Classic French Onion Soup: A Timeless Bowl of Comfort

French onion soup, or soupe à l’oignon, is an iconic dish that hails from France, renowned for its rich flavours and warmth. A culinary staple in French bistros and homes alike, this comforting soup is a delightful blend of caramelised onions, hearty broth, and gooey melted cheese, making it the perfect indulgence, especially on chillier days.

A Brief History

The origins of French onion soup can be traced back to the Roman times when the humble onion was cherished for its flavour and nutritional value. However, the version we know and love today began to take shape in the 18th century. Legends suggest that the popularisation of the dish occurred in Paris, particularly in the late night eateries of the city, catering to those who sought comfort after an evening of revelry.

The traditional method of preparation utilises simple, readily-available ingredients: onions, beef broth, bread, and a generous amount of cheese. As the dish evolved, variations emerged, with some using white wine, while others incorporated herbs and spices for added complexity.

Ingredients and Preparation

The beauty of French onion soup lies in its simplicity, yet the technique is key to achieving that remarkable depth of flavour that defines the dish. Here’s a classic recipe to follow:

Ingredients:

  • 4 large yellow onions, thinly sliced
  • 50g unsalted butter
  • 1 tablespoon olive oil
  • 2 cloves of garlic, minced
  • 1 tablespoon sugar (optional, for caramelisation)
  • 1 litre beef stock (or vegetable stock for a vegetarian version)
  • 150ml dry white wine (optional)
  • Salt and freshly ground black pepper to taste
  • 4 slices of crusty baguette or sourdough
  • 200g Gruyère cheese, grated
  • Fresh thyme leaves (for garnish)

Method:

  1. Caramelise the Onions: In a large, heavy-based saucepan, melt the butter and olive oil over medium heat. Add the sliced onions and cook gently, stirring frequently, until they become soft and translucent, around 30 minutes. If desired, add a tablespoon of sugar to encourage caramelisation. Continue cooking until the onions are a deep golden brown—this can take an additional 20–30 minutes. Patience is key here; a low and slow approach will yield the best flavour.

  2. Add Flavour: Stir in the minced garlic and cook for another minute. If using white wine, pour it in now, scraping up any bits stuck to the bottom of the pan. This will enhance the flavour and add acidity to balance the sweetness of the onions.

  3. Simmer the Soup: Add the beef stock, season with salt and pepper, and bring the mixture to a gentle simmer. Allow it to cook for at least 30 minutes; the longer, the better—considering this a dish that begs for time and patience.

  4. Prepare the Toasts: While the soup simmers, preheat your grill. Place the slices of baguette on a baking tray, sprinkle them lightly with olive oil, and toast them in the grill until golden and crisp.

  5. Serve: Ladle the soup into heatproof bowls, place a slice of toasted bread on top of each bowl, and cover generously with grated Gruyère cheese. Place the bowls under the grill until the cheese is bubbling and golden brown.

  6. Garnish and Enjoy: Finish off with some fresh thyme leaves for flavour and presentation. Serve immediately, and enjoy the aromatic warmth of your homemade French onion soup!
