The Ultimate Creamy Make-Ahead Mashed Potatoes

The beautiful, golden-brown Mashed Potato Casserole being served as a centerpiece on a festive Thanksgiving dinner table.

A recipe for extra rich and creamy mashed potatoes that are finished in the oven. Yukon gold or russet potatoes are boiled until tender, then mashed over low heat to release excess steam. A decadent mixture of butter, cream cheese, half-and-half, and cream is incorporated to create a silky-smooth texture. The potatoes are then transferred to a casserole dish, dotted with more butter, and baked until hot and golden on top, making them a perfect make-ahead side dish.

Ingredients

Scale
  • 5 pounds Yukon gold or russet potatoes, peeled and quartered
  • 1 1/2 sticks (12 tablespoons) softened butter, plus more for the dish
  • 1 1/2 (8-ounce) packages (12 ounces total) cream cheese, softened
  • 1/2 cup half-and-half
  • 1/2 cup cream
  • Salt and freshly ground black pepper
  • Milk, if needed for thinning

Instructions

  1. Preheat the oven to 350°F.
  2. Place the peeled and chopped potatoes into a large pot and cover with cold water. Bring to a boil and cook for 20 to 25 minutes, until the potatoes are fork-tender.
  3. Drain the potatoes well and then return them to the hot, empty pot.
  4. Place the pot on the burner over low heat. Mash the potatoes with a potato masher for about 5 minutes, allowing steam to release as you mash. Turn off the burner.
  5. Add the softened butter, cream cheese, half-and-half, and cream to the mashed potatoes. Season with salt and pepper.
  6. Continue to stir and mash until all the ingredients are well combined and the potatoes are silky smooth. If the mixture is too thick, add a splash of milk to thin it to your desired consistency.
  7. Check the seasonings and add more salt and pepper to taste.
  8. Pour the mashed potatoes into a large casserole pan. Dot the surface with a few extra pieces of butter.
  9. Cover the dish with foil and bake for 15 minutes.
  10. Remove the foil and continue baking for 10 more minutes, until the top is lightly golden.
  11. Serve immediately.

Notes

  • Mashing the potatoes in the hot pot over low heat for a few minutes is a key step that helps to drive off excess moisture, resulting in a fluffier, less watery final product.
  • The combination of butter, cream cheese, half-and-half, and cream makes these potatoes exceptionally rich and creamy.
  • Baking the mashed potatoes at the end makes this a great make-ahead dish for parties or holidays.
