Ingredients
  

For the Mashed Potatoes
  • 4 lb Yukon Gold potatoes peeled and cut into even chunks
  • 8 oz cream cheese softened
  • 1/2 cup unsalted butter softened
  • 3/4 cup sour cream
  • 1/2 cup whole milk warmed
  • 1 1/2 tsp kosher salt or to taste
  • 1/2 tsp freshly ground black pepper
  • 1/2 tsp garlic powder optional
For the Topping
  • 2 tbsp unsalted butter cut into small pieces
  • 2 tbsp chopped fresh chives or parsley optional garnish

Equipment

  • 1 Large pot
  • 1 Colander
  • 1 Potato masher or potato ricer
  • 1 Large mixing bowl
  • 1 9×13-inch baking dish
  • 1 Rubber spatula
  • 1 Aluminum foil
  • 1 Measuring cups and spoons

Method
 

  1. Peel the Yukon Gold potatoes and cut them into evenly sized chunks, approximately 1 1/2 inches.
  2. Place the potatoes in a large pot and cover with cold water by about 1 inch. Add a generous pinch of salt.
  3. Bring the water to a boil over medium-high heat. Reduce to a gentle boil and cook for 15–20 minutes, or until the potatoes are very tender when pierced with a fork.
  4. Drain the potatoes thoroughly in a colander. Return them to the warm pot for 1–2 minutes over low heat, stirring gently to allow excess moisture to evaporate.
  5. Mash the potatoes with a potato masher or pass them through a potato ricer until smooth.
  6. Add the softened cream cheese, 1/2 cup butter, sour cream, and warmed milk. Stir gently until the mixture is creamy and evenly combined.
  7. Season with kosher salt, black pepper, and garlic powder if using. Taste and adjust the seasoning.
  8. Lightly grease a 9x13-inch baking dish. Spread the mashed potatoes evenly in the dish.
  9. Dot the surface with the remaining 2 tablespoons of butter.
  10. If preparing ahead, allow the dish to cool briefly, then cover and refrigerate promptly within 2 hours of cooking. Store for up to 2 days.
  11. When ready to serve, preheat the oven to 350°F (175°C). Remove the dish from the refrigerator while the oven preheats, but do not leave it at room temperature for an extended period.
  12. Cover the baking dish with aluminum foil and bake for approximately 25–35 minutes, or longer if needed, until the center reaches 165°F (74°C).
  13. Stir gently if necessary. If the potatoes seem too thick, add a small splash of warm milk.
  14. Garnish with chopped fresh chives or parsley and serve hot.

Notes

Recipe Tips
  • Use Yukon Gold potatoes for a naturally creamy, buttery texture.
  • Cut the potatoes into evenly sized pieces for consistent cooking.
  • Drain the potatoes thoroughly to prevent watery mashed potatoes.
  • Warm the milk before adding it to the potatoes.
  • Use softened cream cheese and butter for easier mixing.
  • Avoid using a blender or food processor, which can make mashed potatoes gummy.
  • Add a splash of warm milk if the potatoes become too thick during reheating.
Make Ahead: Prepare the mashed potatoes up to 2 days in advance. Transfer them to a covered baking dish and refrigerate promptly.
Storage: Refrigerate leftovers in airtight containers for 3–4 days.
Freezing: Freeze cooled mashed potatoes for up to 2 months for best quality. Thaw in the refrigerator before reheating.
Reheating: Cover and bake at 350°F (175°C) until the center reaches 165°F (74°C).
Serving Suggestions: Serve with roast turkey, meatloaf, chicken, beef, or other holiday main dishes.
