Before you start cooking, make sure you have all the necessary ingredients for this delightful French onion soup recipe:

6 large onions (yellow or white)
1/2 cup unsalted butter
2 tablespoons olive oil
1 teaspoon sugar
4 cloves garlic (minced)
8 cups beef broth
1/2 cup dry white wine
2 bay leaves
1 tablespoon fresh thyme (or 1 teaspoon dried thyme)
Salt and pepper to taste
French baguette (sliced)
2 cups Gruyre cheese (grated)

Step-by-Step Cooking Method

1. Caramelize the Onions

Start by slicing your onions thinly. In your Dutch oven, melt the butter and olive oil over medium heat. Add the onions and toss them to coat in the butter mixture. Sprinkle sugar over the onions to help with caramelization. Cook the onions for approximately 45 minutes, stirring occasionally. They should turn a deep, rich brown color.

2. Add Garlic and Herbs

Once your onions are caramelized, add the minced garlic, thyme, and bay leaves. Cook for another minute until the garlic is fragrant.

3. Deglaze with Wine

Pour in the dry white wine to deglaze the pot, scraping up any browned bits stuck to the bottomthat's where the flavor is! Let it simmer for about 5 minutes.

4. Add Broth and Simmer

Add the beef broth, bringing it to a boil. Once boiling, reduce the heat and let it simmer for 30 minutes. Season with salt and pepper to taste.

5. Prepare the Baguette and Cheese

While the soup simmers, preheat your oven to 350F (175C). Slice the French baguette and arrange the slices on a baking sheet. Bake until golden brown, then flip them to toast the other side. Sprinkle the grated Gruyre cheese on top of the toasted baguette slices.

6. Combine and Serve

Ladle the soup into oven-safe bowls. Place a slice or two of the cheesy baguette on top of each bowl. Place the bowls on a baking sheet and broil until the cheese is melted and bubbly. Serve immediately and enjoy the delighted smiles of your guests!
