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’m always hesitant to make them because they’re typically a last-minute dish. Traditional mashed potatoes don’t hold up well when made ahead—they often turn dry, grainy, or even gluey, which is a real letdown for such a special occasion. And the idea of mashing potatoes at the eleventh hour, while juggling a dozen other dishes in a kitchen buzzing with guests of all ages, is downright nerve-wracking!
That’s why I was thrilled to discover a method for make-ahead mashed potatoes from Cooks Illustrated that works really well. These mashed potatoes stay ultra-creamy and can be made up to two days ahead of time. Best of all, they reheat perfectly in the microwave—a lifesaver 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!
Step-by-Step Instructions
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.
Reheating Instructions
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.
If you’d prefer to reheat the potatoes in the oven, transfer them to an oven-safe dish, cover tightly with foil, and bake in a 350°F oven for 30 to 40 minutes, stirring halfway through to ensure they heat evenly.

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. 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.
- 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.
- Oven-Reheating Instructions: If you’d prefer to reheat the potatoes in the oven, transfer them to an oven-safe dish, cover tightly with foil, and bake in a 350°F oven for 30 to 40 minutes, stirring halfway through to ensure they heat evenly.

I only have a hand mixer. Would it be okay to use that or to just use a ricer for the potatoes, whisk them a bit, and then fold in the cream and butter?
Hi Lindsay, I would use a ricer for best results. Enjoy!
Hello jenn , I just bought your book. Quick question can I boil the potatoes in water ?
Thank you for purchasing the book – I hope you find many new favorites in it! I think baking the potatoes is much easier, but you can boil them if you’d prefer; just make sure you dry the boiled potatoes on the stovetop before continuing on with the recipe. Hope you enjoy!
Would it be possible to use Yukon gold for this recipe?
Unfortunately, not Sandy – they may get gluey using this method. Sorry!
Hi Jenn,
We will have 29 people around the Thanksgiving table. Will this recipe work if I triple the ingredients? Thanks!
That’s a lot of guests! 🙂 Yes it can be tripled, but you’ll have to mix the potatoes in batches since they won’t all fit in the mixer at once. Enjoy!
Hello Jenn! Because of you, I can look like a good cook! Ha!
Question – I’m not hosting Thanksgiving and only have the assignment of mashed potatoes. I don’t need to make them ahead of time – can I still just follow this recipe to serve basically an hour later? Thank you for all you do!!!
Happy to play a part in making you look good! 😉
Yes, you can definitely serve these shortly after preparing them – hope you enjoy!
Thank you so much!! Have a wonderful holiday!!!
Hi! I can’t wait to try these potatoes! Question: will the paddle attachment on my stand mixer work the same as a ricer? Perhaps on a slow speed? Thanks!
Yes, Christina, the paddle attachment used on low speed is perfect here. Enjoy!
Could these be heated in the oven rather than microwave, and if so, stvwgat temperature and approximately how long would you sugges?
Hi Connie, These are best when reheated in the microwave, but you can reheat them in a 350°F oven, covered with foil, for 30-40 min (stirring once halfway through) or until warm. Hope that helps!
Hi Jen, I’m anxious to try this (baked) mashed potato recipe! I’ve always added SOUR cream and butter instead of heavy cream or milk to my mashed potatoes. Do you think Sour cream will work for this recipe? and would I heat it up first with the butter, a la recipe? Thanks.
Hi Alison, Make-ahead mashed potatoes are finicky so I can’t say for sure if it’d work without trying it. I’d stick to the recipe for best results. Sorry!
Hi Jenn! This recipe looks great! I am planning to make a double batch and would like to reheat in my slow cooker. Do you know if they turn out well using this method to reheat? Also approximately how long should this take to reheat on low? Thank you!!
Hi Kati, I never use a slow cooker, so I really can’t say how these would do being reheated in one. Since I’ve never tried it, I’m not sure how it would affect the texture. Sorry!
Can these be frozen several weeks ahead and reheated ?
Hi Peggy, I don’t recommend freezing these – sorry!
