Ingredients

  • 1kg (2.2 lb) Beef sirloin or scotch fillet roast
  • 2 tbsp Olive oil
  • 4 Garlic cloves, smashed
  • 4 Fresh thyme sprigs
  • 1 tbsp Dijon mustard
  • 2 tsp Fine sea salt
  • 1 tsp Black pepper
  • 500g (1 medium head) Cauliflower florets
  • 3 tbsp (40g) Unsalted butter
  • 50ml Heavy cream
  • 200g Broccoli florets (for serving)
  • 100g Green beans (for serving)

Method

  1. Take the beef out of the fridge 30 minutes before cooking to come to room temperature. Preheat the oven to 400°F (200°C).
  2. Pat the beef dry. Rub all over with olive oil, Dijon, smashed garlic, thyme, salt, and pepper.
  3. Place the beef on a rack over a roasting tray. Roast 20 minutes at 400°F to develop a crust, then reduce to 325°F (160°C) and continue roasting until the internal temperature reads 130°F (55°C) for medium-rare, about 40-50 more minutes for a 1kg roast.
  4. Transfer the beef to a cutting board, tent loosely with foil, and rest 15 minutes.
  5. While it rests, steam the cauliflower until very soft (8-10 minutes), then blend with butter, cream, salt, and pepper until silky.
  6. Steam the broccoli and green beans together for 4-5 minutes, until bright and just tender.
  7. Carve the beef against the grain into thick slices. Plate over the cauli mash with broccoli and green beans alongside. Spoon any resting juices over the meat.
