How to Dry Herbs: Easy Methods That Keep Flavor

If you’re wondering how to dry herbs in the easiest way possible, the answer is simpler than most make it seem. You'll want to try and harvest mid-morning, when flavors are at their best. You can hang woody herbs like rosemary, thyme, and oregano in small bundles somewhere dry and away from direct sunlight  for 1 to 2 weeks. Tender herbs like basil and mint do better laying flat on a screen or in a dehydrator at 95 to 115°F.

Once the leaves easily crumble between your fingers, move them into airtight glass jars away from light, where they’ll hold their flavor for 1 to 3 years. That’s really all there is to it, and the rest of this guide fills in the details.

Fall is the perfect time to do this, whether your first frost hit in late September in northern regions, or won’t show up until mid-November in the south. Your herbs gave you a whole season of flavor. Here’s how to keep that going until spring.

The Best Herbs for Drying 

Woody, low-moisture herbs are a great choice. Rosemary barely loses any flavor as it dries, and oregano often tastes stronger dried than fresh. 

Tender herbs are another story. Cilantro and chives lose most of their flavor when dried, so chop those up and freeze them instead.

When to Harvest Herbs for Drying

Pick between about 9 and 11 AM, once the dew has dried but before the afternoon heat. That's when essential oils (this is what that makes herbs taste like herbs) are at their peak.

Timing matters seasonally too. Most herbs taste best just as flower buds form, and before they open.

• Take no more than one third of a perennial plant at a time.
• Before your area's first fall frost, cut annuals like basil right down. That last harvest is often your biggest batch.
• Skip any yellowed or damaged leaves. Drying won't fix them.

Rinse only if the leaves need it, then pat them dry and let them sit 30 to 60 minutes. Here's what actually happens if you skip that step: damp bundles grow some fuzz in the middle within a few days.

Garden Tip: Growing in a 30" standing bed helps here. Your herbs sit at waist height for easy harvesting. 

How to Dry Herbs: 4 Methods, From Easiest to Fastest

1. Air Drying (Hanging Bundles)

This is the classic method, and it needs nothing but string. It works best for rosemary, thyme, oregano, sage, and lavender. It's especially easy in dry regions. Gardeners in more humid regions along the coast, usually have better luck with a dehydrator.

1. Gather 5 to 7 stems per bundle. Bigger bundles trap moisture.
2. Tie them with a rubber band, which tightens as the stems shrink.
3. Hang them upside down somewhere dark and airy, between 60 and 80°F with humidity under 60%.
4. Keep bundles from touching each other or the wall.
5. Check every few days. Most finish in 1 to 2 weeks.

Keep them out of the sun. A sunny window looks charming but bleaches the color and the flavor right out.

2. Screen Drying

Lay individual leaves or flowers in a single layer on a clean window screen or a cooling rack lined with cheesecloth. Flip them daily. Basil, mint, and chamomile usually take 3 to 7 days to dry.

3. Dehydrator

This is the most reliable option, especially in humid climates where air drying invites mold. Set it around 95 to 115°F and spread herbs in one layer. Start checking after 1 hour for tender herbs, or 3 to 4 hours for woody ones.

4. Oven (In a Pinch)

Use the lowest heat setting, and check every 30 minutes; it usually takes 2 to 4 hours. Expect some flavor loss. A microwave works for a tablespoon in an emergency, but the results will vary.

How to Tell When Herbs Are Fully Dry

Properly dried herbs hold roughly 10% moisture or less. Run three quick checks:

1. Crumble test: leaves break apart easily between your fingers.
2. Snap test: stems snap cleanly instead of bending.
3. Jar test: seal a pinch in a jar overnight. Any condensation means they need more time.

Storing Dried Herbs So They Keep Their Flavor

Light, air, and moisture are the enemies. Store herbs in small glass jars with tight lids, in a cool, dark cabinet that isn't above the stove. Small jars beat one big one, since every opening lets in fresh humidity.

Common misconception: a lot of people crumble everything into powder right away. Store leaves whole and crush them as you cook. Ground herbs fade in 6 to 12 months, while whole ones last much longer:

• Woody herbs (rosemary, thyme, oregano): 2 to 3 years
• Tender herbs (basil, parsley, mint): 1 to 2 years
• Flowers (lavender, chamomile): 1 to 2 years

Label every jar with the herb, the variety, and the harvest date. Trust us, in February every jar of green flakes looks the same.

Drying Herbs FAQ

Can I dry herbs in the sun? We wouldn't. Direct sun breaks down chlorophyll and essential oils, so you end up with brown leaves that taste like hay. A dark space or pantry does a far better job.

How much dried herb equals fresh? Start with 1 teaspoon dried for every tablespoon fresh. Oregano and thyme get stronger as they dry, so go a little lighter with those; parsley usually needs a bit more.

Why did my dried basil turn black? Usually it's too much heat or bruised leaves. Basil is the drama queen of the herb world, so handle it gently and keep your dehydrator closer to 95°F than 115°F.

Which raised bed is best for growing herbs to dry? If you'd like herbs next to tomatoes or carrots, stick with our optimal 12" depth. Lengths run from 18" to 72", you can mix and match so we're sure you'll find something you for every outdoor space.
