Mustard potato salad is a classic and simple side dish for any occasion. With protein-rich eggs and delicious creamy dressing, you’ll make this salad often!
I love simple potato salad and this is, by far, my all time favorite recipe for it.
There is a secret ingredient I use that makes all the difference in the flavor!
Ingredients for mustard potato salad with egg
As with any potato salad, the first thing you’ll need are potatoes. If you scroll down to the recipe notes section, you’ll find some information about the best potatoes to use.
For the dressing:
- sweet onion – Red or yellow onion are both good choices
- dill pickles or pickle relish – For a sweeter flavor, you can swap the dills for sweet pickle relish.
- mayonnaise – If you want to cut down on the fat and calories, you can use light mayo or Greek yogurt
- yellow mustard – This is the best choice for the mustard in your salad. The flavor isn’t as strong as darker, grainy mustard can be.
- pickle juice – This is my secret ingredient to the best mustard potato salad! The pickle brine adds SO much flavor!
- coarse Kosher salt
- black pepper
- sugar – There isn’t much sugar in the recipe but if you want to omit it, you can. The sugar helps balance the flavors from the mustard and pickles.
Hard boiled eggs are the only other ingredient you’ll need for this recipe.
You can cook them using whatever method you like.

Helpful Kitchen Tools
Here are a few things that you’ll need to make this simple potato salad recipe. This equipment is the same kind that I use in my kitchen.
- What type of potatoes are best for potato salad?
There are two varieties of potatoes; waxy and starchy. Waxy potatoes, which have thin skin and firm flesh, are best for potato salad. This is because they hold up better after cooking.
Examples of waxy potatoes that would be perfect for this simple potato salad recipe are baby red potatoes, or yellow “Yukon gold” potatoes.
- How far ahead can you make potato salad?
This salad gets better the longer it sits in the fridge, so feel free to make it a day in advance. If you don’t want to make it that far ahead, plan well because it does need some chilling time.
- Does potato salad with egg need to be refrigerated?
Because of the mayonnaise and eggs in it, this mustard potato salad must be kept in the refrigerator.
It can safely be kept at room temperature for 3 to 4 hours, but if you’re serving it in a warm location, it must be kept on ice.
Also, to prevent any chance of illness, use a kitchen thermometer to check the temperature every 30 minutes. The temperature must kept below 40 degrees to prevent bacteria from growing.
