The roast and au jus can be used immediately after cooking, but for beef that is easier to cut into thin slices and broth with less fat, place the broth-covered roast in the fridge overnight in an airtight container. The next day, the roast will be easy to cut into thin slices and the layer of fat can be discarded once it is cold. Reheat the beef and broth in the microwave until hot.
*It is also easier to freeze the beef and au jus after it has been refrigerated. Wrap the beef separate from the au jus to freeze. It works well to freeze the beef and au jus in serving portions that suit you and/or your family. Always, cook five pounds of beef, It freezes beautifully, and will keep up to 3 months.
