Ingredient Notes & Easy Substitutions
- Eggs: Fresh eggs create the best texture. Whisk thoroughly to incorporate air and make the omelette lighter.
- Mushrooms: Cremini, button, or baby bella mushrooms all work well. Slice them evenly so they cook at the same rate.
- Spinach: Fresh spinach works best, but frozen spinach can be used if fully thawed and drained.
- Onion: Adds sweetness and depth to the filling. Yellow, white, or red onions can be used.
- Extra Virgin Olive Oil: Helps cook the vegetables and eggs while adding a mild richness. Butter can be used for a more classic omelette flavor.
- Dried Oregano: Adds herbal flavor, but fresh herbs like parsley or basil can also be used.
