The winning combination of garlic and mustard make great British beef taste even greater - the perfect Sunday dinner


  • 1.5kg (3lb 5oz) boned and rolled sirloin or topside of beef
  • 2 garlic cloves, peeled and sliced
  • 45ml (3tbsp) English mustard powder
  • 15ml (1tbsp) sunflower oil
  • 8 small onions, halved
  • 30ml (2tbsp) runny honey

When buying beef, look for marbled cuts: this is more flavoursome and tender because the fat lubricates the meat during cooking, adding another layer of flavour.


  1. Preheat the oven to 230C (450F, gas mark 8). With the tip of a knife, make about eight incisions into the beef and push a slice of garlic into each hole. Blend the mustard powder to a paste with 45ml (3tbsp) cold water.
  2. Place the joint in a roasting tin and spread the mustard paste all over the joint. Season with salt and freshly ground black pepper and drizzle over the sunflower oil.
  3. Roast in the hot oven for 20 mins, then reduce the oven temperature to 190C (375F, gas mark 5) and roast for a further 1 hr 30 mins-2 hrs - depending on how well done you like the beef. Baste occasionally with any meat juices.
  4. About 1 hr before the end of cooking time, spoon 45ml (3tbsp) of the meat fat into a smaller roasting tin. Add the halved onions and turn to coat in the hot fat. Roast for 30 mins, then brush over the honey and roast for a further 30 mins until tender and light golden.
  5. Place the beef on a platter, cover loosely with foil and leave to rest in a warm place for 20 mins before carving. Serve with the roast onions.
