# Expert Advice:

01 -
  • The first bite is so fresh and fluffy, nobody will guess it’s mostly veggies and egg whites.
  • It’s endlessly customizable depending on what’s lurking in your fridge.
02 -
  • Adding too many fillings will stop the eggs from setting—and I’ve ended up with more scramble than omelette a few times.
  • Covering the pan during cooking keeps the texture fluffy and just-cooked, not rubbery—my game changer.
03 -
  • Room temperature eggs whip up with more volume, so plan ahead if you want mega fluffiness.
  • A little patience over low heat is worth it—nothing ruins this recipe faster than rushing.
