Christmas dinner timings, the British way: the 25th hour by hour, the shopping list and Boxing Day

In short

• Turkey cooking time, per the FSA, at 180°C (160°C fan, gas 4): 45 minutes per kg plus 20 minutes under 4.5 kg, 40 minutes per kg from 4.5 to 6.5 kg, 35 minutes per kg above 6.5 kg. Unstuffed, with the stuffing in its own tin.
• A frozen turkey thaws in the fridge at roughly 10 to 12 hours per kg, and the FSA warns a whole bird can take 3 to 5 days. For Christmas 2026, which falls on a Friday, a 5 kg bird goes into the fridge on Sunday 20 December.
• The rest is the secret of the single oven. A large turkey out at 12.50pm, wrapped in foil and tea towels, is still hot to carve at 1.50pm, and the oven goes up to 220°C for the potatoes in the meantime.
• Count about 500 g of oven-ready whole turkey per person, or 300 to 400 g of crown (Which?). For six with Boxing Day sandwiches, 5 kg.
• Leftovers go in the fridge within one to two hours of cooking and get eaten within two days, the FSA says. That covers Boxing Day and the 27th; anything beyond goes in the freezer on the evening of the 26th.

Start from the plates and count backwards

Every Christmas dinner timetable that works is written in reverse. You pick the minute people sit down, then subtract: carving, the rest, the cooking time from the label or the FSA formula, the 30 minutes the bird spends out of the fridge, the time the oven takes to heat. The one number you must have before Christmas Eve is the oven-ready weight of your turkey. Write it at the top of a sheet of paper, because everything else on the sheet is arithmetic.

The second thing to know is that you are not the bottleneck. The oven is. A turkey wants 180°C for hours, roast potatoes want 220°C and the top shelf for nearly an hour, and the stuffing and pigs in blankets want 30 minutes somewhere in between. With one oven, that only works if the turkey comes out a full hour before you eat. With two ovens, or a big air fryer for the pigs in blankets, you buy yourself slack, but the order stays the same.

Count the rings on the hob too. On a normal four-ring hob, the last half hour asks for gravy, sprouts, bread sauce and, if it is homemade, a steaming Christmas pudding all at once. Something has to move: bread sauce reheats perfectly well in the microwave, and that frees the ring you need.

We have built the plan around a 2pm sit-down, which leaves the table cleared before the King’s Christmas message, traditionally broadcast at 3pm. If your family eats at 3pm or 4pm, slide every line down by an hour or two and nothing else changes.

This is the 5 kg version. The left column is the oven, the right one is everything else, including you. Pin it to a cupboard door at eye level.

Christmas Eve prep that changes the 25th

Most of the stress on Christmas morning is jobs that could have been done the day before. These are the ones that genuinely move time off the 25th, in the order we would do them on the afternoon of the 24th.

• Check the turkey has thawed right through: no ice in the cavity, legs that move freely at the joint. Lift out the giblets and keep the neck.
• Put the neck, a carrot, an onion, a bay leaf and some peppercorns in a pan of water and let it bubble gently for a couple of hours. That stock is what turns the 1.20pm gravy into a five-minute job.
• Peel the potatoes, cover them with cold water and park the pan in the fridge. Parsnips and carrots peeled and bagged.
• Trim the sprouts and pull off the tired outer leaves. There is no need to cut a cross in the base.
• Mix the stuffing, press it into a buttered tin or roll it into balls, cover and chill.
• Make the bread sauce from start to finish (milk infused with an onion studded with cloves and a bay leaf, then the crumbs), press clingfilm on the surface and refrigerate. It reheats better than it has any right to.
• Brandy butter takes five minutes: soft butter, icing sugar, brandy to taste. Into a dish, into the fridge.
• Free up the fridge. The FSA suggests moving out anything that does not need chilling, such as unopened soft drinks, to make room for what does. Beer and fizz can live in a cool box by the back door.
• Lay the table, crackers and all, and write your timings out by hand. At 1.20pm someone will ask what they can do; the sheet on the cupboard answers them.

How much to buy per person

These are the figures we cook with for a full British Christmas dinner, with all the trimmings on the plate. The turkey crown line follows the Which? rule of thumb of 300 to 400 g per person; the rest are kitchen numbers rather than official ones, rounded to what the shops actually sell. Roast potatoes are the one item where nobody has ever complained of too many.

What actually goes on a British Christmas dinner

YouGov asked Britons in November 2025 what is on their plate, and the answers are a useful shopping check. Roast potatoes and gravy are close to universal (79 to 81 percent), pigs in blankets, stuffing and Brussels sprouts sit at 68 to 70 percent, parsnips at 62 percent. Turkey is on 57 percent of tables, which means a lot of families do beef, gammon, goose or a nut roast instead. Yorkshire puddings split the country almost exactly in half at 49 percent. Christmas pudding, at 41 percent, is still the most popular dessert, and bread sauce is down to 16 percent, which says more about the other 84 percent than about bread sauce.

In practice that means the veg question (what veg on a Christmas dinner?) has a short answer: sprouts, parsnips and carrots cover almost everyone, with red cabbage or peas for the families that insist. If one guest does not eat meat, plan for them on the shopping list rather than at 1.30pm: a tray of potatoes roasted in oil rather than goose fat, a vegetable gravy, and stuffing made without sausagemeat.

The shopping calendar for Christmas 2026

A Christmas food shopping list is only half the job; the other half is when each thing goes in the trolley. In 2025, with Christmas on a Thursday, Worldpanel by Kantar found that Monday 22 December was the busiest day for grocery sales and Tuesday 23 the day with the most trips. With Christmas on a Friday in 2026, expect that crush to land a day later. Buy everything that keeps well before it, and keep the last shop short.

The Christmas dinner shopping list by aisle, for 6

Built from the quantities above for a 5 kg turkey and all the trimmings. Salt, pepper and oil are assumed; check them on the 12th, not on the 23rd.

What almost everyone forgets

• Milk, and lots of it. Six people drinking tea for two days get through more than a normal week, and most shops are shut on the 25th.
• The meat probe’s battery. You only find out it is dead at 12.50pm, holding a 5 kg turkey.
• Somewhere to rest the turkey. A board big enough, plus the foil and two clean tea towels, decided before the bird comes out.
• Containers for the leftovers. Shallow ones cool faster, which matters for the FSA’s one to two hour rule, and labelled freezer bags stop the January mystery parcels.
• Anyone who eats differently. A vegetarian guest cannot eat potatoes roasted in goose fat or gravy made in the turkey tin, and nobody wants to sort that out at 1.30pm.
• Ice, and somewhere cold for the drinks that does not cost you a fridge shelf.

Christmas dinner for 2

A whole turkey for two people is a week of turkey. The two better routes are a 1 kg crown, which Which? puts at 3 to 4 servings and so leaves Boxing Day sandwiches, or a whole duck of about 2 kg, which is the one we would pick. The FSA cooks duck at 200°C (180°C fan, gas 6) for 45 minutes per kg, so a 2 kg bird needs 90 minutes, and the fat it gives off is what the roast potatoes go in. Keep the rest of that fat in a jar in the fridge: it is the best thing that can happen to bubble and squeak.

The shopping list shrinks to one bag: the duck, 600 g of potatoes, two parsnips, 250 g of sprouts, six pigs in blankets, a small pudding or two individual ones, cream or custard, and a bottle of something nice. One roasting tin and one frying pan do the whole meal, and the washing-up is over before the King starts. If you are planning the rest of the week for two as well, our guide to meal planning for one or two covers the scaling problems that do not go away after Christmas.

• 11.45am. Oven to 200°C (180°C fan, gas 6). Prick the duck skin all over, salt it, sit it on a rack over a roasting tin.
• 12.15pm. Duck in. Potatoes peeled and parboiled while it starts.
• 12.45pm. Spoon the rendered fat into a second tin, add the drained potatoes, both tins back in.
• 1.15pm. Parsnips and pigs in blankets in with the potatoes.
• 1.45pm. Duck out and checked: cooked through, juices clear. It rests 15 minutes under foil while the oven goes up to 220°C to crisp the potatoes. Sprouts into a hot pan, gravy from the duck tin and a stock cube.
• 2.00pm. Dinner for two, with plenty of oven left over for warming plates.

Boxing Day: cold cuts, bubble and squeak, and the 48-hour rule

The FSA’s leftover rules are short. Cool cooked food quickly and get it into the fridge or freezer within one to two hours. Eat leftovers within two days, or freeze them if you know that will not happen. When you reheat, make it steaming hot all the way through, and only reheat once. Anything frozen and then thawed should be eaten within 24 hours and not refrozen. In Christmas terms: the turkey you put away at 2.45pm on the 25th is good for Boxing Day and the 27th, and whatever you will not get through by then goes in the freezer on the evening of the 26th.

It matters more than it sounds. The FSA, quoting Love Food Hate Waste, puts the edible food thrown away in UK homes each year at over 100,000 tonnes of poultry, 96,000 tonnes of carrots and 710,000 tonnes of potatoes. Christmas is when a lot of that happens.

Boxing Day food in most British houses is a table you do not have to cook for: cold turkey and any gammon or ham, the cheeseboard, pickled onions, piccalilli, chutney, crusty bread, the last of the cranberry sauce. The one hot dish worth making is bubble and squeak, named, so the story goes, for the noise it makes in the pan. Roughly crush the leftover roast potatoes with the sprouts, parsnips and carrots, season well, press it into a hot frying pan with butter or that saved duck fat, and leave it alone for five or six minutes until a proper crust forms. Turn it in sections, crust up, and serve with a fried egg and slices of cold turkey.

The carcass goes into the big pan on Boxing Day morning with an onion, a carrot and water to cover. By the evening you have stock for a turkey soup or a curry on the 27th, still inside the two-day window, and a few labelled portions of meat in the freezer for January.

How to plan it all in Olivi

If paper suits you, the Christmas dinner timings sheet (PDF, A4) prints in three pages: page one is blank, with your serving time at the top, an hour-by-hour column to fill in backwards, the menu, the guests and the shopping list by aisle; page two is the turkey dinner for six at 2pm, filled in; page three is a cheat sheet with FSA thawing and roasting times by turkey weight, quantities for 2 to 12 and a one-oven timetable.

In Olivi, ask Olive, the virtual cooking coach, something like “Christmas dinner for 6 on 25 December, turkey, one vegetarian, sitting down at 2pm, as much as possible done on Christmas Eve.” She adds the dishes to your plan, and any of them can be moved to the 24th or the 26th. With the region set to the United Kingdom, recipes show grams, millilitres and °C, and the products carry their British names. Set the servings to 6, or to 2, and every quantity follows.

The shopping list is generated from those dishes and sorted by aisle. Share it with whoever does the fresh shop on the 23rd and you see each item ticked off live, even if they have not installed the app. In a packed supermarket with no signal, shopping mode still works.

Christmas Eve fits neatly into a batch cooking session: stock, stuffing, bread sauce and brandy butter in one run, with the long jobs started first. Your nan’s handwritten pudding recipe can come too, if you scan the paper card. On the day, cooking mode shows one step at a time with its timer, and on the 26th the portions you freeze go into your freezer list, so the turkey curry is not forgotten until March.
