Well, they were on sale for .19/lb, and I got a little carried away. Now I have 30 pounds of sweet potatoes to use up, freeze, preserve, or give to my neighbors.
I like to dice and roast them with chili powder, salt/pepper, and a little cinnamon. I haven’t tried freezing them that way, but maybe I will. I suppose I can also bake and freeze the innards for mashed sweet potatoes, which I could use in various recipes or plain.
Now…what to do with the other 20 pounds?
You could use about 5 pounds to make a great big sweet potato pie.
I could sub mashed sweet potatoes for pumpkin in pumpkin bread, right? I could make a bunch of that and freeze it.
I have tomorrow off so I’m envisioning a sweet potato marathon!
they keep dry and cool. a tater a day.
As already well mentioned, sweet potato pie!
Sweet potato fries.
Baked sweet potato with lots and lots of butter.
Only .19/lb??? I need to shop where you shop. I love sweet potatoes.
Sweet potatoes make great french fries.
My family are all fond of my sweet potato bread, I’m sure you can find a recipe online to use. There’s also oatmeal sweet potato cookies with chocolate chips. (yeah, can you tell I had a surplus to use a while ago too?)
You could plant them under a couple of bales of spread out straw and have a bunch as needed next year. 
I make this (or very similar, without the whole peanuts) and it’s my Favorite Stew Ever!
carnivorousplant, can you elaborate? I can plant them now and just leave them over the winter, you mean? I’ve never planted any type of potatoes so I don’t have any experience.
I have a wonderful recipe for pumpkin soup that you could substitute sweet potatoes!
Ingredients: pumpkin/sweet potatoes, milk, sausage, onion, mushrooms, Italian seasoning.
Makes you want to hide in the closet with the pot and a spoon, and not share with anyone!

In central Arkansas, Zone 7, I’ve tossed Idaho potatoes on the ground in the fall, covered them with straw and harvested them in the spring. They were small, I boiled them and served them with white sauce.
The coldest it gets here is 20 F. YMMV
