2 pounds whole russet or Yukon gold potatoes
1 stick softened butter or 1/2 cup extra-virgin olive oil
1 cup buttermilk
Freshly ground pepper
2 tablespoons chopped fresh parsley
2 tablespoons chopped fresh dill
2 tablespoons chopped fresh chives
1 cup shredded cheddar cheese
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.
Add the butter to the potatoes. Add the buttermilk, 2 teaspoons kosher salt, and pepper to taste; mashwith a potato masher or fork.
Stir the parsley, dill and chives into the potatoes. Fold in the cheddar. Spoon the mashed potatoes into a serving dish.
