Pour the zucchini mixture into a baking dish, spreading it evenly.
Place the dish in the preheated oven and bake for 20 minutes until the top is golden brown and the inside is cooked to perfection.
After 20 minutes, take the dish out of the oven and uncover it. Return it to the oven for another 10 minutes to ensure that the top is nicely golden brown and crispy.
