Preheat your oven to 375°F (190°C). Grease a 9x13-inch casserole dish with butter or non-stick spray.
Wash the zucchini thoroughly and slice them into thin rounds, about 1/4 inch thick.
In a large skillet, heat the olive oil over medium heat. Add the zucchini slices and sauté for 5-7 minutes, stirring occasionally, until softened and slightly golden. Remove from heat and set aside.
In a large mixing bowl, whisk together the eggs, milk, garlic powder, onion powder, salt, and black pepper until well combined.
Gradually stir the shredded cheddar cheese into the egg mixture, reserving about 1/4 cup of cheese for the topping.
Add the cooked zucchini to the egg and cheese mixture, folding gently to coat all slices evenly.
Pour the zucchini mixture into the prepared casserole dish and spread it out evenly.
In a small bowl, combine the breadcrumbs, grated Parmesan cheese, and melted butter. Mix until the breadcrumbs are evenly coated.
Sprinkle the breadcrumb mixture evenly over the casserole, followed by the reserved shredded cheddar cheese.
Bake the casserole in the preheated oven for 30-35 minutes, or until the topping is golden brown and the casserole is set in the center.
Remove from the oven and let it cool for 5 minutes before serving. Garnish with fresh herbs like parsley if desired.
