But if you spot a food bargain weeks before the big day, is it worth popping it in your basket or will it spoil before you've had the chance to say 'Father Christmas'?
With the help of experts, we tell you what Christmas foods are safe to buy early, and give tips on prepping and storing so they're ready to serve without compromising freshness and flavour.
Eat well, live better and stay healthy.Christmas dishes you can make in advance
Let's be honest - there are more enjoyable Christmas traditions than hitting the kitchen at the crack of dawn to peel and prep, and you shouldn't feel you're 'cheating' if you've done some of it beforehand. Popular chef Tom Kerridge told us: 'It's not cheating at all - it's being prepared. Nobody wants to add to the stress on Christmas Day by having to do everything on the day, so make life easier for yourself with a bit of planning.'Keeping an eye out for food bargains to pop in the freezer and doing the 'boring, time-consuming things' the day before where possible are just two hacks he advises.
Here's how far in advance you can prep, cook and store popular Christmas dinner dishes in the run-up to the big day.
Remember to follow storage and freezing guidance on ready-prepared dishes, such as shop-bought mince pies.
Turkey
Make in advance? How to store:
A Food Standards Agency (FSA) spokesperson told Which?: 'It's possible to cook a whole turkey or turkey crown in advance, freeze and then defrost it for Christmas Day, although slicing the meat, then freezing it means it will take up less freezer space as well as defrosting more quickly.'
Thoroughly defrost in the fridge or on your microwave's defrost setting (never thaw at room temperature), then cook straight away.
When you reheat the turkey, make sure it's piping hot - not just warmed through.
You can also microwave the turkey in slices, in a dish. Cover it with stock or gravy and cook for two minutes on a medium-high setting, before checking it to see if it's piping hot. If not, continue cooking in 30-second bursts.
Don't part-cook a raw turkey before freezing as it could lead to food poisoning. It should be either fully cooked or raw beforehand, and wrapped well to prevent juices getting on to other foods (and to avoid freezer burn to the meat).

Make in advance? How to store:
Parboil peeled, cut potatoes for five minutes, drain then bash them to rough up the sides before drizzling with oil and flash freeze. Also known as open freezing, this is when you freeze smaller food items separately before bagging them so you can take what you need and avoid waste in the process.
After this, you can transfer to an airtight container or sealed bag and cook straight from frozen when needed.

Make in advance?How to store:
Although some people suggest veg can keep for 12 months frozen, three months is optimal for maintaining flavour, texture, colour and nutrient content. This applies whether you're freezing fresh veg or pre-cooked versions such as braised red cabbage, roast parsnips or Brussels with pancetta and chestnuts.

Make in advance? How to store:
Gravy freezes and defrosts well. But unlike fresh gravy, which can be kept in the fridge for two days, defrosted gravy should be used within 24 hours.
A high sugar content is one of the reasons that made-from-scratch cranberry sauce can be kept in the fridge for a couple of weeks.
Frozen bread sauce works best if you add the cream once you've defrosted it.

Make in advance? How to store:
Although you can refrigerate or freeze the separate ingredients, don't prep until you're just about to serve them to give you time to toast the blinis and avoid the crème fraiche making them soggy.
Pigs in blankets
Make in advance? How to store:
You can freeze raw pigs in blankets you've made from uncooked sausages and bacon for up to three months - just flash freeze them first so they don't stick together, and store in an airtight container.
If you want to cook them first, they can be frozen for the same amount of time. However, when you get them out of the freezer to reheat and serve up on Christmas Day, you may find they're at risk of overcooking and drying out.
Shop ahead for the individual ingredients, too, if you spot a bargain. Tom Kerridge says: 'If there is an offer on bacon, get it and freeze it then you can make your own pigs in blankets when the time comes. Little things like that can really help save money.'Christmas pudding
Make in advance?How to store:
Some say it's actually better if you cook and store your Christmas pud in advance - especially if you regularly 'feed' it with brandy or sherry.
In her recipe for Christmas pudding, Mary Berry says you can store your cooked pudding in a cool place for up to three months if it's covered with greaseproof paper and foil, while Nigella Lawson says her pud can be made up to six weeks ahead of Christmas.
