Southern Potato Salad Recipe

This Southern Potato Salad Recipe is creamy, tangy, lightly sweet, and loaded with tender potatoes, hard-boiled eggs, crunchy celery, sweet pickle relish, and a mayonnaise-mustard dressing. It's the kind of classic cookout side dish that belongs next to pulled pork, smoked ribs, baked beans, coleslaw, burgers, and grilled chicken.

I love this recipe because it has that old-fashioned, family gathering feel without being complicated. Boil the potatoes and eggs, stir together the dressing, fold everything together, and let it chill until the flavors come together.

Whether you're making it for Memorial Day, July 4th, Labor Day, a backyard BBQ, or Sunday dinner, this Southern-style potato salad is always one of the first sides to disappear.

Why this Recipe Works

• Classic Southern flavor: Mayonnaise, mustard, sweet relish, vinegar, celery, onion, and hard-boiled eggs give this potato salad that familiar cookout flavor.
• Creamy but not soupy: Slightly tender potatoes absorb the dressing while still holding their shape.
• Great make-ahead side: Potato salad tastes even better after chilling, which makes it perfect for potlucks and BBQs.
• Simple ingredients: This recipe uses pantry staples and easy-to-find ingredients.
• Perfect for cookouts: It pairs with smoked meats, grilled chicken, burgers, hot dogs, fried fish, and just about every summer BBQ main.

Ingredient Notes

• Potatoes: Yukon Gold, russet, or white potatoes all work well for Southern potato salad. Yukon Gold potatoes have a creamy texture and hold their shape nicely, while russets break down a little more and make the salad extra creamy.
• Hard-boiled eggs: Chopped hard-boiled eggs are a must for classic Southern potato salad. They add richness and help give the salad that old-fashioned flavor.
• Celery: Celery adds crunch and freshness. Dice it small so it blends evenly through the potato salad.
• Sweet pickle relish: Sweet relish adds tang, sweetness, and a classic Southern-style flavor. Dill relish can be used if you prefer a less sweet potato salad.
• Mayonnaise: Mayo makes the dressing creamy. Duke's, Blue Plate, or Hellmann's all work well.
• Mustard: Yellow mustard gives the salad its classic color and tang. Dijon can be used for a sharper flavor.
• Apple Cider Vinegar: A little vinegar brightens the dressing and keeps the salad from tasting too heavy.
• Onion: Finely diced onion adds savory flavor. Sweet onion or yellow onion both work, and green onion is a milder option.
• Paprika: A sprinkle of paprika on top gives the potato salad a classic finished look.

How to Make Southern Potato Salad

1. Cook the potatoes: Add the peeled and chopped potatoes to a large pot and cover with cold water. Season the water generously with salt, then bring to a boil. Cook for 10 to 15 minutes, or until the potatoes are fork-tender but not falling apart.
2. Drain and cool: Drain the potatoes well and spread them out on a baking sheet or large plate to cool for a few minutes. Letting the steam escape helps keep the potato salad from getting watery.
3. Make the dressing: In a large mixing bowl, stir together the mayonnaise, mustard, vinegar, sweet relish, salt, pepper, and sugar.

4. Add the mix-ins: Add the chopped eggs, celery, onion, and slightly cooled potatoes to the dressing.
5. Fold gently: Gently fold everything together until the potatoes are evenly coated. Some of the potatoes may break down a little, which helps make the salad creamy.

6. Chill before serving: Cover and refrigerate for at least 1 hour, or until fully chilled. Stir gently before serving.
7. Garnish and serve: Sprinkle with paprika and add chopped parsley or green onion if desired.

Best Potatoes for Southern Potato Salad

Yukon Gold potatoes: These are my favorite choice because they're naturally creamy and hold their shape well.

Russet potatoes: Russets are starchier and break down more easily, which gives potato salad a softer, creamier texture.

White potatoes: White potatoes are a classic choice and hold their shape well after boiling.

Red potatoes: Red potatoes can work, but they have a firmer texture and are less traditional for this style of creamy Southern potato salad.

For the best texture, cook the potatoes until they are tender but not completely falling apart. You want some creamy edges, but not mashed potatoes.

How to Keep Potato Salad from Getting Watery

Potato salad can get watery if the potatoes are overcooked, not drained well, or mixed while they are still too hot and steamy.

• Drain well: Let the potatoes sit in the colander for a minute or two after cooking.
• Steam dry: Spread the potatoes on a baking sheet or plate for a few minutes so excess moisture can evaporate.
• Cool slightly before mixing: Warm potatoes absorb dressing well, but steaming-hot potatoes can loosen the mayonnaise.
• Do not overcook: Potatoes that are too soft can break down and release extra moisture.
• Stir before serving: If a little liquid collects after chilling, give the salad a gentle stir before serving.

What to Serve with Potato Salad

Southern potato salad is a classic side dish for cookouts, potlucks, picnics, and BBQ dinners.

Serve it with:

• Smoked Pulled Pork
• Smoked St. Louis Spare Ribs
• Grilled Chicken Legs
• Smoked Whole Chicken
• Smoked Chuck Roast

• Smoked Gouda Mac and Cheese

Storage Instructions

Store Southern potato salad in an airtight container in the refrigerator for 3 to 4 days. Keep it chilled until ready to serve, especially for cookouts and summer holidays.

I do not recommend freezing potato salad. The potatoes can become grainy, and the mayonnaise-based dressing can separate after thawing.

For parties, do not leave potato salad sitting out at room temperature for more than 2 hours, or more than 1 hour if it is very hot outside.

Make-Ahead Tips

Southern potato salad is a great make-ahead side dish because the flavor improves after chilling.

• Best timing: Make it 4 to 24 hours before serving.
• For parties: Make the potato salad the day before, then stir before serving and add the paprika garnish at the end.
• If it seems dry: Stir in a spoonful or two of mayonnaise before serving.
• If it seems too thick: Add a small splash of pickle juice, vinegar, or milk to loosen the dressing.
