Wash and thoroughly dry the fresh thyme. Preheat the oven to 170 degrees F.
Then spread out the fresh thyme on a baking sheet. Make sure that the thyme does not touch or over lap.
Then place the baking sheet in the oven and bake for 25-30 minutes until the thyme leaves are dry and crumble easily.
Make sure to check the thyme regularly while it's cooking as you what the thyme dry but not browned from baking. If the thyme is not dry after 30 minutes, continue to bake it in 5 minute intervals until the thyme is dry.
Then place the thyme stems over a bowl and gently crumble the leaves with your fingers so that the thyme leaves fall off of the stems and into the bowl. Continue this process until all the thyme leaves are removed and crumbled.
Then transfer the dried thyme to an airtight container and store in a cool, dry place.
