## Step-by-Step Instructions
### 1. Caramelize the Onions
The secret to a great French onion soup lies in the caramelization of the onions. Heat butter and olive oil in a large, heavy-bottomed pot over medium heat. Add the sliced onions and stir to coat evenly. Sprinkle with sugar and cook slowly, stirring frequently, for about 40-50 minutes, until the onions are golden brown and soft. Patience here makes all the difference—it develops the deep, sweet flavor essential to the soup.
### 2. Add Garlic and Flour
Stir in the minced garlic and cook for another minute until fragrant. Sprinkle the flour over the onions and stir well to combine. This will help thicken the soup slightly. Cook for 2-3 minutes, allowing the flour to toast lightly but not burn.
### 3. Deglaze with Wine
Pour in the white wine or sherry, scraping the bottom of the pot to loosen any browned bits. This adds complexity and depth to the flavor. Let the alcohol cook off for about 2 minutes.
### 4. Add Broth and Herbs
Slowly add the beef broth, stirring to combine. Toss in the bay leaf and thyme, then bring the soup to a simmer. Reduce heat to low and let it cook gently for 30 minutes. Season with salt and pepper to taste.
### 5. Prepare the Bread
While the soup simmers, preheat your oven’s broiler. Lay the baguette slices on a baking sheet and toast until golden on both sides, about 2 minutes per side.
### 6. Assemble and Broil
Ladle the hot soup into oven-safe bowls or crocks. Place one or two toasted baguette slices on top of each bowl, then generously sprinkle with grated Gruyère cheese. Place the bowls under the broiler for 3-5 minutes, until the cheese is melted, bubbly, and golden brown.
### 7. Serve and Enjoy
Carefully remove the bowls from the oven (they will be hot!) and serve immediately. Enjoy the perfect balance of sweet onions, savory broth, and cheesy bread in every spoonful.

## Tips to Elevate Your French Onion Soup Recipe
– **Use quality beef broth:** For the richest flavor, homemade broth or a high-quality store-bought brand is best. You can also use a mix of beef and chicken broth for a lighter flavor.
– **Watch your caramelization:** Don’t rush the onions. Stir often and use medium-low heat to avoid burning.
– **Cheese choices:** Gruyère is traditional, but Emmental or Swiss cheese also work well. For extra richness, mix in a little Parmesan.
– **Make ahead:** The soup base can be made a day in advance and reheated. Toast the bread and broil the cheese just before serving for best texture.
