French Onion Soup Recipe

Onions are one of the most popular root vegetables to grow in your garden. Why not celebrate this hardy veggie and make French Onion Soup to warm you on a chilly winter evening?

Serves 2

Prep: 10 mins

Cook: 55 mins



  • 25g salted butter
  • 2 tsp olive oil
  • 500g white onions, thinly sliced
  • ½ tsp soft brown sugar
  • 2 garlic cloves, diced
  • 1 tbsp plain flour
  • 150ml dry white wine
  • 650ml hot rich beef stock
  • 4 slices crusty bread – baguettes work well
  • 70g gruyère, grated finely
  • Handful of fresh thyme, chopped



  • Heavy bottomed saucepan
  • 2 heatproof bowls



Step 1

Add the butter to a heavy bottomed saucepan and melt. Add the thinly sliced onions and fry for about 10 minutes on a gentle heat with the lid on.

Step 2

Once the onions are soft, sprinkle on the sugar and cook for 20 more minutes, ensuring you stir frequently to stop them catching or burning – the onions should caramelise beautifully.

Step 3

Once the onions are a golden colour and soft, add the diced garlic and stir for a few minutes, then add the flour. Stir it all again really well.

Step 4

Increase the heat and gradually add the wine – still stirring regularly. Once all the wine has been added, follow it with the beef stock.

Step 5

Give it all a good mix and then cover and simmer for 15-20 minutes.

Step 6

Turn on the grill and toast the bread lightly. Ladle the soup into two heatproof bowls and put 2 slices of toast on top. Generously add the gruyere.

Step 7

Place both bowls under the grill until the cheese is melted. If your bowls aren’t heatproof, then you can melt the cheese on top of the toast separately and then add them to the soup.

Step 8

Sprinkle with chopped thyme and serve immediately, and enjoy! If you try this recipe, don’t forget to share a photo with us over on our Facebook page, or email us at
