret menu.

Order the tiny tacos too for a cuter, tinier version of this hidden menu item. You can also add other sauces alongside or instead of the barbecue sauce. Some of our favorites include cheddar cheese sauce and Secret Sauce. 

How To Order

• Tacos
• Onion Rings
• Barbecue Sauce
• Other Sauces (optional)

7. A Cup of Sauce

Love adding extra sauce to your order? If so, this next Jack in the Box secret menu item is a dream come true! While this may not be available at every location, some outlets can fill a whole drinks cup with your favorite sauce, whether that be ranch, Secret Sauce or any other condiment.

You can then dip to your heart's content. We especially love dipping fries, chicken strips or jumbo egg rolls. Just remember that this secret Jack in the Box menu item will cost more than a single-serve sauce container.

How To Order: Ask if a soda cup can be filled with the sauce of your choice. 

8. Extra Cheese

Make any item ordered from the regular menu even better by adding cheese. While this may not seem like an overly unique Jack in the Box secret menu item, many people don't realize that you can take anything to the next level by just adding more melty, gooey, delicious cheese.

Mix and match Swiss and cheddar or stick with your favorite and easily upgrade any burger, sandwich or side. Extra cheese could also involve adding cheese sauce instead of slices. Or, go all out and get all three kinds from the regular menu!

How To Order

• Menu Item of Your Choice
• Swiss, Cheddar and/or Cheese Sauce

9. Add Onion Rings

Another super simple but incredibly tasty Jack in the Box secret menu item, this hack simply involves combining any regular menu burger or sandwich with onion rings for added flavor and crunch. Add just one or two for a slight update, or go all out and add the whole order of onion rings; we won't judge! 

How To Order

• Burger or Sandwich of Your Choice
• Onion Rings

10. Add Bacon 

Love bacon? If so, this Jack in the Box secret menu hack can't be missed. Bacon is one of those perfect ingredients that instantly makes any meal better, and no matter which regular (or hidden menu) item you choose, adding bacon is sure to make a mouthwatering combination.

Add some bacon bits to your salad or extra bacon to your burger, and taste the difference for yourself!

How To Order

• Menu Item of Your Choice
• Bacon or Bacon Bits

11. Soda Float

Turn your favorite soda into a float with this easy and tasty Jack in the Box secret menu hack. All you have to do is order a soda and ask for some vanilla milkshake to be added on top. Asking for 2/3 of a soda with the rest being milkshake is a good ratio, but you can ask for more or less milkshake if desired.

You might also have to create the float yourself by ordering the two drinks separately and mixing them in an empty cup. This may actually work out well if you and a friend both want to try this Jack in the Box secret menu drink, and you're happy to have closer to a half-and-half amount of soda to milkshake.

Soda options vary but generally include root beer, Fanta, Dr Pepper and Coca-Cola. You could also turn energy drinks, such as the Strawberry Red Daze Red Bull Infusion, into a caffeinated soda float. 

How To Order

• 2/3 Soda of Your Choice
• 1/3 Vanilla Milkshake

12. Add a Grilled Cheese Sandwich 

There is already a sourdough grilled cheese sandwich on the menu for when you want something lighter. But what about when you want something more indulgent without foregoing a grilled cheese? In that case, turn to this Jack in the Box off-menu item.

All you have to do is order the sourdough sandwich of your choice (including using the above Jack in the Box secret menu hack to turn a sandwich with a bun into a sourdough sandwich) and ask for a grilled cheese to be added as an extra layer on top. While this is most definitely not the healthiest item at Jack in the Box, we found that it's one of the most delicious!

How To Order

• Sourdough Sandwich
• Sourdough Grilled Cheese
