Feel free to experiment with different vegetables based on your preference and availability. Broccoli, bell peppers, or mushrooms would be excellent additions. For a richer flavor, consider using a combination of olive oil and butter. A touch of garlic, minced and added with the onion, can also elevate the dish. If you want a crispier topping, broil the casserole for the last few minutes, keeping a close eye to prevent burning.
