Make your own "sun dried" tomatoes at home with a dehydrator and enjoy them any time of year in so many recipes.

Right next to our gorgeous chili peppers we grew in the garden this year, we also grew a SLEW of just-as-gorgeous tomatoes. We grow them every year, but this year we picked up some fabulous heirloom tomato plants during a visit to Asheville, NC, and gave them a try. Talk about flavor.
Heirlooms are BY FAR my favorite types of tomatoes, and luckily there is a large variety to choose from. Weirdly, they produced quite late in our season, so we had to pick a number of green tomatoes off the plants just before frost struck us. We had a large batch, but let them sit on the kitchen counter with apples to help them ripen. And ripen they did! Neat trick, the apples.
If you bury an apple in your tomato bowl, it will speed along the process. And you want to cut the tomatoes off the plant so you are not severing the stem from the tomato. This helps them last longer which is needed for the ripening process.
So, the question remains. What to do with all these tomatoes? We've made plenty of sauces and froze a lot, but another way to consider preserving your outstanding tomato harvest is to make sun dried tomatoes at home. But wait? It isn't very sunny! And it's cold outside! How can we do this?
You do this, my friends, with a dehydrator. I've posted information on how to dehydrate chili peppers, and the same principal works for tomatoes. The process is simple. First, you need a dehydrator.
Here is a link to the one I own - It's an affiliate link, FYI: Nesco Snackmaster Pro Food Dehydrator FD-75A. I LOVE this dehydrator. AND! You need some tomatoes, olive oil, and a few other ingredients. The recipe is listed below, but here are some photos to help you out.
How to Make Sun Dried Tomatoes (in a Dehydrator)
First things first. Clean and dry your tomatoes, then slice them into fairly thin slices, about a quarter inch thick or less. Some recipes call for coring them out, even peeling them, blanching them first, but we don't think so. We're making it easy, and to be honest, the resulting tomatoes come out great this way. Try it. You'll see.

Lay out your tomatoes like so. Give them room to dry. Sprinkle the tomatoes with a bit of salt, pepper, dried basil and/or dried oregano. Cover, and turn on the dehydrator. You'll want a temperature of 140 degrees, the same for dehydrating chili peppers.
A difference here, though, is that you don't necessarily want your tomatoes to dry out completely. You want them to be somewhat pliable, so keep your dehydrating time at about 6-8 hours. You'll need to check on them to make sure they are dried out enough, but not TOO dry.
Ours were done at the 6 hour mark, but again, be sure to keep an eye on them after about 6 hours or so. If you flip them half way through it will help prevent them from sticking to the dehydrator tray. Plus it allows you to season the other side if you'd like more seasoning.
Once dried, remove them and layer them in a jar with fresh basil leaves, rosemary sprigs, and a bit more salt, pepper, dried basil and dried oregano. Like so.

Once you've got your tomatoes nicely layered, cover them in olive oil. You can press down on the tomatoes and contents of the jar to compress them, making room for more tomatoes. Just be sure the ingredients are all submerged in oil.
Just like this...

Doesn't it look delicious? Oh yes! Cover tightly with a lid and refrigerate. They should last 4 days this way in the refrigerator, or several months in the freezer. Perfect for so many recipes!

Hey, Mike! Thanks for your inspiration...again!. We have an older model Nesco from a friend, and with lots of tomatoes, went to work! Took about ten, with the suggested seasonings, flipped them after three hours, did four hours second side and voila! packed them in the jar with my basil and oregano, and they'll be the kick-butt addition to my scrambled egg, sauteed mushroom and onion dinner tonight! Hmmm...what wine to pair it with??
Mike Hultquist says
Yes, wonderful!! I'd love to hear what wine you picked! Enjoy!
Lorna says
Thanks for this. I was wondering if I dried them and then stored them like any other dried fruit/vegetable, but rehydrated them in oil with the fresh herbs as you suggested, but only when ready to use would they last all year?
Mike Hultquist says
Lorna, yes, if you dehydrate them, they will last all year (and even longer). Then you can use them in oil later on. Great way to use them. Enjoy!
Holly Marrow says
Thanks for the recipe! I made a big batch last year and when they were cool, I put them in zip-lock freezer bags and sucked all the air out. They last for months this way! I add them to sauces, pizza, omelets etc. throughout the year.
Mike Hultquist says
Yes!! Glad to be helpful, Holly! Very happy you're enjoying them!
