how long can cooked unrefrigerated sweet potatoes last
I cook several at a time and leave them on the counter and eat them all week without refrigeration and never had any problems. Ask someone old if they threw out cook sweet potatoes after a couple of day when they didn't even have an icebox 100 years ago. I slice off the ends and then cook them at 200^ for 1 hour and then 350^ until there are done. The longer they are between about 130 - 180 the carbs turn to sugar and are dripping by the end.
