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.
“This recipe yielded the smoothest mashed potatoes ever. This is my go-to mash now until I depart this earth.”
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.

Hi! Any chance I could substitute coconut cream for the dairy cream to make this a vegan dish? (I obviously would use plant butter too) Thank you!
Hi Lynn, I don’t recommend coconut cream here as it will give the potatoes a subtle coconut flavor. For a non-dairy option, some readers have commented that they’ve used Rich’s non-dairy coffee creamer (frozen) and Trader Joe’s unflavored non-dairy creamer. (Please keep in mind that I haven’t tried either of these.) I’d love to hear how the potatoes come out if you make them with one of these alternatives!
Thanks, Jenn! I took your advice and did not use coconut cream. I used Country Crock dairy substitute whipping cream. Seemed to turn out great but will know for sure tomorrow when I reheat.
Hope they come out well!
Yes they did! Delicious!
Hi- Want to try this TG. But, I’ve been warned off using a stand mixer for mashed potatoes–releases too much starch and makes potatoes gluey. Any advice about this? Thank-you.
Hi Anneka, f you use the method I do in the recipe and follow the directions carefully, the potatoes won’t come out gummy/gluey. Hope you enjoy if you make them!
Should the potatoes be scrubbed, dried and pierced before baking?
Yep!
I don’t have a mixer like yours. I don’t think a hand mixer or blender is a good idea. I suppose I can just use a potato masher as the next best alternative. I might have a little more lumps but at least it won’t be gooey. Do you agree?
Sure, Cynthia, you can do this by hand with lots of elbow grease. Enjoy! 🙂
This is a keeper recipe and worthy of TG Hall of Fame. Heard a nice time saver: to more quickly separate the potato from the skin, put a baking rack over a bowl and smash the potato flesh side down through the grates into the bowl. No more scooping 7 pounds of hot potatoes! Such a great recipe to take one more last minute mess out of the kitchen!
Can you use Yukon gold potatoes?
Unfortunately this won’t work with Yukon golds – sorry!
I used Yukon Golds today and it is absolutely delicious!! Skins were a little thin but scooped out just fine.
Why does baking the potatoes make them better than boiling the potatoes ?
Hi Ellen, baking the potatoes helps to dry them out more, which will give you a better finished product. Hope you enjoy if you make them!
I prefer dairy-free. Can I use coconut milk instead? Or, a lower fat dairy, such as half and half?
Hi Lori, I don’t recommend coconut milk here as it will give the potatoes a subtle coconut flavor. For a non-dairy option, some readers have commented that they’ve used Rich’s non-dairy coffee creamer (frozen) and Trader Joe’s unflavored non-dairy creamer. (Please keep in mind that I haven’t tried either of these.) I’d love to hear how the potatoes come out if you make them with one of these alternatives!
I have made this delicious no fail mashed potatoes last two Thanksgiving Holidays. They were the biggest hit! I love scooping rather than peeling. Recipe is a winner & I get requests all year long. I am pretty sure I put them in a 9X13 dish. This year I am making 1 1/2 recipe, If I put that amount in a 9X13 dish how long to reheat in the oven?
Thanks Terri
So glad they’ve been a hit! I’d guesstimate that Half the recipe would take about 20 minutes to reheat.
Oh my! These mashed potatoes were worth every extra minute on the treadmill! Gave this recipe a try and had to make a double batch for supper the following night! There were no leftovers!
I never considered baking the potatoes instead of boiling them. Makes sense and these mashed potatoes were just perfect. Of course, doesn’t everything go better with butter and whipping cream!? lol
Appreciate you sharing the recipe and the method!
Your receipes are always so good. I shall do this come Christmas..thank you
