Place the slices on a layer of paper towel, then place another layer of paper towel over the top. Press down to remove excess moisture - this will help them crisp up!
Transfer the zucchini to a large baking sheet lined with a silicone mat or parchment paper. Make sure that the slices do not overlap. Give the zucchini a quick spray with olive oil, then lightly season with salt, pepper, and onion powder.
Roast for one hour or until just starting to turn brown.
Remove from the oven and leave on the baking sheet for ten minutes - they will crisp up more as they cool.
