I have never bought a fresh turkey from the butcher. We always just get a frozen turkey and all works out well.
We buy it about a week before Tday, keep it in the fridge and the bring out the night before Tday to sit in the sink and thaw. (I know, I know, alot of people say they would never do this, but I have been doing for about twenty years and my family before me and the turkety has never made anyone sick).
My husband cooks the turkey. We go by the directions on the turkey package as to how many pounds it is and how long to cook per pound. He puts it into a roasting pan. Usually, even with a fresh turkey, I think it is about twenty minutes per pound. He puts some water in the pan, rubs the turkey with olive oil and adds some salt and pepper to the turkey. And that is basically it. He will baste it every so often, but that is it. He covers the pan with aluminum foil because our lid won't fit with the turkey and towards the end, removes the foil, so the skin browns nice and even. Easy peasy and we always get raves on our turkey. He said the trick is not to over cook the turkey. I think he sets the oven at 350.
I do most of everything else and I make as much as possible the night or the weekend before. Potato filling, mashed sweet potatoes with marshmallows, green bean casserole, corn pudding, (or in our area of Berks County, PA, Kopes corn in a can) and maybe another vegetable. I made fresh cranberry sauce once, nope. My family likes it from the can. Buy rolls and heat them.
I don't usually make pies, we buy them from Sam's club, (super yummy), but I found this pumpkin cake dessert I think I will make this year. It is yummy.
Gravy. Heck, never make fresh gravy. I suggest you buy it in a jar or can. Easy peasy. If your family does not like it, they can make the gravy.
Since there is so much for dinner, we really don't do salad or appetizers.
Just read your post about gluten free gravy, sorry. Did not know this. About just buying it in a jar or can. You could practice with a small turkey to get the gravy for your big meal and then add that gravy to your big meal.
