Chips from raw potatoes about 20 mins @180c. I don’t know about the steak as I always coat mine in oil, salt n pepper and fry on a very hot dry frying pan, but I would think around 15 mins for steak. My energy monitor suggests it uses between 4p and 7p an hour to use it. My oven @180c costs between 55p and 75p an hour.
