A recipe for rich, creamy mashed potatoes baked in the oven with cheese and bacon for a comforting side dish.

Ingredients

Scale
  • 3 lbs Russet potatoes, peeled and quartered
  • 1 cup whole milk
  • 8 oz cream cheese, softened
  • 1 cup (2 sticks) unsalted butter, cut into pieces
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 cup shredded sharp cheddar cheese, divided
  • 1/2 cup sour cream
  • 4 slices bacon, cooked and crumbled
  • 2 green onions, sliced for garnish

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. 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 completely. Return them to the hot, empty pot over low heat for one minute, stirring constantly to dry them out slightly. This prevents gummy potatoes.
  4. Remove the pot from the heat. Add the milk, softened cream cheese, butter, salt, and pepper. Mash the potatoes until smooth, incorporating the dairy and fat completely. For extra creaminess, use an electric mixer on low speed until just combined. Do not overmix.
  5. Stir in the sour cream and half of the shredded cheddar cheese until blended.
  6. Transfer the mashed potato mixture to the prepared baking dish. Sprinkle the remaining cheddar cheese evenly over the top.
  7. Bake for 20 to 25 minutes, or until the topping is melted and lightly golden brown.
  8. Remove from the oven. Sprinkle with crumbled bacon and sliced green onions before serving hot.

Notes

  • For the fluffiest texture, use a potato ricer or food mill instead of a standard masher.
  • You can prepare this casserole up to 24 hours ahead. Cover and refrigerate. Add 10 to 15 minutes to the baking time if baking from cold.
  • Use full-fat dairy products for the richest flavor and texture.
