Basil, oregano, sage, mints. These are but examples of herbs with high moisture content, which makes them prone to molding if not used quickly. A pass through a dehydrator not only makes them more durable: it also makes them tastier! Here we will be discussing some of the best options to treat your herbs, and useful pointers to choose your own.

What to Know: The Best Dehydrator for Herbs

You should plan to gather them right before the first flowers bloom; the best time of day is in the morning, as soon as the dew has evaporated. Rinse them in cool water and remove excess moisture by shaking them (but not too hard!). Remember to stay away from herbs that have been sprayed with pesticides or other chemicals.

It might save you some time if you preheat your dehydrator while you prepare your herbs. Optimal temperature will range between 90 and 115°F, depending on the moisture present in the air and on the herbs themselves. If you live in an area known for its particularly humid climate, you might have to go as high as 125°F.

 Any leaves that look spotted, bruised, damaged or misshapen should be put aside. You can also remove the longer stems; leaving a little length will save you time, and will help preserve the leaves from damage or bruises. You may take away the whole stem right before storing the leaves.

Your herbs should be laid out in a single layer for dehydration. Employ as many trays as necessary, and remove any that end up empty, so the air can flow through with as little impediment as possible. Be sure to check on their progress every hour; proper dehydration may take anywhere between 1 and 4 hours.

If the batch is rather wet, you might want to begin at the highest temperature and turn the thermostat down gradually; the lower the temperature, the more flavorful the leaves turn out. You will know the batch is ready when the leaves crumble, and the stems break when bent.

The Differences That Count in the Best Dehydrator for Herbs


1. Stackable: This is a great choice if you have little counter space, as their capacity grows upwards and it can go as high as 30”, depending on the model. They also tend to be the most affordable. With these perks, however, comes a drawback: as the fan and heating element are usually at the bottom, the air has to flow through the whole stack of trays, and the one at the lowest position will dry much faster than the tray situated at the top. This means that, for best results, you have to switch trays constantly, so that every part of your batch will dry up evenly.

2. Rigid Box: These are shaped like a toaster oven: square frame, trays within. They can be quite roomy, but they will also require more counter space. Their capacity cannot be expanded, unlike the stackable types, and they are, on average, more expensive.

They do, however, come with advantages: most of the models of this type have the fan and the heat source towards the back, which sends the air flowing across the trays, not from top to bottom; this favors uniform drying for your whole batch without having to constantly switch trays. Rigid box dehydrators are also more versatile: many models can, upon removing some of the trays, assist you in leavening bread, making yoghurt, or dehydrating bulkier foods.

Keep in mind, not only your available counter space, but also how much you plan to dehydrate, before making your final decision.

Temperature Range

This will show remarkable variation between one model and another. Minimum you can expect to find is about 80°F, with the top value being 165°F. Temperature adjustment will vary as well: some units will allow for a 5-degree increment, others will go for as little as a 1-degree interval; some more will have preset settings.


A dehydrator will consume energy through its fan, and its heating element. On average, you can expect one of these appliances to rank between 300 and 1000 watts; size and quantity of fans will also vary between one model and the next. Bear in mind that a more potent dehydrator will also be noisier.

Bonus Features

You can make life a little easier for you if you look for certain extras. For example, a unit with a timer will shut off automatically when done, so you don’t have to worry about your food shriveling up completely. A digital screen will simplify operation for you and your family, and an option with more accessories means you can work with more than just herbs should you so desire. It all comes down to what you would like, as well as your budget.
