Best Herb Dehydrators for Drying Herbs at Home

Part of great cooking is using herbs to accentuate flavors in meats, pastas, vegetables and soups. Many home chefs have a gardens filled with a variety of fresh herbs. Dehydrating herbs preserves the harvest. Whether you have grown too much to use right now or need to collect everything before winter’s frost takes control, dehydrating herbs gives you a supply of flavorful herbs to use and share with others.

The history of herb dehydrating is simple: people needed to preserve all fresh cooking ingredients before winter came. In dry climates, hanging herbs upside-down either in windows or even basements easily does this. For those in more humid climates, this task becomes more challenging as the humidity can yield mold and mildew, ruining the harvest.

Even under the best natural conditions for drying harvested herbs, it is a long process. Utilizing food dehydrators takes this task and makes it easily completed within hours in many cases. Finding the best dehydrator for herbs really starts with looking at the overall quantity and frequency you will be dehydrating.

Choosing a Type of Dehydrator

You can find a lot of different “dehydrators” on the market, some even being a simple mesh screen to naturally dehydrate herbs but prevents bug infestation. For the sake of our reviews, we are looking at electric dehydrators that use fans and convection methods to dry the herbs.

The two primary food dehydrators used for herbs are:

  1. Stackable
  2. Box-and-shelf

Stackable Dehydrators: These models are cost efficient and easy to use. Models use a fan at the bottom of the unit that blow air up through stacked trays of herbs. You can customize the number of layers to dehydrate herbs as necessary. Even though these are cost-effective, they are not efficient for large amounts of herb dehydration because you need to constantly rotate tray stacks so the top trays get closer to the heat. If you don’t, the lower trays take all of the hot air and dehydrate faster than the rest, potentially over-drying the leaves in lower layers.

Box-and-Shelf Dehydrators: These models usually cost more but require less attention during the drying process. A central box has layers of trays that pull out in from a front access door. A fan in the back of the unit blows the air across the trays more evenly than the bottom-level fan of stackable units.  This allows all levels to receive the same airflow and dehydrate at the same time. In other words, you don’t need to swap the bottom tray for the top when using box-and-shelf dehydrators.

Process to Dry Herbs in Dehydrator

Having the right herb dehydrator is only part of the equation. Properly preparing the herbs for drying ensures you are maximizing the harvest and more efficiently preparing it for dehydration.

  1. Wash and clean the herbs. Blot leaves dry with a towel to remove any excess moisture that would delay the drying process.
  2. Preheat the dehydrator. Most herbs dehydrate efficiently between 95 and 115 degrees in arid environments though humid areas might require higher temperatures up to 125 degrees.
  3. Remove leaves from stems to make drying faster and later preparation easier.
  4. Lay herbs out in single layers on each tray sheet to make sure enough airflow circulates around the leaves.
  5. Monitor the first few batches or new herb varieties. The more moisture in the herb, the longer it takes to properly dehydrate. Most herbs take anywhere from 1 to 4 hours to dehydrate.
  6. Properly dried herbs will crumble in your fingers when rubbed together.
  7. Cool herbs prior to jarring for storage.

Note: You can dry more than one type of herb in the same batch. Flavors don’t blend or infuse into each other and your final dried herbs will remain fully robust with their own natural, concentrated flavors.

Using Dried Herbs

When cooking with dried herbs, use a fraction of what you would use with fresh herbs. Dehydrated herbs are more concentrated. If a recipe calls for a cup of fresh chopped herbs, substitute it with a third of the fresh amount or 1/3 Cup.

Dried herbs do lose their flavor over time. Store in airtight jars or containers to retain maximum flavor and freshness. Keep away from direct light and excessive heat when storing. Most dried herbs lose potency after 1 to 3 years.

FAQs

  • What makes one dehydrator better than another?

When shopping for a dehydrator, consider what you will be using it for the most. For people looking to dry everything from herbs to meats, a dehydrator with a wide temperature range gives more control over the process.

Someone doing regular, small batch dehydration projects might want a unit with a smaller footprint compared to units that hold larger amounts of food. Someone doing less frequent projects will enjoy a unit that stores easily so it doesn’t take up permanent counter space. Some box-and-shelf units do fold for easier storage making them very convenient for occasional use.

  • Should I use a stackable or box-and-shelf model?

When used correctly, either a stackable or box-and-shelf unit function equally. Keep in mind that rotation and monitoring adjust drying times because the closed heat system is opened for the time it takes to check your items.

Frequent monitor should be reduced after the first few uses as you will understand how the unit words and have a better understanding of timing of dehydrating different herbs, fruits and meats.

  • Do I need a dehydrator specifically for herbs?

No. You don’t need to buy a “herb specific” dehydrator. Most herbs will dehydrate nicely between 95 to 115 degrees Fahrenheit.  This means you will want some temperature flexibility when choosing a dehydrator specifically for herbs.

Remember that the amount of moisture in the herbs will determine how fast they dry. Monitor your first few batches to see what temperature works best for the herb selection you have and for the natural environmental conditions the herbs were grown in. More arid conditions may yield herbs with less natural moisture.

The lower the temperature the longer the process for drying. However, the slower process helps lock in flavor more naturally giving the herbs more concentrated flavor and aroma.

Herbs are always a great addition to any meal, particularly during SHTF. Dehydrating herbs is naturally a fantastic way to preserve them for long term usage. Find out how and the best herb dehydrators here!

  1. Kale is one of the most nutritious foods. I grow it all year and dry it in my Excaliber dehydrator. I wanted to know how much to use each day so I dried 1 tray covered with medium size kale leaves for about 12 hours at 115f, took off the stems, broke it up into a 1 cup measure, put in VitaMix and blended into a powder. The powder measured 4 teaspoons. Can use in Smoothies. Of course, in the future I will use all 9 trays to dry the kale which should give me about 36 teaspoons, and very easy to do, pick, clean, dry and blend. Each person can determine how much to use according to their vitamin/mineral need.
    For soups and salads can blend it into bits to sprinkle it on your food.
