This sour cream and red potato salad uses mini red potatoes, tossed in a creamy sour cream, mayonnaise and mustard dressing, together with lots of diced green onion.

This red potato salad is another Summer essential salad here. I love the simplicity of it and the tang of the sour cream in the dressing.

This salad can be made well ahead. The red potatoes hold up really well and keep their lovely texture, while the generous sauce keeps them moist. And speaking of the generous sauce, I know it looks like a lot, but trust me, because of the large pieces of potato, it’s really just right. A perfect balance of potato and sauce.

Ingredients and Substitutions

Potatoes – while this is a red potato salad, it can certainly be made with mini yellow potatoes, as well :)

Sour Cream – you can use full fat or reduced fat sour cream for this salad.

White or White Wine Vinegar – use whichever you have or prefer.

Mayonnaise – use your favourite mayonnaise. You could also use salad dressing, such as Miracle Whip™ if you prefer it.

Green Onion – If you have chives on hand or in the garden, feel free to substitute chives for the green onion.

Recipe Tips

  • When buying your mini red potatoes, it’s best to select potatoes of similar size, so they cook at the same rate and are nicer in the salad. If your only choice is larger mini red potatoes, you may want to quarter them rather than halve them.
  • Be sure to watch your potatoes closely as they near done and cook only until tender.
  • If you happen to have a bit of bacon around, a bit of finely diced cooked bacon would be a nice addition to change this up.

Yield: 4 servings


  • 1 1/2 lb mini red potatoes
  • 1/2 Tablespoons white or white wine vinegar


  • 1/2 cup sour cream
  • 1/2 cup mayonnaise
  • 2 teaspoons Dijon mustard
  • 2 teaspoons lemon juice or white vinegar
