Slow cook: Cover the slow cooker with the lid and cook on LOW for 7 to 8 hours, or on HIGH for 4 to 5 hours, until the beef is very tender and can be easily pulled apart with a fork. Avoid lifting the lid too often; each peek releases heat and can lengthen the cooking time.
Adjust and serve: Once the beef is tender, taste the gravy and adjust with a splash of water or additional broth if it’s thicker than you’d like.
