Drying herbs is a fantastic way to preserve their flavor and aroma for use throughout the year. Using a dehydrator offers a fast, efficient, and controlled method compared to air drying or oven drying. But a common question arises: can you dry multiple herbs in a dehydrator simultaneously? The answer is yes, with a few important considerations. Let’s dive deep into how to successfully dry a variety of herbs together.
Understanding the Basics of Herb Dehydration
Before we start mixing herbs in the dehydrator, it’s vital to understand the fundamentals of herb dehydration. The goal is to remove moisture from the herbs quickly enough to prevent mold or bacteria growth, while also preserving their essential oils which contribute to their flavor and fragrance.
Proper airflow and consistent temperature are crucial for successful dehydration. A dehydrator achieves this by circulating warm air around the herbs, gradually drawing out the moisture content. The ideal temperature range for most herbs is between 95°F (35°C) and 135°F (57°C).
Why Dehydration Works
Dehydration inhibits microbial growth by reducing the available water activity. This means that bacteria, yeast, and mold find it difficult to thrive. This preservation method allows you to enjoy the flavors of your garden long after the growing season has ended.
Dehydrated herbs retain a concentrated flavor, meaning you often need less of the dried herb compared to fresh. This makes them a cost-effective and space-saving option for storing herbs.
The Key to Successfully Drying Multiple Herbs Together
Drying different herbs together in a dehydrator is possible, but the success depends on several factors. These include moisture content, drying time, and flavor compatibility.
Moisture Content Matters
Herbs with similar moisture content will generally dry at roughly the same rate. This is crucial for even drying. If you combine herbs with vastly different moisture levels, some might become over-dried and brittle while others remain damp and susceptible to mold.
Herbs like basil and mint have higher moisture content than rosemary or thyme. Grouping herbs with comparable moisture levels will lead to better results.
Drying Time Considerations
As mentioned above, herbs with similar moisture content will likely have similar drying times. Regularly check your herbs throughout the dehydration process. Remove individual herbs as they become fully dried, preventing over-drying of those that are ready sooner.
Dehydration time can vary greatly depending on the type of herb, humidity, and your dehydrator model. It’s always best to err on the side of caution and check frequently.
Flavor Compatibility: A Crucial Consideration
While technically you can dry almost any herb together, flavor compatibility is a key element in whether you should. Consider how the aromas of the herbs might mingle during the dehydration process.
Strongly scented herbs like rosemary and oregano could potentially impact the flavor of more delicate herbs like parsley or chives. If you plan to use the herbs separately, it’s generally best to dry them separately.
However, if you plan to use a blend of herbs together frequently, such as a blend for Italian seasoning, drying them together can actually enhance the overall flavor profile. The flavors meld and deepen during the dehydration process.
Practical Tips for Drying Multiple Herbs Simultaneously
Now that we’ve covered the foundational aspects, let’s delve into some practical tips for effectively drying multiple herbs together in your dehydrator.
Preparation is Paramount
Proper preparation is essential for successful herb dehydration, especially when drying multiple types together.
- Wash and Dry: Thoroughly wash all herbs to remove dirt and debris. Gently pat them dry with a clean towel or use a salad spinner to remove excess water.
- Remove Damaged Leaves: Discard any wilted, discolored, or damaged leaves. These can affect the overall quality of the dried herbs.
- Single Layer Placement: Arrange the herbs in a single layer on the dehydrator trays, ensuring that there is adequate space between them for air circulation. Overcrowding the trays will impede the drying process.
- Chopping (Optional): For herbs with large leaves like basil, consider coarsely chopping them. This can speed up the drying process.
Monitoring and Adjusting
Regular monitoring is essential for achieving evenly dried herbs.
- Rotation: Rotate the dehydrator trays periodically (every few hours) to ensure uniform drying. Trays closer to the heat source may dry faster.
- Checking for Doneness: Herbs are dry when they are brittle and crumble easily. Test a few leaves from different herb types to ensure they are adequately dried.
- Removing Dried Herbs: As individual herbs become fully dried, remove them from the dehydrator to prevent over-drying.
- Temperature Adjustment: While the 95-135°F range is generally suitable, you may need to slightly adjust the temperature based on the specific herbs you are drying and your dehydrator’s performance.
Suitable Herb Combinations
Here are some suggested herb combinations that work well together in a dehydrator, based on similar moisture content and complementary flavors:
- Italian Blend: Oregano, rosemary, thyme, and marjoram. These herbs have similar drying times and create a classic Italian seasoning blend.
- Provençal Blend: Thyme, rosemary, savory, and lavender (use sparingly with lavender). This combination evokes the flavors of southern France.
- Mediterranean Blend: Mint, oregano, thyme, and rosemary. This is a refreshing and aromatic blend, great for meat and vegetable dishes.
- Basic Blend: Parsley, chives, and dill. These more delicate herbs can be dried together, but keep a close eye on them, as they might dry faster than others.
Herbs to Dry Separately
Some herbs are best dried separately due to their strong flavors or significantly different drying times.
- Mint: Dries relatively quickly and can overpower other herbs.
- Basil: High moisture content; best dried alone to prevent molding if other herbs are present.
- Garlic: Can impart a strong flavor to other herbs.
- Onion: Similar to garlic, onion should be dried separately.
- Hot Peppers: Due to their potent oils, it is best to dry peppers separately.
Proper Storage of Dehydrated Herbs
Once your herbs are fully dehydrated, proper storage is crucial to maintain their quality and prevent moisture reabsorption.
Cooling Down
Allow the dehydrated herbs to cool completely before storing them. This prevents condensation from forming inside the storage containers.
Airtight Containers
Store the dried herbs in airtight containers, such as glass jars or resealable plastic bags. Ensure the containers are clean and dry.
Dark and Cool Location
Store the containers in a cool, dark, and dry place. Exposure to light and heat can degrade the flavor and aroma of the herbs. A pantry or cupboard away from direct sunlight is ideal.
Labeling
Label each container with the name of the herb and the date it was dried. This helps you keep track of your inventory and use the older herbs first.
Shelf Life
Properly stored dehydrated herbs can last for up to a year or longer. However, their flavor will gradually diminish over time. Check your herbs periodically for any signs of mold or moisture reabsorption. If you notice any issues, discard them.
Troubleshooting Common Issues
Even with careful planning, you might encounter some challenges when drying multiple herbs in a dehydrator. Here are some common issues and how to address them:
Uneven Drying
- Cause: Inconsistent airflow or uneven distribution of herbs on the trays.
- Solution: Rotate the trays regularly and ensure that the herbs are arranged in a single layer with adequate spacing.
Mold Growth
- Cause: Insufficient drying or inadequate airflow.
- Solution: Increase the drying time or temperature. Ensure that the herbs are properly prepared and that the dehydrator is functioning correctly. Discard any herbs that show signs of mold.
Loss of Flavor
- Cause: Over-drying or exposure to heat and light during storage.
- Solution: Monitor the herbs closely during drying and remove them as soon as they are fully dried. Store the dried herbs in airtight containers in a cool, dark location.
Herbs Sticking to Trays
- Cause: High sugar content in some herbs or insufficient pre-treatment.
- Solution: Use dehydrator sheets or parchment paper to prevent sticking. Consider lightly coating the trays with cooking spray.
Conclusion

Can you dry different types of herbs together in a dehydrator?
Yes, you can generally dry different types of herbs together in a dehydrator, but there are a few important considerations to keep in mind. The most crucial factor is ensuring that all herbs require similar drying temperatures and times. Combining herbs with vastly different drying needs can result in some being over-dried and brittle, while others remain damp and susceptible to mold.
Furthermore, consider the aroma profiles of the herbs you plan to dehydrate simultaneously. Strong-smelling herbs, such as rosemary or oregano, can potentially impart their flavor onto more delicate herbs like parsley or mint. If you prefer to maintain the distinct flavors of each herb, it’s best to dry them separately. However, if you’re creating a specific herb blend and don’t mind some flavor mingling, drying them together can be a convenient option.
What temperature is best for drying herbs in a dehydrator?
The optimal temperature for drying herbs in a dehydrator is typically between 95°F (35°C) and 135°F (57°C). This low temperature range helps to preserve the essential oils and flavor compounds within the herbs, resulting in a more potent and flavorful dried product. Using a temperature that is too high can cause the herbs to lose their volatile oils, leading to a loss of flavor and aroma.
It is generally recommended to start at the lower end of this range and gradually increase the temperature if needed. Monitoring the herbs regularly throughout the drying process is crucial to ensure they are drying evenly and not becoming scorched. Consult your dehydrator’s manual for specific temperature recommendations for herbs.
How long does it typically take to dry herbs in a dehydrator?
The drying time for herbs in a dehydrator can vary depending on several factors, including the type of herb, the humidity level in your environment, and the temperature setting of your dehydrator. Generally, it can take anywhere from 2 to 12 hours to completely dry herbs using a dehydrator. Leafy herbs like basil and mint tend to dry faster than herbs with thicker stems like rosemary and thyme.
To determine if your herbs are fully dried, they should feel brittle and easily crumble when touched. If they still feel pliable or have any signs of moisture, continue drying them for a few more hours, checking periodically. Proper drying is essential for preventing mold growth and ensuring the herbs have a long shelf life.
How should I prepare my herbs before drying them in a dehydrator?
Before placing your herbs in the dehydrator, proper preparation is key to ensuring optimal drying and preserving their quality. Begin by thoroughly washing the herbs under cool water to remove any dirt, debris, or insects. Gently pat them dry with a clean towel or use a salad spinner to remove excess water.
Next, remove any damaged or discolored leaves. Depending on the type of herb, you may choose to leave the leaves on the stems or remove them. For herbs like thyme or rosemary, leaving them on the stems can make them easier to handle during the drying process. For herbs like basil or mint, removing the leaves and spreading them in a single layer on the dehydrator trays is often preferred.
How do I know when my herbs are fully dried in the dehydrator?
Determining when your herbs are fully dried is crucial for preventing mold growth and ensuring a long shelf life. The key is to check the texture of the herbs. They should be brittle and easily crumble or snap when touched. Avoid the temptation to stop the dehydration process too early, as residual moisture can lead to spoilage.
To test for dryness, take a few leaves or stems from the dehydrator and allow them to cool completely. Once cooled, try to crumble them between your fingers. If they easily crumble and feel completely dry, they are ready for storage. If they still feel pliable or have any soft spots, continue drying them for a few more hours and retest.
What is the best way to store dehydrated herbs?
The best way to store dehydrated herbs is in airtight containers in a cool, dark, and dry place. Exposure to light, heat, and moisture can degrade the flavor and aroma of the herbs, shortening their shelf life. Glass jars with tight-fitting lids or vacuum-sealed bags are excellent options for storing dehydrated herbs.
Before storing, ensure the herbs have completely cooled down after being removed from the dehydrator. Storing warm herbs can create condensation inside the container, which can lead to mold growth. Label the containers with the date of drying to help you keep track of their freshness. Properly stored dehydrated herbs can typically last for up to a year or longer.
Can I rehydrate dried herbs after they have been dehydrated?
Yes, you can easily rehydrate dried herbs before using them in your cooking. Rehydrating them helps to release their flavor and aroma, making them a more vibrant addition to your dishes. There are a couple of simple methods you can use to rehydrate your dried herbs.
One method is to soak the herbs in a small amount of warm water for about 10-15 minutes. This will soften the herbs and allow them to release their flavor. Another option is to add the dried herbs directly to your cooking liquid, such as broth or sauce, allowing them to rehydrate as the dish simmers. Keep in mind that rehydrated herbs will generally have a softer texture than fresh herbs, but they will still provide a delicious flavor boost to your meals.
