To keep basil fresh and avoid wilting, harvest it carefully before it dries. Also, you should harvest the basil before it flowers for the richest, least bitter flavor. Flowering basil can still be used, so don’t throw it away! Moreover, if you want to promote bushier growth, then regularly trim basil where two leaves surround the stalk.

Step 2: Remove stem and rinse

Gather the basil, then remove the leaves from the stems, throwing the blooms and stems in the compost. To prevent browning, gently wash the leaves in lukewarm water, making sure the temperature is just right. Also, remove or snip leaves so that only the soft sections are left. Use lukewarm water to rinse away any leftover garden or soil residue.

Step 3: Remove excess water

Before beginning the drying process, make sure the basil leaves are totally dry. As in, remove the water from the rinsing you did in the earlier step. So, arrange them on a sanitized kitchen towel in a single layer. Then, gently roll the basil in the towel to ensure that it dries evenly and completely.

While getting rid of extra water, it is important to leave some residual moisture in place and don’t worry too much about it. Next, use a strainer to gently shake the leaves or gently wipe them dry with a dish towel free of dust. Even a salad spinner will do the job!

Here’s how to air dry basil leaves:

  • Gather fresh basil leaves from a reliable source or your own garden. To get rid of any dirt or insects, give the leaves a thorough wash. Gently pat them dry.
  • Lay out the cleaned basil leaves on a rack for drying herbs, or make your own using a mosquito net-covered frame. In order to ensure consistent airflow, it’s important to arrange the leaves in a single layer. It helps in keeping the drying process free of mold and browning.
  • Make sure there is adequate airflow in the drying area. The basil should be kept out of direct sunlight and in a dry area. It will take a few weeks (usually two to four) for the leaves to completely dry, so try to be patient.
  • Although it is recommended to bunch the basil to dry, it works better to make little bunches so that each leaf has enough air to breathe. The drying process may be affected by large bunches that restrict the airflow to the leaves within.
  • Check the basil leaves for dryness on a regular basis. When thoroughly dry, they should crumble. Proceed with the drying process until all leaves are crumbled and dry, even if some still feel wet.

After the basil leaves have dried fully, put them in airtight jars.
