The Ultimate French Onion Soup: A Decadent Twist with Brie Croutons

French Onion Soup holds a revered place in culinary history, cherished for its profound flavors and comforting warmth. It’s a dish that embodies rustic elegance, a culinary masterpiece born from humble ingredients. At its core, this classic features deeply caramelized onions, simmered in a rich, savory beef broth, crowned with a generous, cheesy crouton. This recipe, however, introduces a delightful elevation, transforming the traditional into an unforgettable gourmet experience by swapping the usual Gruyère for a luxuriously buttery, triple-cream brie.

We’re thrilled to partner with the esteemed Quebec cheesemakers at Alexis de Portneuf to bring you this refined recipe. While Gruyère is undeniably a superb choice, we’ve discovered that their exquisite Saint-Honoré triple cream brie offers an unparalleled creamy richness and a delicate buttery flavor that melts into pure indulgence. Imagine a giant, gooey baked brie, perfectly browned, resting atop your soup – it’s a revelation that promises to elevate every spoonful.

If you appreciate fine cheeses and inventive pairings, you might recall our previous collaboration with this lovely fromagerie. We previously shared a delectable Roasted Grape and Broiled Camembert Crostini recipe, further solidifying our shared passion for good, melty cheese on bread. Alexis de Portneuf also offers a fantastic at-a-glance system to help you discover new cheeses tailored to your palate – an invaluable resource for any cheese lover.

The Magical Transformation: Perfect Caramelized Onions

Let’s take a moment to truly appreciate the humble onion. It’s a vegetable that holds a definite wonder. Raw, its pungent aroma can bring tears to your eyes, a testament to its sharp, assertive character. Yet, through the simple alchemy of heat and time, this very same vegetable undergoes a profound transformation, evolving into a sweet, amber-hued marvel. This change isn’t just a softening; it’s a deep caramelization, where natural sugars emerge, creating an unparalleled depth of flavor that is absolutely essential to French Onion Soup. This process, requiring only a warm stove and a generous dose of patience, is nothing short of culinary magic.

Caramelizing the onions is, without a doubt, the most patience-requiring step in this recipe, and it cannot be rushed. Attempting to speed it up often results in burnt, bitter onions rather than the desired sweet, golden perfection. The key is low to medium heat and consistent, gentle stirring over a sustained period. This slow process allows the onions to release their moisture, soften, and then gradually brown as their sugars caramelize. While it demands time, it’s not active labor. You can easily do this part in advance, letting the onions slowly transform on a back burner while you prepare other meals, or even the day before. This foresight can significantly streamline your soup-making process, making it a perfect weekend prep task. Many home cooks, myself included, often find this meditative process quite enjoyable, turning what could be a chore into a calming kitchen ritual.

Serving Suggestions and The Essential Broth

A restaurant-quality French onion soup is almost always served in special oven-proof crocks, designed to withstand the broiler and maintain the soup’s warmth. These charming bowls, often with handles, are perfect for showcasing that iconic cheesy crust. I found mine years ago at a local Canadian store, but there are many similar options available online. However, don’t let the lack of specific crocks deter you. You can easily adapt! Simply broil the brie on top of toasted baguette slices on a baking sheet, and then carefully transfer these decadent cheese toasts to any soup bowl you possess. In fact, these gooey brie toasts are so good, they could stand alone as an appetizer or even elevate a simple salad – imagine them on a bed of lightly dressed greens, perhaps with a sprinkle of dried cranberries, for an effortlessly elegant starter.

Because French Onion Soup relies on such a concise list of ingredients, the quality of each component is paramount, especially the beef stock. A truly excellent beef stock can take your soup from good to extraordinary. It forms the very backbone of the soup’s flavor profile, providing depth and savory richness that cannot be replicated with inferior alternatives. While making beef stock from scratch is a rewarding endeavor that offers unparalleled flavor (a quick Google search will provide ample recipes!), many high-quality options are available commercially. Look for artisanal varieties at your local market or inquire with butchers, who often sell fresh or frozen homemade stock. Avoid heavily processed broths or those with artificial flavors; a good quality, robust beef broth will make all the difference, harmonizing beautifully with the sweet onions and rich brie.

French Onion Soup with Giant Brie Croutons

By:

Jennifer Pallian BSc, RD

Classic French Onion Soup topped with a gooey baked brie crouton.

Prep Time:

15 minutes

Cook Time:

1 hour
15 minutes

Total Time:

1 hour
30 minutes

Servings:
4

Ingredients

• 4 tbsp butter
• 3 lbs yellow onions halved lengthwise and thinly sliced crosswise
• salt
• ½ cup dry white wine
• 6 cups beef broth
• 1 ½ cups water
• 3 sprigs thyme leaves
• 1 bay leaf
• ½ tsp pepper
• 6 slices baguette
• 1 200- gram Saint-Honoré brie

Instructions

1. Heat the butter in a heavy-bottomed pot or Dutch oven (at least 5 quarts/liters) over medium heat. Add onions and a pinch of salt. Cook onions, stirring occasionally, until they are deep golden brown, about 40 minutes. This slow process is crucial for developing the rich, sweet flavor.
2. Add white wine and cook, stirring, for 2 minutes to deglaze the pot and incorporate its delicate flavors. Add beef broth, water, thyme, bay leaf, pepper, and a good pinch of salt (the exact amount will depend on the salinity of your broth, so taste and adjust later). Bring to a boil, then reduce heat to low, cover the pot, and simmer for 30 minutes to allow the flavors to meld beautifully.
3. Meanwhile, preheat oven to 450ºF (230°C). Arrange baguette slices on a baking sheet and toast for 4 minutes on each side, until lightly golden and crisp.
4. Ladle the hot soup into oven-proof bowls or ramekins. Top each bowl with a toasted baguette slice. Generously cover the toast with a slice of Saint-Honoré brie. Broil until the cheese is bubbly, golden, and beautifully melted, typically just a minute or two. Watch very closely to prevent burning.
5. Alternatively, you can leave the toasted baguette slices on the baking sheet, arrange the brie on top, and broil them that way. Once the cheese is bubbly and golden, carefully transfer these exquisite cheese toasts to top individual soup portions in regular bowls. Serve immediately and enjoy the warmth and rich flavors!
