This year I am thinking of making mashed potatoes ahead of time and baking them on Thanksgiving. I found several recipes on line and it looks like the answer to the last minute dinner preparation. Has anyone done this and what do you think? TIA

Re: Make Ahead Mashed Potatoes

Yes, I have made the mashed potatoes ahead of time, but kept them warm in the crockpot.

Great idea to save time.  Whenever I have leftover mashed potatoes, I just add a bit more plant milk before heating in the oven/stove as they tend to dry out.  They are just as yummy the second time around.  Happy Thanksgiving!

Here's a recipe I've actually put together ahead, frozen then thawed and baked on the day using them. They don't have to be frozen but I gave it a whirl and they were fine. Otherwise just make them a day or two ahead, I've done that more than once as well.


5 lbs potatoes boiled & mashed


1/2 cup of half & half

half cup of sour cream

8 ounces cream cheese softened

1 stick of butter

1 teaspoon onion powder

1 teaspoon salt

1 teaspoon pepper

sprinkle w/paprika

Bake at 350 degrees for 45 minutes

Re: Make Ahead Mashed Potatoes

I do this every holiday to save time on the day.  The night before:


Yukon Gold potatoes

Half & half at room temperature

salt & pepper

butter; salted or unsalted, melted and cooled

Use the amount you need.

Make the potatoes and put in generously buttered baking dish.  Put foil over and refrigerate.


Next day take out & let sit at room temp 1 hour. Put covered dish in 350 oven for about an hour.


That's it.  I do it every holiday.  They come out really creamy.

Should be fine.  I never make just one day's portion of mashed potatoes.  On subsequent use, I've baked them or made cakes to fry.  When I bake, I add a little milk and/or a small amount of extra butter.  Sometimes I top the casserole with freshly grated Parmesan -  pretty and yummy!

Re: Make Ahead Mashed Potatoes

Mashed potatoes are not time consuming to make at all.  It would probably be more work to make them ahead of time and have to rewarm them. And they never tast as good warmed up IMO.


I just peel and cube potatoes and soak them in salted water in the pot I plan to cook them in. For holidays, that means about 15 lbs of them.  If done the night before, I put the pot in the fridge. If the same day, I leave on the cold stove.


When ready to make, I just boil, mash and serve.


Sometimes, I have cubed raw or sliced potatoes in gallon zip lock bags with water added in my fridge.  I can get dinner ready in a jiffy.  I just remove what I need and cook.  The part i don't like is peeling and cutting them.


When I was a kid, we had mashed potatoes about 5 days a week.  It was my job to make them, so I am an old pro.

Re: Make Ahead Mashed Potatoes

i make mine the day before.  i just boil the potatoes(with salt) and then mash without any additions.  place in fridge until ready to use.(covered) when you aready to serve them just add milk, butter or what ever you like and the rerheat in the microwave until really warm..


it t he dairy that makes leftover mash potatoes have an off taste.  i make this all the time and you can not tell that they were made the day before

Re: Make Ahead Mashed Potatoes

Yes, I do this for any holiday meal.  I have a couple of different recipes and use my crock-pot.  It frees up time cooking on "day of" and frees up stove as well.  Very good!
