Wash and dry your tomatoes thoroughly.
Cut you tomatoes thinly. They’ll dehydrate faster that way. I cut mine about 1/4-1/2 inch thickness. I’m not always steady with the knife.
Place the mesh on your trays and then add tomato slices. Don’t let them overlap. You want a single layer.
Set your temperature 135-145F. I did 135F, but will probably do it higher next time because it took longer in my Cosori dehydrator.
Dehydrate for 8-10 hours. If you cut them on the thicker side that time may double.
Let them cool off and then peel them off the mesh. They may stick a bit, turns out tomatoes have quite a bit of sugar in them.
Store in an airtight container or vacuum seal them until you’re ready to use them.
