The origins of French onion soup trace back to the humble inns of 18th‑century Paris, where it was a dish of frugality and flavor. I recall reading that a famous chef once served it to a royal guest, and the broth’s depth won their praise. This tradition lives on in every simmered pot, a reminder that simple ingredients can create elegance. For a glimpse of that era’s cuisine, explore the mustard chicken that once graced provincial tables.

Ingredients
Main Ingredients
-
01
6 large yellow onions, thinly sliced
-
02
4 tbsp unsalted butter
-
03
2 tbsp olive oil
-
04
1/2 cup dry white wine
-
05
8 cups low‑sodium beef broth
-
06
2 tsp fresh thyme leaves
-
07
1 bay leaf
-
08
Salt and freshly ground black pepper to taste
-
09
1 baguette, sliced
-
10
2 cups grated Gruyère cheese
Instructions
In a large heavy pot, melt butter with olive oil over medium‑low heat. Add the sliced onions, a pinch of salt, and stir to coat.
Cook the onions, stirring occasionally, for about 30‑35 minutes until they turn a deep caramel color, being careful not to let them burn.
Add the wine, scraping the browned bits from the bottom, and let it reduce for 3‑4 minutes.
Stir in the broth, thyme, and bay leaf. Bring to a gentle simmer and let it cook for 20 minutes, seasoning with pepper and more salt if needed.
While the soup simmers, preheat the oven broiler. Place baguette slices on a baking sheet and toast until lightly golden, about 2 minutes per side.
Ladle hot soup into oven‑safe bowls, float a toasted baguette slice on top, and sprinkle generously with Gruyère.
Place bowls under the broiler until the cheese bubbles and turns a deep golden brown, about 3‑4 minutes. Serve immediately.
