Smashburger Smashsauce

There is a wonderful thing going on in the restaurant world, an that would be the revitalization of the hamburger. It seems like places are finally giving the hamburger the respect that it deserves. Smashburger is one of my favorite places to get a hamburger, and they have this sauce, the Smashsauce, that is hard to beat.

Smashburger Smashsauce

The Smashsauce is a great sauce for your next burger.


  • Yield: approximately 3/4 cup.
  • 1/2 cup mayonnaise
  • 1/4 cup yellow prepared mustard
  • 2 teaspoons pickle juice
  • 2 teaspoons chopped dill pickle
  • 1 teaspoon vegetable oil


In a small bowl combine chopped dill pickles, mayonnaise, yellow mustard, and 2 teaspoons of dill pickle juice. Stir well, and let rest in the refrigerator for a couple of hours before serving. Yellow prepared mustard, is the normal mustard that you would have on any hot dog or hamburger. The dill pickle juice is critical for the recipe, the sauce has a sour tang, but not too many pickles, so this is how we get this wonderful dill flavor. A touch of vegetable oil is needed because the sauce is thin, and you can't really thin this one with water.

This sauce is perfect on a hamburger, and makes a wonderful sauce to dip your french fries into.

    sounds like tatar sauce.

      I can see that, it is a souped up mustard.

    I made this and it had a very strong taste of the French’s Mustard. Is 1/4 cup too much for the mustard?

    • stephaniemanley

      I didn’t think so. I do like mustard.

    Just so you know as a former Smasher, you have almost the exact recipe short of the lemon juice. That is what gives it that extra tang. And according to th e founder of Smashburger, French’s mustard is the only mustard allowed in smashsauce.

      My bad, the dill pickle juice is not in real smashsauce, just lemon juice

    I don’t know about the recipe above, but If the it’s the same smash sauce I had yesterday, it’s missing the horseradish I tasted in the sauce.

    • Stephanie

      I have never detected horseradish in there, I have detected a lot of sharp yellow mustard though.
