Make-Ahead Mashed Potatoes

Mashed potatoes are a Thanksgiving must. If your space in the kitchen is limited, or you have been asked to bring the mashed potatoes to somebody else’s house, or if you just like to be organized and get things prepped ahead of time, here is a tried and true recipe you can count on.

Make-Ahead Mashed Potatoes can be made days in advance and kept in the refrigerator or even frozen until you need them. Just reheat in the oven for 50 minutes prior to serving and voila – fluffy, buttery mashed potatoes!

Make-Ahead Mashed Potatoes


  • 5 lbs. russet style potatoes, peeled and cut into 2" chunks
  • 8 oz. cream cheese, softened
  • 1 cup sour cream
  • salt and pepper (white or black) to taste
  • 4 Tbsp. butter



  • Place the potatoes in a large pot of salted water. Bring to a boil and cook until the potatoes are tender – approximately 25-30 minutes. (The potatoes should be soft and fully cooked and slightly crumbly, but not falling apart). Drain the potatoes and return them to the pot.


  • Using a potato masher or a hand-held electric mixer, mash the potatoes with the cream cheese and sour cream until well-blended and fluffy.
  • Season to taste with salt and pepper.
  • Transfer the potatoes to a lightly buttered 9″ x 13″ casserole dish. If serving immediately, dot with butter and bake at 350 degrees, uncovered, for 20 minutes.


  • At this point, the potatoes can be refrigerated for several days or even frozen. Wrap the dish very well with plastic wrap until ready to use.
  • Before serving, bring the potatoes to room temperature for 30 minutes. (If frozen, thaw in the refrigerator overnight first).
  • Dot with butter, then bake, uncovered, for 50 minutes or until heated through.
