  • Comes together in minutes!
  • Uses common, easy-to-pronounce ingredients
  • Must have on homemade smash burgers

Featured Ingredients

ingredients for smash burger sauce.
  • Mayonnaise - Use a high-quality mayo. My favorite is one made with avocado oil. 
  • Ketchup - I use Simply Heinz Ketchup. It has no high fructose corn syrup. 
  • Worcestershire Sauce - Packs a ton of flavor in that one teaspoon.
  • Horseradish - Adds a wonderful spice and flavor. 
  • Smoked Paprika - Adds beautiful color and smokiness to the sauce.
  • Green Onions - Bring a bit of onion flavor to the sauce without overpowering it. 
  • Dill Pickles - Adds a bit of crunch and an excellent dill flavor.
  • Kosher Salt - Needed to bring all the flavors together.

See the recipe card for the exact measurements and complete instructions.

Step-By-Step Instructions

Step 3: Spread a layer of smash sauce on one side of a hamburger bun. Top with a burger patty or two.

Top with additional burger toppings, like cheese, lettuce, or tomatoes, and then add the top bun. 

Tips and Tricks

Make a double batch and dip French fries in it! Call it fry sauce. 

Whip up the smash sauce a few days in advance. The flavors meld together, and it gets even better!

Ingredient Swaps

  • Relish - Use pickle relish instead of dill pickles as a great shortcut.
  • Mustard - Add a teaspoon of Dijon mustard or yellow mustard.

Variations

Spicy Smash Burger Sauce: Add a pinch of cayenne pepper or a few drops of hot sauce for some spice. 

Low FODMAP Burger Sauce: Use a low FODMAP ketchup, like the option from Smoke and Sanity. Use only green onion tops and pickles without onion or garlic listed in the ingredients. For additional low FODMAP guidance, use the Monash University Food App.

Storing

Store: Keep smash burger sauce in an airtight container in the refrigerator for 3-4 days.

Freezer: I would not recommend freezing it. It would be better to make another batch if you need it later.
