Slimming World’s Roast Beef with Mustard Crust

Serves 4-6

Ready in about 2 hours



3 ½ pounds sirloin of beef, all visible fat removed

3 tablespoons English mustard powder

6 to 8 teaspoons mixed peppercorns, crushed


Preheat the oven to 375oF and place the beef in a roasting pan. Make up the mustard according to the packet instructions and spread over the joint. Sprinkle over the peppercorns to form an even crust.

Place the meat in the oven and cook for 20 minutes per pound plus an extra 20 minutes for rare; 25 minutes per pound plus an extra 25 minutes for medium; and 30 minutes per pound plus an extra 30 minutes for well done. Baste occasionally with the meat juices while roasting, and turn halfway through its cooking time.

Once cooked, remove the beef from the roasting pan and cover loosely with foil. Allow it to rest for 15-20 minutes before carving. Delicious served with roasted vine tomatoes.
