How to cook roast beef

When it comes to roast beef, the received wisdom is that it should always be cooked on the bone – whether it's a sirloin joint or rib roast – as the bone conducts heat and adds flavour. However, this doesn't suit everyone and some of our most popular recipes are bone-free and much easier to carve. Buy what suits you best.

More important than the bone is the fat – don't be tempted to trim it off, as it will baste your meat while it cooks. You can always cut it away when you serve it. If you want the fat to make a crust, then you have to sprinkle or rub it with flour and/or mustard powder to absorb the fat released on the surface.

Generally, roast beef is cooked at a high temperature to caramelise the outside, then the temperature is turned down. This method can also be reversed with a lower temperature to start before a blast of heat at the end. As an example, see our herb-scented slow-roasted recipe.

Roast beef cooking time

If you don't have a meat thermometer, check your beef is roasted by piercing it with a skewer. The juices should run red for rare, pink for medium and clear for well-done. Also, a meat thermometer should read 40C for rare (it will rise to 54-56C, medium-rare, as it sits) or 48C for medium (it will rise to 65C).

It's essential you rest your joint for at least an hour so the juices are reabsorbed. If you carve the beef too soon, it will be dry rather than juicy. Some juices will be released as it sits and you can tip these into the gravy.

If cooking beef on the bone, a three-rib roast (about 3kg) will serve about seven to eight people. Calculate roughly 400g per person. If cooking beef off the bone, 1kg will serve four and 1.5kg will serve about six, so 200-300g per person. Calculate your cooking time for medium-rare with 20 minutes per 500g or for medium use 25 minutes per 500g.

For beef on or off the bone, cook it at 240C/220C fan/gas 9 for 20 minutes, then turn down to 180C/160C fan/gas 4 (not forgetting to take this 20 minutes off the timing you have just calculated).
