Ingredients

For the Soup

• 4 large yellow onions, thinly sliced
• 3 tbsp butter
• 1 tbsp olive oil
• 1 tsp sugar
• 2 cloves garlic, minced
• ½ cup dry white wine
• 6 cups beef broth (or vegetable broth for a vegetarian option)
• 2 sprigs of thyme
• 1 bay leaf
• Salt and pepper to taste

For the Topping

• 1 baguette, sliced into 1-inch rounds
• 1 cup grated Gruyère cheese (or Swiss cheese)
• 2 tbsp butter for toasting

Step-by-Step Instructions

Step 1: Caramelize the Onions

1. In a large pot or Dutch oven, melt 3 tbsp of butter with 1 tbsp olive oil over medium heat.
2. Add the sliced onions and cook, stirring occasionally, for about 15 minutes.
3. Sprinkle 1 tsp sugar over the onions to help them caramelize.
4. Continue cooking for 20-30 minutes, stirring frequently, until the onions are deep golden brown and fragrant. Be patient—this step is key to the soup’s rich flavor!

Step 2: Add Garlic and Deglaze the Pot

1. Add the minced garlic to the onions and cook for another minute.
2. Pour in the white wine and stir, scraping up any browned bits from the bottom of the pot (this step is called deglazing).
3. Let the wine simmer for 5 minutes to reduce slightly.

Step 3: Simmer the Soup

1. Add the beef broth, thyme sprigs, and bay leaf to the pot.
2. Season with salt and pepper to taste.
3. Bring the soup to a boil, then reduce the heat and simmer for 30-40 minutes to allow the flavors to meld.

Step 4: Prepare the Cheese Toasts

1. While the soup is simmering, preheat the oven to 375°F (190°C).
2. Brush the baguette slices with butter on both sides and place them on a baking sheet.
3. Toast the baguette slices in the oven for 8-10 minutes until golden brown.
4. Remove from the oven and sprinkle Gruyère cheese generously on top.

Step 5: Broil the Cheese Toasts

1. Switch the oven to broil mode.
2. Place the cheese-topped toasts under the broiler for 2-3 minutes until the cheese is melted and bubbly. Watch closely to prevent burning.

Step 6: Serve the Soup

• Ladle the hot soup into oven-safe bowls or crocks.
• Place 1-2 cheese toasts on top of each bowl of soup.
• If desired, broil the assembled bowls for 1-2 minutes to melt the cheese further.

Tips and Tricks for Perfect Onion Soup

• Use yellow onions for the best balance of sweetness and flavor.
• Caramelize slowly: Rushing this step can result in burnt onions rather than the rich, golden color you want.
• For a vegetarian option, swap the beef broth for vegetable broth.
• Try adding a splash of brandy for extra depth of flavor.
