read the instruction book. I know that sounds like a smart-*** reply, but I had to screw one up before I read the instructions.
Coat the inside with spray- I prefer butter flavored crisco. Season like a fried turkey
I'm cooking a 12 lb turkey as we speak. It's really easy. Just season however you want it and cook to a minimum internal temp of 165. I've never done just a breast before so I'm not sure how long it will take.
