Roasting potatoes at a lower temperature

Q: Can I roast sliced potatoes at 250 degrees and if so, for how long?
A: Yes, you can roast potatoes at a lower temp, but it will take longer. I can’t tell you how much longer without specifics, such as size of potato or baking dish. The thicker the dish is, the longer you will need to cook the potatoes. You might start at adding 10 to 15 more minutes.
