Ideal for vegan holiday gatherings, these mashed potatoes are rich, savory, and irresistibly delicious, making them a must-have vegan side dish for festive occasions.


Ingredients

Scale
  • 4 large russet potatoes, peeled and chopped
  • 2 large yellow onions, thinly sliced
  • 3 tablespoons olive oil or vegan butter
  • 1 cup almond milk or any plant-based milk
  • 2 tablespoons nutritional yeast (for a cheesy flavor)
  • Salt and black pepper to taste
  • Fresh thyme or rosemary (optional, for extra flavor)
  • Vegan sour cream or cashew cream (for garnish)

Instructions

  1. Start by peeling and chopping the potatoes into evenly sized pieces. Place them in a large pot filled with cold water and bring to a boil. Cook for about 15-20 minutes or until the potatoes are tender when pierced with a fork. Drain and set aside.
  2. While the potatoes are boiling, heat 2 tablespoons of olive oil or vegan butter in a large skillet over medium heat. Add the sliced onions and cook slowly, stirring occasionally. After about 20-25 minutes, the onions will turn golden-brown and develop a sweet, caramelized flavor. Season with a pinch of salt and optional thyme or rosemary.
  3. Once the potatoes are cooked and drained, transfer them to a large bowl. Mash using a potato masher or a hand mixer, gradually adding the plant-based milk to reach your desired creaminess. Mix in nutritional yeast and season with salt and black pepper.
  4. Fold the caramelized onions into the mashed potatoes, ensuring they are evenly distributed. Serve hot, garnished with vegan sour cream or cashew cream for an extra creamy touch. Optional fresh herbs or vegan cheese can also be added for enhanced flavor.

Notes

  • Use starchy potatoes like russet or Yukon Gold for the creamiest mash.
  • Cook the onions slowly over medium-low heat to develop their deep caramel flavor—patience is key!
  • Adjust the amount of plant-based milk to achieve your preferred creamy texture.
  • For extra richness, consider adding a splash of vegan gravy or mushroom broth during mashing.
