Mix 2 tablespoons olive oil, 2 teaspoons kosher salt and 1 teaspoon pepper. Pierce 6 russet potatoes with a fork; rub with the oil. Bake on the top oven rack at 375 degrees F (put a baking sheet below to catch drippings) until tender, 50 minutes. Slice open and top with butter, salt, pepper and chives.
