A good gluten-free French onion soup recipe includes gluten-free croutons and vegetarian stock as opposed to traditional beef stock. Other ingredients include butter, onions, cooking sherry, Gruyere cheese and spices.
The ingredients for the croutons in this recipe include the cook's favorite gluten-free bread, olive oil and garlic powder. A cook makes the croutons by cutting the bread into cubes, brushing it with olive oil and garlic powder and then baking it in the oven at 300 degrees Fahrenheit for 20 to 25 minutes.
To make the soup, the cook sautes the thinly sliced onions in the butter and sea salt in a large soup pot until the onions carmelize. He then adds the sherry and cooks it for about 5 minutes. He pours in the vegetable stock, bay leaf, thyme and Worcestershire sauce and lets it cook for 20 to 30 minutes. The cook pours about 1/2 cup of the broth into a container with a lid. He adds the gluten-free flour mix, covers it, shakes it and then adds it back into the soup.
The cook turns down the temperature on the soup, ladles it into bowls and places the bowls on a cookie sheet. He puts the gluten-free croutons and cheese on top and places the soup under the broiler until the cheese starts to bubble. Now the soup is ready to enjoy.
