Preheat your oven to 180°C (350°F).

Using a clean kitchen towel or cheesecloth, squeeze out the excess moisture from the grated zucchini and potatoes.

In a large mixing bowl, combine the grated zucchini, potatoes, chopped onion, grated carrot, and chopped parsley.

Stir in the beaten eggs, salt, black pepper, and breadcrumbs. Mix thoroughly to ensure all ingredients are well combined.

Grease a baking dish with olive oil. Pour the vegetable and egg mixture into the dish, spreading it out evenly.

Sprinkle the shredded mozzarella cheese evenly over the top of the mixture.

Bake in the preheated oven for 25-30 minutes, or until the cheese is golden brown and bubbly, and the bake is cooked through.

Allow the bake to cool for a few minutes before slicing and serving.
