Make velvety, fluffy mashed potatoes that taste like steakhouse favorites. This easy recipe uses Yukon Gold potatoes and simple additions for rich, comforting flavor perfect for any dinner.

Ingredients

Scale
  • 3 lbs Yukon Gold potatoes, peeled and quartered
  • 1 cup whole milk, warmed
  • 8 tablespoons unsalted butter, cut into pieces
  • 2 cloves garlic, minced
  • 1 teaspoon salt, plus more for boiling water
  • 1/2 teaspoon black pepper
  • 1/4 cup sour cream or heavy cream

Instructions

  1. Place the peeled and quartered potatoes in a large pot. Cover them with cold water by about one inch. Add 1 tablespoon of salt to the water.
  2. Bring the water to a boil over high heat. Reduce the heat to maintain a steady simmer and cook until the potatoes are fork-tender, about 15 to 20 minutes.
  3. While the potatoes cook, gently warm the milk and butter together in a small saucepan over low heat until the butter is melted. Do not boil. Add the minced garlic to the warm milk mixture and let it infuse for 5 minutes, then remove from heat.
  4. Drain the potatoes thoroughly in a colander. Return the hot, drained potatoes to the empty pot. Let them sit for 2 minutes to allow excess steam to evaporate; this helps prevent watery potatoes.
  5. Mash the potatoes using a potato masher or ricer until mostly smooth. Work quickly to keep the potatoes hot.
  6. Gradually pour the warm milk and butter mixture into the potatoes while continuing to mash or gently stir until you reach your desired creamy consistency. Avoid overmixing, which can make them gluey.
  7. Stir in the sour cream (or heavy cream), salt, and pepper. Taste and adjust seasoning as needed.
  8. Serve your restaurant-style mashed potatoes immediately as a perfect holiday side dish or weeknight comfort food.

Notes

  • For the smoothest texture, use a potato ricer instead of a standard masher.
  • Yukon Gold potatoes provide a naturally buttery flavor and creamy texture ideal for this recipe.
  • If you prefer a stronger garlic flavor, roast the garlic cloves before adding them to the warm milk.
