Beef topside is a cut of beef taken from the round of the cow. Generally this is one of the leanest, or most fat-free, cuts of beef available, but it is often bought surrounded by a layer of fat. The cut can be used in many different dishes, such as Beef bourguignon and it can also be roasted whole or stir-fried. As a result of the low fat content of the cut, it is best cooked slowly in order to prevent the meat from drying out. Top round is another common name for this cut.
