Roast Rump with Thai Spices

A great beef roast featuring an unusual cut -a boneless rump roast. Great for all festive occasions, including Christmas. The joint is marinated in a delicious Thai-style marinade (containing sweet chilli sauce, lime zest, lemon grass, fresh ginger and a little oil). A great centre-piece.

  • 1.3kg lean rump roast
  • For the Thai Marinade:

  • 8 tablespoons prepared sweet chilli sauce
  • Grated zest of 1 large lime
  • 3 lemon grass stalks, finely chopped
  • 1 x 5cm piece fresh root ginger, peeled and finely chopped
  • 2 tablespoons rapeseed or olive oil


  1. Preheat the oven to 180-190°C, 160-170°C Fan, Gas Mark 4-5.
  2. For the Thai marinade; in a small bowl mix all the ingredients together.
  3. Place the joint on a chopping board, score the skin, season and brush the marinade all over the joint.  Cover and marinate in the refrigerator for up to 2 hours.
  4. Put the joint on a metal rack in a large non-stick roasting tin and open roast for the preferred, calculated cooking time, basting occasionally with any beef juices.  Cover with foil if browning too quickly.
  5. Remove the joint from the tin, transfer to a warm plate, cover with foil and rest for at least 20 minutes.
  6. Serve the joint with seasonal roasted vegetables.


As alternative, use a whole topside, sirloin or boneless rib joint instead.
