This recipe was given to me by an old French lady who has been making it for her family for more than 70 years and they never tire of it – it’s so delicious!

Did you know that onions were – in ancient times – considered an aphrodisiac?  In France in the old days it was customary for newlyweds to be served onion soup on the morning after their wedding night.

Thanks to Janine Marsh from TheGoodLifeFrance for this scrumptious recipe; another take on a great classic.

A French Onion Soup Recipe


  • ·         50g unsalted butter
  • ·         750gm onions – (any type will do but chop them finely)
  • ·         1 large clove of garlic, chopped – (or more if you like)
  • ·         40gm plain flour
  • ·         2 litres of good quality beef or chicken stock
  • ·         250ml white wine
  • ·         1 bay leaf
  • ·         2 sprigs thyme
  • ·         Stale baguette
  • ·         100g finely grated Gruyère cheese


1. Melt the butter in a saucepan and add the onions, stir occasionally over a low heat for about 20 mins until they are a deep golden colour and starting to caramelise.

2. Add the garlic and flour to the onions and stir constantly for 2 minutes.

3. Gradually add the stock and wine stirring constantly and then bring to the boil.

4. Season and add the herbs, cover the saucepan and simmer for around 20 minutes

5. Slice the stale baguette and toast them lightly – then break into small pieces about an inch or so across or you can leave the slices whole if you prefer.

6. Serve the soup into dishes, whack the bread on top, sprinkle with the grated cheese and grill until the cheese is bubbling and you can’t wait any longer to get stuck in!

PS If you want to freeze left over soup leave out the bread and cheese and it’ll last in the freezer for a couple of months. Enjoy!
