1-Preheat the oven: Preheat the oven to 425°F and line a rimmed baking sheet with parchment paper, then coat it with olive oil spray for easy cleanup.

2-Slice the zucchini: Slice the 2 medium zucchini into ⅛-inch-thick rounds to ensure uniform crisping.

3-Salt the slices: Sprinkle the slices with ½ teaspoon of the kosher salt and let them sit in a colander for 30 minutes to remove excess water, then rinse and pat dry with paper towels.

4-Arrange and oil the slices: Arrange the slices in a single layer on the prepared baking sheet and spray them lightly with olive oil.

5-Initial bake and season: Bake for 15 minutes, then remove from the oven and sprinkle with the remaining ¼ teaspoon kosher salt, ½ teaspoon garlic powder, ¼ teaspoon black pepper, and ¼ cup finely grated Parmesan cheese.

6-Final bake: Return to the oven and bake for an additional 15-20 minutes, or until the slices are browned and crispy.

7-Serve: Serve immediately for the best texture and flavor.
