In this healthy mashed potato recipe, we flavor the mashed potatoes with leeks lightly sautéed in butter and tangy buttermilk. These mashed potatoes are an amazing side to grilled steak or chicken.

Ingredients

  • 3 pounds Yukon Gold potatoes (about 12 medium)

  • 1 tablespoon salt

  • 2 tablespoons butter

  • 4 cups halved and thinly sliced leeks (about 2 large; see Tip), white and light green parts only

  • 1 cup buttermilk

  • Black or white pepper to taste

Directions

  1. Peel potatoes, if desired, and cut into 2-inch chunks. Place the potatoes and salt in a large heavy saucepan. Add cold 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.

  2. Meanwhile, melt butter in a large skillet over medium heat. Add leeks and cook, stirring, until soft and beginning to brown, 4 to 8 minutes.

  3. Transfer the potatoes to a large bowl. Mash with a potato masher, an electric hand-held mixer or by working through a ricer.

  4. Stir the leeks, buttermilk and pepper into the mashed potatoes.

Tips

Make Ahead Tip: Transfer to a slow cooker, cover and keep on the “warm” setting for up to 2 hours.

Tip: To clean leeks, trim off green tops and white roots and split lengthwise. Place in plenty of water and swish around to release any sand or soil. Drain. Repeat until no grit remains.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
