Fresh herbs dying in the fridge within two days is one of cooking’s great frustrations — you buy coriander for a curry, use a third, and find black slime where the rest was. The best way to store fresh herbs so they last longer depends on the herb type, but the universal principles are: treat them like flowers (water, not plastic), keep them cold but not freezing, and manage moisture — too wet rots them, too dry wilts them. Done right, soft herbs last 2–3 weeks instead of 2–3 days.
The two types of herbs (store them differently)
Soft herbs — coriander, parsley, basil, dill, mint, chives. Delicate leaves, high water content, the ones that die fastest. Woody herbs — rosemary, thyme, sage, oregano. Sturdy stems, lower moisture, naturally longer-lived. The storage method differs because their needs differ.
Soft herbs: the bouquet method (best overall)
This is the florist trick, and it’s transformative:
- Trim the stems — cut 1cm off the bottom at an angle, like flowers.
- Stand in a jar with 2–3cm of cold water, stems down, leaves up.
- Cover loosely with a plastic bag or damp tea towel (a mini greenhouse — keeps humidity high without the leaves sitting in water).
- Refrigerate (except basil — see below) and change the water every 2–3 days.
Parsley and coriander kept this way last 2–3 weeks — I’ve had coriander still perky at three weeks. Compare with 2 days in the original plastic sleeve.
Basil is the exception: it hates the cold — fridge temperatures blacken the leaves. Keep basil as a bouquet on the countertop at room temperature, out of direct sun. It’ll last a week or more, and you get a fragrant kitchen as a bonus.
Woody herbs: the damp towel method
Wrap rosemary, thyme, sage and oregano loosely in a damp (not wet) paper towel or tea towel, place in an airtight container or zip-lock bag, and refrigerate. They’ll keep 2–4 weeks easily. The towel maintains humidity while the bag prevents the fridge’s dry air from desiccating them. Check weekly and re-dampen the towel if needed.
The freezer: for long-term storage
When herbs are heading south despite your best efforts, freeze them:
- Chop and freeze in oil: pack chopped herbs into ice cube trays, cover with olive oil, freeze. Pop out cubes straight into hot pans — instant flavour bombs. Brilliant for basil, parsley, coriander, dill.
- Freeze whole on trays: woody herbs (rosemary, thyme) freeze well as whole sprigs — bag once frozen. They go limp when thawed but are perfect for cooking.
- Herb butter: mix chopped herbs into softened butter, roll into a log in cling film, freeze, slice as needed. Garlic-herb butter on steak is worth the effort alone.
Dried herbs are a different product (more concentrated, different flavour) — freezing preserves the fresh taste far better. For general freezing technique, see how to freeze leftovers safely.
Growing your own: the ultimate solution
A £1.50 supermarket “living herb” pot, repotted into a bigger container on a sunny windowsill, produces fresh herbs for months — far cheaper and fresher than cut bunches. Mint, chives, parsley and thyme are nearly indestructible indoors. Basil needs warmth and regular picking (pinch the tops to make it bush out). The RHS herb growing guides cover varieties and care. Even a tiny kitchen windowsill fits three pots — and you’ll never buy a sad plastic sleeve of coriander again.
What NOT to do
- Don’t leave them in the shop packaging — the sealed plastic traps ethylene and moisture: rot accelerator.
- Don’t wash before storing — wash just before use. Stored wet = stored rotting.
- Don’t put basil in the fridge — cold damage blackens it within a day.
- Don’t store near ethylene producers — bananas, tomatoes and onions speed up decay in nearby herbs.
Drying herbs: the traditional method
Freezing preserves fresh flavour best, but drying is the classic for woody herbs — and dried home-grown herbs beat shop-bought dusty jars by miles. Air drying: tie small bunches of rosemary, thyme, oregano or sage with string, hang upside down in a warm, dark, airy spot (an airing cupboard is ideal) for 1–2 weeks until crisp. Dark matters — light bleaches flavour and colour.
Oven drying: lowest oven setting (under 50°C) with the door ajar, 2–4 hours — faster but easier to overdo. Don’t bother drying soft herbs like basil, coriander or parsley by air — they lose too much flavour and go brown; freeze those instead. Once crisp, strip the leaves from stems, store in airtight jars away from light, and label with the date — home-dried herbs are potent for 6–12 months, after which they fade. Crumble a leaf and sniff: if the aroma’s gone, so is the point.
Windowsill herb garden: the setup
Three pots on a sunny windowsill is all it takes. Which herbs: chives (indestructible, regrows after cutting), mint (keep it potted — it invades everything), parsley (biennial — replace yearly), thyme (loves sun, hates wet feet), basil (the diva — warmth, regular water, pinch tops). Pots: 12–15cm with drainage holes; a saucer underneath. Soil: multipurpose compost with added perlite for drainage.
Care basics: water when the top 2cm is dry (not on a schedule — seasons change everything), feed fortnightly in summer with liquid seaweed, and harvest regularly — cutting encourages bushy growth; neglected herbs go leggy and flower (which ends leaf production). Winter: most windowsill herbs sulk from November to February — supplement with shop-bought, and they’ll bounce back in March. A £15 windowsill setup replaces £100+ a year in sad plastic herb sleeves — and the flavour of just-picked herbs ruins shop-bought forever.
The takeaway
Soft herbs: trim, jar of water, loose cover, fridge (basil on the counter). Woody herbs: damp towel, sealed bag, fridge. Excess: chop, freeze in oil cubes. Or grow your own on the windowsill and skip the storage problem entirely. Two minutes of proper storage turns a £1 bunch of coriander from a two-day ingredient into a three-week one — which, across a year of cooking, is real money saved and far less food waste.
