Can You Freeze Sweet Potatoes?
Yes, you can freeze it.
10-12 months (cooked only)
Raw sweet potatoes share regular potatoes' freezer limitation — only the cooked form holds up well, since freezing a raw, dense root vegetable produces the same watery, grainy texture problem seen with white potatoes. Roasting or boiling first, then freezing, gives a genuinely usable result for later use in a casserole or mash, whereas skipping that step and freezing raw sweet potato simply doesn't work.
Sweet potatoes that have been roasted whole, skin-on, before freezing hold their texture and flavor a bit better once thawed than ones that were peeled, cubed, and boiled first, since roasting concentrates their natural sugars rather than leaching some of them into cooking water the way boiling does.
An orange-fleshed sweet potato and a white or purple-fleshed variety both follow the same cook-before-freezing guidance, though the different varieties can vary somewhat in natural sugar content, which affects how much they caramelize during roasting before that roasted result ever goes into the freezer.
Cubed raw sweet potato can also be frozen after a brief blanch, rather than fully cooked, if the goal is a quicker-cooking frozen ingredient for a stew rather than a ready-to-eat mash — the blanch alone won't give as smooth a result as fully roasting first, but it's a reasonable middle option for a cook who wants more flexibility in how the thawed sweet potato is later prepared.
A sweet potato roasted with its skin left on retains a bit more of its natural moisture during cooking than one peeled before roasting.
