Ingredients

  • 2 pounds Yukon gold potatoes, diced (about 5 cups) leave the skins on for added texture and nutrients

  • ½ cup low-fat buttermilk

  • ½ cup skim milk

  • 4 tablespoons grated Parmesan cheese

  • Salt, to taste

  • 1 tablespoon unsalted butter (for finishing)

Instructions

  1. Cook the potatoes:
    Place diced potatoes in a large saucepan and cover with cold water. Bring to a boil, then reduce heat and simmer for about 10 minutes, or until potatoes are fork-tender.

  2. Warm the milk mixture:
    While the potatoes are cooking, combine buttermilk and skim milk in a small saucepan. Warm gently over very low heat do not boil, as this may cause curdling.

  3. Mash and mix:
    Drain the cooked potatoes thoroughly, then return them to the pot. Pour in the warmed milk mixture and mash to your desired consistency smooth, chunky, or somewhere in between.

  4. Add flavor:
    Stir in the grated Parmesan and salt to taste. Mix until well combined.

  5. Finish with butter:
    Transfer to a serving bowl and top with the unsalted butter, letting it melt over the warm mash.

Nutrition Boost

Yukon gold potatoes are naturally creamy and a good source of vitamin C and potassium. Leaving the skins on adds fiber, while buttermilk provides a tangy flavor and a little protein without the richness of cream. Parmesan contributes calcium and umami while keeping things flavorful with less added fat.

Serving Tip: Garnish with chopped chives or a sprinkle of extra Parmesan for an elevated presentation.
