Ingredients

  • 2 lb baby Yukon Gold potatoes
  • 1 cup kosher salt
  • ¾ cup sour cream
  • ¼ cup mayonnaise
  • 1 Tbsp onion powder
  • 2 tsp Dijon mustard
  • 1 tsp freshly ground black pepper
  • 1 clove garlic
  • 1 bunch chives
  • ¼ whole red onion
  • ½ cup sour cream and onion potato chips

Cooking Instructions

  1. 1.

    Place potatoes in a large pot and pour in 3 qt. water to cover. Add 1 cup salt and bring water to a boil over medium-high heat. (Yes, this is a lot of salt, but it's the right amount to ensure potatoes are seasoned through and through.) Reduce heat and simmer, adjusting heat as needed, until potatoes until fork-tender, 15-20 minutes. Scoop out 1/2 cup potato cooking liquid and set aside. Drain potatoes in a colander and let sit until cool enough to handle, about 10 minutes.

    Meanwhile, combine sour cream, mayonnaise, onion powder, mustard, and pepper in a large bowl and mix well to combine. Add garlic and half of chives and mix just to incorporate.

    Place red onion in a fine-mesh sieve and rinse for several seconds to take away some of its raw bite. Pat dry with paper towels. Mix half of onion into dressing; set aside remaining onion for serving.

  4. 4.

    Working one at a time, set potatoes on a flat surface and crush slightly with the palm of your hand. Add to bowl with dressing along with 1/4 cup potato cooking liquid. Do this while the potatoes are still warm so that they can absorb all of the seasoning. Don't worry if the dressing looks a little loose and watery at the beginning-it will all get absorbed and become creamier as it sits. Taste and season with more salt or, if your dressing looks too thick, a splash of potato cooking liquid.
