Roasted marinated porterhouse with mushrooms, capsicums and a mustard steak sauce

Method

  • Whisk the beef stock with 3-4 tbsp oil, the rosemary, chilli paste, seasonings, soy, Worcestershire and the juice of ½-1 lemon until well combined in a very large bowl.
  • Then add the beef to the marinade, toss to coat well, cover and refrigerate for 1 hour, turning now and again.
  • When ready preheat oven to 220°C fan forced (240°C normal).
  • Place the beef in a heavy-bottomed oven tray, fat side down and cook in the middle of the oven to the desired degree (about 35 mins for medium-rare), basting with the marinade after about 15 mins. When ready, remove and set aside to rest for 15 mins, loosely covered with kitchen foil, before slicing.
  • After the beef has been cooking for about 15 mins, toss the mushrooms and capsicums with the juice of 1½ lemons, a slurp of oil, seasonings and the garlic in an oven tray. Then cook in the lower shelf of the oven.
  • To make the sauce, combine the mustards with ¾ cup oil, the red onion, ground pepper and parsley. Taste for seasoning and set aside to develop its flavours.
  • To serve, place the beef on a bed of the vegies on individual plates with a good spoonful of the sauce on top.
