Creamy Potato Salad

This classic Creamy Potato Salad is perfectly seasoned, incredibly rich, and guaranteed to be the star of your next summer cookout.

Why This Recipe Works:

• Warm Acid Infusion: Splashing the hot potatoes with vinegar allows the acid to penetrate the starch matrix before it locks up.
• Waxy Potato Selection: Using Yukon Gold potatoes ensures a creamy texture that holds its shape without turning into gluey mashed potatoes.
• Balanced Emulsion: Combining mayonnaise with sour cream and Dijon mustard prevents the dressing from breaking and becoming greasy.

My first real kitchen disaster happened during a humid July cookout when I was twenty, trying to impress my future in-laws with a massive bowl of potato salad. I ended up serving a bowl of cold, crunchy rocks swimming in a greasy pool of warm mayonnaise.

My mother-in-law politely ate two bites, but the look on her face told me everything.

I tested this with six different potato varieties and found that waxy red potatoes or Yukon Golds are hands down the best choice because they hold their shape without turning into mush. If you prefer a smokier, heartier version with bacon, you might want to check out our Steakhouse Potato Salad, but for a classic, creamy version, Yukon Golds are absolutely perfect.

The physics of this is fascinating.

By tossing the hot potatoes with apple cider vinegar and a generous pinch of Diamond Crystal kosher salt, you create a seasoned foundation before the creamy dressing even touches the spuds.

This pairs beautifully alongside classic cookout sides like our Creamy Coleslaw for the ultimate summer spread.

Ingredients

• 2 lbs (900g) Yukon Gold potatoes, peeled and cut into 3/4-inch cubes
• 1 tablespoon apple cider vinegar
• 1.5 teaspoons Diamond Crystal kosher salt, divided
• 1/2 cup mayonnaise
• 1/4 cup sour cream
• 1 tablespoon Dijon mustard
• 1/2 cup finely diced celery
• 1/4 cup finely diced red onion
• 2 hard-boiled eggs, chopped
• 2 tablespoons chopped fresh dill
• 1/4 teaspoon freshly cracked black pepper

Directions

1. Place the cubed potatoes in a large pot and cover with cold water by at least an inch. Add 1 teaspoon of Diamond Crystal kosher salt. Bring to a boil over high heat, then reduce to a simmer and cook until the potatoes are easily pierced with a paring knife, about 10 to 12 minutes.
2. Drain the potatoes thoroughly in a colander. While they are still steaming hot, transfer them to a large bowl and immediately drizzle with the apple cider vinegar. Gently toss with a rubber spatula and let cool for 15 minutes.
3. In a medium bowl, whisk together the mayonnaise, sour cream, Dijon mustard, remaining 1/2 teaspoon of salt, and black pepper until smooth.
4. Add the diced celery, red onion, chopped hard-boiled eggs, and fresh dill to the cooled potatoes. Pour the dressing over the top.
5. Fold everything together gently using a rubber spatula until the potatoes are evenly coated. Cover and refrigerate for at least 4 hours before serving to let the flavors meld.

Notes

• Salt Conversion: 1.5 teaspoons of Diamond Crystal kosher salt equals about 3/4 teaspoon of standard fine table salt or sea salt; adjust accordingly if swapping brands.
• The Potato Science: Yukon Gold potatoes contain less starch than Russets, meaning they won't break down into a gluey, pasty texture when folded with the heavy dressing.
• Workflow Warning: Do not let the cooked potatoes sit in the warm water after boiling, or they will waterlog and turn soggy; drain them immediately to keep them firm.
• Storage Behavior: After 24 hours in the fridge, the potatoes will absorb some of the moisture from the dressing, making the salad slightly thicker and more cohesive.

Serving Suggestions

This creamy side dish is incredibly versatile and pairs beautifully with almost any grilled main course. Here are a few of our favorite ways to serve it at your next backyard gathering:

• Serve it next to smoky Grilled BBQ Ribs for the ultimate summer feast.
• Pair it with juicy Turkey Burgers for a lighter backyard lunch.
• Add some charred Balsamic grilled vegetables with a touch of garlic flavor to round out the plate.
• Serve it alongside crispy Ranch Garlic Parmesan Chicken Skewers for a crowd-pleasing dinner.

Storage and Reheating

Potato salad is one of those rare dishes that actually tastes significantly better the next day. As it sits in the fridge, the potatoes continue to draw in the seasoned dressing, mellowing the sharp bite of the raw red onions.

However, because of the mayonnaise and sour cream base, you must keep it chilled. Never let it sit out at room temperature for more than two hours during a backyard barbecue.

Trust me, food safety is non-negotiable here.

Store any leftovers in an airtight glass container for up to four days. Do not freeze this salad under any circumstances, as the emulsion in the mayonnaise will break upon thawing, leaving you with a watery, separated mess.

Ingredient Substitutes

If you need to make a few quick adjustments based on what is currently in your pantry, here are the easiest swaps:

1. Mayonnaise: Swap half of the mayo for Greek yogurt if you want a tangier, lighter dressing.
2. Apple Cider Vinegar: White wine vinegar or fresh lemon juice works beautifully if you are out of apple cider vinegar.
3. Yukon Gold Potatoes: Red potatoes are an excellent alternative; just avoid starchy baking potatoes.
4. Fresh Dill: If you don't have fresh dill, you can use chopped fresh chives or flat-leaf parsley.

Go ahead and whip up a batch of this creamy potato salad for your next gathering, and watch it disappear. Just remember to salt your water, dress them warm, and enjoy the sunshine!
