Leftover vegetables are often perfectly good and suitable for re-using in new dishes. We will guide you through the dos and don'ts of storing cooked and raw vegetables, help you understand when it is time to toss or keep them, and finally, how to transform those leftovers into delicious meals – all to reduce food waste and get more of your vegetables!
Do's and dont's of storing cooked vegetables
To keep your cooked vegetables fresh, tasty, and safe, it is important to store them properly, whether they are boiled, steamed, baked, or roasted.
Chill cooked vegetables before refrigerating, as cooling helps prevent harmful bacteria that thrive in warmth.
Store cooked vegetables in airtight containers to guard against oxidation and contamination. These containers act like mini fortresses and keep your vegetables fresh. Be cautious not to leave them at room temperature for more than 2 hours to avoid them going bad.
Never freeze vegetables with high water content like lettuce or cucumbers. Freezing turns them soggy or mushy once defrosted. Only freeze these if they are to be used in cooked dishes like casseroles or soups.
Do's and dont's of storing raw vegetables
The key to keeping fresh vegetables vibrant and crisp is understanding how different vegetables react to their surroundings – understanding this, it is easier for you to retain their freshness and flavour.
Store different vegetables separately. Some vegetables (and fruits) like tomatoes and apples emit ethylene gas as they ripen, and these gases can spoil other vegetables. For example, potatoes are sensitive to these gases and can sprout or rot prematurely when exposed to them.
Store vegetables like potatoes, onions, and garlic in a dark, cool, and dry place, but not in the fridge.
Never store raw vegetables in sealed containers or plastic bags. They need proper ventilation to stay fresh; otherwise, they may become slimy and spoil quickly.
Never store potatoes and onions together. The gases they emit can lead to faster spoilage, reducing their shelf life.
Know your vegetables: when to toss and when to keep
Every vegetable has its prime time where it offers a fresh taste before losing its appeal. So when should you keep or toss them?
In general, when vegetables start to blacken, turn mouldy, smell off, or become slimy, you should toss them. But if they simply start to wilt, soften, or the like, they are likely still good to use in sauces, casseroles, and other leftover-friendly dishes.
For example, sturdy root vegetables such as potatoes and carrots can last weeks in or outside the fridge. You can cut off small sprouts and discolourations on the potatoes, and you can revitalise limp or wilted carrots by soaking them in water or using them in soups or casseroles.
Cabbages are quite resilient and can last anywhere from 3 weeks to 2 months in the fridge. You can simply remove limp or discoloured leaves.
Overly soft, wrinkled, or slightly overripe tomatoes can be excellent for sauces or soups. You can store bell peppers in the fridge for up to 2 weeks and use them in cooked dishes if they start to show signs of wrinkling or soft spots.
Turn your leftovers into delicious new dishes
Now, let us talk about the magic of repurposing leftovers. Vegetables are perfectly suited for turning into new dishes either taking centre stage or adding to another dish.
A classic is hash potatoes with different vegetables – for example, celeriac, carrots, and onion. Regular hash served with beetroot and fried eggs are also ideal. In the same way, tarts and quiches let you take various vegetables and turn them into something new and equally delicious. Try, for example, our asparagus quiche encased in a buttery shortcrust and with a velvety egg base topped with thin courgette slices, crunchy toasted pine nuts, fragrant fresh mint leaves, and delicate pea shoots.
For other leftover vegetable mixes, try our warm salad with a base of baked tomatoes and tender fried aubergines, or a grilled courgette salad with a spicy harissa marinade.

Questions about storing and using leftover vegetables
Storing vegetables efficiently and safely is the key to extending their freshness and reducing food waste. So, let us take a deeper dive into these frequently asked questions about vegetable storage to learn more about some essential tips and tricks.
How can you store vegetables to extend their lifetime?
Store most of your vegetables in the fridge, ideally in high-humidity crisper drawers. Avoid washing them before storage, as moisture encourages spoilage. Some vegetables like potatoes and onions prefer cool, dark, well-ventilated places outside the fridge. Others, such as tomatoes, produce ethylene gas and should be stored separately to avoid hastening the ripening process of other vegetables. In this case, tomatoes should be stored at room temperature until ripe to not alter their texture and flavour.
How to store leftover cooked vegetables?
Make sure you cool your leftover vegetables within 2 hours to avoid any bacterial growth. Once cooled, transfer the leftovers to airtight containers or resealable bags and pop them into the fridge. If you store them properly, they can maintain their quality for up to 3-5 days.
How long are leftover vegetables good for?
Leftover cooked vegetables, when cooled and stored in airtight containers or freezer bags, can maintain their quality for up to 3-5 days in the fridge. Do not leave them at room temperature for more than 2 hours to avoid them going bad. Always trust your senses; if the vegetables smell off, have mould, or their texture has significantly changed, discard them.
Can you freeze leftover vegetables?
Yes, you can freeze leftover vegetables. After they cool, place them in airtight containers or freezer bags, removing as much air as possible to prevent freezer burn. Most cooked vegetables can retain their quality for 2-3 months in the freezer, some even up to 8 months. Keep in mind that some may become soft or change texture after freezing.
