Adjust seasonings with salt and pepper. Use or cover and chill the sauce.
Notes
The secret to the best burger sauce is letting it rest. While you can use it immediately, I always chill it for at least 15 to 30 minutes. This gives the flavors time to meld and mingle, creating a more cohesive, well-balanced flavor profile. Trust me, this short wait makes all the difference.Finely dice the pickles and onions: They’ll be distributed evenly in the sauce. If you prefer a smoother texture, you can finely grate the pickles and onion or even pulse everything in a food processor or blender for a few seconds.Experiment with the flavors: For an extra kick, add a dash of smoked paprika, cayenne pepper, hot sauce, or a spoonful of minced pickled jalapenos. For a more herbaceous note, try adding a sprinkle of dried parsley, dill, or chives.For a lighter twist: If mayonnaise isn’t your thing, try swapping it out for Greek yogurt. It isn’t as heavy and will add some sneaky protein, too. Or, if some of your guests don’t eat eggs, make the burger sauce with vegan mayonnaise instead.Make-Ahead: Make a batch in advance and store it in an airtight container in the fridge until you’re ready to use it. It tastes even better after sitting for a day or two!How to Store: Keep the sauce in an airtight jar or container in the refrigerator for up to 1 week. If it thickens too much in the fridge, thin it with a splash of vinegar, pickle brine, or a little water.
