Arrange the zucchini rounds on a towel and sprinkle with 1/2 teaspoon kosher salt. Let them stand for 10 minutes, then pat both sides very dry.

In a shallow bowl, combine panko, Parmesan, mozzarella, Italian seasoning, garlic powder, black pepper, and the remaining 1/4 teaspoon salt.

Dip each zucchini round in beaten egg, letting the excess drip off. Press both sides into the cheese coating and set the rounds on the prepared rack with space between them.

Mist the tops lightly with olive oil spray. Bake for 18-22 minutes, until the coating is golden and the cheese edges are browned.

Let the crisps rest on the rack for 3 minutes so the cheese firms up. Sprinkle with parsley if using and serve warm with marinara, ranch, or garlic yogurt sauce.
