6. Pour Egg Mixture: Carefully pour the egg mixture over the entire casserole, ensuring it is evenly distributed.

7. Bake: Place the baking dish in the preheated oven and bake for 45-50 minutes, or until the eggs are set in the center.

8. Cool: Remove from the oven and let it cool for about 10 minutes before serving.

9. Garnish: Sprinkle chopped green onions on top for a fresh touch.
