Make the ultimate comfort food side dish with these creamy baked mashed potatoes. This recipe combines rich mashed potatoes with three cheeses, baked until golden brown for a satisfying texture.

Ingredients

Scale
  • 3 lbs Russet potatoes, peeled and quartered
  • 1 cup whole milk
  • 8 tablespoons unsalted butter
  • 8 ounces cream cheese, softened
  • 1 cup shredded sharp cheddar cheese
  • 1/2 cup shredded Gruyère cheese
  • 1/2 cup grated Parmesan cheese
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 cup sour cream
  • 1 large egg
  • 1/2 cup panko breadcrumbs (for topping)

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. 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 well and return them to the hot pot to dry out for one minute over low heat, shaking occasionally.
  4. Remove the pot from the heat. Add the milk and butter. Mash the potatoes until smooth.
  5. Beat in the softened cream cheese until fully incorporated and the mixture is velvety.
  6. Stir in the cheddar cheese, Gruyère cheese, Parmesan cheese, salt, pepper, sour cream, and egg until just combined. Do not overmix.
  7. Spread the mashed potato mixture evenly into the prepared baking dish.
  8. In a small bowl, toss the panko breadcrumbs with one tablespoon of melted butter. Sprinkle the breadcrumbs evenly over the top of the potatoes.
  9. Bake for 25 to 30 minutes, or until the potatoes are heated through and the topping is golden brown and slightly crisp.
  10. Let the dish rest for 5 minutes before serving.

Notes

  • For an extra rich flavor, use heavy cream instead of milk.
  • You can prepare the mashed potato base a day ahead and store it covered in the refrigerator. Add the topping before baking.
  • This recipe works well as a make ahead potato casserole for holiday dinners.
