• Fresh rosemary sprigs

How to Make Rosemary Powder

Step 1

Start with about eight fresh rosemary sprigs. Rinse them thoroughly in cold water to remove dirt or residue, especially if homegrown. Pat completely dry using a kitchen towel—this is crucial, as moisture interferes with drying.

Strip the leaves from the stems by holding the tip of the sprig and sliding your fingers downward against the direction of growth. The needles should come off easily. Discard the woody stems.

Place the rosemary leaves between two sheets of parchment paper and microwave for about 2 minutes, checking halfway to ensure they dry evenly without burning.

Step 2

The leaves are ready when they feel crisp and snap easily. Transfer them to a spice grinder, blender, or food processor. Pulse in short bursts until you achieve a fine powder. For a smoother texture, sift through a fine mesh strainer to remove coarse bits.

Step 3

Pour the rosemary powder into a clean, airtight jar. Label it if desired. Store in a cool, dark place and enjoy adding an herbal boost to your cooking anytime.
