Instructions

Heat a large stainless steel or cast iron pan over medium heat. Add the olive oil to the pan and heat through, then add the butter and allow to melt.
Working in batches, add the onions and toss quickly to remove the moisture from the onions. Sauté, stirring occasionally, until the onions are soft and start to brown.
Sprinkle the sugar and salt over the onions, stirring to combine. Reduce the heat to medium-low and cook, stirring occasionally, until the onions are light brown and begin to caramelize, about 20 minutes.
Continue to cook, stirring frequently, until the onions are uniformly brown and caramelized, about an additional 10 minutes. Remove the pan from heat. Let the caramelized onions cool and use or store until ready to use.
