Red potato salad lands best when it’s creamy but still tastes like potatoes, not just dressing. This lighter version keeps that balance. The red skins hold their shape after boiling, the Greek yogurt gives the dressing a clean tang, and the small amount of mayonnaise rounds everything out without turning the bowl heavy.

The trick is in the texture of the potatoes and the way the dressing is mixed. You want the cubes tender all the way through, but not falling apart, because the chilled salad gets better after a long rest and the potatoes will keep absorbing flavor. The vinegar and Dijon sharpen the dressing so the yogurt doesn’t taste flat, and the dill, celery, and green onions give the whole dish a fresh, crisp finish.

Below you’ll find the details that matter most: how to keep the potatoes from turning mushy, why this dressing holds up after chilling, and a few easy ways to adjust the salad for different diets and make-ahead plans.

The Reason This Salad Stays Creamy Without Getting Heavy

The main thing that goes wrong in lighter potato salad is that people cut the mayo too far and forget that potatoes need enough coating to taste finished. Greek yogurt brings tang and body, but on its own it can read sharp and a little lean. The small amount of mayonnaise fills in the gaps and gives the dressing that soft, familiar richness people expect from potato salad.

Another place this salad succeeds is the chill time. Warm potatoes drink up dressing fast, and if you serve it right away the flavors stay on the surface. A two-hour rest lets the dressing settle into the potatoes and thickens everything up without making the celery and onions lose their crunch.

What Each Ingredient Is Doing in the Bowl

• Red potatoes — These are the right potato for this style because they hold their shape after boiling and have a waxy texture that stays pleasant after chilling. If you swap in russets, the salad turns softer and more prone to breaking down.
• Greek yogurt — This gives the salad its lighter body and tang. Full-fat or low-fat both work; nonfat can taste a little thin, so I usually stay with plain yogurt that still has some creaminess.
• Mayonnaise — You only need a little to smooth out the dressing and make it taste rounded instead of sharp. Don’t skip it unless you’re changing the whole style of the salad.
• Dijon mustard and white wine vinegar — These are the wake-up call in the dressing. Dijon adds depth and helps the yogurt taste savory, while vinegar keeps the salad from feeling flat once it’s cold.
• Dill, green onions, and celery — These bring freshness and crunch. Dill is strongest when it’s fresh, but if you’re in a pinch, use a smaller amount of dried dill and let it sit in the dressing a few minutes before tossing.

How to Keep the Potatoes Intact From Pot to Fridge

Boil Until Just Tender

Start the potatoes in salted water and cook them until a knife slides in with a little resistance, not until they’re loose or crumbly. If they go too far, they’ll fall apart when you toss them with the dressing. Drain them well and let the steam escape for a few minutes so the salad doesn’t get watery.

Build the Dressing Before the Potatoes Cool Completely

Mix the Greek yogurt, mayonnaise, Dijon, vinegar, salt, and pepper while the potatoes are draining. The slight warmth from the potatoes helps the dressing spread more evenly once everything comes together. If the potatoes are icy cold before mixing, the dressing tends to sit in streaks instead of coating each piece.

Toss Gently, Then Chill

Add the dill, green onions, and celery with the potatoes, then pour the dressing over the top and fold everything together with a light hand. Stirring hard breaks the potatoes and turns the salad pasty. Once it’s coated, cover it and refrigerate it for two hours so the flavors settle and the dressing thickens up around the potatoes.

Ingredients

  

Red potato salad components

• 3 lb red potatoes
• 0.5 cup plain Greek yogurt
• 0.25 cup mayonnaise
• 2 tbsp Dijon mustard
• 2 tbsp white wine vinegar
• 0.25 cup fresh dill, chopped
• 0.25 cup green onions, sliced
• 0.5 cup celery, diced
• 1 salt and pepper to taste

Equipment

• 1 Dutch oven

Method

 

Boil and cool the potatoes

1. Bring a large pot of water to a boil, add the red potatoes, and boil until tender, 10-15 minutes with visible bubbling. Drain the potatoes and cool until no longer hot, about 10 minutes.

Make the Greek yogurt dressing

1. In a mixing bowl, whisk together plain Greek yogurt, mayonnaise, Dijon mustard, and white wine vinegar until smooth, 1-2 minutes. Season with salt and pepper to taste and whisk again until fully combined.

Combine and chill

1. Add the cooled red potatoes to the dressing, then stir in fresh dill, green onions, and celery so everything is evenly coated, about 2-3 minutes.
2. Pour the dressed potato mixture into a serving bowl and toss well to distribute herbs and dressing, then spread into an even layer so it chills uniformly.
3. Refrigerate the potato salad for 2 hours before serving so the flavors meld, keeping it at 40°F or below.

Notes

Pro tip: cool the boiled potatoes well before mixing so the dressing stays thick and clings instead of turning runny. Store covered in the refrigerator up to 4 days; freeze not recommended for best texture. For a lighter swap, use reduced-fat mayonnaise or all-Greek-yogurt dressing (swap the mayo amount) while keeping the Dijon and vinegar for tang.
