Potatoes and leeks are a classic flavor pairing, and here, they come together in luscious, creamy mashed potatoes. Serve with roast chicken, meatloaf, or as a bed for seared or roasted fish. This recipe doubles or triples easily, but add the milk in increments, as you may not need it all.

  • 1-1/2 lb. Yukon Gold potatoes, peeled and cut into 1-inch pieces
  • Kosher salt
  • 2 Tbs. unsalted butter
  • 2 medium leeks (white and light-green parts only), halved lengthwise, washed, and sliced crosswise into 1/4-inch-wide pieces (about 1 cup)
  • 1/2 cup sour cream, at room temperature
  • 1/2 cup whole milk, heated; more as needed
  • Freshly ground white or black pepper
     

Put the potatoes in a large saucepan and cover with cold water by at least 1 inch. Bring to a boil over high heat, add a generous 1/2 tsp. salt, and lower the heat to a steady simmer. Cover the pot partially and cook until the potatoes are just tender when pierced with a fork, 10 to 12 minutes.

Meanwhile, melt the butter in a 10-inch skillet over medium heat. Add the leeks and sauté, stirring often, until tender but not browned, about 6 minutes.

Drain the potatoes and return to the pan. Steam-dry over low heat, shaking the pan until the potatoes leave a light film on the bottom, about 3 minutes.

Mash the potatoes with a potato masher. Stir in the leeks, sour cream, and milk, adding more milk as needed to reach your desired consistency. Season to taste with salt and pepper. Serve.
 

Variations

Steam-drying the potatoes after they’re cooked allows excess moisture to evaporate, so they’re more intensely flavored and have a denser, more luxurious texture.

Absolutely delicious. Use a potato ricer instead of mashing. Don't be afraid to use extra sour cream to make the potatoes a bit more tangy.

These were fantastic! I did not add any extra milk to them because we both like ours thick. They were flavorful, smooth and yummy with some texture from the leeks. The best I have ever eaten. It was the first time I have used Yukon Golds and I am sold on them for mashed from now on. Update 09/18/13: One tip on these, they taste much better if the leeks are caramelized somewhat. Just softening the leeks does not give them the same depth of flavor as the caramelized. Yummmmm!

This recipe was okay. It's just mashed potatoes, so it's not too exciting, but they tasted very good. I liked the tip about steaming the potatoes.

i made this recipe, adding a few more vegetables...carrots and celeriac. It was delicious!!!

We enjoyed this dish very much. It would be an excellent side dish for Thanksgiving.

Easy to make and excellent: soft, creamy, elegant. In French I would say: "voluptueux"
