How Do You Thicken Brown Gravy With Flour?
To thicken brown gravy with flour, start by making a roux by melting equal parts butter and flour in a saucepan. Cook the roux for a few minutes until it starts to turn a golden color. Then, slowly whisk in the warm broth or liquid from the brown gravy until the mixture is smooth. Continue cooking and stirring until the desired thickness is achieved. Be careful not to add too much flour or the gravy will become too thick and lumpy.
