How to reduce food waste at home: plan the week and use everything you buy
Food waste rarely happens all at once. It builds up from a bag of salad forgotten in the crisper drawer, half a carton of cream and a sauce you made too much of. Each leftover looks harmless, but over weeks and months they add up to a real amount of food and money going in the bin.
The good news is that most household waste can be prevented before the hob is even on. The most important tool is a weekly plan that starts from what you already have at home.
Where household food waste comes from
The most common causes are surprisingly ordinary. We buy on impulse or just in case, cook bigger portions than we eat and have no plan for leftovers. On top of that, food gets lost at the back of the fridge or a date label is read more strictly than it needs to be. Once you know your own weak spots, you also know where to start.
Start planning at the fridge, not the shop
Before you write a shopping list, open the fridge, freezer and cupboards. Note what needs using soon: an open yoghurt, half a courgette or a bag of spinach. Build the first meals of the week around those, then fill the gaps from the shop. If planning feels like a chore, have a look at our guide to planning the week's dinners in 7 minutes.
Choose recipes that share ingredients
Many ingredients come in bigger packs than one recipe needs. A bunch of coriander, half a leek or the rest of a carton of cream easily ends up in the bin if it has no second use. So plan two dishes in the week that share the same ingredient. Coriander from Monday's tacos works in Wednesday's noodle soup, and sweet potato left over from Tuesday's roast vegetables goes into a breakfast omelette.
Write a shopping list with quantities
A shopping list only works if it includes quantities. A note that just says “carrots” easily turns into a one kilo bag when you needed three. Add up how much of each ingredient the week's recipes need and compare it with what is already at home. Shop on a full stomach and stick to the list. Special offers only pay off if you already know which meal you will use the product in.
Checklist for a low waste week
Check the fridge, freezer and cupboards before you plan a single meal.
Plan the meals that use up perishable ingredients first.
Choose recipes where the same vegetable, herb or sauce appears in two dishes.
Write quantities on your shopping list, not just product names.
Put new shopping at the back of the fridge and older items at the front.
Keep one evening a week for leftovers and clearing out the fridge.
Freeze surplus as soon as you know you will not eat it within a couple of days.
Best before or use by?
Plenty of good food is thrown away needlessly because date labels get mixed up. Under EU food information rules, “best before” marks the date until which a product keeps its best quality. After it, the product can often still be used if it looks, smells and tastes fine and has been stored as instructed. “Use by”, on the other hand, appears on highly perishable foods such as minced meat and fresh fish, and these should not be eaten after the date. So check the label before you throw anything away.
Store food properly and use the oldest first
When you unpack your shopping, move older items to the front of the fridge and put new ones at the back. That way open jars and products close to their date are always the first thing you see. When every food has its own place and temperature, vegetables and herbs keep for longer. You will find more tips in our guide to storing food in the fridge.
Keep one evening for leftovers
One unplanned evening a week is the secret weapon against waste. Gather all the half used items and odds and ends from the fridge and turn them into a meal. Soup is the best base for this, because almost any vegetable works in it. A good example is a coconut sweet potato soup with roasted broccoli, which also welcomes leftover root vegetables. You can find more ideas among our soup recipes. Fried rice, an omelette or a tray of roast vegetables work well too.
Freeze early, not at the last minute
The freezer stops waste when you use it in time. If you can see you will not finish a sauce, bread or cooked meat within a few days, freeze it straight away in portions. Label the bag with the contents and date so you know later what is in the freezer. We cover packing and thawing in more detail in our guide to freezing food properly.
Small changes are enough
Cutting food waste does not require perfection. When you check the fridge before shopping, write a list with quantities and give leftovers their own evening, you will notice the difference within a couple of weeks, both in the bin and in your food budget. A meal kit can lighten the load even further, because the week's recipes are chosen for you and the ingredients arrive portioned for them.
