Total Time 53 minutes
Servings 4 servings
- 6 cups of thinly sliced onions
- 2 tablespoons butter
- 2 tablespoons olive oil
- 6 sprigs fresh thyme
- 1 bay leaf
- 1/2 cup white wine
- 4 cups good quality beef broth
- 4 slices baguette toasted
- 1 1/2 cups grated Gruyere or similar cheese
In a large skillet with high sides heat the butter and oil over a medium heat. Add the onions, and the thyme leaves and bay leaf. Cook the onions on low heat until the moisture starts to evaporate from the onions. Do not be tempted to rush this process. It takes time. Stir the onions every 10 minutes to avoid them catching on the bottom of the pan.
Once the onions are a deep caramel color, deglaze the pan with the white wine and bring to a boil to burn off the alcohol. Add the beef broth or chicken broth and bring back to a boil while the broiler pre-heats.
Once the broiler is hot, ladle the soup into the oven-safe bowls and top with the baguette slices and divide the cheese evenly among the 4 bowls. Place the bowls under the broiler until the cheese is melted, golden and bubbly.
Garnish with extra thyme leaves.
Some recipes may call for adding some baking soda to the onions. Do not do it. The onions turn a very unappetizing greenish yellow and turn to mush.
Don't add sugar to the onions to help the caramelizing process. It makes the onions far too sweet.
