An Easy, Classic Smashburger Sauce Made With Pantry Ingredients
What is in smashburger sauce?
While Shake Shack won’t reveal their *exact* recipe for the shack sauce, according to Bon Appetit, they reveal a rough template to work off of. Their recipe calls for: 1/2 cup Hellman’s mayonnaise, 1 Tbsp. Dijon mustard, 3/4 tsp. Heinz ketchup, 1/4 tsp. kosher dill pickling brine, and a pinch of cayenne pepper.
I started with their base recipe but adjusted the ratios to my own taste preference. For example, I upped the ketchup and pickle brine, and I seasoned generously with salt and pepper. Otherwise, the recipe is quite similar.
Let’s talk about what makes this recipe special:
My version is just as easy and straightforward — and it’s infinitely customizable. When researching this recipe, I noticed several other online versions including other ingredients, such as Worcestershire sauce or finely chopped pickles. I like to keep it simple, but you can absolutely change it up as you like. I debated adding finely chopped pickles for a bit of texture, but because I typically add pickles in my own smashburger recipe, I didn’t feel this was necessary.

- Dijon Mustard: A bit of dijon mustard adds a little bit of spice and tang.
- Ketchup: Ketchup imparts a light pink hue to the sauce, while also providing sweetness and umami.
- Dill Pickle Brine: The brine from a jar of dill pickles is salty and sour, and it helps contrast the fatty, creamy flavors of the mayonnaise. If you don’t have pickle brine, you can use lemon juice or apple cider vinegar.
