***I place my roast in my slow cooker or crock pot on low, the day before we are going to eat it, because I like it to cook nice and slow to be extra tender! I also add the beef stew seasoning packet and water to give it a great flavor.***
Preheat oven to 300. Place roast in a 9 x 13 pan. Surround it with the potatoes, carrots, and onion slices. Pour the juice from the slow cooker over the ingredients in the pan. Cover with aluminum foil. Cook for about 3 hours. Bake some rolls, and dinner is served!
