Ingredients
  • 1 tbs good quality olive oil
  • 25 g butter
  • 1 1/2 kg onions - peeled and thinly sliced - I used a mix of white and red
  • 4 fat cloves garlic - peeled
  • Salt & Pepper
Instructions
  1. Place the oil and butter in a large non stick pan or wok, place over a low heat and allow to melt.
  2. Add the onions and garlic and stir well.
  3. Allow to cook until reduced, brown and caramelized, stirring every 5 minutes to prevent the onions sticking and burning. This may take up to an hour and a half.
  4. Season well to taste.
Recipe Notes

Caramelized onions will keep in the fridge for up to a week in an airtight pot. 

Freezes well.

To make this recipe vegan, omit the butter and use double the quantity of oil.
