Slice the zucchini thinly, about ⅛ inch thick. Sprinkle ½ teaspoon of salt on the slices and leave them to drain in a colander for half an hour.

Rinse the slices to remove extra salt. Use paper towels to make sure they’re completely dry.

Put zucchini slices in one layer on the prepared pan, spritz the tops with olive spray, and cook for 15 minutes.

Pull the zucchini out of the oven. Add the rest of the salt, the garlic powder, pepper, and parmesan on top. No need to flip them.

Pop them back in the oven and cook for 15-20 extra minutes until golden and crunchy. Take out any pieces that finish faster.
