Step 1

Combine the chicken broth and 1/2 cup of the milk in a large saucepan. Bring to a low boil.

Step 2

Meanwhile, in a small bowl, whisk the flour and seasonings into the remaining 1 cup milk until a smooth, thick mixture forms.

Step 3

Pour the flour and milk mixture into the saucepan with the broth mixture over low heat and stir continuously, whisking as the mixture simmers. Continue to simmer and stir/whisk until the mixture is smooth and thick, 5-10 minutes. The mixture will thicken a bit as it cools.
