Basler Mehlsuppe

Step by stepInstructions

1. Melt the butter in a heavy pot over medium-low heat. Add the flour and cook, stirring constantly, until it turns a deep golden brown and smells nutty, 8–10 minutes. Do not let it burn.
2. Add the onion and cook 2 minutes more. Slowly whisk in the beef broth until smooth.
3. Add the caraway, nutmeg, salt, and pepper. Simmer gently 20 minutes, whisking now and then.
4. Ladle the soup over the bread slices in warm bowls and top each with grated Gruyère before serving.
