Home – Questions and Answers 2 – Frozen Potatoes Can you eat a potato that has been frozen? Can you eat a potato that has been frozen?I have a row of potatoes (Russets) that went through a frost. I pulled them out a few days later and then put them in the garage. They may or may not have been frozen since then. My question is this… What should I look for as an unsafe potato? They appear to still be in sound shape. Normally the potatoes need some time, like a month or 2 at least, before getting them from the soil after the frost period. They could probably be eaten but the quality of the potatoes is going to be drastically reduced. You can look for things like black or green spots to see if they are safe to eat.
