Perfect for the busy holidays, these ultra-creamy make-ahead mashed potatoes can be prepared two days ahead of time and reheated in the microwave.
As much as my family loves buttery, gravy-drenched mashed potatoes on Thanksgiving, I’ve always been hesitant about making them because they need to be prepared at the last minute. Traditional mashed potatoes don’t hold up well when made ahead of time, often becoming dry, grainy, or even gluey—a real letdown for such a special occasion. The thought of mashing potatoes in the eleventh hour, while juggling a dozen other dishes in a kitchen buzzing with guests of all ages, is nerve-wracking, to say the least! That’s why I was thrilled to discover a method for make-ahead mashed potatoes from Cooks Illustrated that works really well. Not only do these mashed potatoes stay ultra-creamy, but they can also be made up to two days ahead of time and reheated in the microwave—a huge bonus when oven and burner space is at a premium during the holidays.
“I’ve always dreaded making mashed potatoes on the day of Thanksgiving. Too much work and mess, and they never seem to come out the way I want them to. These make-ahead mashed potatoes were the perfect solution! And they were so creamy and delicious!! They got rave reviews from my family and definitely earned a permanent spot on my Thanksgiving menu!”
What You’ll Need For Make-Ahead Mashed Potatoes
Interestingly, the recipe calls for baking the potatoes instead of boiling them. In all my years of cooking, I have never seen a mashed potato recipe that starts with baked potatoes. But it makes sense: water is the enemy of perfectly mashed potatoes. If the potatoes are too wet, they become dense and heavy. (That’s why most recipes instruct you to “dry” the boiled potatoes on the stovetop before adding the butter and liquid.) In many ways, the recipe is similar to twice-baked potatoes, which can also be made mostly ahead.
Baking the potatoes does take longer but it’s a tradeoff: you don’t have to peel or dry the potatoes and it’s completely hands-off. And since the potatoes cook directly on the oven rack, you won’t even dirty a pan!
How To Make Make-Ahead Mashed Potatoes
To begin, place the potatoes directly on an oven rack and bake until very soft, 50 to 60 minutes. While the potatoes are still hot, cut each in potato in half lengthwise. Scoop out all of the flesh from each potato half into the bowl of a stand mixer fitted with the paddle attachment (or the bowl of an electric mixer). Break the cooked potato flesh down into small pieces using a fork, potato masher, or rubber spatula.
Beat on low speed until completely smooth and no lumps remain, stopping the mixer to scrape down the sides and bottom of the bowl as needed. It’s important to do this while the potatoes are still hot, otherwise you’ll end up with lumps.
Meanwhile, in a small saucepan, bring the cream and butter to a simmer.
Remove the bowl from the mixer. Using a large rubber spatula, gradually fold in the hot cream and butter mixture. Folding (rather than stirring in the stand mixer) prevents the potatoes from becoming gluey.
It will take a few minutes to mix the liquid in; keep folding until the potatoes are smooth and creamy. Mix in the salt, then taste and adjust seasoning, if necessary.
Transfer the mashed potatoes to a large microwave-safe bowl and cover tightly with plastic wrap. Refrigerate for up to 2 days. To reheat, poke lots of holes in the plastic wrap with the tip of a knife and microwave at medium-high (75 percent) power for about 14 minutes. Stir the potatoes halfway through reheating to be sure they warm evenly. Season to taste, then transfer the potatoes to a serving bowl. Top with the remaining 2 tablespoons of butter and the chives and serve warm.

Perfect for the busy holidays, these ultra-creamy make-ahead mashed potatoes can be prepared two days ahead of time and reheated in the microwave.
Ingredients
- 3½ pounds Russet potatoes
- 2 cups heavy cream
- 8 tablespoons unsalted butter, divided
- 1½ teaspoons salt
- Chives, for serving
Instructions
- Preheat the oven to 450°F and adjust an oven rack to the middle position.
- Prick each potato a few times all over with a fork, if you like (see note). Place the potatoes directly on the oven rack (alternatively, you can place them on a wire rack set in a rimmed baking sheet). Bake until very soft, 50 to 60 minutes, depending on the size of the potatoes. (Err on the side of overcooking rather than undercooking them.)
- Remove the potatoes from the oven. While they are still hot, cut each potato in half lengthwise. Using an oven mitt or a folded kitchen towel to hold the hot potatoes, scoop out all of the flesh from each potato half into the bowl of a stand mixer fitted with the paddle attachment (*see note below on using a potato ricer, food mill or hand-held electric mixer). The flesh near the skin gets a little tough, so be sure to leave it behind. Break the cooked potato flesh down into small pieces using a potato masher, fork, or rubber spatula. Beat on low speed until completely smooth and no lumps remain, 1 to 2 minutes, stopping the mixer to scrape down the sides and bottom of the bowl as needed. (Note: it’s important to mash the potatoes while they are still hot, otherwise you’ll end up with lumps.)
- Meanwhile, in a small saucepan over medium heat, bring the cream and 6 tablespoons of the butter to a simmer.
- Remove the bowl from the mixer stand and, using a large rubber spatula, gradually fold in the hot cream and butter mixture. It will take a few minutes to mix it all in; keep folding until the potatoes are smooth and creamy. Stir in the salt, then taste and adjust seasoning, if necessary. Transfer the mashed potatoes to a large microwave-safe bowl and cover tightly with plastic wrap (the bowl should be large enough that the potatoes don’t touch the plastic wrap). Refrigerate for up to 2 days. (DO NOT FREEZE)
- To reheat, use the tip of a knife to poke about 10 holes in the plastic wrap, and microwave at medium-high (75 percent) power until the potatoes are hot, about 14 minutes, stirring halfway through the reheating time. Taste and adjust seasoning, if necessary. Transfer the mashed potatoes to a serving dish, top with the remaining 2 tablespoons of butter, and sprinkle with the chives. Serve hot.
- Note: Conventional wisdom says that prior to baking, you have to prick potatoes with a fork a few times to allow steam to escape during baking. The theory is that if you don’t prick the potato, the steam can build up under the skin and cause the potato to explode in the oven. I don't prick my potatoes and have never had a potato explosion, but pricking won't harm the potatoes, so go ahead and prick them as insurance, if you like.
- Notes: For perfectly smooth potatoes, pass the potato flesh through a potato ricer or food mill before adding them to the mixer. If you don't have a stand mixer, you can use a hand-held electric mixer. If you don't have an electric mixer, pass the potatoes through a food mill or potato ricer and then whip by hand with a wooden spoon.

These were the bomb! Great texture and taste. Plus they saved me so much time on Thanksgiving. Thank you so much!
I made this recipe on the Tuesday before Thanksgiving and I have to say it was delicious and just perfect! At first, it seems like there will be too much liquid, but the potatoes set up in the refrigerator. I didn’t notice any gluey or grainy texture that others mentioned at all. I followed the recipe with no changes – except I used light cream.
It was a breeze to heat it up in the microwave just before Thanksgiving dinner. Very grateful to have one less complex recipe to follow on the big day. Thank you for this recipe!
I’ve always hated making mashed potatoes on the day of Thanksgiving. Too much work and mess, and they never seem to come out the way I want them to. These make-ahead mashed potatoes were the perfect solution! And they were so creamy and delicious!! They got rave reviews from my family and definitely earned a permanent spot on my Thanksgiving menu!! Thank you!!!
I made these for Thanksgiving and got so many complements on them!! They were a hit! I was worried once I poured the cream and butter mixture into the potatoes because it looked like too much, but they were perfect after folding! I served the mashed potatoes with your recipe for Beef Tenderloin with Red Wine Sauce and French Green Beans. Everyone LOVED it, and we fried the leftover potato skins the next morning for breakfast! Yum! Jenn, your recipes never disappoint!
I thought I made the best mashed potatoes but apparently I was wrong. These mashed potatoes were great. Everyone loved them and wanted the recipe. I doubled the recipe and followed the directions exactly except added a little garlic powder. There were no leftovers. I usually don’t write reviews but if you want a good make ahead mashed potato recipe I highly recommend this one. You won’t be disappointed.
I made these this year and the flavor was very good but, the amount of liquid made mine too runny. I’m surprised that I haven’t seen this as an issue with others. What could have gone wrong?
Hi Linda, sorry you found these to be too runny. Did you use heavy cream? And did you use the full 3-1/2 pounds Russets?
Hi Jen,
I like my mashed to have some structure so they hold the gravy and not be too thin/creamy.
Should I add just enough cream until I get the texture I want? I’m just not sure if they will thicken up when heating in the microwave (in which case, I will stick to the recipe).
Thanks in advance.
Hi Jay, these do thicken up a bit in the microwave, so I’d suggest sticking to the recipe. Hope you enjoy!
This has become a staple for holiday dinners. It is super easy to make ahead then heat the day of….we all love it.
Forget what you think you know about mashed potatoes. Make this recipe and you’ll never use another. They were the hit of Thanksgiving dinner. Potatoes! We make them the night before, so we broiled the leftover skins with cheese, bacon, and chives for a nice snack. An added bonus!
I’ve made these the past two years and they were excellent both times. I love not having to peel the potatoes. They are so hearty and stay together. We heat up leftover mashed potatoes for breakfast with chopped onion, eggs, and cheese. This year they were outstanding. Thanks for this great recipe.
