Note
Do not try stirring the onions until they have sweated down for the initial 15-20 minutes; this helps them caramelize evenly.
If using an electric skillet, maintain the temperature around 300ðF to prevent burning while ensuring slow cooking.
The dish can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently to melt the cheese again.
For a variation, you can add a splash of balsamic vinegar during the reduction step for extra depth.
