Mashed Potato Souffle

Topped with sharp cheddar cheese and whipped cream, this family recipe from TV chef Sarah Mastracco is a luscious side dish.

  • servings: 6

Ingredients

  • 4 tablespoons unsalted butter, plus more for baking dish
  • 5 pounds russet potatoes, peeled and halved crosswise
  • 1 cup milk
  • 1/2 cup sour cream
  • 4 ounces cream cheese, room temperature
  • Coarse salt and freshly ground black pepper
  • 1 1/2 cups heavy cream
  • 6 ounces sharp or extra-sharp cheddar cheese, grated on large holes of a box grater
  • 3 tablespoons fresh chopped chives

Directions

  1. Step 1

    Preheat oven to 350 degrees. Butter a large shallow baking dish; set aside.

  2. Step 2

    Fill a large pot with 2 to 3 inches of water; set a steamer insert into pot and add potatoes to insert. Cover and steam potatoes until tender and easily pierced with the tip of a sharp knife, about 15 minutes. Pass potatoes through a ricer into a large bowl.

  3. Step 3

    In a small saucepan, heat butter and milk over medium heat until butter is melted. Add milk mixture to potatoes, along with sour cream, cream cheese, 1 tablespoon salt, and pepper; fold to combine. Transfer potato mixture to prepared dish.

  4. Step 4

    In a medium bowl, whisk heavy cream until medium peaks form. Fold in cheese and season with salt and pepper; spoon cream over potatoes, spreading evenly to cover. Transfer to oven and bake until potatoes are heated through and top is light brown, about 30 minutes. Let stand 10 minutes; garnish with chives and serve.

    I made this a few days after it aired. My family loved it. My husband said every holiday you make something new, and it's always delicious.

    I made this as the side dish for our Christmas prime rib dinner, it was delicious!! Everyone loved it, I will be making it again and again! One note, don't over fill the dish like I did or you will have it running all over the bottom of your oven. Oops!

    ***** 5 stars I placed the ingredients in 8 indivual dishes and topped with the whipped cream and cheese topping. All puffed up and browned nicely. Very rich and elegant side dish. They held well in frig overnight and I baked them off next day.
