What Is Smash Sauce?

The burgers are Smashburger are something else. And it’s undoubtedly the sauce that really sets them apart. But what is this smash sauce? What ingredients are in there, what does it taste like and how do you make your own? Well, you’ve come to the right place.

So, what is Smash sauce? Smash sauce is a blend of mayonnaise, french mustard, chopped dill pickles (or pickle relish), and lemon juice. The quantity of each ingredient has a big impact on its resulting taste, and some experimentation of proportion is required to get the authentic taste of this crowd-pleasing sauce.

Sounds delicious right?

And it really is!

And while it sounds like a secret recipe, there is nothing particularly challenging to get nor is there a never-ending list of ingredients that make it up.

Nevertheless, it’s the quantities of each ingredient that counts here.

So let us now take a closer look at a simple recipe if you were looking to make your own.

Smash Sauce

This creamy sauce with a kick is perfect for any burger.

Prep Time 5 minutes
Additional Time 2 hours
Total Time 2 hours 5 minutes


  • 1/2 Cup of Fresh Mayonnaise,
  • 1/8 Cup of Yellow, French Mustard (the Frenches brand only)
  • 2 Teaspoons of chopped Dill Pickles,
  • 2 Teaspoons of Lemon Juice
  • 1/2 Teaspoon of Olive Oil


  1. In a small bowl, combine all the ingredients together.
  2. Stir and store in the fridge for a 2-3 hours before serving.

That is literally it.

So simple.

And while these quantities of ingredients make for the classic Smash sauce, feel free to change them up a little to find what works for you.

You may like more mustard, for instance.

Olive Oil is certainly required though; it gives the sauce the right amount of consistency and makes it much more easily spread.

What Does Smash Sauce Taste Like?

Smash sauce tastes similar to burger sauce. It’s relatively creamy (from the mayonnaise) but it has a bit of a kick from the mustard, pickles, and lemon juice.


Smash sauce is certainly a winner.

No wonder why it’s a staple in pretty much every Smashburger on the menu.

And thankfully, it’s very easy to make at home yourself.

And while I would wholeheartedly recommend French Mustard (from the French brand specifically), there is no reason why you cannot experiment with different mustard options.

Find what you like, and give it all a try.

On different occasions, of course.

Or perhaps not if you are feeling particularly adventurous.
