Can You Freeze Sweet Potatoes?
Yes, but only after cooking: bake, boil, or mash sweet potatoes until tender, then freeze them. Raw tubers hold too much water and turn mushy and grey once thawed, so the flesh must be cooked first. Properly packed cooked sweet potatoes keep their flavor for many months and reheat well from frozen.
