Instructions

0/4
  1. Slicing

    Thinly slice the onions into 2mm strips. Uniformity is key so that all pieces cook at the same speed.

    10 min
  2. Sweating

    Heat olive oil in a wide sauté pan. Add the onions and a pinch of salt to draw out their moisture. They should become translucent.

    5 min
  3. Slow caramelization

    Lower the heat to minimum. Cook while stirring regularly. The onions will turn from golden to a hazelnut brown. They must not burn but candy in their own sugar.

    40 min
  4. Deglazing

    Add the red wine vinegar. Scrape the bottom of the pan with a spatula to release the browned bits. The mixture should be glossy and the sauce should coat the onions.

    5 min

Chef's tips

  • Patience is your only secret ingredient: never turn up the heat to go faster, you would burn the bitterness instead of releasing the sugar.
  • If the onions stick too much at the end of cooking, add a tablespoon of water to restart the caramelization without burning the juices.

Storage

Keeps for 5 days in the refrigerator in an airtight jar or 3 months in the freezer.
