Ingredients

  • Premium sirloin tip
  • Potatoes
  • Garlic
  • Parsley
  • Parmesan cheese
  • Leek
  • Sliced mushrooms
  • Mushroom sauce
  • Thyme
  • Cucumber
  • Spinach & rocket mix
  • Roasted almonds
  • Balsamic vinaigrette dressing
  • Butter
  • Olive oil
  • Salt & pepper

Method

  1. Preheat oven to 220°C (200°C fan-forced). Halve potatoes lengthwise. Place each half flat-side down between two wooden spoon handles and thinly slice without cutting all the way through. Arrange on a lined baking tray, drizzle with olive oil, season with salt and pepper, and roast for 30–35 minutes.

  2. Finely chop garlic and parsley. In a small microwave-safe bowl, melt butter with garlic in 10-second bursts. Stir in parsley. When potatoes have 5 minutes remaining, drizzle with herby butter, sprinkle with Parmesan cheese, and roast until melted and golden.

  3. Heat a drizzle of olive oil in a large frying pan over high heat. Season sirloin tip all over and sear until browned, 1 minute on each side. Transfer to a second lined oven tray and roast for 17–22 minutes for medium or until cooked to your liking. Remove from oven, cover with foil, and rest for 10 minutes.

  4. While beef is resting, thinly slice leek and mushrooms. Pick thyme leaves. Wipe out the frying pan and return to medium-high heat with a drizzle of olive oil. Cook leek and mushrooms, tossing, until browned and softened, 6–8 minutes. Remove pan from heat, stir in mushroom sauce, thyme, a splash of water, and any beef resting juices. Season to taste.

  5. Thinly slice cucumber. In a medium bowl, combine cucumber, spinach & rocket mix, roasted almonds, and balsamic vinaigrette dressing. Season to taste.

  6. Thinly slice rested beef. Divide beef, Parmesan hasselback potatoes, and cucumber salad between plates. Spoon leek mushroom sauce over the beef to serve. Enjoy!
