Potato Salad Recipe Using Sour Cream: Creamy Tang with Fresh Dill

There’s nothing quite like a creamy potato salad to elevate a meal, and this version with sour cream delivers a tangy richness that’s hard to beat.

I developed this recipe after years of testing, focusing on the perfect balance between the sour cream’s acidity and the potatoes’ natural sweetness. Fresh dill adds a bright, herbaceous note that ties everything together.

What results is a salad with tender potatoes coated in a smooth, velvety dressing, with just enough texture from crisp vegetables. It’s the kind of dish that disappears fast at gatherings.

Perfect for summer picnics or as a side to grilled favorites. This recipe keeps well, making it ideal for preparing ahead.

Ingredients for Potato Salad Recipe Using Sour Cream

Creamy potatoes meet tangy dressing with fresh herbs for classic picnic perfection.

The potatoes are everything here. Yukon Golds strike the perfect balance—creamy texture without falling apart. Whole Foods or local markets often carry the best selection. Look for firm, unblemished spuds (about 1.5 inches in diameter) for even cooking. The sour cream must be full-fat—low-fat versions won’t emulsify properly with the mayonnaise, leading to a watery dressing that separates.

No fresh dill? Dried dill at one-third the amount works in a pinch, but the flavor won’t be as vibrant. For the celery, fennel bulb adds a similar crunch with a slight anise note. If avoiding eggs, replace with 0.5 cup diced avocado for creaminess. The Dijon can be swapped for whole-grain mustard if you prefer more texture. Always taste before final seasoning—potatoes absorb salt differently.

This keeps beautifully in the fridge for 3-4 days. Store in an airtight container with plastic wrap pressed directly on the surface to prevent browning. The flavors actually improve overnight as the dressing soaks into the potatoes. For best results, add the hard-boiled eggs just before serving (they can turn rubbery if stored too long in the dressing).

Step-by-Step Instructions for Potato Salad Using Sour Cream

Master this technique for perfectly creamy, tangy potato salad with optimal texture and balance.

Step 1: Prepare and Cook the Yukon Gold Potatoes

Peel the 2 lb Yukon Gold Potatoes and cut them into uniform ¾-inch cubes. I maintain consistent sizing to ensure even cooking and a professional presentation in the final dish. Place the cubes in a large pot and cover with cold water by 1 inch.

Add 1 tablespoon of the 1.5 tsp Kosher Salt to the water and bring to a boil over high heat. Reduce to a simmer and cook for 8-10 minutes until the potatoes are fork-tender but still hold their shape. Drain immediately and spread on a baking sheet to cool completely—this prevents the potatoes from turning mushy when dressed.

Step 2: Create the Creamy Sour Cream Dressing Base

In a large bowl, whisk together the 1.5 cups Full-Fat Sour Cream, 0.5 cup Mayonnaise, 2 tbsp Dijon Mustard, 1 tbsp White Vinegar, remaining ½ tsp Kosher Salt, and 1 tsp Freshly Ground Black Pepper until smooth. The vinegar brightens the richness of the sour cream, while the mustard adds depth of flavor.

I always use full-fat sour cream for this application—lower fat versions can make the dressing watery and less luxurious. Let the dressing sit for 5 minutes to allow the flavors to meld before combining with the other ingredients.

Step 3: Combine Vegetables and Eggs for Texture

In a separate bowl, combine the 0.25 cup Fresh Dill, 0.5 cup Green Onions, 0.75 cup Celery, 0.25 cup Yellow Onion, and 0.25 cup Sweet Pickle Relish. The celery adds essential crunch, while the pickle relish contributes subtle sweetness that balances the dish.

Chop the 4 whole Hard-Boiled Eggs into ¼-inch pieces and fold them into the vegetable mixture. I prefer to keep the eggs slightly chunky for visual appeal and textural contrast against the creamy potatoes.

Step 4: Assemble and Chill for Optimal Flavor

Add the cooled potatoes to the dressing and fold gently with a silicone spatula to avoid breaking the cubes. Then incorporate the vegetable-egg mixture, distributing everything evenly throughout the salad.

Cover the bowl with plastic wrap and refrigerate for at least 2 hours, though 4 hours is ideal. This chilling time allows the potatoes to absorb the dressing fully and the flavors to develop completely. The final texture should be creamy with distinct vegetable pieces in every bite.

Dietary Considerations for These Flavors

Gluten-Free Friendly

This dish is naturally gluten-free, making it perfect for those with celery sensitivity or wheat allergies. Just ensure your Dijon mustard and pickle relish are certified gluten-free to avoid hidden sources. I always check labels at my local Italian specialty deli for safe options. 💪

Vegetarian Adaptation

The base recipe is already vegetarian, but you can easily make it vegan by swapping the sour cream for coconut yogurt and omitting the eggs. The creamy texture remains intact, though the flavor profile shifts slightly. I’ve found Kite Hill brand works beautifully here.

Lower-Calorie Version

For a lighter take, use low-fat sour cream and Greek yogurt in place of mayonnaise. This reduces calories while keeping the tangy richness. Add extra fresh dill or celery to bulk it up without extra fat. The texture stays creamy, and the flavor remains vibrant.

Egg-Free Option

If avoiding eggs, replace them with ½ cup diced avocado for creaminess and healthy fats. The avocado adds a buttery texture that complements the potatoes well. Alternatively, chopped cucumber provides a refreshing crunch without altering the dish’s character.

Allium Alternatives

For those sensitive to onions, swap the green onions and yellow onion for fennel bulb. It delivers a similar crunch with a mild anise note. I often use this trick at Sunday family dinners to accommodate everyone’s preferences. ✨

Dairy-Free Adjustments

To make this dairy-free, replace the sour cream with unsweetened coconut yogurt or cashew cream. Both provide a tangy, creamy base that works well with the other ingredients. I recommend So Delicious brand for the best texture.
