You need this quick and easy smash burger sauce recipe to achieve that creamy, tangy, restaurant-quality flavor on your homemade burgers. It takes less than five minutes to mix up using simple pantry staples.

Ingredients

Scale
  • 1/2 cup Mayonnaise
  • 2 tablespoons Ketchup
  • 1 tablespoon Sweet Pickle Relish
  • 1 teaspoon Yellow Mustard
  • 1 teaspoon White Vinegar
  • 1/2 teaspoon Smoked Paprika
  • 1/4 teaspoon Garlic Powder
  • 1/8 teaspoon Onion Powder
  • Pinch of Black Pepper

Instructions

  1. Gather all your ingredients. You will need a small bowl for mixing.
  2. Add the mayonnaise, ketchup, sweet pickle relish, yellow mustard, and white vinegar to the bowl.
  3. Measure and add the smoked paprika, garlic powder, onion powder, and black pepper.
  4. Use a whisk or a fork to mix all the ingredients together until the sauce is completely smooth and uniform in color.
  5. Taste the sauce. If you want more tang, add a few drops more vinegar.
  6. For the best flavor, cover the bowl and chill the sauce in the refrigerator for at least 15 minutes before serving. This lets the flavors meld together.
  7. Use this sauce generously on your smash burgers, or serve it as a burger dipping sauce for fries.

Notes

  • This sauce is fantastic as a spread for any sandwich, not just burgers.
  • If you do not have sweet pickle relish, you can substitute it with finely minced dill pickles and a tiny pinch of sugar.
  • For a slightly smoky and zesty burger spread, increase the smoked paprika to 3/4 teaspoon.
  • You can make this sauce ahead of time; it keeps well in an airtight container in the refrigerator for up to one week.
