A sour cream dressing turns a basic potato salad recipe into something special for your next summer cookout. This salad can be made with russet, red, or Yukon gold potatoes. A waxier potato such as the red potato will hold its shape better after being cooked. You may also enjoy using more than one kind of potato in the dish, perhaps even red, white, and blue baby potatoes.

Sour cream replaces some of the mayonnaise, resulting in a very creamy and slightly tangy potato salad. Serve it at your next cookout as a delicious side dish for grilled meat.

  • 4 pounds potatoes

  • 1 teaspoon kosher salt, plus more for the potato water

  • 1/2 tablespoon Dijon mustard

Tips

  • This potato salad doesn't contain eggs, so it is less risky (when made with commercial mayonnaise) to take to a potluck or picnic where it may be at room temperature for an hour or more. However, it should be kept refrigerated before you place it on the table. Leftovers should be promptly refrigerated and eaten within a day or two.
  • By boiling your potatoes in salted water, you will be pre-seasoning them and you can use less added salt.
  • Leave the skins on the potatoes if you prefer a more rustic potato salad. This also saves you time and the inevitable nicks from the knife or peeler. However, scrub the potatoes well before cooking. Remove any eyes from the potatoes as those contain chemicals that are undesirable.
  • An easy method for cooking the potatoes is to cube your potatoes and cook them in a microwave-safe steamer in the microwave. You won't need to add any extra water and it is easy to test them for doneness. Potatoes will be less likely to crumble or be soggy when cooked in the microwave rather than boiled.
  • Make sure your potatoes are cool before mixing. If they're warm, you can end up with a watery potato salad.

Recipe Variations

  • Substitute Greek yogurt for the sour cream or the mayonnaise for a lighter option.
  • The recipe will work with reduced-fat or fat-free sour cream if you prefer.
  • Add herbs to the potato salad such as fresh or dried dill or chopped fresh parsley.
  • A tablespoon or more of dill relish, sweet pickle relish, or chopped pickled peppers can add more flavor.
