What do you need to make this?

  1. 3 onions (I like vidalia onions)
  2. 1 tablespoon of balsamic vinegar
  3. 2 tablespoons of oil – pretty much any oil will work here. Some oils are likely to burn faster such as olive oil, so, using a canola, vegetable, and or grapeseed might work best for you.
  4. Kosher Salt!


  • You are going to want to use a heavy bottomed pan or pot and set your burner to medium heat. Heat the oil first and then add the onions and cook for around 10 minutes. Make sure that every onion comes in contact with the bottom during that 10 minutes as you want them to start to soften.
  • Add the kosher salt and stir to combine. Lower your heat to medium low and let the onions sit for the next 20 minutes. If you are tempted to stir them, only do it every 8-12 minutes.
  • You are going to cook the onions for 15 more minutes. Stir them every 5 minutes (aka 3 times). Then stir in your balsamic and cook for 5 minutes more. If you like your onions to be really jammy and delicious, cook them for another 15-20 minutes. This is of course optional!
