Hi. Welcome. The turkey is done when the thigh meat reaches 180 degrees. You can find approximate times on the package or on line, but the true way of knowing when it is done is by checking the temperature. Also, don't forget that if you stuff the turkey it will take longer to roast. In the roaster oven be sure not to add any liquid, or you won't have a brown turkey. I also put paprika on my turkey if I use the roaster oven. I actually prefer to use the oven where the turkey gets a beautiful brown.
No matter where I serve my guests, it seems they like my kitchen best
