How To Dry Fresh Herbs Using a Dehydrator. 1  Preheat your dehydrator with the thermostat set between 95 and 115 degrees Fahrenheit. 2  If your herbs are damp, be sure to gently blot them dry with a towel to remove as much moisture as you can. 3  Place the herbs on the dehydrator trays in a single layer.
Fresh rosemary is easiest to use because the leaves are soft and pliable. Itâs easy to preserve the flavor of the herb but drying rosemary makes the leaves hard and woody. The process of how to dry rosemary can include grinding the dry needles into powder for use without the hard texture. You can just leave a stem of rosemary on the counter and it will dry, but to ensure safety and quality, a food dehydrator is useful. Dry the stems in a single layer on the dehydrator trays.
