French Onion Soup

A litre of deeply caramelised onions suspended in veal and beef stock, covered with a thick raft of day-old baguette and blanketed in Comte or Gruyere that is grilled until charred at the edges. The secret is time — properly caramelised onions require 60 to 90 minutes of patient stirring over low heat. The shortcuts visible in inferior versions (pale onions, powdery stock, thin cheese) are immediately apparent.

The Method

1
Heat butter and oil in a heavy-bottomed pot over medium heat; add onions and sugar, cook uncovered 35–40 minutes, stirring occasionally, until deep golden and caramelised.
2
Add wine and deglaze, scraping browned bits; simmer 5 minutes to reduce by half.
3
Pour in stock, add bay leaves and thyme, bring to simmer, and cook 15 minutes; season carefully with salt and Tellicherry pepper.
4
Discard bay leaves and thyme; divide soup among four ovenproof bowls.
5
Top each bowl with a toasted baguette slice; pile Gruyère AOP over bread.

6
Place under a preheated grill 3–4 minutes until cheese melts and bubbles; serve immediately.

Sensory Tests

◇Where it lives or dies. The moment where French onion soup lives or dies is the caramelisation window — specifically the last 20 minutes when the onions shift from pale gold to deep mahogany. At this point, they stick to the pan and must be stirred constantly. Resist the urge to add more butter or wine to prevent sticking — instead, let them catch slightly, then deglaze with a splash of stock. This catching and deglazing, repeated three or four times, builds the deepest layers of flavour.

Origin & Lineage

Paris, France. Associated with Les Halles market, where the soup was eaten in the early hours of the morning by market workers. Queen Marie Antoinette is apocryphally credited with introducing the dish to Versailles. The gratin-topped version became standard in Parisian bistros in the 19th century.
