Make this creamy, tangy, and slightly smoky sauce in under 10 minutes using common pantry ingredients. It is the best sauce for smash burgers and works well as a dip for fries.
Gather all your ingredients. You do not need to cook anything for this recipe.
In a small bowl, combine the mayonnaise, ketchup, yellow mustard, pickle relish (or juice), smoked paprika, onion powder, garlic powder, and white vinegar.
Whisk the ingredients together until the sauce is completely smooth and uniform in color.
Taste the sauce. Add a pinch of salt and black pepper as needed. If you prefer more tang, add a few drops more vinegar or pickle juice.
Cover the bowl and chill the sauce in the refrigerator for at least 15 minutes before serving. This allows the flavors to meld together.
Use this sauce generously on your smash burgers, or serve it as a creamy burger dip for fries.
Notes
For a copycat flavor similar to popular fast-food sauces, increase the pickle relish slightly or add a tiny dash of sugar.
If you are planning meals for the week, this sauce keeps well in an airtight container in the refrigerator for up to one week. It is a great alternative to relying on meal delivery companies for quick flavor.
If you want a spicier sauce, add 1/4 teaspoon of cayenne pepper or a dash of your favorite hot sauce.
