We usually have a breakfast of scrambled eggs with smoked salmon on German grain bread, with Buck’s Fizz. Pandora on the side for those who want it.
Lunch is a buffet of pork pies, cheese board, patè, chutneys, crackers/bread etc. A few nice ales to drink.
We change it up on the roast depending on what we fancy each year - our favourite is goose (this is also the easiest thing to cook - it’s so fatty you can just put it in, leave it, and it’s basically impossible to overcook, although that isn’t an issue now that we have a really good meat thermometer).
We always prep what we can ahead of time, preferably the day before, we cook or heat up most of the veg and accompaniments on the hob and in the microwave, leaving the oven free for the bird, and once the bird is done and resting, the roast potatoes, one tray of parsnips and carrots, the pigs in blankets and the stuffing. We buy our gravy and the red cabbage pre-made from M&S. Sprouts are easily done (I keep it very simple - either plain or fried with pancetta). We have found after years of trying various fancy abc time consuming stuffings that we all like the dried sage and onion best, so that’s what we have. We just get a finest or fancy version.
I buy a pudding - usually the standard mandarin trifle from M&S, but we have also done more fancy things in the past including an expensive creation by Heston Blumenthal which tasted horrible and definitely wasn’t worth the price tag. My OH is the only one who eats Christmas pudding and/or cake so we get him a little one.
I absolutely won’t slave away in the kitchen at Christmas. That’s not what makes a lovely Christmas for me (but I can completely understand why you felt compelled to try to make it perfect last year).
I think it’s really important that everyone gets to chill and relax. My OH and I cook together.
We never, ever stress over having a set time for the meal. We just eat when it’s ready. That cuts down a lot of the pressure.
