In this healthy mashed potato recipe, we flavor the mashed potatoes with nutty browned butter and tangy buttermilk. For a pretty presentation, serve garnished with thinly sliced fresh chives.
Peel potatoes, if desired, and cut into 2-inch chunks. Place the potatoes and salt in a large heavy saucepan. Add water to cover by 2 inches. Bring to a boil. Reduce heat to simmer, cover, and cook until potatoes are very tender, 10 to 15 minutes. Drain well.
Transfer the potatoes to a large bowl. Mash with a potato masher, an electric hand-held mixer or by working through a ricer.
Melt butter in a small saucepan over medium heart. Continue heating until it starts bubbling; stir and cook, watching carefully so it doesn't burn, until it turns golden brown, 2 to 4 minutes. Stir the browned butter, buttermilk and pepper into the mashed potatoes.
Make Ahead Tip: Transfer to a slow cooker, cover and keep on the “warm” setting for up to 2 hours.
