What Is Smash Sauce? [Find Out Here]

The burgers from Smashburger are not just regular burgers. And the sauce is undoubtedly what sets them apart and gives them an unusual flavor. This sauce is known as “smash sauce.”

This creamy sauce, balanced by a healthy amount of acidity, is the ideal accompaniment to the thin, crispy burgers. By the way, what is this creamy sauce? What ingredients are in it, what does it taste like and how can you make yours?

In this article, I will explain smash sauce, its uses, benefits, and other relevant information about it.

So, let’s get started.

What is smash sauce?

Smash sauce is a simple mayonnaise-based sauce, with a healthy portion of French mustard, chopped dill pickles (or pickle relish), salt, pepper, and pickle juice added for additional acidity.

A drop of vegetable oil brings the sauce together, and then it is refrigerated for at least four hours to allow the flavors to blend.

However, the final flavor of this unique sauce is quite sensitive to the proportions of each ingredient, so feel free to play with the amounts until you find the sweet spot of your liking.

Sounds scrumptious right? Yes, it is. It may have the air of a secret recipe, but none of the ingredients are particularly hard to come by, and there is not a never-ending list of them either.

What does smash sauce taste like?

Smash sauce tastes like burger sauce. It is creamy (thanks to the mayo), but it got a spike from the mustard, pickles, and lemon juice. However, in general, it tastes really good.

How to serve smash sauce

The best way to serve it is to apply it straight to the bread.

Half of the sauce should go on top of the bread and the other half to the bottom. This will not only spread the flavor evenly but also keep your bread from getting too wet.

Also, it goes well with all kinds of sandwiches, like classic deli-style sandwiches, grilled cheese, and even brats or hotdogs. You can as well put it on your French fries or crispy polenta fries as a fry sauce.

How to preserve smash sauce

Keep it refrigerated in a sealed container. The sauce should remain fresh for around two weeks.
