Preheat your oven to 375°F (190°C).

Grease a shallow pudding dish with butter.

In a mixing bowl, soak the crumbled stale bread in the milk until softened.

Beat the soaked bread mixture until smooth.

Add the beaten eggs and salt to the bread mixture, and mix well to combine.

Pour the mixture into the prepared pudding dish.

Bake in the preheated oven for about 10 minutes, or until the omelette is set and lightly golden brown on top.

Remove from the oven and serve the Baked Bread Omelette immediately in the same dish, as it will fall quickly.
