Why is water often added to the eggs when making an omelette? Also, is there a recommended amount of water?

    I find that water makes watery omelettes, where milk makes a much richer omelette. I prefer to use heavy cream if I have it around. Water certainly makes a healthier omelette...

Eggs are already 3/4 water anyway!

By mixing in a small quantity of extra water before you cook the eggs, you are slowing down the cooking process by making more water available that has be evaporated. This keeps the cooking temperature to less than 100°C (212°F) for longer, therefore increasing the the time for the egg proteins to foam and expand before setting

The amount of water you need to add depends on; personal preference, the type of egg, and how old it is. Older eggs generally require a little more water

Adding skim milk will enhance this process slightly too. Adding extra fat will generally not enhance this process

BONUS TIP To make even more spectacular omelettes place a loose fitting lid over the pan to increase the steam exposure all around, and let the egg fully develop

  • and when should we add the water or milk? right from the start or when the egg starting to whitening?

  • Thank you, TFD! I wondered why a meringue recipe called for a small amount of water to be added, and I think this is probably the reason.

To get fluffier eggs.

When the water is heated to 100 degrees C, the water will begin to evaporate. This will in turn make lots of small holes in the egg giving fluffy eggs.

Recommended amount of liquid (water or milk): 1 tbsp pr egg.


Using water does make the taste a lot better because the protein is a lot richer.

    Not deleting, because it seems vaguely close to a real answer, but there's nowhere near enough explanation here to be a good answer.
