Salads
This classic potato salad recipe with sour cream delivers the creamy, tangy texture that makes it a picnic and potluck staple. The secret lies in perfectly cooked potatoes tossed with a rich sour cream dressing that balances tangy and sweet notes—no mayo in sight.
I’ve perfected this version to stay creamy without turning greasy, with just the right amount of mustard and vinegar for depth.
What sets this recipe apart is the technique: boiling potatoes until tender but still holding their shape, then cooling them completely before mixing. This prevents a watery salad, and the sour cream dressing binds everything together for that signature creamy consistency.

By the time you’re done, you’ll have a potato salad with vibrant, bite-sized potatoes coated in a velvety dressing that’s tangy, slightly sweet, and perfectly balanced.

Serve it warm or chilled, alongside grilled meats or on its own. The recipe scales easily, so you can make it for a small family dinner or a large backyard barbecue. Let’s get started on this timeless classic!
Ingredients for classic potato salad recipe with sour cream
Sixteen ingredients for a potato salad that’s creamy, tangy, and always a crowd-pleaser.
| Ingredient | Amount | Notes |
|---|---|---|
| Yukon Gold Potatoes 🥔 | 2 ½ lb | Medium size, cut into 1-inch cubes |
| Sour Cream 🧀 | 1 cup | Full-fat for best creaminess |
| Mayonnaise 🥫 | ½ cup | For extra creaminess (optional) |
| Dijon Mustard 🍯 | 2 tbsp | For tangy depth |
| White Vinegar 💧 | 2 tbsp | For bright acidity |
| Granulated Sugar 🍚 | 1 tbsp | Balances tanginess |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Celery Stalk 🧅 | 1 whole | Finely diced, for crunch |
| Red Onion 🧅 | ¼ cup | Finely diced, for sharpness |
| Hard-Boiled Eggs 🥚 | 4 whole | Chopped for garnish |
| Fresh Dill 🌿 | 2 tbsp | Chopped, for freshness |
| Paprika 🌶️ | ½ tsp | Smoked for depth (optional) |
The potatoes are non-negotiable—Yukon Golds stay creamy without falling apart. Walmart or Kroger usually carry them year-round, but local farmers markets have them in season. Cut them into even 1-inch cubes so they cook uniformly. The sour cream is the star here—full-fat is a must for that velvety texture. I grab mine from Trader Joe’s because it’s consistently rich and tangy. For the eggs, room-temperature eggs peel easier, and always use ice-cold water for boiling to prevent cracking.
No sour cream? Greek yogurt at half the amount works in a pinch, though it’s tangier. Skip the mayo if you’re watching calories, but the salad will be slightly lighter. Apple cider vinegar swaps out white vinegar for a fruitier note. The celery and onion can be pre-chopped from the store (Trader Joe’s has great prepped veggies), but fresh is always brighter. For the dill, dried works at one-third the amount, but fresh is worth the extra minute. The sugar might seem odd, but it balances the acidity beautifully—trust me on this.
Potatoes reheat beautifully—just warm them gently with a splash of water to keep them moist. Store the dressing separately in the fridge for up to 3 days, then mix when ready to serve. The chopped eggs and herbs stay fresh for 2 days in the fridge, so add them last. This salad actually tastes better the next day as the flavors meld. For large gatherings, double the recipe—it’s that easy.
Why You'll Love This Recipe
- No Boil, No Stress: I swear by this method—just parboil the Yukon Golds, then let them finish in the dressing. No mushy potatoes, no peeling if you’re lazy (I am), and the creamy sour cream-mayo mix clings to every bite like it’s glued there.
- Tangy Creamy Magic: That splash of white vinegar and Dijon mustard? It’s the secret. The sour cream keeps it rich but not heavy, while the vinegar cuts through the fat—like a bright, cool summer day in your mouth. (Yes, even on a Tuesday night.)
- Picnic to Potluck: This salad’s my go-to for everything: backyard BBQs, lazy Sunday lunches, or when I need to feed a crowd without slaving away. Double the batch, and you’ve got leftovers for days—trust me, it tastes just as good cold tomorrow.
- Budget-Friendly Luxury: Yukon Golds are pricier than russets, but they’re worth it—they hold up better and taste buttery without extra fat. Sour cream and mayo stretch far, and a little vinegar goes a long way. Fancy enough for company, cheap enough for weeknights.
Step-by-step instructions for creamy potato salad
Here's the method that delivers that perfect balance of creamy, tangy, and fresh in every bite.
Cook Potatoes Until Fork-Tender
Place the 2.5 lb Yukon Gold potatoes in a large pot and cover with cold water by about 2 inches. Add 1.5 tsp of the salt and bring to a boil over high heat. Once boiling, reduce heat to medium and cook for 12-15 minutes until a knife slides in easily.
I like to test doneness by piercing with a sharp knife - the potatoes should be tender but not falling apart. Drain immediately and let them steam-dry in the colander for 2 minutes. This step is crucial for preventing a watery salad later. While still warm, cut the potatoes into 1-inch cubes as specified in the ingredients.
Prepare the Dressing Components
In a medium bowl, whisk together the 1 cup sour cream, 0.5 cup mayonnaise, 2 tbsp Dijon mustard, 2 tbsp white vinegar, 1 tbsp granulated sugar, and 0.5 tsp black pepper. This combination creates the perfect balance of tangy, sweet, and creamy flavors that make this salad classic.
For the vegetables, finely dice the 1 whole celery stalk and 0.25 cup red onion. Chop the 4 hard-boiled eggs into small pieces and set aside. The fresh dill and 0.5 tsp paprika can be chopped together and saved for the final step. Here's where you'll notice the difference - fresh dill adds brightness that dried herbs can't match.
Combine Everything for Perfect Texture
In a large mixing bowl, gently fold the warm potato cubes with the dressing mixture. Start with half the dressing and mix thoroughly, then gradually add the remaining dressing while continuing to fold. Be careful not to mash the potatoes - we want those individual cubes for texture.
Add the diced celery, red onion, and chopped eggs to the potato mixture. Fold everything together gently but completely. The potatoes should be fully coated in the creamy dressing. Here's the thing - the residual heat from the potatoes will help emulsify the dressing better than if you combined everything cold.
Chill and Finish with Fresh Herbs
Cover the bowl and refrigerate for at least 2 hours, preferably 4 hours. This chilling time allows all the flavors to meld together perfectly. The longer it chills, the creamier it becomes as the starches in the potatoes absorb the dressing.
Before serving, stir in the chopped fresh dill and paprika. This final step adds that fresh, vibrant finish that makes this salad truly special. The paprika adds just a hint of smokiness that complements the creamy texture beautifully. Serve chilled and enjoy this classic potato salad that's always a crowd-pleaser.
Pro Tips For Making Classic Potato Salad Recipe With Sour Cream
- Boil Potatoes Until Fork-Tender: I learned this the hard way—undercooked Yukon Golds turn to mush in the dressing. Test them at 180°F internal temp (or when a fork slides in like butter). Drain immediately and let them steam-dry for 2 minutes—this prevents a soggy salad later.
- Chill Dressing Before Mixing: Cold dressing = creamy salad. Whisk sour cream, mayo, mustard, and vinegar together, then refrigerate for 30 minutes before folding into potatoes. The chill keeps the texture stable, and you’ll avoid that weird grainy separation that happens when warm dairy meets cold potatoes.
- Skip the Vinegar Until Serving: Add white vinegar to the dressing last minute. It’s the acid that keeps the salad bright, but too early and it curdles the sour cream. Taste the base dressing first—if it’s bland, add 1 tsp vinegar right before mixing with potatoes.
- Cut Potatoes Warm, Toss Cold: Slice potatoes while still warm from boiling (they’ll be easier to handle), but let them cool completely before tossing in dressing. Warm potatoes release starch like crazy, turning your salad into glue. Cold potatoes absorb dressing evenly without falling apart.
Pro cooking tips for great classic potato salad recipe with sour cream
Potato Cooking Perfection
Boil your Yukon Gold potatoes in cold, salted water—never hot—to ensure even cooking. The water should cover them by 2 inches, and you’ll know they’re done when a knife slides in like butter.
I swear by 12-15 minutes on medium heat after boiling. Drain them immediately and let them steam-dry in the colander for 2 minutes—this step prevents a watery salad later. 🥔
Dressing Emulsification Trick
Warm the potatoes slightly before mixing with the dressing—just 1-2 minutes in the bowl will help the sour cream and mayo emulsify better. Start by folding in half the dressing first, then gradually add the rest.
This gradual approach prevents a greasy texture and ensures every potato gets coated evenly. The residual heat from the potatoes also helps the dressing cling beautifully.
Chilling for Creaminess
Never skip the 2-4 hour chilling time—this is where the magic happens. The starches in the potatoes absorb the dressing, creating that signature creamy texture. I like to cover the bowl with plastic wrap pressed directly onto the surface to prevent a skin from forming.
The longer it chills, the richer and more cohesive the flavors become.
Fresh Herbs at the End
Always add the fresh dill and paprika right before serving. These ingredients lose their vibrancy if mixed in too early. The dill adds a bright, fresh note that cuts through the richness, while the paprika gives a subtle smoky depth.
A quick toss with a fork right before serving keeps everything looking fresh and appetizing. ✨
Preventing Watery Salad
If your salad turns out watery, it’s usually because the potatoes weren’t dried enough after boiling or the dressing was added too soon. To fix it, drain the excess liquid by pressing the salad through a fine-mesh strainer or paper towels.
For future batches, always let the potatoes cool completely before mixing with the dressing—this helps the starches set properly.
Make-Ahead Pro Tip
This salad actually tastes better the next day as the flavors meld together. Store the dressing separately in an airtight container for up to 3 days, then mix it with the potatoes just before serving.
The chopped eggs and herbs can be stored separately for 2 days—add them fresh when ready to eat. This method keeps everything crisp and vibrant, even after chilling. 💡

Frequently asked questions
Why does this recipe use sour cream instead of mayo?
Sour cream creates a lighter, tangier texture that stays creamy without being heavy. Unlike mayo-based salads, this version has a bright acidity from the vinegar and a subtle sweetness from the sugar, making it perfect for warm weather. The sour cream also adds a velvety richness that mayo can't match.
Can I make this potato salad ahead of time?
In fact, it tastes even better the next day as flavors meld. Store the dressing separately in an airtight container for up to 3 days, then mix with cooled potatoes just before serving. Keep chopped eggs and herbs separate until serving to maintain freshness. The longer it chills, the creamier it becomes!
What if my potatoes turn out mushy? Mushy potatoes usually happen from overcooking or not drying them properly after boiling. For future batches, boil them just until fork-tender (12-15 minutes), drain immediately, and let them steam-dry in the colander for 2 minutes. Also,
Can I substitute Greek yogurt for sour cream?
Yes, but use half the amount of Greek yogurt and add 1 tbsp lemon juice to mimic sour cream's tang. The texture will be slightly lighter, but the flavor remains bright. For best results, choose full-fat yogurt to maintain creaminess. This swap works well if you're watching calories!
How do I prevent a watery potato salad?
The key is proper potato prep: boil in cold water, drain immediately, and let them steam-dry for 2 minutes before cutting. Also, wait until potatoes are completely cool before mixing with dressing. If your salad still seems watery, drain excess liquid by pressing through a fine-mesh strainer or paper towels.
