Panera's Broccoli Cheddar Soup

In large soup pot or Dutch oven, melt the butter over medium heat. Add the onion and cook until softened and translucent, about 3 minutes. Add the garlic and carrots (if using) and cook 1 minute more. Do not brown.

Add the flour and cook, stirring constantly, for 1 minute. Gradually add the chicken broth, whisking constantly. Add the broccoli, salt, pepper, and nutmeg and bring to a gentle boil. Reduce the heat to low, cover, and simmer for 10 minutes.

Add the cream and bring back to a simmer, uncovered. Gradually stir in the cheese until completely melted. Taste and adjust seasoning, if necessary. Ladle the soup into bowls and top with more cheese, if desired.
