Preheat the oven to 375°F (190°C). Grease a 9x13-inch baking dish with butter and set aside.

Heat olive oil in a large skillet over medium heat. Add the chopped onion and sauté for 3-4 minutes, until softened. Add the minced garlic and cook for an additional minute.

In a large mixing bowl, whisk the eggs until smooth. Add the milk, shredded mozzarella cheese, grated Parmesan cheese, dried oregano, dried basil, salt, and black pepper. Mix well to combine.

Pour the mixture into the prepared baking dish and spread it out evenly.
