Tie eight to 10 herb stems together at the bottom of the stems. Hang the bundles upside down in a warm, dry place and let them dry for five to 14 days. The length of drying time will vary depending on humidity and herb type.
Wrap herb bunches in a damp paper towel and keep in an airtight resealable bag in the refrigerator. This method does not work for preserving basil.
Trim the herb stems and place them in a jar or cup with water. Cover the herb tops with a resealable plastic bag and store in the refrigerator. Do not use this method to preserve basil.
Line a microwave safe plate with two layers of paper towels, and spread herb leaves on top. Cover with another paper towel and microwave for one minute on high. If the herbs are not dry, microwave on high in 20-second increments until dry. Timings will vary depending on herb type.
