1/2 tsp salt
-
2 cloves garlic, minced

1/2 cup dry white wine (or dry sherry)

6 cups beef broth (or half beef, half chicken for a lighter version)
-
1โ2 sprigs fresh thyme (or 1/2 tsp dried thyme)
-
1 bay leaf
-
Salt & pepper to taste

Optional: 1 tbsp flour (for a slightly thicker soup)
For the topping:

1 baguette, sliced into 1/2-inch thick rounds

1 ยฝ cups grated Gruyรจre cheese (or Swiss, Emmental, or mozzarella)
๐จโ๐ณ Instructions:
1. Caramelize the Onions
-
In a large pot or Dutch oven, heat butter and olive oil over medium heat.
-
Add sliced onions, salt, and sugar.
-
Cook slowly, stirring frequently, for 30โ40 minutes until onions are deeply golden brown and caramelized. Donโt rush this step โ it builds the flavor.
2. Deglaze
-
Add garlic and cook for 1โ2 minutes.
-
Pour in the wine to deglaze the pot, scraping up all the brown bits.
-
Let it reduce for a few minutes.
3. Build the Broth
-
Add broth, thyme, and bay leaf.
-
Simmer uncovered for 30โ40 minutes.
-
Remove thyme sprigs and bay leaf.
-
Taste and adjust seasoning with salt and pepper.
-
Optional: stir in a spoonful of flour for a slightly thicker texture.
4. Toast the Bread
-
While the soup simmers, toast the baguette slices until golden (you can rub them with garlic after toasting for extra flavor).
5. Assemble & Broil
-
Preheat your broiler.
-
Ladle hot soup into oven-safe bowls.
-
Place 1โ2 toasted bread slices on top of each bowl.
-
Sprinkle generously with Gruyรจre cheese.
-
Broil for 2โ3 minutes until cheese is melted and bubbly (watch closely!).
No oven-safe bowls? Broil the bread slices separately with cheese, then place them on top of the soup when serving.

Add a crack of black pepper and a few thyme leaves on top before serving.
