  • 4 red onion sliced
  • 2 tbsp olive oil
  • 1 tsp salt
  • 1 tbsp brown sugar optional
  • 2 tbsp balsamic vinegar
  • 1 tsp chili flakes


  • Heat the olive oil on a low heat and add the onions, chili flakes and salt to the pan.
  • Cook on low for approx 20-30 mins.  Stirring occasionally so they don't stick.
  • Once onions are soft and melted add the brown sugar (if using) and balsamic vinegar.  At this point you will need to keep an eye on it and stir every couple minutes as the colour and caramelization will begin *see tips*
  • Once cooled store in an airtight container in the fridge for a couple months


Essential Tools

  • chopping board
  • sharp knife
  • wooden spoon
  • frying pan


  • the most important one is to make sure to keep the pan on LOW when cooking to allow the natural sugars from onions to release
  • using sugar isn't necessary - there are enough natural sugars in red onions that if cooked low n slow then they will naturally caramelize BUT........
  • honey can be used instead of brown sugar but I like brown sugar better - personally!
