Oven Dried Strawberries

Last year I dried some apples in the oven and they turned out nice. I use dried fruit in granola and thought I would try some strawberries this time, as I had quite a few. I really need a dehydrator though- it took way too long in the oven.
I found a good article on dehydrating fruits and veggies. I cut the strawberries to about 1/4" think and laid them on parchment paper which I had directly on the oven rack. I set the oven to 170 degrees (because that's the lowest it will go) and stuck a wooden spoon in the door to hold it slightly open.
Some of the strawberries dried faster than others- it depended on how thick they were. But the were all done after about 5 hours. I ended up with enough for one batch of granola- so not really worth it for me, but I had to try. I did turn them over once so they could dry on both sides. It was a time consuming job.
