How Long Do You Cook Roast Beef?

Roast beef and all the trimmings is a quintessential Sunday roast dish served with crispy roast potatoes, a selection of seasonal vegetables and tasty gravy, (the base of which is made from the meat juices) – something quite special. But how long do you cook roast beef for?

The first roast beef cooking tip to impart to you is to ensure that you start cooking your roast beef on a high temperature setting for a short period at the beginning of the cooking time, around 240°C (475°F) for the first 20 minutes. By blasting the joint with a high heat for a short period at the beginning of cooking this serves to create a tasty crust around the joint that will taste amazing and will also cosmetically produce a fine looking joint color if you should be carving at the table in front of family and friends.

Cooking time for some of the most popular cuts of roasting beef such as Sirloin, topside, toprump, silverside, and rib of beef (boneless and bone in) are as follows:
