Instructions

  1. Prepare Butter

    Cut the butter into eight pieces and let it sit at room temperature to soften while you work on the potatoes.
  2. Prep Potatoes

    Peel (if desired) and cut the potatoes into 1½‑inch pieces. Rinse them in a colander under cold water for about one minute.
  3. Boil Potatoes

    Place the potatoes in a large pot, cover with cool water at least ½ inch above the pieces (pot no more than two‑thirds full). Generously salt the water, bring to a boil over high heat, and cook until fork‑tender, roughly 10 minutes.
  4. Warm Milk

    While the potatoes boil, heat the milk until warm, either in the microwave or in a small saucepan over medium‑low heat.
  5. Drain and Dry

    Drain the potatoes well, return them to the pot, and let sit for about two minutes, stirring occasionally to steam off excess moisture.
  6. Mash

    Mash the potatoes using a masher or, preferably, a potato ricer for a smooth texture.
  7. Incorporate Butter

    Add the softened butter pieces to the mashed potatoes and stir until fully melted and incorporated.
  8. Add Milk and Seasonings

    Drizzle the warmed milk over the potatoes, then add the salt and pepper, stirring until combined.
  9. Optional Add‑ins

    If desired, stir in sour cream, pressed garlic, and/or parmesan cheese until evenly mixed.
  10. Serve

    Serve the mashed potatoes warm.

Tips

For the smoothest potatoes, use a ricer and avoid over‑mixing, which can make them gluey. Adjust seasoning after adding optional ingredients. Reheat leftovers with a splash of milk to restore creaminess.

About this recipe

The mashed potatoes are boiled until tender, then mashed and enriched with softened butter and warm whole milk for a silky finish. Using a ricer or masher ensures a smooth consistency without becoming gluey. Optional additions like sour cream or cheese add richness and depth, making the dish versatile for any meal.

Serve the potatoes hot as a side to roasted meats, gravies, or holiday feasts. They keep well refrigerated for up to five days and can be frozen for longer storage, reheating with a splash of milk to restore creaminess.
