How to Freeze Dry Herbs:
Freeze drying herbs is one of the simplest and most rewarding ways to use your machine.
When done correctly, herbs retain their color, aroma, and flavor exceptionally well—often far better than traditional drying methods.
Why Herbs Are Different
Herbs behave differently than most other foods.
They are more delicate and contain volatile oils that are easily affected by temperature and handling. Because of this, a slightly different approach is needed to preserve their quality.
A Key Difference: Skip Pre-Freezing
Unlike many other foods, herbs are best loaded fresh.
Pre-freezing can damage their structure and lead to darker color and reduced quality. Starting with fresh, properly prepared herbs produces better results.
Temperature Matters
Herbs benefit from lower drying temperatures.
A setting around 95°F helps preserve color, protect delicate oils, and maintain strong flavor. Higher temperatures may affect quality.
How to Freeze Dry Herbs
The process itself is simple and does not require much adjustment.
Start by rinsing herbs gently to remove dirt or debris. After washing, allow to dry to remove excess surface moisture.
Trim away thicker stems and focus on the usable portions of the plant. Spread herbs lightly across trays, keeping the layer even.
Once the trays are loaded, run the cycle at a lower temperature (95F) and allow the machine to complete the process.
How Long It Takes
Herbs usually dry faster than most other foods.
Many batches finish within 12-24 hours although exact timing depends on the type of herb and how it was prepared.
How to Tell When They’re Done
Finished herbs should feel completely dry and crisp.
If you break a piece, it should snap easily rather than bend. Any softness or cool spots indicate that more drying time is needed.

Storage
Once drying is complete, store herbs in airtight containers as soon as possible.
Keeping them protected from air, light, and moisture helps preserve flavor over time. For long-term storage, sealed systems provide the best results.
