Top tip for making the best egg white omelette
In recipe testing, we found that the one thing that could ruin an egg white omelette was overwhipping the eggs. For one, it caused the omelette to puff up dramatically during cooking which made it impossible to cook without flipping the omelette (too much work and risk tearing it).
Even more importantly, overwhipping the egg whites made an omelette that was rubbery tasting, like overcooked eggs. This is definitely something that you want to avoid.
To make a soft egg white omelette, make sure to only lightly whip the whites. They should look liquidy with only a few bubbles in them.
How to cook an egg white omelette
- Cook the filling first: Add the shallot to a pan and cook it until it's translucent. Then add the tomatoes, spinach, salt, and pepper and cook them until the tomatoes are warm and the spinach has wilted.
- Prepare the egg whites: Lightly whisk the egg whites, garlic powder, salt, and pepper. You want there to be a few foamy bubbles, but it should still be liquid underneath them.
- Cook your eggs: Melt the butter and when it starts to bubble, pour the egg whites into the pan and swirl the pan to spread them out. Cover the pan with a lid and let the egg whites cook undisturbed for 3 minutes, or until they are no longer wet on top.
- Assemble your omelette: Add the cheese to one half of the omelette then top the cheese with the filling. Fold the omelette in half then put the lid back on the pan for 1 minute to let the cheese melt.
