Woohoo! Got the go ahead from my wife to try it this weekend. I can't wait, the bird is defrosting as we speak.
Totalcolour, what temperature and how long in the oven?
Low and slow - I did mine at 325f and I'm not sure of the time. I did it on it's breast first, then one side, then another side, then breast up (about 15 minutes per side). I Seasoned it and sprayed with grapeseed oil (I have an oil mister). You can use olive oil, but I didn't want to affect the taste, and grapeseed is very bland.
I don't know how big your bird is, so you could use a thermometer. I did all the veggies ahead of time so I wouldn't have to worry about the bird being "on time"! Me, I just figured it was done when it was nice and golden all over. (Best guess recollection was 1 hour 20 mins, but I can't remember how big the chicken was so it's not much help.) {But for me, a boned, stuffed bird is "usually" 15 minutes a pound + 15 minutes at the end.}
Thing is, with a boned bird, you don't get all the variation with the leg and thigh versus breast - it cooks much more evenly. If it's getting very brown before you think it's cooked through (maybe it's a big bird), just cover it with foil, or a lid, and cook a bit longer, or turn down the heat. But, there shouldn't be much variation with time per pound.
Also, I sauteed the celery and mushrooms before stuffing. If you are using a meat stuffing, it will need to cook a bit longer to make sure the meat stuffing is cooked.
I'd wish you good luck, but I don't think you need it. This is such an easy way, and I don't think you will be disappointed. (Don't put in much salt, it draws the moisture out and makes it tough; add salt at the table!)
Oh, and while it's cooking, don't forget to use the carcass to make a nice sauce or chicken stock for the pantry - your wife will love you!
