Ingredients

3 TBSP Olive Oil More as needed
5 Large Onions Finely sliced
Pinch Salt Optional
1 tsp Brown Sugar Optional
1 TBSP Balsamic Vinegar Optional

Instructions

Heat a large skillet over medium heat.
Add 2 TBSP of the olive oil.
Finely slice the onions and add to the skillet.
Add the salt if using at the start. If using brown sugar or balsamic vinegar, add after the onions have been cooking for about 10 minutes.
Cook for 20 to 30 minutes, stirring occasionally. Stir only enough to prevent them burning. If you stir too much, they won't caramelise.
Add additional oil or a little water as needed to prevent burning. Balsamic vinegar can help with stopping the onions from sticking to the pan.
Reduce the heat to low and continue to cook for another 15 to 30 minutes until the onions are caramelised.
