The turkey might take centre stage, but everyone knows the Christmas dinner trimmings are just as important. From perfectly crisp roast potatoes and indulgent cauliflower cheese to sticky glazed vegetables and generous pigs in blankets, the right sides bring the whole meal together. If you would rather spend less time preparing and more time enjoying the day, Britain's supermarkets have some tempting ready-made options for Christmas 2026. Here are 12 of our favourites to inspire your festive feast.
Prices and seasonal availability may change, so please check directly with each supermarket before shopping.
Few things earn their place on a Christmas plate quite like a really good roast potato. Waitrose takes the classic a step further with potatoes dressed in rapeseed oil and Wagyu beef dripping, which melts as they cook to create a golden, crisp exterior and a fluffy middle. An indulgent, ready-prepared option when oven space and preparation time are both at a premium.
For anyone who believes pigs in blankets are the best part of Christmas dinner, Aldi has doubled down. Each pork sausage is wrapped with an entire rasher of oak-smoked dry-cured bacon, giving these festive favourites a particularly generous, savoury finish. They were also named the top pigs in blankets in Good Housekeeping’s 2026 taste test, making them an appealing choice for the Christmas table.
Brussels sprouts might divide opinion, but a rich cheese sauce can bring almost everyone round. Tesco combines shredded sprouts and leeks with extra mature Cheddar, double cream and mustard, before finishing the gratin with breadcrumbs and chives. It is a comforting way to add something green to the plate without sacrificing that all-important Christmas indulgence.
Morrisons has given the familiar pig in blanket a real centre-of-the-table makeover. This giant version is made with a filling of chestnut, apple and thyme stuffing, wrapped in smoked streaky bacon. Slice it at the table to share alongside roast turkey or serve it with a Boxing Day spread for a deliciously different festive trimming.
Cauliflower cheese is a Christmas favourite in plenty of households, and this one is particularly generous with the cheese. Tender florets sit in a sauce made with West Country Cheddar, Emmental and Pecorino, with mozzarella, extra Cheddar, breadcrumbs and parsley on top. It is creamy, comforting and just as welcome beside roast ham on Boxing Day.
A little sweetness goes a long way when balancing a rich festive roast. These colourful Chantenay carrots are supplied with a blossom honey drizzle and a wild-garlic butter preparation, adding a glossy finish and plenty of flavour. Their mix of colours also makes the Christmas table look especially inviting.
Bright, glossy red cabbage gives the roast dinner a welcome sweet-and-sour counterpoint. Waitrose adds orange juice, ruby port, warming spices and a little sherry vinegar, before finishing it with cranberries, orange zest and butter. It looks festive on the table and makes a lovely addition to leftover turkey or ham the following day.
Stuffing need not be tucked away inside the bird. These individual parcels bring classic sage-and-onion flavours to the plate, combined with pork and caramelised red onion marmalade and wrapped in dry-cured streaky bacon. A sprig of rosemary gives them an attractive finishing touch, making them ideal for a more carefully dressed Christmas dinner.
Mashed potato might not be the most traditional of Christmas trimmings, but it is an excellent addition for guests who prefer something soft and comforting. Tesco’s festive take mixes creamy mashed potato with mozzarella, Emmental and extra mature Cheddar for a wonderfully cheesy accompaniment to turkey, beef or a vegetarian main.
There is something wonderfully festive about a tray of glazed root vegetables. Waitrose pairs tender Chantenay carrots and baby parsnips with maple syrup, orange juice, brown sugar and rosemary for a fragrant, slightly sticky finish. It is an easy way to bring colour and sweetness to the table, particularly alongside richer meat dishes and gravy.
A well-made gravy ties the Christmas dinner together. Tesco’s Finest version uses British turkey and chicken stocks, Sauvignon Blanc and a blend of sage, rosemary and thyme to create a rich, savoury sauce. If you would rather spend less time stirring a pan and more time around the table, this is a handy finishing touch to have in reserve.
For those who enjoy a little extra richness with their Christmas lunch, Waitrose combines British Maris Piper potatoes with extra mature Cornish Quartz Cheddar, double cream and salted butter. An additional layer of Cheddar forms a golden crust in the oven, creating a delicious alternative to ordinary mash.
Whether you are hosting the whole family or keeping Christmas lunch a little smaller this year, a few carefully chosen sides can make the meal feel special without adding to the work. Product availability and prices may vary by location and date, so check with the supermarket before planning your shop.
