Detailed Directions and Instructions
Preheat the Oven
Preheat your oven to 140°C/285°F (120°C fan-forced).
Prepare the Beef
Pat excess moisture off the surface of the rump cap using paper towels.
Score the Fat Cap
Score the fat cap in a diamond pattern with cuts approximately 2.5cm / 1″ deep. Ensure you cut well into the fat but avoid cutting into the meat.
Rub with Salt and Pepper
Rub 2 teaspoons of sea salt and half of the black pepper onto the meat surface, including the underside and sides. Then, rub the remaining 3 teaspoons of salt and the remaining pepper into the scored fat cap.
Insert Meat Thermometer
If using, place the beef on a rack set on a tray and insert an oven-safe meat thermometer into the thickest part of the beef.
Slow-Roast the Beef
Roast the beef until the internal temperature reaches 48°C / 118°F. This should take between 70 to 90 minutes, though time may vary.
Rest the Beef
Remove the beef from the oven and let it rest on the counter for 30 to 40 minutes without covering it. During this time, the internal temperature will rise to approximately 56°C / 132.8°F for a perfect medium rare finish.
Preheat the Grill/Broiler
About halfway through the resting period, preheat the oven grill/broiler to its highest setting. Adjust the shelf so the fat cap is 12cm / 5″ away from the heat element.
Brown the Fat Cap
Grill the rump cap for 2 to 3 minutes until the fat cap is golden and slightly crisp. Monitor closely to prevent burning, and remove it after 3 minutes even if it’s not completely golden to avoid overcooking the beef.
Slice and Serve
Slice the beef thinly into pieces about 8mm / 1/3″ thick and serve with your choice of sauce. If using wagyu, slices can be up to 1.25cm / 1/2″ thick. Avoid cutting thick slices as this cut is not suitable for that.
Notes
Note 1:
If using cooking salt or kosher salt, adjust the quantity to 3.5 teaspoons for the meat.
Note 2:
The internal temperature for desired doneness varies; for medium, aim for approximately 60°C / 140°F.
Note 3:
The cooking time may vary based on the oven and the size of the beef cut.
Note 4:
For different levels of doneness, refer to various temperature guidelines.
Note 5:
When slicing, follow the grain direction of the meat for the best texture.

Cook techniques
Scoring the Fat Cap
Cut the fat cap into diamonds about 2.5 cm / 1 inch apart, ensuring you slice deeply into the fat without cutting into the meat. This helps render the fat and enhances flavor during cooking.
Salting the Meat
Rub 2 teaspoons of salt into the meat surface and apply the remaining 3 teaspoons onto the fat cap along with half a teaspoon of black pepper. This will enhance the flavor and help with moisture retention during cooking.
Using a Meat Thermometer
Insert an oven-safe meat thermometer into the thickest part of the beef to monitor the internal temperature while it slow-roasts.
Slow-Roasting
Roast the beef at a low temperature of 140°C / 285°F until it reaches an internal temperature of 48°C / 118°F, typically taking between 70 to 90 minutes.
Resting the Meat
Once removed from the oven, let the beef rest on the counter for 30-40 minutes uncovered, allowing the internal temperature to rise to 56°C / 132.8°F for perfect medium-rare.
Browning the Fat Cap
During the resting phase, preheat the oven grill/broiler to its highest setting. Place the beef close to the heat source and grill for 2-3 minutes until the fat cap is golden and slightly crisp, watching carefully to prevent burning.
Slicing for Serving
Cut the beef into thin slices, about 8 mm / 1/3 inch thick. Avoid slicing too thick, as this cut is best enjoyed when thinly sliced against the grain.
