Wash the zucchini, cut off the ends, and slice 1/4-inch thick or 1/8-inch thick for chips. I sliced these 1/4-inch thick today. Use the younger, more tender zucchini when possible. Once they are larger, they have seeds that you will have to remove before dehydrating.

Set your dehydrator at 125 degrees unless your unit states otherwise. Dehydrate until they are brittle. Depending on the humidity where you are dehydrating they may take longer to dry or may take less time.
