How to freeze dry basil
A typical batch of basil runs about 20 hours in a home freeze dryer, plus usually no extra dry time. Plan on about 12 months (1 year) of good quality for freeze-dried basil, as long as the food is fully dry, sealed in an airtight container or mylar bag with an oxygen absorber and stored cool and dark. These are typical estimates from the FreezeLog guide, not exact times or a safety limit.
General guidance only. Follow your freeze dryer manufacturer's instructions and current food-safety guidance. These are rough figures, not a promise that any food is safe to store or eat. Actual results depend on your machine, load, packing and storage.

How long does it take to freeze dry basil?
A typical batch of basil runs about 20 hours in a home freeze dryer, plus usually no extra dry time. Your machine and load will differ, so check that the batch is dry before you pack it. Here is how to tell when a batch is done.
How do you store freeze-dried basil?
Crumble or leave whole, then seal in a small airtight jar or mylar pouch away from light. Add a small oxygen absorber if you plan to keep it longer than a month. Small portions mean less exposure each time you open it.
