My recipe for make-ahead mashed potatoes uses three simple ingredients including potatoes, a little butter and milk.
No sour cream.
No cream cheese.
There are many mashed potato recipes out there and plenty of reheating methods one could follow.
But for those spud lovers out there who just want a foolproof recipe, just follow the mashed potato recipe card below and read the tips ahead of time.
Can you make mashed potatoes ahead of time?
Like me, I’m sure you’re busy in the kitchen preparing everything else that must go on the holiday table.
And you know the expression, “Too many cooks in the kitchen.”
That’s why I will whip up a pot of mashed potatoes days ahead and finish them off just before the Christmas or Thanksgiving dinner.
That way I eliminate the mess, finishing the dish at the last minute and it makes for easy cleanup. Plus I maintain my sanity.
The trick is holding off on the butter until you are ready to serve.
Once you are ready to serve, it’s time for the creamiest potatoes.
For best results follow my favorite method and these tips for making creamy potatoes
- Stick with Russet or Yukon Gold potatoes.
- Place your potatoes in cold salted water then bring to a boil.
- Never leave boiled potatoes in the water. Drain them immediately.
- Use a potato ricer or masher and don’t over mash.
- The more fat in your milk or cream, the creamier your potatoes will be.
- Warm the milk and butter before adding to the mashed potatoes.
Store the potatoes in an airtight container in the fridge for stove top or crockpot rewarming or in an oven safe baking dish for oven rewarming.
How to reheat mashed potatoes on the stove top
Place the cold potatoes in a large pot on the stove top on medium heat.
Melt the butter in the microwave or in a small saucepan.
Drizzle in the butter as you stir the potatoes from the bottom of the pan.
Once the potatoes have warmed, are easy to stir and light and creamy, transfer to a serving bowl.
How to reheat mashed potatoes on the slow cooker
Melt the butter first. Place the cold potatoes in the crockpot on low heat.
Reheat slowly adding the butter as you stir occasionally.
The reheating time takes a while to warm but is the easiest way to reheat potatoes.
Once the potatoes are warm throughout, give the potatoes a quick stir and they are ready to serve.
How to reheat mashed potatoes in the oven
Store the make ahead mashed potatoes in a even layer in baking dish so they can go right in the oven when rewarming.
Preheat the oven to 350 degrees F. While the oven is warming melt the butter.
Add a splash of milk and the melted butter to the potatoes and bake until they are heated throughout to an oven temperature of 165 degrees, about 20 – 30 minutes.
Why are my Yukon Gold mashed potatoes gummy?
To prevent mashed potatoes from having a gluey texture, you must stay away from a blender, mixer or food processer.
Overworking the boiled potatoes will result in too much starch being released and will yield gummy and glue-like potatoes.
Use a potato masher or rice peeler instead and avoid repeated stirring.

This is such a great timesaving tip. I’ve only ever made mashed potato when I’m ready to eat it – but great to know holding off the butter until you’re ready to serve them means you can cook the potatoes ahead!
Any way I can save time in the kitchen during holidays I do. Holidays are a time for families and while kitchen time is fun, limited kitchen time is better. ?
I love when you can make any part of dinner ahead of time!
Me too. Thanks Kristina.
What a time saver! I never thought of making the mashed potatoes ahead. That will free up my stove for other pots!
Anyway you can free up space in the kitchen I’m off for. Thanks Leslie.
Love that I can save space and not skip on flavor this holiday season.
Thanks Jacque. This recipe promises not to skip on flavor. Just time. ?
I agree holiday time is for our family not for cooking recipes through out day. love this recipe.
Any way I can spend less time in the kitchen is a recipe winner in my book. Thanks Rachna 🙂
I am planning our family Thanksgiving meal now and plan on using this recipe to serve 16. I tend to be very detailed oriented in all things and need to know what total weight of potatoes is this recipe (milk and butter quantities) designed for. There is a huge variance in the weight and size of individual potatoes so are the milk and butter quantities stated for 8 to 10 potatoes actually 4 lbs., 5 lbs., or what?
This is about 5 pounds of commercial sized potatoes from your local grocer. Happy Thanksgiving!
