Creamy Leek Mashed Potatoes
Evan Sung / For The Times

Silky and soft, these are the ultimate comforting mashed potatoes. Caramelized leeks and nutritional yeast give these vegan spuds even more richness and complexity than butter and cream. Use a golden-colored (not brown) vegetable broth to keep the potatoes a ... Read more

45 minutes. Makes about 8 cups.
  • 4 ½ pounds Russet potatoes (about 5 large), peeled and cut into 2-inch chunks
  • Kosher salt and freshly ground black pepper
  • ¼ cup grapeseed or other neutral oil
  • ¼ cup everyday extra-virgin olive oil, plus more
  • 3 medium leeks, white and pale green parts only, cut into ¼-inch half-moons
  • 3 tablespoons nutritional yeast
  • 1 cup vegetable broth
  • Snipped chives, for garnish

Step 1Put the potatoes in a large saucepot and add enough cold water to cover by 2 inches. Add 3 tablespoons salt. Cover and bring to a boil over high heat. Reduce the heat to keep the potatoes boiling without causing the water to spill out. Continue cooking until the potatoes are very tender, about 15 minutes. A knife should slide through very easily and cause the potato to split.

Step 2While the potatoes boil, combine both oils, the leeks and a generous pinch of salt in a large saucepan. Set over medium heat and cook, stirring occasionally, until the leeks are very tender, about 15 minutes. Add the nutritional yeast and cook, stirring for 1 minute, then add the broth. Bring to a boil, then simmer for 10 minutes.

Step 3Drain the potatoes and let stand in the colander until very dry, about 5 minutes. Pass the potatoes through a food mill or ricer back into the pot in which they cooked.

Step 4Transfer the leek mixture to a blender and puree on high speed until very smooth. Add 2 cups of the leek mixture to the potatoes and fold gently until evenly distributed. Season to taste with salt and pepper. For creamier potatoes, fold in more of the leek mixture. Transfer to a serving dish, drizzle with more olive oil and garnish with chives.

The potatoes can be refrigerated in an airtight container for up to 3 days. Reheat in a large saucepan over low heat with a little extra broth or leek mixture.
