  1. Wash and slice the tomatoes into 3/8" slices. You may first 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.
  2. 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.
  3. Turn on your food dehydrator and set the temperature between 125°F and 135°F (or per your food dehydrator's instructions).
  • 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.

When you've finished dehydrating your tomatoes, you'll find they are great to use in many recipes and are excellent for sauces and puréeing.

Try this great tomato sauce by Chef John, over at Allrecipes.

Make them into a powder in your blender and add water to make a paste (or add more water to make a sauce)!

This way, you can store the tomato sauce for use later, maybe as a pizza or as spaghetti sauce!

...and for Making Tasty Tomato Sauce!

When made into a sauce, consider pouring the sauce onto the special roll-up sheets and make a 'tomato roll up/leather.'

Sweet Tomato Soup Memories...

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 just one of those things that you'll always recall. 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.

Consider packing your dehydrated tomatoes in a light extra-virgin olive oil too and add some herbs and garlic to help it along.

You've just created your own version of 'store-bought,' and wasn't it fun?

This just 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!
