Get out your trusty slow cooker. Then take the Beef Chuck (5 pound) and trim any excess fat.
Lay the beef out in the bottom of the slow cooker, then pile the Yukon Gold Potato (6), Carrot (6), Onion (3), Garlic (2 clove), and Fresh Rosemary (1 sprig) on top of it.
Then stir the Beef Consommé (3/4 cup), Ketchup (1/4 cup), Apple Cider Vinegar (1/4 cup), Worcestershire Sauce (2 tablespoon), Salt (1 teaspoon) and Freshly Ground Black Pepper (1/2 teaspoon) together in a bowl and pour it into the crock pot. Seal the slow cooker with its lid and cook everything on low for 8 hours. Then serve immediately!
