I did it at 325 first hour, turned it up to 350 but it took forever for the internal temp to reach 170. So cooked about 2hr and not quite 30 min. It had been thawed out first. I turned it up to brown it a bit more, about 5 minutes. I think I like the thing!
I messed up the gravy packet though. It said not to remove the netting that was next to the skin. But when I tried to remove it after cooking, it came out in little tiny pieces. So to get the drippings I added some water and strained everything through a paper towel. Then you add that with 1 3/4 cup of water to the packet and cook together a few minutes. It tasted nasty so I didn't use it. I wasn't sure if they meant the total liquid would be 1 3/4 but I am betting it was supposed to be that way. I hadn't cooked just a turkey breast in a long time. It is good. We still have lots left! It was a Butterball that I got at Aldi's for $9.99, It will make easy leftovers for the weekend. I also got a Marie Callendar Chocolate satin pie. Yum!
