On average, each household throws away nearly 30 kg of food per person per year. The kitchen is the room where we waste the most — but also the one where a few good habits change everything.
Cooking zero-waste isn’t about going without: it’s about dosing as precisely as possible, storing intelligently and using what you’d usually throw away. The payoff: real savings and a smaller footprint. Here’s our complete guide.
1. Dose precisely and waste nothing
The first kind of waste is invisible: it’s the ingredients you use too much of. A few simple habits let you dose as close to your needs as possible:
- Weigh your portions of carbs and proteins rather than eyeballing them.
- Dose oil with a spray rather than a pour: you use up to 5 times less.
- Cook the right quantities and plan leftovers for the next day.
- Match your shopping to a weekly menu to avoid wasted purchases.
2. Invest in reusable gear
Disposables are costly and end up in the bin. Replacing a few accessories with durable versions cuts your waste all year round. The maths is quick:
| Use | Disposable solution | Reusable alternative | Benefit |
|---|---|---|---|
| Draining | Fragile colander / film | Clip-on silicone colander | Years of use |
| Covering | Cling film | Lid or beeswax wrap | Zero plastic binned |
| Wiping | Kitchen roll | Washable cloth | Less waste |
| Storing | Disposable bags | Airtight boxes | Protected food |
3. Store well to throw nothing away
A large share of waste comes from food forgotten at the back of the fridge. Organised storage extends freshness and brings forward what needs eating first:
- Apply the “first in, first out” rule: at the front, whatever expires soon.
- Arrange the fridge by temperature zones (coldest for delicate items).
- Store eggs and fragile products visibly and dated.
- Freeze your surplus in portions before it spoils.
💡 Chef’s tip — Keep a clearly visible “eat me first” box in the fridge: put everything nearing its date in it. A single glance is then enough to decide the next meal and avoid waste.
Cooking leftovers and peelings
Zero-waste also plays out on the plate. Carrot tops become a pesto, vegetable peelings a homemade stock, stale bread a delicious French toast. Yesterday’s leftovers turn into a gratin, a soup or an omelette. Cooking “the old way” — throwing nothing away — is often tastier and always more economical.

How do you avoid wasting food?
Store your food well, apply “first in, first out”, freeze surpluses and cook leftovers. Dosing precisely while preparing also limits excess.
Is reusable gear really more economical?
Yes: a durable accessory like a silicone colander or an oil sprayer pays for itself within a few months versus disposables, while cutting your waste for years.
