Red potato salad with a lighter dressing keeps the creamy comfort people want, but it lands fresher on the plate and never feels heavy. The red potatoes hold their shape instead of collapsing into mash, and the mix of Greek yogurt, a little mayonnaise, Dijon, and vinegar gives the dressing enough body to coat every piece without turning greasy.

The trick is treating the potatoes gently from the start. Boil them just until tender, then cool them before adding the dressing so they keep their edges and don’t soak up too much liquid. The yogurt brings tang and thickness, while the mustard sharpens the flavor and helps the dressing taste full even with less mayo.

Below, I’ve added the small details that make this version work reliably: how to keep the potatoes from getting watery, which ingredient really carries the dressing, and how to adjust it if you want it even lighter or a little more classic.

The Reason This Potato Salad Stays Creamy Without Getting Heavy

Most light potato salads go wrong because they cut the mayo and forget to replace the body it was giving the dressing. Greek yogurt solves part of that problem, but only if you balance it with enough mustard and vinegar to keep the flavor awake. Here, the dressing tastes rich without feeling dense because the yogurt adds thickness, the mayo rounds it out, and the vinegar keeps the whole bowl from tasting flat.

The other thing that matters is temperature. Warm potatoes drink up dressing fast, which sounds helpful until they turn soft and muddy. Let them cool enough to handle before tossing, then chill the finished salad for at least two hours so the flavors settle and the dressing clings instead of sliding off.

What Each Ingredient Is Actually Doing in This Bowl

• Red potatoes — These are the backbone of the salad because they hold their shape after boiling and give you creamy centers with intact skins. Yukon golds work in a pinch, but russets break down too much and make the salad soft instead of chunky.
• Plain Greek yogurt — This is what makes the dressing feel lighter without losing creaminess. Use full-fat or 2% if you can; nonfat works, but the dressing tastes a little sharper and thinner.
• Mayonnaise — A smaller amount of mayo gives the dressing the familiar potato salad richness. Don’t skip it entirely unless you want a tangier, more yogurt-forward salad that tastes more like a creamy herb dressing than classic potato salad.
• Dijon mustard and white wine vinegar — These are the brighteners that keep the dressing from tasting flat. Dijon also helps the emulsion stay smooth, so the dressing coats the potatoes evenly instead of pooling at the bottom of the bowl.
• Fresh dill, green onions, and celery — Dill gives the salad its fresh, grassy note, while celery and green onions add crunch and bite. If you need to swap anything, parsley can stand in for dill, but the salad will lose some of that unmistakable herbal lift.

Building the Salad So the Potatoes Stay Intact

Boil Until Tender, Not Split

Cut the potatoes into even cubes so they cook at the same pace, then simmer them until a knife slips in with just a little resistance. If they start breaking at the edges, they’re already going too far. Overcooked potatoes turn the dressing cloudy and make the final salad look more mashed than tossed.

Cool Before You Dress

Drain the potatoes well and let the steam escape before mixing anything in. If they’re piping hot, they’ll absorb the dressing unevenly and can make the yogurt look loose. You want them warm enough to take on flavor, but cool enough to keep their shape.

Mix the Dressing Until Smooth

Stir the Greek yogurt, mayonnaise, mustard, vinegar, salt, and pepper until the mixture looks glossy and even. If you see streaks of yogurt or mustard, keep whisking before it goes anywhere near the potatoes. A smooth base coats better and gives you a cleaner finish in the bowl.

Fold, Then Chill

Add the dill, green onions, and celery to the potatoes, then pour over the dressing and toss gently. Don’t stir aggressively or the edges will start to break down. Once everything is coated, refrigerate it for two hours so the dressing thickens back up and the flavor settles into the potatoes.

Ingredients Equipment Method Notes

Ingredients

  

Red potatoes

• 3 lb red potatoes cubed

Greek yogurt dressing base

• 0.5 cup plain Greek yogurt
• 0.25 cup mayonnaise
• 2 tbsp Dijon mustard
• 2 tbsp white wine vinegar
• salt and pepper to taste

Vegetables and herbs

• 0.25 cup fresh dill, chopped
• 0.25 cup green onions, sliced
• 0.5 cup celery, diced

Equipment

• 1 Dutch oven

Method

 

Boil and cool the potatoes

1. Bring a large pot of water to a boil, then add the cubed red potatoes and cook at a steady boil for 15–20 minutes, until easily pierced with a fork (no hard centers). The cubes should look tender and just starting to soften at the edges.
2. Drain the potatoes in a colander and spread them out to cool for about 10 minutes, until warm rather than hot. You should see steam fade and the surface look matte, not wet.

Make the light dressing

1. In a mixing bowl, whisk together plain Greek yogurt, mayonnaise, Dijon mustard, and white wine vinegar, then season with salt and pepper to taste. The dressing should look smooth and thick enough to coat a spoon.

Assemble and chill

1. Add the cooled potatoes, fresh dill, green onions, and celery to a bowl and toss to distribute the herbs and vegetables evenly. The mixture should be evenly speckled with green.
2. Pour the dressing over the potato mixture and toss well until every piece is lightly coated. The salad should look glossy but not swimming in sauce.
3. Cover and refrigerate for 2 hours before serving. After chilling, the flavors should taste more blended and the dressing should cling to the potatoes.

Notes

For the best texture, cool the potatoes to warm (not piping hot) before dressing so the Greek yogurt mixture thickens instead of thinning. Refrigerate in an airtight container for up to 4 days; freeze is not recommended since potatoes and yogurt-based dressing can change texture. If you want a reduced-fat option, use light mayonnaise (or replace the mayonnaise entirely with additional Greek yogurt) for an even lighter dressing.
