Sainsbury's has shared a storage hack for leftover fresh herbs: chop them up and add them to an ice cube tray with olive oil. The supermarket says this allows the herbs to be easily added to future dishes instead of being thrown away.
Herb storage hack
Sainsbury's advises: “Instead of letting fresh herbs go bad and throwing them away, chop them up and add them into an ice cube tray with some olive oil. This way, you’ll be able to easily add them into any future dishes you’re making.”
Food waste statistics
According to environmental action body Wrap, the UK sees approximately 6.4 million tonnes of food waste each year. Research from Aldi in 2025 revealed the average Brit throws away food worth roughly £387 annually, while seven in ten Brits admitted to purchasing food knowing it will end up in the bin.
Storage advice for other produce
Sainsbury's has also shared storage guidance for fruits, vegetables, and dairy products to help curb food waste.
Courgettes
Grate courgettes and store in a reusable freezer bag or container. The grated leftovers can be added to omelettes, savoury muffins, fritters, quick breads, or pastas.
Peppers
Slice peppers and freeze them in reusable freezer bags. They can be tossed straight into the pan when cooking stir fries or fajitas.
Raspberries and berries
Berries can be frozen directly in reusable freezer bags or containers to increase shelf life. Frozen berries can be added to smoothies, crumbles, or cakes.
Pineapple
Chop pineapple into bite-sized chunks and freeze portions in reusable bags and containers.
Grapes
Freeze leftover grapes. They can be eaten straight from the freezer as a healthy alternative to sweets or used as a heatwave hack.
Cheese
Grated cheese can be stored in the freezer to prevent mould. Store in a reusable container or freezer bag.
Eggs
Freeze raw eggs by cracking them individually into resealable containers. Yolks and whites can be stored separately.
Yoghurt
Pour leftover yoghurt onto a baking tray lined with non-stick baking paper, scatter leftover fruit on top, and freeze. Once frozen, break into large pieces for healthy yoghurt bark, which can be stored in reusable freezer bags.
