Fascinating, but somewhat anti-climactic.
Suffice it to say, the process was very straightforward. I winged it a bit, but it all seemed to work out. Using what I read from the aforementioned Ball Book and some articles on the internet, I decided to slice the zucchini into 1/4 inch slices. I then lay them on a cookie sheet and set the oven at 175 degrees, which is as low as mine will go.
I also kept the oven door open in order to facilitate the actual dehydrating process, versus cooking. The airflow provided is necessary in order to keep the moisture from recirculating back into the zucchini. If I had a convection oven this might have been an unnecessary step, but sadly I do not have a convection oven and so I simply kept the oven door open about half way.
The whole process took nearly 4 hours and I was obliged to continuously flip the zucchini rounds in order to dry them evenly. If I had a cookie sheet with a rack I probably would not have had to do this step, but again…like the convection oven issue, I didn’t. Regardless, it worked quite well. I did notice however that the pieces that I had cut too thin started to brown and I decided that they were moving too far into the “cooked” spectrum to really qualify as dried. As a result I attempted to add them to burritos for dinner that evening…which was a spectacular failure, I might add.
Regardless, the point of mentioning it was that while some sources might tell you to cut the slices as thin as 1/8 of an inch, if you are using an oven to dry your zucchini I highly suggest to cut things no thinner than 1/4 inch otherwise you may end up with burnt chips.
I will be reattempting the drying routine tomorrow as I still have four zucchini in my fridge, even though I have dried and baked copious amounts and my plants are suffering from an insect invader that is slowly killing them. I do love the abundance of summer squash!
Oven Dried Zucchini
cookie sheets, with racks if possible
Cut the zucchini into 1/4 inch slices, trying to cut them as evenly as possible. Place the slices on the cookie sheet or rack, spacing them relatively close together as they will shrink as the process goes on.
Place in your oven at it’s lowest setting (mine was 175 degrees) and leave the door open at least half way. If your oven door will not remain open half way on its own you may have to rig it. I would not recommend leaving it open all the way and you cannot have it closed altogether either.
Leave in the oven for 4 – 4.5 hours, turning regularly. The zucchini is done when it is no longer flexible. Let cool completely before storing.
