Ingredients
  

  • 5 pounds potatoes (Yukon Gold or Russet), peeled and cubed
  • 1 cup sour cream
  • ½ cup butter (1 stick), melted
  • ½ cup milk or cream, warmed
  • Salt and pepper to taste
  • 2 cloves garlic, minced (optional)
  • Chopped chives or parsley for garnish

Instructions
 

  • Boil Potatoes: Place potatoes in a large pot, cover with salted water, and bring to a boil. Cook until tender, about 15–20 minutes.
  • Drain & Mash: Drain well, then mash until smooth using a potato masher or hand mixer
  • Mix Ingredients: Add sour cream, melted butter, and warm milk. Mix until creamy and well combined. Season with salt and pepper.
  • Store: Transfer to a greased baking dish. Let cool, then cover and refrigerate for up to 2 days.
  • Reheat: To serve, remove from the fridge 30 minutes before baking. Cover with foil and bake at 350°F (175°C) for 30–40 minutes until heated through.
  • Serve: Garnish with butter pats and chopped chives before serving.

Notes

  • Use Yukon Gold potatoes for a buttery texture.
  • Warm the milk before adding for smoother blending.
  • Do not overmix — it can make potatoes gummy.
  • Add roasted garlic for a deeper flavour.
  • Store leftovers in an airtight container for up to 3 days.
