Once carrots are soft and have changed color, sprinkle flour and parsley on top. Stir, then let it cook for 2 minutes.
1/4 cup flour, 1 teaspoon dried parsley
Add chicken stock slowly, stirring constantly to avoid lumps. Let it simmer for 10-15 minutes, then puree with immersion blender.
4 cups chicken stock
If you don't have one, use a regular blender, but please follow the usual safety precautions: don't fill it more than 1/3 full of hot liquid at a time, and always use a kitchen towel or an oven mitt to protect your hand while you hold the lid on.
Add chicken and stir, then add salt and pepper to taste. Serve immediately
