Plan what oven shelves you are going to use for what trays, for how long and at what temp. Turkeys take a lot of space
Plan serving dishes and utensils the day before and put a post it note on each one so you dont forget in the rush
Buy a warming tray thingy to pre warm dishes and plates and then keep things warm once served
Get a load of disposable foil oven trays for the day..less washing up but use them on top of your proper baking trays so they dont wobble when full of food
Start the morning with an empty dishwasher and then run it with all the prep stuff while you are eating, then you will be able to fit the plates in after the meal
Stock up on tin foil, bin bags and kitchen towel (and toilet paper)
Lay the table the night before if possible
Make sure you have containers to put leftovers into, and extra if you want to send leftovers home with anyone
Prep and freeze as much as possible. Generally I am only cooking the turkey from fresh on the day, everything else has been prepped or precooked and frozen before
Lists and timetables are your friend
Dont drink too much until you have finished dealing with anything with hot fat (learned that one the hard way)
Someone who doesnt cook does the clean up
Dont let faffers into the kitchen, they get in the way
Have fun
