Makes 4 servings.  

 

 

What You Need  

 

 

4 tablespoons (½ stick) butter  

4 large onions, thinly sliced (about 6 cups)  

4 cups beef, chicken or vegetable stock  

1 tbsp flour  

2 or 3 sprigs fresh thyme or a pinch of dried thyme  

1 bay leaf  

Salt & freshly ground black pepper  

1 cup white wine  

4 slices toasted baguette with butter  

1 cup freshly grated Parmesan, Gruyere or Emmental cheese  

 

 

How to Prepare Classic French Onion Soup  

  

1) Melt the butter in a large, deep pot over medium heat.  

2) Add onions and cook, stirring occasionally, until very soft and beginning to brown. This can take 30 – 45 minutes. The longer it cooks, the better the flavor so take your time and keep the temperature low so they don’t brown too fast.  

3) Sprinkle the onions with the flour and cook for 1-2 minutes.  

4) Add beef stock and wine then raise the heat to medium high. Cook until simmering.  

5) Lower heat and add herbs, salt & pepper. Cook at a low simmer for 15 minutes.  

6) While the soup is simmering, toast slices of buttered baguette in the oven.  

7) Fish the thyme sprigs and bay leaf out of the soup then ladle into oven safe bowls.  

8) Top each bowl with a crouton and grated cheese.  

9) Put soup bowl under the broiler for 5-10 minutes until the cheese is melted and golden. Serve!
