How to Dehydrate Tomatoes

Q: Dehydrate tomatoes in oven?

Yes, you can dehydrate tomatoes in the oven. Here's how: Ingredients : Fresh tomatoes, cored, seeded, and sliced 1⁄4 inch thick Optional: Fresh herbs like oregano, basil, thyme Instructions : Preheat oven to 170°F-200°F. Line baking sheets with parchment paper. Arrange racks to accommodate multiple trays. Wash and slice tomatoes. Spread out slices evenly in a single layer without overlapping on the prepared baking sheets. Optionally, sprinkle thinly sliced fresh herbs over the tomatoes for more flavor. Place trays on oven racks. If possible, prop the door open slightly with the handle of a wooden spoon to allow moisture to escape. Dehydrate tomatoes for 6-8 hours until no moisture remains. Flip slices halfway through. Start checking at 5 hours. Fully-dried tomatoes will be shrunken down, darker red, and leathery. They won't be crunchy or brittle when fully dry. Turn off the oven and allow the tomatoes to cool before handling. Store in airtight food vacuum-sealer bags or Mason jars .

Hey there! You're at the right place to learn how to dehydrate tomatoes...

Tomato Trio: on the vine, in a bowl, and sundried

Whether you grow your own or prefer to buy from grocery stores or roadside vegetable stands, after you've seen how easy it is to create dried tomatoes, you'll wonder why on earth you didn't start sooner!

Just Like Sun Dried!

You'll discover that the taste of delicious sun-dried tomatoes is right at your fingertips!

Consider packing your dehydrated tomatoes in a light extra-virgin olive oil too and add some herbs and garlic to help it along. These taste every bit as good (if not better) as the sun-dried tomatoes you buy in jars at the grocery store!

Suggested herbs to try:

Basil - The classic complement to tomatoes. Its sweet, peppery flavor balances the richness of the oil and sweet tomato flavors. Pairs well with balsamic too.
Oregano - Earthy, zesty oregano is perfect with olive oil and brings out the savory side of rehydrated tomatoes.
Thyme - Offers a woodsy, citrusy aroma that infuses olive oil nicely. It also stands up well to the richness of oil-infused tomatoes.
Rosemary - Rosemary works excellently with fruity olive oils and tastes wonderful when paired with sun-dried tomatoes too.
Parsley - Its fresh flavor is a nice palate cleanser against the richness of the olive oil, and brings a vibrancy to dried tomatoes.

You really can't go wrong blending any combination of classic herbs like garlic, parsley, oregano and fresh peppers too for an oil-and-tomato-dressing bursting with flavors.

Here's How to Dehydrate Tomatoes

Let's get busy learning how to dehydrate tomatoes!

Wash and slice the tomatoes into 3/8" slices. You can dip them into boiling water to make skin removal easier if you wish to skin them. For cherry tomatoes, cut in half - no skinning is required.
Arrange the tomatoes on your food dehydrator trays, making sure the tomato slices don't overlap—or if using the cherry tomato halves, place them cut side up to prevent dripping to the lower trays.
Turn on your food dehydrator and set the temperature between 125°F and 135°F (or per your food dehydrator's instructions).

Use our Fahrenheit to Celsius converter here on our site!

Tomatoes will be leathery or brittle when fully dried.
Drying time for tomatoes: between 5-12 hours.
Please remember to rotate your trays for even drying.

For dehydrating tomatoes in a regular oven, see the FAQs on how to do that at the top of the page!

Sweet Tomato Soup Memories...

As a young girl of eight or nine, I used to walk barefoot down our tree-lined avenue where Mum and Dad's bungalow was, to visit my friend, Gillian, down the road.

I always looked forward to seeing Gillian. Her mum used to serve us hot, delicious tomato soup for lunch!

It's one of those things that I will always remember. It was over 50 years ago... how time flies.

Dehydrated Tomatoes Have a Stronger Taste!

NOTE:

When dehydrating tomatoes, like sun-dried tomatoes, look out for them imparting a stronger 'tomato' taste in your recipes.

As mentioned at the top of the page: Pack your dehydrated tomatoes in a light extra-virgin olive oil too and add some herbs and garlic.

You've just created your own version of store-bought sun-dried tomatoes in oil - and wasn't it a lot of fun? Hey, give away jars of your tomatoes as gifts!

A TIP sent in from "Mj" regarding her dehydrated tomatoes:

I also was wondering if you ever turn tomatoes into powder. I dehydrate whole tomatoes sliced (skins and seeds included) and then put it through my grinder.

I found it is a cheater's way of thickening tomato juice for soup and sauces, and I find that not cooking my juice down to a sauce and just adding a little tomato powder has tenfold the flavor.

Last year for holiday gifts I made friends a jar of "All Michigan Vegetable Soup" and the big question from everyone was "Where did the awesome tomato flavor come from?" — I told them it was my little secret!
