How long does it take to bake potatoes at 275 degrees?

id say like cook it as long as it says to but then just let it cook a little longer and keep checking up on it until it looks done. I'd say cook it at what the recipie says, just so you don't mess up. But only the first time. 2nd time, lower the temp, but increase time. do this until you reach your potaoto is cooked
