Ingredients

6 large onions thinly sliced
60 g unsalted butter
1 tbsp olive oil
2 cloves garlic minced
1 tbsp plain flour
250 ml dry white wine or sherry
1.5 l beef broth
1 bouquet garni thyme, bay leaf, and parsley
salt to taste
freshly ground black pepper to taste
1 large baguette sliced and toasted
200 g Gruyère or Emmental cheese, grated

Instructions

In a large pot, melt the butter with the olive oil over medium heat.
60 g unsalted butter, 1 tbsp olive oil
Add the sliced onions and cook, stirring occasionally, until they are caramelised and golden brown, about 45 minutes to 1 hour. Be patient, as this slow cooking process is essential for developing the soup's rich flavour.
6 large onions
Add the minced garlic to the pot and cook for an additional 1-2 minutes until fragrant.
2 cloves garlic
Sprinkle the flour over the onions and stir well to coat. Cook for another 2-3 minutes to eliminate the raw flour taste.
1 tbsp plain flour
Pour in the white wine or sherry, scraping up any browned bits from the bottom of the pot. Simmer until the liquid is reduced by half, about 5 minutes.
250 ml dry white wine
Add the beef broth and bouquet garni. Bring the soup to a simmer and cook for 30 minutes, allowing the flavours to meld together.
1.5 l beef broth, 1 bouquet garni
Season with salt and freshly ground black pepper to taste.
salt, freshly ground black pepper
Preheat your grill to high.
Ladle the soup into ovenproof bowls. Place a slice of toasted baguette on top of each bowl and generously sprinkle with grated cheese.
200 g Gruyère
Place the bowls under the grill until the cheese is melted and bubbly, about 3-5 minutes.
Serve the soup immediately, accompanied by additional slices of baguette and a simple green salad. Pair with a glass of dry white wine or a light red, such as a Beaujolais.
