French Onion Soup


  • 50 Grams 50 butter

  • 2 tbs 2 olive oil for frying

  • 800 Grams 800 onion, thinly sliced

  • 1 tsp 1 sugar

  • 2 2 garlic cloves, grated

  • 2 tbs 2 plain flour

  • 2 tbs 2 French mustard

  • 1200 ml 1200 beef stock

  • 350 ml 350 dry white wine

  • 20 ml 20 dry sherry

  • 4 4 Slices French bread

  • 50 Grams 50 cheese grated


  • Heat oil and butter in a Casserole dish, add the onions and cook for approx. 5 mins until the onions start to turn dark.
  • Turn to lowest heat add the sugar, mix and cook for another 25 mins so you get a caramelisation on the onions. Be sure to keep stirring every couple of minutes so the onions don't burn. Add a little water or wine if required.
  • Add garlic, salt and pepper and cook for a further five minutes.
  • Slowly add the flour whilst stirring.
  • Add half a cup of wine to deglaze the pan stirring the rich caramelised onions with a wooden spoon.
  • Turn up the heat and stir in the mustard, stock and wine.
  • Bring to the boil lower heat and add the sherry (optional) cover and simmer for 45 minutes
  • Slice the bread into approx. 2.5 cm thick pieces brush both sides with a little olive oil and grill lightly on both sides. (you are looking for a pale color)
  • Put into 4 flameproof dishes or one large, and place bread on top spreading generously with your favorite cheese. Strong cheddar works well.
  • Place under the grill to melt and serve immediately.
