What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Whisk the egg whites until foamy but not stiff — this incorporates air for a light, fluffy texture without making them dry.
- 2Cook the mushrooms until all moisture has evaporated; wet mushrooms will make the egg whites soggy.
- 3Use a non-stick skillet and keep the heat on medium-low to prevent the egg whites from browning or turning rubbery.
- 4Let the omelette set around the edges before adding the filling — the center should still be slightly glossy for a perfect fold.
- 5Warm your serving plate so the omelette stays hot and fluffy while you garnish and serve.
- 6Make-ahead tip: Sauté the mushrooms and onions up to 2 days in advance and reheat briefly before assembling the omelette.
