Ingredients

• Ingredients
  1. 6 pounds Yukon Gold potatoes, peeled and halved
  2. 2 cups whole milk
  3. 1 1/2 sticks unsalted butter
  4. Kosher salt
  5. 1 cup crème fraîche
  6. 1/2 cup finely chopped chives
  7. Freshly ground pepper

Directions

1. In a large pot, cover the potatoes with cold water and bring to a boil. Cover and cook over moderate heat until the potatoes are tender, about 20 minutes; drain. Press the potatoes through a ricer into a large saucepan set over low heat.
2. Meanwhile, in a small saucepan, combine the milk with 10 tablespoons of the butter and 1 tablespoon of salt and cook over moderate heat until the butter is melted, about 3 minutes.
3. Pour the hot milk over the riced potatoes and cook over moderate heat, stirring occasionally, until blended, about 2 minutes. Stir in the crème fraîche, the remaining 2 tablespoons of butter and the chives and cook until the potatoes are heated through, about 5 minutes. Season with salt and pepper, transfer the mashed potatoes to a bowl and serve.

Make Ahead

The mashed potatoes can be kept covered at room temperature for up to 3 hours. Reheat before serving.
