Turn the oven on to 425°F. Grab a baking sheet with edges, line it with parchment paper that handles heat well, and give it a coat of olive oil spray.

Cut the zucchini into thin slices about ⅛-inch thick. Scatter ½ teaspoon of kosher salt over them, then set them in a colander to draw water out for 30 minutes.

Rinse off the salt from the zucchini slices. Then, use paper towels to dry them completely.

Lay out the zucchini slices in a single layer on your prepped baking sheet. Spray some olive oil over them and bake for 15 minutes.

Take the baking sheet out of the oven. Sprinkle the zucchini slices with the rest of your salt, black pepper, garlic powder, and parmesan cheese. No flipping needed!

Pop the baking sheet back in the oven for another 15-20 minutes. Keep an eye on them, removing any slices that crisp up faster than others as time goes on.
