# Expert Tips:

01 -
  • Once you whisk those egg whites until they're nearly snowy, the omelette puffs up beautifully—it's a little breakfast magic.
  • It’s endlessly customizable, so you can clear out your veggie drawer and never get bored.
02 -
  • The temptation to crank up the heat almost always leads to browned egg whites and stubborn omelette edges—patience pays off here.
  • Whisking just until the egg whites are very frothy gives that airy, soufflé-like lift.
03 -
  • Using a truly nonstick pan keeps your omelette pristine when you fold and serve it.
  • Letting the egg whites come to room temperature before whisking gives the best volume.
