I always do red cabbage, gravy and stuffing balls in advance. Cranberry sauce sometimes if I can be bothered, but mostly buy a jar.
if your budget stretches to a Kelly bronze turkey, the cooking time on the day is much shorter which I find means I spend a lot less time in the kitchen.
we usually have either soup or a festive terrine as a starter, both easy to prepare ahead.
Instead of dessert, we have a cheese board, Christmas cake and Nigella’s Christmas rocky toad. The Christmas cake is done and I’ll do the rocky road a few days in advance.
i peel potatoes and other veg on Christmas Eve. I’ve tried various methods of doing more in advance but never found it worth the effort.
on the day it’s turkey in the oven, get everything ready to go on, take turkey out, put potatoes in, then other veg. Heat up gravy in microwave, red cabbage on the hob and we are good to go.
