How to make homemade sun dried tomatoes

“Place the tray inside your car on the dashboard and cook for 12 hours.”


I had a culinary first for this month’s Recipe ReDux post – I used my car as a cooking vessel.

So, let’s back up.

The Recipe ReDux theme for September is:

Get Your Dehydrator On

Whether it’s extra garden bounty or a sale at the supermarket – dehydrating food is a budget-friendly way to stock up for later. You can use a food dehydrator, a low slow oven, or natural sunshine to preserve natural healthfulness. Show us how you like to dehydrate, or a healthy recipe for how you enjoy using dehydrated fruits, veggies or other bounty.

I don’t have a dehydrator and I knew I could use my oven but I was curious about using the sun instead (they are called sun-dried tomatoes after all) plus I was inspired after Regan told me her Meemaw use to dry crab apples outside every September.

So I did a little more research and came across this article that talked about using your car to speed up the sun drying process.

The timing was right as we had a few hot days on hand, so I prepped the tomatoes (instructions in recipe below), covered the trays with cheesecloth, put them on drying racks and plopped them onto my dashboard (windows up and doors closed.)

Now, this method said it could take two full days and by day 1, the tomatoes were definitely starting to shrink in size. By day 2, there wasn’t too much difference and I quickly realized that the sun/car drying method would be best in DRY HEAT not the crazy humid heat we were experiencing which can kick start the mold growing process.

Not good.

So, in the end, I went back to square one with a new batch and tried the oven method which worked perfectly. About 11 hours later, my “sun-dried” tomatoes were done. I actually had to stop myself from just snacking on them – I saved a few for a sandwich but plan to make another batch soon to use in salads, pizza, pasta and to make pesto.

Most likely I’ll need more than just one batch.

How to Make Sun-Dried Tomatoes

  • Yield: about 2 cups. 1x


It’s super easy to make your own sun-dried tomatoes at home either by way of the sun or your oven. Use this dehydration method for just about any fruit.


  • 5 pounds of small meaty tomatoes like Roma, plum or cherry varieties
  • Few dashes of salt


Sun-Dried Method:

  1. Cut tomatoes in slices (or in half if cherry). It’s optional to remove the seeds.
  2. Place slices on parchment paper on shallow trays, without slices touching each other. Sprinkle with salt.
  3. Place trays on racks and cover with cheesecloth (to protect from bugs.)
  4. Place in hot sun early in the morning (or on your car dashboard if not a humid day.)
  5. This should take a few days – bring the trays in at night. Again, if it’s humid, use the oven method instead.

Oven-Dried Method:

  1. Preheat oven to lowest setting (ideally 150 degrees F.) Prep tomatoes the same way as above and place on trays.
  2. Place trays in oven and keep oven door just slightly ajar to help circulate air (or use the convention oven setting if you have one.)
  3. Check on tomatoes periodically throughout the day – this should take 10 – 12 hours (possibly longer if the tomato slices are large.)

For storage:

  1. Store dried tomatoes in sealed container in refrigerator for up to 3 days.

And here’s how Cooking Light magazine does oven-dried tomatoes (along with 3 other quick ways to cook up tomatoes for extra flavor.)

As a parting photo, I had to share this gem below. Regan & I were too lazy to throw out dehydrated our apple cores over a weekend while we were together for Blog Brûlée.

Looks like you can use this method for all kinds of fruits (though I wouldn’t recommend dehydrating apple cores -ha.)

This is great - I'll have to use the sun next summer, but I appreciate that you included the oven method too!

Love how you tried to dry your tomatoes in the car. I have to say I don't have the patience to wait, although I would love to get a dehydrator one of these days - then I can just set it in a closet and let it do its work.

I was debating about dehydrating tomatoes for this recipe redux but wasn't sure if it would work in the oven. Glad to see that it does! I'll have to try it out before the farmers market runs out of tomatoes. :-)

Ha ha, my husband would kill me if I dried fruit or tomatoes using the car drying method! Anyway, they looked like they turned out great with the oven.
