What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Whisk egg whites just until frothy — over-whisking makes them too airy and difficult to cook evenly.
- 2Use a non-stick skillet and keep the heat low when cooking the egg whites to prevent browning or toughening.
- 3Sauté mushrooms until they release their moisture and start to brown for deeper savory flavor.
- 4Let the omelet cook undisturbed until the edges are set and the center is mostly opaque before folding.
- 5Add the spinach at the very end of sautéing and only until wilted to avoid a watery omelet.
- 6For make-ahead: prep all chopped vegetables the night before and store in the fridge for a faster morning cook.
