Cutting food waste with smarter meal planning

By Kitchen Prep Ideas Editorial Team · Published 20 October 2026

Practical ways to waste less food and save money: plan meals around what you have, shop with a list, understand use-by and best-before dates, store food well, freeze more and use up leftovers.

UK households throw away millions of tonnes of food each year, much of it still edible, according to the waste charity WRAP. For a typical family that's hundreds of pounds a year. Most waste comes from buying too much, storing food poorly and not using leftovers, all of which better planning can fix.

1. Start with what you have

Before planning, check the fridge, freezer and cupboards.
Plan the first meals of the week around food that needs using up.
Keep a "use first" shelf or box in the fridge.

2. Plan realistic meals

Plan for the nights you'll actually cook. Allow for evenings out and busy days.
Choose recipes that share ingredients, such as using half a bag of spinach in one meal and the rest in another.
Include a flexible "leftovers night" or "fridge-raid" meal each week.
Use portion guides to cook the right amount. Love Food Hate Waste has portion planners for rice and pasta.

3. Shop with a list

Write a list from your plan and stick to it.
Be cautious with multi-buy offers on perishables unless you'll use or freeze them.
Buy loose fruit and vegetables where you can, so you buy only what you need.
Don't shop hungry.

4. Understand date labels

Use by: about safety. Don't eat food after its use-by date, even if it looks and smells fine. You can freeze food up to the use-by date.
Best before: about quality. Food is usually safe after this date but may not be at its best. Use your judgement, except for eggs, which should be eaten by the best-before date.

Many retailers have removed best-before dates from some fresh produce to reduce waste.

5. Store food well

Keep the fridge at 5°C or below; food lasts longer.
Most fruit and vegetables last longer in the fridge, in their packaging. Exceptions include bananas, whole pineapples and onions, which are best kept cool outside the fridge.
Keep bread in a cool, dry place, or freeze it in slices and toast from frozen.
Transfer opened tins to sealed containers in the fridge.

6. Make the most of your freezer

You can freeze far more than many people realise: bread, milk, grated cheese, cooked rice (cooled quickly), bananas for baking, herbs in oil, and most cooked meals. Freeze food in portions, label it with the date, and keep a list on the freezer door.

7. Use up leftovers

Turn vegetables into soups, stir-fries, frittatas or pasta sauces.
Use stale bread for breadcrumbs, croutons or bread pudding.
Blend soft fruit into smoothies or cook it into compote.
Eat cooked leftovers within two days, or freeze them.

A sample week

Buy one large pack of chicken thighs, a bag of carrots and a bag of spinach. Roast the chicken with carrots on Monday; use leftover chicken in wraps with spinach on Tuesday; cook a carrot and lentil soup with the remaining carrots on Wednesday, freezing half; and finish the spinach in a pasta dish on Thursday. Friday is a fridge-raid night.

8. Track what you throw away

For two weeks, note what you bin and why. Patterns, such as salad going limp or bread going mouldy, show where to change shopping or storage.

What to do with unavoidable waste?

Peelings, bones and tea bags can't always be avoided. Use your council's food waste collection where available. In England, councils are being required to collect food waste weekly from households, with most required to start by 31 March 2026. Home composting suits uncooked fruit and vegetable scraps.

Frequently asked questions

Can I refreeze food?

Raw food that has been defrosted and cooked can be frozen again. Don't refreeze defrosted raw food without cooking it first.

Do apps help?

Food-sharing apps let you give away surplus food to neighbours or buy discounted surplus from shops.
