It’s a classic Montreal night: the air is cold, maybe a little snowy, and all you want is warmth. Now, imagine walking into a cozy, dimly lit restaurant. A small, round bowl arrives, steaming hot, topped with a thick, bubbly layer of golden, melted cheese. You break through the crust with your spoon, and the rich, savory smell washes over you. That’s the simple, perfect feeling of digging into French onion soup.
This dish, known here as Soupe à l’Oignon Gratinée, is the ultimate comfort food. It’s a classic that started in France, and it’s famous for its deep flavor that just warms you up from the inside out.
And here in Montreal, we make it shine. Because of our strong French history, our excellent bistro culture, and those famously long, cold winters, this soup is truly at home here.
Let’s dig deeper!
The Anatomy of a Perfect French Onion Soup
What separates a truly great French onion soup from a watery, disappointing one? It comes down to a careful three-step process that builds deep, savory flavor.
Step 1: Caramelization is Key
This is where all the magic starts. You can’t rush this step. The onions (usually a mix of yellow and sweet) must be cooked low and slow, often for 45 minutes to a full hour. This long, gentle heat breaks them down completely, turning their sharp flavor into a deep, natural sweetness. If the onions are rushed, they taste bitter; if they’re perfect, they taste like liquid gold. This slow process gives the soup its signature color and depth.
Step 2: The Rich Base
Once the onions are caramelized, they need a partner: a rich, high-quality stock. The stock is the backbone of the soup, and it must be powerful. The best French onion soup uses a strong beef or veal stock that has been slowly simmered to draw out all the savory flavors. This isn’t the time for thin, watery broth; you need something that tastes deep and hearty, ready to soak up the onion sweetness.
Step 3: The Assembly
The final act is the most fun and visually striking. Before the soup is ready to serve, it is built up in three layers:
- The Crouton: A slice of sturdy bread or a thick crouton is placed on top of the broth. Its job is to act as a raft for the cheese and to soak up the liquid without completely dissolving into mush.
- The Cheese: This is non-negotiable. You need a cheese with a strong, nutty flavor and a great melt. The most authentic choice is Gruyère (sometimes mixed with Emmenthal). It forms that irresistible, stretchy, savory crust.
- The Gratinée: The bowl is then placed under a hot broiler. This high heat quickly melts and browns the cheese, creating a bubbly, golden, sealed crust, the famous gratinée.
It’s this balance of deep sweetness, savory broth, and salty, melted cheese that makes the perfect bite.
Why Montreal Does French Classics Justice
It’s no accident that the best French onion soup often seems to be served outside of France. Montreal, in particular, is the perfect city for this dish to thrive. Here are the three main reasons why the gratinée in Montreal always tastes so right:
The Historical Link
Montreal is deeply rooted in French history. Because of this heritage, the city has preserved classic recipes and techniques with genuine pride. Unlike trends that come and go, dishes like Soupe à l’Oignon Gratinée are never forgotten here.

The Weather Factor
Let’s be honest: Montreal winters are serious. When you’re dealing with six months of cold weather, you need fuel and comfort. French onion soup is perfectly suited to chase away the chill. It’s an easy-to-love combination of savory broth and heavy, melted cheese that warms you from the inside out.
