Ingredients
  

Main Ingredients
  • 1 kg brown onions, peeled Feel free to swap in yellow onions for a milder taste.
  • 2 tbsp olive oil
  • 2 tbsp salted butter You can use unsalted butter if that’s all you have on hand.
  • 1 large pinch sea salt flakes
  • 1 tbsp balsamic vinegar Can substitute with red or white wine vinegar, or even a teaspoon of sugar.

Method
 

Cooking Process
  1. In a large, heavy-based pot, melt the olive oil and butter together over low heat for about 2–3 minutes.
  2. Use a mandolin to thinly slice the onions. Once sliced, add them to the pot.
  3. Sprinkle with a generous pinch of sea salt and stir to coat the onions in the oil and butter.
  4. Cook on low heat for 40–50 minutes, stirring every 10 minutes, until the onions are golden-brown.
  5. Add the balsamic vinegar and cook for an additional 10–15 minutes, stirring occasionally, until you achieve dark brown, gooey, and sweet onions.
