This recipe can be prepared a day ahead and can easily be doubled or tripled. I garnish each serving with a dab of sour cream. By adding chicken and rice, you can turn it into a main course.—Kathy Schrecengost, Oswego, New York
In a large saucepan, saute onions in butter until tender, about 2-3 minutes. Add garlic; cook 1 minute longer. Stir in flour until blended. Gradually add broth. Bring to a boil; cook and stir for 2 minutes or until thickened. Reduce heat; simmer, uncovered, for 15 minutes. Stir in cayenne.
