How Do You Speed Up Caramelized Onions?
To speed up the caramelization of onions, first make sure that the onions are sliced thinly and evenly. Use a wide pan with low sides and heat it over medium-high heat. Add a teaspoon of sugar and a pinch of salt to the onions and stir frequently. Once the onions have started to sweat and release their juices, lower the heat to medium-low and continue to stir occasionally until they have reached your desired level of caramelization. Adding a splash of balsamic vinegar or deglazing the pan with a bit of white wine can also help speed up the caramelization process.
