Grate the zucchini and squeeze out excess water using a clean towel. This step is key to avoid a watery casserole.
2. Mix the base
In a large bowl, combine zucchini, eggs, milk, shredded cheese, Parmesan, breadcrumbs, onion, garlic, salt, and pepper. Mix well until everything is evenly combined.
3. Assemble
Grease a baking dish and pour the mixture evenly into it. Smooth the top with a spatula.
4. Bake
Bake at 180°C for 30–35 minutes until the top is golden brown and slightly crispy.
5. Serve
Let it cool for a few minutes, then slice and serve warm. The inside should be soft and creamy with a cheesy crust on top.
