Ingredients

  • 1 teaspoon olive oil
  • 2 medium yellow onions chopped
  • 2 ½ pound russet potatoes peeled and cut into ½-inch cubes
  • 1 ¼ pound cauliflower cut into ½-inch pieces
  • 1 ½ teaspoons kosher salt divided
  • 4 ounces light cream cheese (or vegan cream cheese)
  • cup low-fat (1%) milk or a plant-based milk (such as soy or almond)
  • 1 roasted red pepper chopped
  • ½ teaspoon salt
  • ½ teaspoon freshly ground black pepper

Instructions

  • Heat the olive in a large skillet over medium heat.
  • Add the onions and cook, stirring occasionally, until the onions are golden brown.

The Potatoes:

  • Place cubed potatoes and cauliflower in a large saucepan and cover the vegetables with cold water.
  • Bring to a boil and cook until potatoes and cauliflower are tender when pierced with a fork, about 15 minutes.
  • Drain the vegetables, return to saucepan and set over medium heat, stirring the potatoes and cauliflower until dry, 1 to 2 minutes. Remove from the heat and cover to keep warm over low heat.
  • Using a food mill, potato ricer or potato masher, mash the potatoes with the milk (or plant-based milk) to remove the large lumps.
  • Add the cream cheese to the potatoes and continue to mash until the potatoes are smooth and the cream cheese is incorporated.
  • Stir the caramelized onions and roasted peppers into the mashed potatoes. Season with salt and pepper. Serve.
