When I was little, we ate a lot of dried apples. At one point we even got a dehydrator to make it easier (I'm pretty sure that was around the time there was an infomercial about them that played repeatedly...). We made all sorts of things for a period of time and it was so much fun to transform regular fruit into its dried version. I never realized that you could do the same thing with an oven—but with the piles of fruit that we have to use up since we don't really have great cold storage for that large of a quantity, I decided to give it a try.
What you see above are the results of my efforts: crunchy, flavorful, and deliciously sweet apple chips. They are 100% apples. I didn't add anything to them because I thought I'd start with the basics. All I did was to slice them thinly using my mandoline, then I placed them on parchment lined baking sheets in a 175 F oven for 4ish hours. If you check them earlier than that you'd get something closer to dried apples. One batch I made went as long as 6 hours and they were still delightfully crispy. (I saw a few recipes that called to leave them in for 10 hours, but that length of time seems unncessary).
I made two sandwich bags full and will probably try to make a few more while we have the apples because I have a feeling that we'll be eating these faster than we can make them!
