In the Slow Cooker
Dump frozen or thawed beef and sauce mixture into the slow cooker. Cook on High for 3 – 4 hours or Low 6 – 7 hours. Stir occasionally during cooking.
Gravy
If the cooked beef mixture needs more liquid for gravy...add beef broth one-half cup at a time and stir. Add more broth until the gravy reaches a consistency you like.
