3 . Stage

Meanwhile, combine chicken broth and flavor packets in a bowl.

4 . Stage

Transfer onion mixture to a 5-quart or larger slow cooker. Add remaining butter to the skillet and heat until melted and bubbling. Stir in flour with a wire whisk; cook and stir for 3 minutes. Slowly whisk in chicken broth mixture and season with salt and pepper. Cook, stirring constantly, until smooth and no lumps remain. Bring to a boil.
