This Mashed Potato recipe is a life-saver on the holidays. Before I discovered this recipe the Mashed Potatoes were always one of the last dishes I made on the holidays. Even though Mashed Potatoes are a fairly simple recipe it’s stressful trying to mash the potatoes at the same time you’re getting the Roast Turkey, Cranberry Sauce, Stuffing, and other dishes ready.

This Potatoes recipe takes one thing off your plate on the day of, which on a busy holiday with lots of guests and dozens of recipes to cook, can make all the difference. With the potatoes already mashed in advance, all you have to do is pop them in the oven to heat up for a stress-free side dish.

  • Cook Potatoes: If you don’t want any peels in your Mashed Potatoes start by peeling the potatoes. Then cut them into chunks, and put the potatoes in a large pot. Pour water over the top, enough so there’s about an inch of water above the potatoes. Turn the stovetop to medium heat and bring to a boil. Continue to cook the potatoes for 18-20 minutes. You can test if the potatoes are tender with a fork. Drain the water out of the pot.
  • Mash: Use a hand-held potato masher to mash the potatoes. Continue to mash until they reach the consistency you prefer for Mashed Potatoes.
  • Cream: Stir together the cream cheese, sour cream, heavy cream, butter, salt, and pepper in a saucepan over medium heat until smooth. Pour the mixture over the mashed potatoes and continue to mash until the cream is worked into the potatoes.
