Step 1 –Preheat the oven to 400 degrees F.

Step 2 –Spray a square 2-quart baking dish with the olive oil spray.

Step 8 –Transfer the zucchini mixture to the prepared baking dish.

Step 9 –Sprinkle the mixture with the remaining mozzarella and the parmesan.

Step 10 –Bake, uncovered, until the cheese is bubbly and browned, about 30 minutes.
