Our church is planning a potato bar to be served after our Ash Wednesday service. We are planning for 150 to 200 people. We do not have a commercial grade oven so we were wondering if we could put them in roasters. Would this work? Should they be wrapped in aluminum foil? How long would they need to be in roasters?
Bake until the internal temperature of the potato is 210°F. It takes about 1 hour at 400°F in a conventional oven, so you will have to adjust as necessary if you use roasters. Don’t wrap in foil to bake the potatoes—this just steams the potato and makes the skin soggy. You can wrap them after baking if you want to keep the potatoes hot.
