I overbought and now have a LOT of potatoes, probably 10-12 lbs.
Funny how things can have such different meanings for different people, lol! I bought 10 lbs. of potatoes last week at Aldi's ($1.19 for 5 lbs.) and I'm thinking that I should have bought MORE!! ;-)
I really don't have any ideas for you on freezing mashed potatoes; I've never tried it. As for using them up, my only suggestion is serving them different ways--mashed, baked, seasoned potato wedges, potato soup, etc.--with several meals over the next week. Somewhere I've seen a way to make your own shredded frozen hash browns, but I can't remember where now. (You could probably google it and come up with how-to.)

You can freeze mashed potatoes if you add cream cheese or sour cream to them.
My dh doesn't like reheated frozen mashed potatoes, for just that reason...but they don't bother me.
In addition to mashed potatoes, I
This time of year we store extra potatoes in the garage where it's cool. They last pretty well out there and give us adequate time to use them.
Whether you store potatoes in the house or out in a cooler location, try taking them out of the plastic and putting them in a brown paper bag or cardboard box. They last better this way and don't sprout quite as readily for some reason.
LOL... I go through 10 lbs. of potatoes every 2 weeks. Must be because we're Irish. :-)
Dice some up and make home fries for breakfast. Use any leftovers in potato casserole with cream of mushroom soup, onions and cheese.
I baked whole potatoes and have them frozen in my freezer. If I need to add something to a lunch or just want one for lunch, I take it to work and by lunchtime it's thawed. I usually have a small container that I put in a bit of butter, sourcream, shredded cheese, bacon bits, or whatever I have on hand for toppings. I think they taste fine - I cut it up and microwave for about a minute or so. They would also be easy to add to soup as someone mentioned.
