2 ½pounds (about 7)Yukon Gold potatoes (about 7 medium),scrubbed and cut in half
1tablespoonKosher salt for the water, plus 1 teaspoon for potatoes
¾ cup (1 ½ stick)unsalted butter, room temperature
1cupmilk or heavy cream, warmed
¼cup sour cream or Greek yogurt
½teaspoon black pepper
2tablespoonsminced chives(optional)
Instructions
Add potatoes and 1 tablespoon Kosher salt to a medium-sized saucepan, fill to cover with water by 2 inches. Place over medium-high heat. Allow to come to a boil and reduce to a rapid simmer. Simmer for 20-25 minutes, until the potatoes can easily be pierced with a fork.
Strain the potatoes and use a set of tongs to peel away the skin, if desired.
Add the potatoes back into the pot along with the butter and the additional 1 teaspoon of Kosher salt. Mash using a potato masher, ricer, or handheld mixer on low, until smooth to your liking.
Add the cream or milk a ¼ cup at a time, stirring gently until incorporated until you've reached your desired consistency. Note, it will thicken slightly as it sits. Stir in the sour cream, add the pepper and chives (if using), and stir. Add more salt and pepper to taste, if desired. Serve and enjoy.
