Rosemary is a fragrant herb with woody stems that is commonly used in cooking. It is native to the Mediterranean region and has been used for centuries for both its culinary and medicinal properties. Drying rosemary is a great way to preserve its flavor and aroma for use throughout the year. Let's discuss how to dry rosemary at home in a few different ways!
What is Rosemary?
Rosemary (Rosmarinus officinalis) is an evergreen herb that belongs to the mint family. It is native to the Mediterranean region but is now widely cultivated and used throughout the world for culinary, medicinal, and decorative purposes. The plant has fragrant, needle-like leaves and small, blue-purple flowers that bloom in the spring and summer. Rosemary is a popular herb in cooking, particularly in Mediterranean cuisine, where it is used to flavor meats, stews, soups, and sauces. It is also known for its numerous health benefits, such as improving memory, reducing inflammation, and promoting digestion.
Why Dry Rosemary?
Drying rosemary is a great way to preserve its flavor and aroma. Fresh rosemary has a higher water content, which can dilute its essential oils and affect its flavor. Dried rosemary, on the other hand, has a concentrated flavor and aroma. It can be used in a variety of dishes, including soups, stews, marinades, and rubs. Dried rosemary is also easier to store than fresh rosemary, as it takes up less space and has a longer shelf life. And, it's also one of the easiest herbs to dry.
How to Harvest Rosemary
Before drying rosemary, you need to harvest it. The best time to harvest rosemary is in the early morning after the dew has evaporated, but before the sun is too hot. You can either harvest the entire plant or just the branches you need. When harvesting, use clean, sharp scissors or pruning shears to cut the branches near the base of the plant. Avoid pulling the branches off the plant, as this can damage the plant and reduce its yield.
Preparing Rosemary for Drying
Once you have harvested the rosemary, you need to prepare it for drying. Start by removing any dead or damaged leaves from the branches. Rinse the branches under cool running water to remove any dirt or insects. Shake off the excess water and pat the branches dry with a clean towel. A salad spinner also works well for removing excess water.
Next, you need to decide whether to dry fresh rosemary leaves on the stem or remove them. Drying the rosemary leaves on the stem will preserve the flavor and aroma for longer, but it can take longer to dry. Removing the leaves from the stem will allow them to dry faster, but the flavor and aroma may not be as strong. If you choose to dry the rosemary leaves on the stem, tie the branches together with twine or string and hang them upside down in a warm, dry, and well-ventilated area.
If you choose to remove the leaves from the stem, use your fingers or a small knife to strip the leaves off the branches. Discard the stems and spread the leaves out in a single layer on a clean, dry surface.
How to Air-Dry Rosemary
Air drying is the most traditional method of drying rosemary. It involves hanging the branches upside down in a warm, dry, and well-ventilated area. Here’s how to air-dry rosemary:
- For the first step, tie the fresh rosemary sprigs together with twine or string or use rubber bands. Make sure they are tied tightly so that they don't fall apart as they dry.
- Hang the rosemary branches upside down in a warm, dry, and well-ventilated area. The area should be away from direct sunlight, as this can cause the essential oils in the rosemary to break down.
- Leave the rosemary to dry for several days or until the leaves are dry and brittle. The exact drying time will depend on the temperature and humidity of the area.
- Once the rosemary is dry, remove the leaves from the stem by running your fingers along the stem in the opposite direction of the growth. Discard the stems and store the dried rosemary leaves in an airtight container.
How to Oven-Dry Rosemary
Oven drying is a quicker method of drying rosemary, but it can also result in a loss of flavor and aroma if not done correctly. Here’s how to oven-dry rosemary:
- Preheat the oven to the lowest temperature setting.
- Remove the rosemary leaves from the stem and spread them out in a single layer on a baking sheet lined with parchment paper.
- Place the baking sheet in the oven and leave the door slightly open to allow air to circulate.
- Check the rosemary every 10-15 minutes to ensure that it is not burning. The rosemary leaves should be dry and brittle, but not browned.
- Once the rosemary is dry, remove it from the oven and allow it to cool.
- Store the dried rosemary leaves in an airtight container.
How to Microwave-Dry Rosemary
Microwave drying is the quickest method of drying rosemary, but it can also result in a loss of flavor and aroma if not done correctly. Here’s how to microwave-dry rosemary:
- Remove the rosemary leaves from the stem and spread them out in a single layer on a microwave-safe plate.
- Place the plate in the microwave oven, then microwave the rosemary on high for 1-2 minutes, checking every 30 seconds to ensure that it is not burning.
- Once the rosemary is dry and brittle, remove it from the microwave and allow it to cool.
- Store the dried rosemary leaves in an airtight container.
How to Dry Rosemary in a Dehydrator
Drying rosemary in a food dehydrator is a simple process that can preserve the herb's flavor and aroma for long-term use.
- Start by washing the rosemary leaves and patting them dry with a paper towel. Then, spread the leaves in a single layer on the dehydrator trays, making sure they do not overlap.
- Set the dehydrator to a low temperature, around 95°F (35°C), and allow the rosemary to dry for 2-4 hours.
- Check the leaves periodically to ensure they are drying evenly and remove any that are already dry.
- Once the rosemary is completely dry and brittle, remove it from the dehydrator and allow it to cool before storing it in an airtight container.
Drying Rosemary in an Air Fryer
A quick and easy drying method would be to use the air fryer for dehydrating the rosemary. Visit my guide to drying herbs in the air fryer to learn more.

Storing Dried Rosemary
Proper storage is crucial to preserve the best flavor and aroma of dried rosemary.
To store dried rosemary, transfer the herbs to an airtight container, such as a glass jar or a resealable plastic bag, and keep it in a cool, dry, and dark location.
Avoid storing it in a humid area or near a source of heat, as moisture and heat can cause the herbs to lose their potency and flavor.
When properly stored, dried rosemary can last for up to a year or more, making it a convenient and versatile ingredient to have on hand for cooking, seasoning, and herbal remedies.
Using Dried Rosemary
- To use dried rosemary as a culinary herb, simply crumble the leaves between your fingers to release the aromatic oils, before sprinkling them over a dish. Home-dried rosemary beats the stuff you get at the grocery store and it's an excellent herb to keep on hand in a spice cabinet.
- Rosemary can also be infused into oil or vinegar to make a flavorful dressing or marinade.
- Dried rosemary can also be added to baked goods, such as bread, focaccia, and crackers, or used to season roasted vegetables or potatoes, and even made into a rosemary finishing salt.
- Additionally, it can be used in homemade skincare and bath products, such as soaps, scrubs, and bath truffles, for its antioxidant and anti-inflammatory properties.
Drying rosemary is a great way to preserve its flavor and aroma for use throughout the year. Air-drying, oven-drying, microwave-drying, and air-fryer-drying, are four methods of drying rosemary that you can use at home.
The best method for you will depend on the equipment you have available, the amount of rosemary you want to dry, and the time you have available.
Regardless of the method you choose, make sure that you harvest the rosemary at the right time and follow the proper steps to prepare it for drying. With a little bit of effort, you can enjoy the flavor and aroma of dried rosemary in your favorite dishes all year round.
