Set your oven to 350°F (175°C).
Grease your baking dish with butter.
This prevents sticking and adds extra flavor.
Crack eggs into your mixing bowl.
Add milk, sugar, and vanilla extract.
Whisk everything together until smooth and combined.
Sprinkle in the nutmeg and salt.
Mix well so spices distribute evenly.
Add the melted butter and stir again.
Pour mixture into your greased baking dish.
Place dish in the preheated oven carefully.
Bake for 40-45 minutes until set.
Insert a knife in the center.
It should come out mostly clean.
The center might jiggle slightly—that's perfectly fine.
Let it cool for 10 minutes.
Serve warm or at room temperature.
Enjoy with whipped cream if you like!
