I learned this trick from a friend, and we all love it: roast the turkey, stuffing, and make the potatoes the day BEFORE. Clean the turkey, then layer in a large baking pan the potatoes, stuffing, then turkey on the top. I do 1/3 dark, 2/3 white meat. Make the gravy, pour over the top. Cover and refrigerate, clean up all those dishes, and go to bed.
The next day, heat the casserole through, there's plenty of room in the oven for the sides, and your day is so much more relaxed. Cleanup is a breeze, and I enjoy my day SO much more.
