How to Store Fresh Herbs So They Last Weeks, Not Days

We’ve all done it: bought a beautiful bunch of coriander on Saturday, and by Tuesday it’s a black, slimy tragedy at the bottom of the fridge. Fresh herbs are one of the most wasted foods in UK kitchens — and one of the easiest to save. Here’s how to store fresh herbs so they last longer, with methods for every type, from delicate basil to woody rosemary.

First: understand your herbs

Herbs fall into two camps, and they need opposite treatment:

• Soft herbs (coriander, parsley, dill, mint, basil, tarragon): high water content, wilt and rot fast. Treat like fresh flowers.
• Woody herbs (rosemary, thyme, sage, oregano, bay): low moisture, sturdy. They dry out rather than rot, and they’re far more forgiving.

Method 1: The jar of water (best for soft herbs)

This is the single most effective trick. Trim the stems, stand the bunch in a jar with an inch of water (like flowers), loosely cover with a plastic bag or a damp tea towel, and refrigerate. Change the water every couple of days. Coriander, parsley and mint stored this way easily last 2-3 weeks — I’ve had parsley go a full month. It’s absurdly simple and it works better than every gadget I’ve tried.

Method 2: The damp towel roll (great for all soft herbs)

Wash and thoroughly dry the herbs (a salad spinner is ideal — excess water causes rot), lay them on a slightly damp tea towel or kitchen paper, roll it up loosely, and pop the roll in a sealed bag or container in the fridge. The towel maintains humidity without sogginess. Lasts 10-14 days for most soft herbs. This is my default for dill and tarragon, which are too delicate for the jar method.

Method 3: The basil exception

Basil hates the cold — refrigeration turns it black. Keep basil like cut flowers on the countertop, stems in water, at room temperature, away from direct sun. It’ll last a week or more this way. Only refrigerate basil if you must, and expect some darkening. Better yet, if you buy basil regularly, keep a living plant on the windowsill — supermarkets sell them for £1-£2 and they last months with watering.

Method 4: Freeze them (best long-term option)

For herbs you cook with (rather than garnish with), freezing is brilliant:

• Chop and freeze in oil: Pack chopped herbs into ice cube trays, cover with olive oil, freeze. Pop a cube straight into a hot pan — instant flavour base.
• Freeze whole on a tray: Spread rosemary, thyme or sage sprigs on a baking tray, freeze, then bag. They crumble perfectly from frozen.
• Herb butter: Mix chopped herbs into softened butter, roll into a log in cling film, freeze and slice. Fancy restaurant trick, zero effort.

Frozen herbs lose their fresh-garnish looks but keep their flavour for 3-6 months. Don’t freeze delicate herbs you plan to use raw — they go limp on thawing.

Method 5: Dry woody herbs

Rosemary, thyme, oregano and sage dry beautifully. Tie in small bunches and hang upside down in a dry, airy spot out of direct sun for 1-2 weeks, then crumble into jars. Or use the oven: lowest setting, door ajar, 1-2 hours. Home-dried herbs beat shop-bought dried ones by a mile — and it’s deeply satisfying.

What NOT to do

• Don’t store herbs wet in a sealed bag. That’s the slime fast-track. Dry them first, always.
• Don’t keep them in the supermarket packaging. Those plastic sleeves trap moisture and ethylene. Unpack them the day you buy.
• Don’t put basil in the fridge. Worth repeating — cold kills it.
• Don’t buy more than you need. The best storage method is not overbuying. Plan your week’s cooking around one or two bunches.

The money angle

A bunch of fresh herbs costs £1-£1.50. Throw away half your herbs each week and that’s £25-£40 a year in the bin — before counting the extra shops. It’s a small part of the bigger picture: learning how to reduce food waste at home in the UK starts with exactly these unglamorous habits. The jar-of-water trick costs nothing and saves real money over a year.

It’s also worth noting that properly stored herbs improve everything else you cook — including energy-efficient cooking. If you’re weighing up whether air fryers are cheaper to run than ovens, fresh herbs make the cheaper option taste like the expensive one.

The Love Food Hate Waste campaign has excellent UK-specific guidance on storing all fresh produce, not just herbs.

Quick reference

• Coriander/parsley/mint: jar of water in fridge, 2-3 weeks
• Dill/tarragon: damp towel roll in fridge, 10-14 days
• Basil: jar of water on counter, NOT fridge, ~1 week
• Rosemary/thyme/sage: dry or freeze, months
• For cooking: freeze in oil cubes, 3-6 months

How to store fresh herbs so they last longer: the weekly routine

Knowing the methods is one thing; building the habit is another. Here’s the routine that actually works in a real kitchen. Shopping day: unpack herbs immediately — don’t leave them in the bag “for later.” Later never comes, and the bag is where herbs go to die. Wash, spin dry, and set up: soft herbs in jars of water in the fridge, basil in a jar on the counter, woody herbs in the crisper drawer as-is.

Midweek check (2 minutes): change the water in the jars, pinch off any leaves that are turning, and assess what’s left. This tiny bit of maintenance doubles the lifespan — the one slimy leaf is what starts the rot cascade, so removing it early saves the bunch. If a bunch is fading faster than you’ll use it, chop and freeze it in oil right then. Future you, mid-recipe, will be grateful.

End of week: anything still hanging on becomes pesto, herb butter, or goes into a use-it-up meal. Soft herbs past their garnish prime are still perfect blitzed into sauces — a handful of tired coriander becomes a great chutney, wilting parsley becomes gremolata. The goal isn’t zero waste through perfection; it’s a system where the default outcome is “used” rather than “binned.” Once the jar-of-water habit is automatic, you’ll wonder why you ever accepted three-day herbs.

The takeaway

Jar of water in the fridge for soft herbs, countertop for basil, dry or freeze the woody ones — and always dry before storing. These three habits will take your herbs from a 3-day lifespan to 2-3 weeks, save you money, and mean you’ve always got fresh flavour to hand when dinner needs it.
