Make ultra-creamy mashed potatoes baked until golden brown. This recipe delivers rich, velvety potatoes perfect for holiday dinners or family comfort food.

Ingredients

Scale
  • 3 lbs Russet potatoes, peeled and quartered
  • 1 cup whole milk, warmed
  • 8 tablespoons unsalted butter, cut into pieces
  • 8 ounces cream cheese, softened
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 cup shredded sharp cheddar cheese (for topping)
  • 4 slices bacon, cooked and crumbled (optional)
  • 2 tablespoons chopped fresh chives (for garnish)

Instructions

  1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
  2. Place the peeled and quartered potatoes in a large pot and cover with cold, salted water. Bring to a boil and cook until the potatoes are fork-tender, about 15 to 20 minutes.
  3. Drain the potatoes completely. Return them to the hot, empty pot over low heat for one minute to dry out any excess moisture. Remove from heat.
  4. Add the warm milk, butter pieces, and cream cheese to the potatoes. Mash thoroughly until the mixture is smooth and creamy. Use a hand mixer for the creamiest texture if desired.
  5. Stir in the salt and pepper until combined. Taste and adjust seasoning if needed.
  6. Spread the mashed potato mixture evenly into the prepared baking dish.
  7. Sprinkle the shredded cheddar cheese evenly over the top of the potatoes. If using, scatter the crumbled bacon over the cheese.
  8. Bake for 20 to 25 minutes, or until the potatoes are heated through and the cheese topping is melted and golden brown.
  9. Remove from the oven. Let the dish rest for 5 minutes before serving. Garnish with fresh chives.

Notes

  • For an ultra-creamy result, do not overmix the potatoes once the liquid is added, as this can make them gluey.
  • You can prepare the mashed potatoes and assemble the casserole up to 24 hours ahead. Cover and refrigerate. Add 10-15 minutes to the baking time if baking directly from the refrigerator.
  • This recipe works well as a make ahead potato casserole for potlucks.
