Ingredients You’ll Need
This recipe relies on a handful of simple, wholesome ingredients that come together to create a deliciously balanced potato salad. Each component is essential, offering texture, flavor, or richness that elevates the whole dish.

- 1 1/2 cups mayonnaise (or Miracle Whip): Delivers the creamy, luscious texture the salad is known for.
- 2 tablespoons yellow mustard: Adds just the right tang and depth of flavor.
- 1/4 cup pickle juice: Infuses the salad with an extra layer of zesty acidity.
- 1/4 cup cream or half and half: Lightens the dressing for a perfect silky finish.

How to Make Nan’s Classic Mustard Potato Salad Recipe
Step 1: Boil Potatoes and Eggs
Begin by boiling the russet potatoes whole with their skins on alongside the eggs. This method helps keep the potatoes from becoming waterlogged while cooking, preserving their texture for dicing.
Step 2: Remove Eggs and Potatoes at the Right Time
Pull the eggs out after 10 minutes to ensure a perfect hard boil, then let the potatoes continue until they’re just fork tender to avoid mushy pieces in the final salad.
Step 3: Cool Them Down Completely
Place the eggs and potatoes on the counter until they reach room temperature, then peel and refrigerate both until they are cold. Cold potatoes dice more cleanly and hold their shape better.
Step 4: Dice Potatoes and Crumble Eggs
Cut the potatoes into small 1/4 to 3/8 inch cubes for an ideal bite size. Crumble the eggs by gently squeezing them in your hand for a rustic texture that spreads throughout the salad.
Step 5: Add the Finely Chopped Veggies
Finely dice the onions, celery, and dill pickles to create those fresh bursts of flavor and slight crunch in every spoonful. Add them directly to the container with the potatoes and eggs.
Step 6: Prepare the Creamy Dressing
In a separate bowl, whisk together the mayonnaise, yellow mustard, pickle juice, cream, salt, white pepper, and sugar until creamy and smooth. This dressing is the heart of Nan’s Classic Mustard Potato Salad Recipe, lending it that distinct tangy richness.
Step 7: Combine and Chill
Pour the dressing over the potato mixture and gently stir until every piece is lightly coated. Cover the container and refrigerate for at least 4 hours, though waiting 6 to 8 hours or overnight makes the flavors meld beautifully.
Step 8: Optional Finishing Touch
Before serving, sprinkle a pinch of sweet paprika over the top for an inviting pop of color and subtle smoky note that makes this salad even more irresistible.

Creative Ways to Present

Make Ahead and Storage
Storing Leftovers
Leftover potato salad can be kept in an airtight container in the refrigerator for up to 3 days. Keep it chilled and covered to preserve freshness and flavor, giving it a quick stir before serving again.
Freezing
This potato salad is best enjoyed fresh or refrigerated; freezing is not recommended as the potatoes and creamy dressing can become watery and lose their texture once thawed.
Reheating
Nan’s Classic Mustard Potato Salad Recipe is meant to be served cold, so reheating isn’t necessary. Just bring it out of the fridge about 10 minutes before serving to take the chill off for a softer texture.
FAQs
Can I use a different type of potato in this salad?
Russet potatoes are ideal because they hold their shape well when boiled, but Yukon Golds can also work if you prefer a creamier texture. Just be gentle when mixing to avoid mushiness.
Is Miracle Whip really better than mayonnaise?
Miracle Whip offers a slightly sweeter and tangier flavor compared to traditional mayonnaise, which some folks, including Nan herself, prefer in this salad for its distinctive taste. However, either works well depending on your preference.
Can I make this salad vegan or dairy-free?
While this recipe relies heavily on eggs and dairy-based mayo, you could experiment with vegan mayonnaise and omit eggs, but the classic flavor and texture will change quite a bit.
Why is it important to refrigerate the potatoes before dicing?
Chilling the potatoes allows them to firm up, making it easier to dice neatly without breaking them apart. This step helps maintain the salad’s appealing texture.
How long can I prepare this salad ahead of time?
For best flavor, prepare it the day before and refrigerate for at least 6 hours. This rest time allows the ingredients to meld and the dressing to soak into every bite beautifully.

Nan’s Classic Mustard Potato Salad Recipe is truly a comforting, classic dish that brings people together with its familiar flavors and perfect balance of creamy, tangy, and crunchy elements.
