Nesco 18 quart roaster oven?
We have the older Nesco Roast Air (has a little convection fan in the lid). Yes, we have roasted turkey in ours. I has always turned out quite well although the skin is not as crisp owing to the roaster trapping moisture. We have also roasted large cuts of beef. And we have used it as a large slow cooker. Works real fine. So go ahead and use yours. You can likely get recipes off the Nesco site.
