Set the oven to 425°F. Cover a baking tray with heat-safe parchment paper and lightly coat it with a spray of olive oil.

Slice zucchini rounds at about ⅛-inch thickness. Shake ½ teaspoon kosher salt over them and leave in a colander for half an hour to drain.
03 -
Rinse the salted zucchini slices, then use paper towels to dry them really well.
04 -
Spread zucchini rounds out in one layer on the tray you prepped. Spray lightly with olive oil and bake for 15 minutes.
05 -
Take the tray out, scatter the parmesan, remaining salt, pepper, and garlic powder on the zucchini. No need to flip them over.
06 -
Put the tray back in the oven. Bake for another 15-20 minutes until golden and crispy, taking out pieces as they finish sooner.
