2 pounds whole russet or Yukon gold potatoes

Kosher salt

1 stick softened butter or 1/2 cup extra-virgin olive oil

1 cup milk

Freshly ground pepper

2 tablespoons prepared horseradish

1/2 cup to 3/4 cup chopped scallions


  1. Put the potatoes in a saucepan; cover with cold water and add 2 tablespoons kosher salt. Bring to a simmer over medium-low to medium heat and cook, uncovered, until tender, about 45 minutes. Drain the potatoes and let sit until just cool enough to handle, then peel and transfer to a bowl.
  2. Add the butter to the potatoes. Add the milk, 2 teaspoons kosher salt, and pepper to taste; mash with a potato masher or fork.
  3. Fold in the horseradish. Spoon the mashed potatoes into a serving dish and sprinkle with the scallions.
