Shopping and cooking for one without waste

Last checked November 2026. Offers and rules change: confirm with the provider before you rely on them.

Shopping and cooking for one costs less and wastes less when you plan a few meals ahead, buy loose or in smaller amounts, and treat your freezer as a second larder. Most supermarket packs are sized for families, so the skill is in splitting, freezing and using things up.

Plan a little, save a lot

You do not need a rigid timetable. A rough plan for the week is enough.

Look in the fridge, freezer and cupboard first and plan around what needs using.
Choose four or five main meals. Leave a day or two for leftovers, an invitation or a simple supper on toast.
Let ingredients overlap. Half a cabbage can go into a stir-fry on Monday and soup on Thursday. A small chicken gives a roast, a sandwich and a curry.
Write a list and stick to it. A list is the best defence against offers that end up in the bin.
Do not shop hungry.

Buying the right amount

Buy loose. Two carrots, one onion and a single baking potato from the loose trays cost less and waste less than a bag. Greengrocers and market stalls will sell any quantity.
Use the counters. At a butcher, fishmonger or deli counter you can ask for one chop, one fillet or four slices of ham.
Check the unit price before choosing a small pack. Small packs often cost more per 100g. If the food freezes or keeps, the larger pack divided up at home is usually better value; see the price comparison guide.
Be wary of multi-buys. "Three for two" on fresh food only saves money if you can eat or freeze all three.
Lean on tins and frozen food. Frozen vegetables, fruit and fish are nutritious, good value and let you take out exactly the portion you need. Tinned fish, beans, tomatoes and fruit keep for years.
Buy long-life basics. Rice, pasta, oats, lentils, eggs and long-life milk are the backbone of cheap meals for one.

Yellow-sticker reductions

Supermarkets mark down food that is near its date with a reduced-price label, usually yellow. Reductions tend to start small earlier in the day and get deeper towards the evening, with the biggest cuts in the last hour or two before closing. Timing varies by store, so ask a member of staff when your local branch usually does its final reductions.

Look for a dedicated reduced section in the chilled aisle and by the bakery.
Only buy what you will eat that day or can freeze straight away. Most meat, fish, bread and ready meals can be frozen up to and including the "use by" date.
Reduced fresh bread, sliced and frozen, gives you toast for weeks.

Tip: Some supermarkets and cafes sell surplus food cheaply at the end of the day through phone apps, and many areas have a community fridge or pantry open to everyone. Your library or council will know what runs locally.

Understanding date labels

Label	What it means
Use by	About safety. Do not eat, cook or freeze food after this date, even if it looks and smells fine.
Best before	About quality. Food is safe after this date but may be past its best. Use your eyes and nose.

A great deal of good food is thrown away because of confusion between the two. The Food Standards Agency explains both on its website.

Making the freezer work for you

Split family packs on the day you buy them. Wrap chicken pieces, sausages, mince and fish in single portions so you can take out just one.
Freeze bread sliced and toast it straight from frozen.
Freeze milk in its plastic bottle, with a little poured off to allow for expansion, and thaw it in the fridge.
Grate cheese before freezing and use it from frozen for cooking.
Freeze leftovers flat in labelled bags or small tubs. They stack neatly and thaw quickly.
Label everything with what it is and the date. If handwriting on small labels is hard to read, use a thick marker and large letters.
Thaw meat and fish in the fridge and make sure reheated food is piping hot all the way through. Cooked rice should be cooled quickly, kept in the fridge and eaten within a day.

Watch out: Do not refreeze raw meat or fish that has thawed unless you cook it first. If you have any doubt about whether something is safe, throw it away.

Cook once, eat twice (or three times)

Cooking a single portion every night is tiring and uses more energy. It is easier to cook a recipe for four and freeze three portions of stew, soup, curry, bolognese sauce, fish pie or cottage pie. After a few weeks you have your own ready meals at a fraction of the shop price.

A slow cooker or a small air fryer uses less energy than a full-size oven for a single portion. For other ways to cut running costs, see keeping warm for less.
One-pan and tray-bake meals save washing up.
If gripping, lifting or opening things is the difficulty, the right equipment makes a real difference: see jar openers and kitchen aids and easy-pour kettles.

Eating well on your own

It is easy to slip into tea and biscuits when there is nobody else to cook for. Try to keep some protein, such as eggs, fish, beans, cheese or meat, and some fruit or vegetables in most meals, and drink regularly through the day. If your appetite has dropped, you are losing weight without meaning to, or you are finding it hard to shop or cook, talk to your GP or practice nurse.

Lunch clubs and community cafes offer a hot meal and company at low cost, and your local Age UK or council can tell you what is nearby, along with meal-delivery services. If the budget is the worry, the benefits checklist is worth ten minutes: a great deal of Pension Credit goes unclaimed every year.

Other ways to cut the food bill

Use supermarket loyalty prices; see loyalty cards compared.
Check for age-related discount days in supermarket discounts for over-60s.
Try own-brand versions of your regular items, one at a time, and keep the ones you like.
If you order online and struggle to reach the minimum spend, stock up on tins, toiletries and frozen food; see supermarket home delivery.

Common questions

Is it more expensive to shop for one?

It can be, pack for pack, because small sizes often cost more per 100g. Buying loose, splitting larger packs and freezing portions removes most of the difference.

Can I freeze food on its use-by date?

Yes, you can freeze most foods right up to and including the use-by date. Thaw in the fridge and use within 24 hours.

When is the best time to find yellow-sticker bargains?

Usually in the evening, in the last couple of hours before closing, but it differs from shop to shop. Staff will generally tell you if you ask.

What can I do if cooking has become too much?

Batch cooking on a good day, frozen ready meals, meal-delivery services and lunch clubs all help. If preparing food is difficult because of your health, ask your GP or council about an assessment of your needs.
