Here's How To Make Jack In The Box's Secret Sauce

Fast food and fast-casual restaurants always seem to get people talking with one menu item: a secret sauce. McDonald's, for example, has set its Big Mac apart from other fast-food burgers with its mouthwatering Big Mac sauce — something customers have tried to imitate for years. And Shake Shack's chicken sandwich features a dill dressing that you won't find among any of its competitors. Plus, Chick-fil-A fans can't resist dipping their tenders in the classic Chick-fil-A sauce.

At Jack in the Box, customers loved the secret sauce the fast-food chain had offered for years with some of its menu items. When one Reddit user thought they'd found the mystery formula, others responded by calling the sauce "amazing" and said they would be "making a gallon" of it upon learning the recipe. So, what exactly is in the secret sauce that has so many obsessed? It turns out it's not as complicated as the eatery might want you to think.

Here's what's really in Jack in the Box's Secret Sauce

The true quantities for the secret sauce have never been fully known, but a bit of recipe testing should help to create the perfect formula for making the Jack in the Box sauce at home. According to The Infinite Kitchen, there are six main ingredients for getting that perfect flavor combination. It starts with three basic condiments — a mixture of ketchup, mustard, and mayonnaise.

From there, two other sauces are added: A1 Steak Sauce and Worcestershire sauce. (It's unclear, though, if the chain uses the A1 name brand or a similar sauce.) Plus, hot sauce gets mixed to add a kick. Finally, The Infinite Kitchen reports that dehydrated onion is added for additional flavor, as well as Xanthan gum, which generally acts as a thickener and binder, according to Healthline.

Though the ratios of each ingredient aren't known, the sauce is the type of recipe that can be prepared according to taste. Those making it at home might want to use even amounts of mild flavors like ketchup and mayonnaise, and less of the more powerful flavors, such as mustard, Worcestershire, and hot sauce.
