This creamy potato dish balances tender cubes of waxy potatoes with crisp celery, red onion, and scallions. The dressing blends mayonnaise, sour cream, Dijon mustard, apple cider vinegar, and fresh dill for a smooth, tangy finish. Optional hard-boiled eggs and pickles add texture and depth. Perfect chilled, this side complements grilled meats or picnic spreads with fresh, herbaceous notes and a satisfying creaminess.
There's something about the smell of dill that instantly transports me to my aunt's kitchen on a sweltering July afternoon, when she'd pull together a potato salad with almost no fuss, just intuition and whatever vegetables looked good at the market. She never measured anything precisely, but somehow it always turned out perfect—creamy, bright, and so refreshingly cold that we'd keep going back for thirds. I finally asked her the secret one summer, and she laughed, saying it was just good potatoes, patience with the dressing, and never being afraid of the fresh dill. Now I make it her way, and it's become the dish people request.
I once made this for a potluck where I didn't know anyone very well, and I was genuinely nervous about what to bring. But I chose this salad because I could make it the night before, and when I arrived, it was somehow the thing that sparked conversations—people asking about the dill, going back for seconds, one person even asking if I'd share the recipe. It was a quiet reminder that simple, honest food has a way of bringing people together.
Ingredients
- Waxy potatoes (Yukon Gold or red): These hold their shape when cooked, unlike starchy varieties that can turn mushy—the difference between a salad and potato soup.
- Mayonnaise: Use the real thing here; it's the creamy foundation that makes every bite worthwhile.
- Sour cream: This keeps the dressing from being too thick and adds a subtle tang that brightens everything.
- Fresh dill: Don't use dried; it loses all its delicate, herbaceous charm.
- Dijon mustard and apple cider vinegar: These add sharpness and prevent the salad from tasting one-note and heavy.
- Celery and red onion: They provide crunch and bite, keeping the texture interesting.
- Scallions: Scatter these over the top for a fresh, oniony brightness that announces itself in the best way.
Instructions
- Cook the potatoes until just tender:
- Cut your potatoes into 1-inch cubes so they cook evenly, then boil them in salted water for 10 to 12 minutes—you want them fork-tender but not falling apart. The moment they're done, drain them and let them cool just enough to handle.
- Build the creamy dressing:
- In a bowl, whisk together mayo, sour cream, mustard, vinegar, and dill until it's smooth and pale green with herb flecks. This is where the magic starts.
- Combine while potatoes are still warm:
- Add the cooled potatoes, celery, red onion, and scallions to the dressing and gently fold everything together—the warm potatoes will absorb the flavors much better than cold ones would.
- Fold in optional additions:
- If you're using hard-boiled eggs or pickles, add them now with a gentle hand so you don't crush anything.
- Let it rest in the refrigerator:
- Cover and chill for at least an hour so the flavors meld and deepen; this is where patience pays off.
- Taste and adjust before serving:
- Sometimes it needs a pinch more salt or a splash more vinegar; trust your palate, and finish with a sprinkle of fresh dill on top.
This salad became something more than just a side dish the year my partner and I decided to have an impromptu picnic in the park, armed with nothing but this, some bread, and cold drinks. We sat under a tree and realized we were happy in the simplest way—good food, sunshine, and no rush. That's when I understood why my aunt made this so often; it was never really about the recipe.
The Secret to Creamy Perfection
The combination of mayonnaise and sour cream is what sets this apart from other potato salads—mayo gives you the richness and body, while sour cream keeps it from feeling too heavy and adds a subtle tartness that makes you want another bite. I learned this the hard way by once trying to make it with only mayo, and it was dense and one-dimensional. The sour cream is the unsung hero that makes people ask for your recipe.
When to Serve It
This salad actually improves overnight, so make it a day ahead if you can—the flavors deepen and meld in the most satisfying way. It's the perfect companion to grilled chicken or fish, or honestly, it's substantial enough to be the main event alongside some crusty bread and cold beer on a warm evening.
Playing with Flavor
Once you nail the basic recipe, you can start experimenting without losing what makes it special. A pinch of smoked paprika adds a subtle earthiness, or try swapping the vinegar for white wine vinegar if you want something slightly more delicate. Some people add crispy bacon, hard-boiled eggs, or chopped pickles for texture and tang, and every addition feels like a natural evolution rather than a departure.
- For a lighter version, replace some or all of the mayo with Greek yogurt, though you'll lose a bit of that classic richness.
- Make it ahead and store it in the fridge for up to three days; it keeps beautifully and actually tastes better each day.
- Always taste and adjust the seasoning right before you serve it, because cold food sometimes needs a bit more salt and acid to sing.
This is the kind of recipe that tastes like home no matter where you are—dependable, comforting, and somehow always welcome at the table. Make it once and you'll understand why people keep asking you to bring it to every gathering.
