Red potato salad lands best when the potatoes stay tender but don’t fall apart, and the dressing clings in a light, creamy coat instead of turning heavy and gluey. This version keeps that balance by leaning on Greek yogurt for body and using just enough mayonnaise to round out the tang. The result is cool, bright, and substantial without feeling weighed down.
The trick is in the potatoes and the dressing ratio. Red potatoes hold their shape better than waxier varieties that collapse into the bowl, and that matters once you toss them with herbs and celery. Greek yogurt gives the salad a clean, fresh edge, while Dijon and white wine vinegar wake everything up so it tastes seasoned instead of flat. Letting it chill for a couple of hours is part of the recipe, not an afterthought; the dressing settles into the potatoes and the dill has time to bloom through the whole bowl.
The dressing was light but still creamy, and the potatoes held their shape after chilling. I loved that the dill and Dijon came through without the salad turning heavy.
Save this light red potato salad with Greek yogurt for cookouts, picnics, and easy sides that still taste creamy.
The Reason This Potatoes-First Salad Stays Creamy Without Turning Heavy
The biggest mistake in light potato salad is trying to replace mayo one-for-one with yogurt and hoping nobody notices. Yogurt brings tang and freshness, but by itself it can taste sharp and thin. The small amount of mayonnaise here smooths out the dressing, so it coats the potatoes instead of sliding off them, and Dijon helps tie the whole thing together with a little backbone.
Another thing that matters: don’t overwork the potatoes once they’re cooked. Red potatoes should be tender enough to pierce cleanly with a fork, but not so soft that they crumble into mash when tossed. If you drain them and let the steam escape before dressing them, they hold their shape better and absorb more flavor instead of watering the bowl down.
What Each Ingredient Is Actually Doing in This Bowl
- Red potatoes — Their waxy texture keeps the salad chunky and clean-looking after chilling. Russets turn fluffy and fall apart; that’s the wrong texture for this style.
- Greek yogurt — This is what makes the salad feel lighter without losing creaminess. Use plain yogurt with a thick texture, not a runny one, or the dressing can get loose after it sits.
- Mayonnaise — A small amount rounds out the tang from the yogurt and vinegar. If you skip it entirely, the dressing can taste a little too lean and sharp.
- Dijon mustard — Dijon adds depth and helps the dressing emulsify, so it clings better to the potatoes. Yellow mustard works in a pinch, but it tastes flatter.
- White wine vinegar — This keeps the salad bright and balanced. If you use apple cider vinegar, start with a little less because it reads sweeter.
- Dill, green onions, and celery — Dill gives the salad its fresh herb note, green onions add bite, and celery brings the crunch. Chop everything small enough that you get a little of each in every forkful.
How to Keep the Potatoes Tender, Not Mushy
Cooking the Potatoes to the Right Point
Start the potatoes in cold salted water and bring them up gently, then simmer until a knife slides in without resistance but the cubes still hold their edges. If the water is boiling hard the whole time, the outsides can break down before the centers are done. Drain them well and let them sit long enough for the steam to calm down; that dry surface helps the dressing stick later.
Mixing the Dressing Before It Hits the Bowl
Stir the Greek yogurt, mayonnaise, Dijon, vinegar, salt, and pepper together until the dressing looks smooth and loose enough to coat a spoon. If the yogurt is cold from the fridge and seems stubborn, whisk a little longer instead of dumping extra vinegar in. The dressing should taste a touch bold on its own because the potatoes will mellow it once everything chills.
Folding Everything Together
Add the potatoes, dill, green onions, and celery to a large bowl, then pour the dressing over the top and fold gently. If you stir aggressively, the cubes on the bottom will break and the salad turns pasty in spots. A wide spatula or big spoon works better than a whisk here because you’re coating, not beating.
The Chill That Pulls It All Together
Cover the bowl and refrigerate for at least 2 hours before serving. That resting time lets the potatoes absorb the seasoning and softens the sharp edge of the vinegar. If the salad seems a little tight after chilling, give it a quick stir and add a spoonful of yogurt before serving rather than thinning it with water.
Three Ways to Adjust This Salad Without Losing the Point
Make It Fully Mayo-Light
Use all Greek yogurt and skip the mayo if you want the cleanest, tangiest version. The dressing will be a little sharper and less silky, so add the mustard slowly and taste after chilling before deciding if it needs a pinch more salt.
Make It Dairy-Free
Swap the Greek yogurt for a thick dairy-free yogurt with a plain, unsweetened flavor. The result will be a little less rich and may need an extra spoonful of mayonnaise if you’re using it, because many dairy-free yogurts are thinner than the original.
Add Hard-Boiled Eggs for a Heartier Side
Chopped hard-boiled eggs fit right in if you want the salad to eat more like a picnic classic. Fold them in at the very end so they stay in pieces, and expect a softer, richer bowl that’s less crisp and more filling.
Storage and Reheating
- Refrigerator: Keep covered for up to 4 days. The potatoes soften a little as they sit, but the flavor gets better by day two.
- Freezer: I don’t recommend freezing this salad. The yogurt-based dressing can separate and the potatoes turn grainy after thawing.
- Reheating: Serve it cold or let it sit at room temperature for 15 to 20 minutes. Don’t microwave it; the dressing can break and the potatoes lose the texture that makes the salad work.

- Bring a pot of salted water to a boil and cook cubed red potatoes at 100°C (212°F) until tender, 10-15 minutes. You should be able to pierce a cube easily with a fork.
- Drain the potatoes and spread them out to cool for 5-10 minutes. The surface should look dry and no longer steaming.
- In a bowl, whisk plain Greek yogurt, mayonnaise, Dijon mustard, and white wine vinegar until smooth. Mix until no streaks of mayo remain and the dressing looks glossy.
- Season the dressing with salt and pepper to taste. Add a pinch at a time, tasting as you go, until it’s balanced.
- Add the cooled potatoes, fresh dill, green onions, and celery to a large bowl and toss to combine. Coat all potato pieces so the herbs and vegetables are evenly distributed.
- Pour the dressing over the potato mixture and toss well until every bite looks lightly coated. The dressing should cling rather than pool at the bottom.
- Refrigerate the potato salad for 2 hours before serving. Chill until it feels firm and cold, and the flavors taste more settled.
