Frequently asked questions
How can I tell when the onions are ready?
They should be softened and evenly golden, with a sweet aroma and no blackened edges.
How do I know the omelette is set?
The surface should look mostly set rather than wet, and the center should feel tender but not runny.
Can I make this ahead?
It is best cooked just before serving. You can chop the onion ahead and keep it covered in the refrigerator.
