Garden Friday – Sun (Oven) Dried Tomatoes

I left town this week for a 3-week trip to the inlaws.  Of course, just as I was leaving, my tomatoes started to ripen all at once.  What to do?  I didn’t have enough to justify canning yet.  I thought about picking them and putting them in the fridge – but I’m guessing I’ll come home to a lot of tomatoes.  (Note to self, make sure you don’t plan anything on the 2nd day home because you will be canning!)  So I decided to make sun-dried tomatoes from about 2 dozen grape and roma types.

Now, if I had been on top of this, I would have truly sun dried them (or car dried them… good idea for next time) which is far more sustainable with no energy use.  But since it takes about 2 days with the sun (same process, just bring them in at night and cover with cheese-cloth to keep bugs out) and I only had this ‘crap, what am I going to do with these tomatoes?’ moment less than 24 hours before my flight, I decided to take the oven dried shortcut.  (Apparently you can also use a dehydrator, but I don’t own one.)

You can make dried tomatoes from any type, but the more ‘pasty’ romas or cherries are probably easiest and have the least moisture content.  Here are the steps:

1.  Pick tomatoes, wash them, etc.

2. Cut tomatoes into fairly equal parts (they dry more evenly this way).  I cut the small grapes into half, the smaller romas into quarters and the bigger romas into eighths.

3.  Take out a cookie sheet and evenly lay out tomatoes on a piece of parchment paper or foil.  Some people sprinkle with sea salt and/or basil.  I just left them plain.

4. Stick in the oven on lowest setting (I got my convection down to 180 but most recipes seem to state 200 is ok) for 5 to 8 hours.

5. Store in airtight plastic bag.  It seems you can easily get 9 months to a year in your freezer although you hear a lot of people say if you store in a dark, cool food storage room would be fine too.  Some store in olive oil but most warn it should be refrigerated and used within a month or 2 because of botulism concerns.

So, now I have a nice bag of sun-dried tomatoes.  The only question is how to cook with them? (I never purchase them because they are so expensive.)  What is your favorite sun-dried tomato recipe?

    Oh thank you for this, Nicole! My tomatoes are just starting to come on and soon there will be bushels. I plan on canning most but did want to dry some this year (never done it before) so this is VERY helpful!

    Question: you said that botulism is a concern in the olive oil. There’s no concern that you know of with the dried, bagged and stored tomatoes, right?

    Home grown tomatoes are acidic enough to be safe dried. Even if there are a few botulism spores, they can’t really multiple in the acidic tomato. You freeze them mostly to keep mold at bay. Olive oil provides a base for the botulism. In fact, any time you infuse olive oil with anything, you should be putting it in the fridge.

    What do I do with sun dried tomatoes? I might be interested in preserving some this way too.
