Pot-au-feu literally translates into English as “pot on the fire”. It is a classic French beef stew, a peasant dish at heart. Traditionally made from beef bones and stewing beef, the broth is typically served as a clear soup, preceding the main dish of sliced beef with vegetables which have been cooked in the broth. It is honest and hearty French fare. Although the dish may take several hours to cook, you are not required to do much during this time, other than to skim the surface of the soup and to check that the meat is continually submerged. This makes it an ideal dish to make when you have time to potter about the kitchen and can look forward to a simple, yet satisfying, supper.
Recipes abound for pot-au-feu and they are all variations of the same blue-print. The beef bones are necessary to add richness and depth to the soup, and oxtails are perfect for this type of cooking, in part because you can also eat the tender and sweet meat later. But the stewing beef is what is traditionally served at the table, so you should find a cut which needs a few hours of cooking time, such as beef brisket or beef shank. In Switzerland, the beef is often labelled “Pot-au-feu”, making it clear what the cut is intended for. But “Bouilli de boeuf maigre” is also a good choice. In Australia, I recall buying cuts of meat simply labelled “soup beef” which would be perfect here. You could also use beef cheeks, which are wonderfully tender and flavoursome upon cooking, though they take longer to cook and you might need to order these from your butcher.
