whipped mashed potatoes :: make a day ahead :: crockpot :: recipe

Print pageEmail page

What goes with nearly every dish? Mashed potatoes! I’m going to give you the super-sized potluck recipe I make, but you can scale it down to feed your family on any ol’ night of the week. I hope this recipe finds you in time to try it for Thanksgiving or Christmas gatherings this year.

Bonus points for this recipe:

  • make a day or two ahead of time
  • garlic or regular, you decide
  • reheat well if you have any leftovers
  • heat, transport, and/or serve from your crockpot

A frugal shopping tip: I buy all my ingredients at Costco when I’m making a mass quantity because I can get a 20 lb. bag of potatoes, butter, and a tub of sour cream for about $15 and it will feed about 30 people really yummy mashed potaters.

Whipped Mashed Potatoes – serves 15 (one filled crockpot)

whipped mashed potatoes :: make a day ahead :: crockpot :: recipe
Recipe type: side
  • 10 lbs. russet potatoes (washed and peeled)
  • 2-3 sticks of butter (1 - 1 .5 cups)
  • 16 oz. sour cream
  • Season Salt and Pepper (season to your desired taste)
  • (if you want them to be garlic potatoes, add 2 tablespoons of minced garlic)
  1. Start a BIG pot of boiling water, then wash and peel your potatoes. Cut into cubes and boil until tender. Drain water and put ½ of potatoes in your Kitchen Aid mixer (or you can use your hand mixer in a big bowl). *Don't overfill your bowl, that's why I do half at a time* Add 1 stick of your butter, 8 oz. of your sour cream, 1 TB (or more) of minced garlic (optional), salt and pepper (to taste). Whip them with your mixer. Yup, no mashing, let your mixer do the work! When they are done and are seasoned to your liking, put the potatoes in your crockpot and repeat with remaining ingredients. Serve immediately OR put in refrigerator up to 1 day before serving.
  2. When heating potatoes from the refrigerator, turn crockpot on high for 2-3 hours to reheat. Also, cut up another stick of butter into cubes and stir into heated potatoes if they seem too dry. More butter is always delicious either way. You can stir them occasionally when heating to speed it up. The crockpot may form a crusty edge of potatoes (which is tasty) if it's on high for too long so once they are hot, turn to warm or low.
  3. *If you need to heat the potatoes faster you can always pop them in the oven covered with foil at 350 to reheat as well. Takes about 45 minutes. My crockpot bowl is oven safe so after the oven heats them I put it back in the liner to keep warm, serve, or transport. Be careful not to burn yourself though!
Make a day or two ahead of time as garlic or regular, you decide. Reheat well as leftovers.


To reheat your potatoes, just turn the crockpot back on the next day and they are just as delicious as the day before.

Crowds for dinner or potlucks can be intimidating. This recipe can be made a day in advance which helps out the cook who may have other items to prepare when having a big gathering. You also can use your crockpot to heat and serve your whipped potatoes which frees up your stove and oven and makes for easy transport too. Maybe we should all take a moment and pin this recipe for Thanksgiving!

Has anybody ever tried freezing leftover mashed potatoes? I want to try it, but with this recipe…we never have leftovers. 🙂

    This is a great idea especially for holiday or large meals. I always have to save making the potatoes until right before the meal so they will still be hot but this is great to be able to make ahead. Thanks!

    This is a great idea! You make mashed potatoes the same way I do (mine is a way smaller scale..it is just me and the fiance’) but I have never used the crockpot.Thanks for sharing!

    I can hardly wait for our Thanksgiving meal, but we make our mashed potatoes more special by adding cream cheese instead of sour cream.

    This recipe sounds so amazing! I’ve heard of sour cream in mashed potatoes before but never tried it! Wish I could try this for Thanksgiving but someone else is in charge of the mashed potatoes. Will be trying for dinner sometime soon though! Yummy! 😀

    Mashed potatoes are my FAVORITE! I have never used sour cream before but it makes so much sense. Mines always end up lumpy and it’s embarrassing so I usually don’t make them. You solved my issue! Thanks for the share!
