Servings 10

Ingredients

  • 5 pounds russet potatoes or Yukon gold potatoes - peeled and cut into 1 inch pieces
  • 1 (8 ounce) package cream cheese cubed and at room temperature
  • 1 ¼ cups sour cream
  • ¾ teaspoon onion powder
  • ¾ teaspoon garlic powder
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • 2 to 3 tablespoons butter, melted and additional butter for greasing baking dish
  • 1 tablespoon chopped fresh chives or parsley optional garnish

Instructions

  • Grease a 13 x 9 baking dish with butter. Set aside.
  • Place potatoes in a 6 quart Dutch oven or large pot and cover with cold water. Bring to a gentle boil and cook (uncovered) until fork-tender (but not falling apart), about 13 to 16 minutes.
  • Drain potatoes in a colander and return to pot. Mash potatoes (using a potato masher) with cubed cream cheese until combined.
  • Add sour cream, onion powder, garlic powder, salt and pepper. Mash until combined. Season with additional salt, pepper, garlic powder and/or onion powder, if desired and mash (or stir) again to combine.
  • Transfer to prepared baking dish and spread evenly.
  • Allow potatoes to cool to room temperature. Cover tightly with foil and refrigerate overnight (or up to 2 days).
  • When ready to bake, remove from refrigerator 30 minutes prior to baking.
  • Preheat your oven to 350 degrees F. Bake (covered with foil) for 50 minutes.
  • Carefully remove foil and bake an additional 5 to 10 minutes, or until heated through.
  • Top as evenly as possible with melted butter and chopped fresh chives (or parsley) when serving.

Notes

  • After baking, leftovers can be stored in the fridge for up to 3 days (allow to cool to room temperature and store in an airtight container).
  • If you prefer your potatoes smoother and fluffier, feel free to use a hand mixer to beat at high speed until your desired consistency is reached.
