🥩 Why Choose King River Wagyu Rump
A few good reasons this cut belongs in your cart.
-
Grain fed wagyu sourcing: King River raises wagyu on a long grain finish, building the rich, even marbling that makes this rump eat well above its price.
-
Independently graded MB9+: This sits at the top end of the marbling scale, so you get dense intramuscular fat running right through the cut.
-
Serious marbling at value pricing: MB9+ marbling usually costs a fortune, but on rump you get that buttery richness for a fraction of the premium cut price.
-
Whole piece value: Buying the full 6.5 kg lets you cut your own steaks, portion roasts, and stretch the value across a dozen meals or more.
-
Cryovac sealed freshness: Every piece is vacuum sealed to lock in moisture and flavour from our cold room to your kitchen.
-
Fair price on premium beef: At $59/kg this is genuine MB9+ wagyu rump at a price that makes weeknight wagyu a real thing.

🍷 Flavour and Texture
Rump brings the boldest, beefiest flavour of the popular steak cuts, and the wagyu marbling rounds it out with a buttery richness you can taste in every bite. The texture has a satisfying bite without being tough, and the MB9+ fat keeps it juicy from edge to edge. This is a cut with real character.
It loves a confident hand with seasoning. Salt, pepper, and a hot grill is all a rump steak truly needs, though a chimichurri or peppercorn sauce takes it further. Pair it with a bold Shiraz or a cold lager, and serve alongside roast potatoes, grilled vegetables, or a loaded salad.
🔥 How to Cook King River Wagyu Rump
The golden rule with wagyu rump is to cook it hot, keep it to medium rare, and always rest it before slicing against the grain.
For steaks: Cut the rump into steaks around 2.5 to 3 cm thick. Bring them to room temperature, pat dry, and season generously with salt. Sear in a screaming hot pan or on the grill for about 3 to 4 minutes each side for medium rare, aiming for an internal temperature of 52 to 54C. Rest for 5 minutes, then slice against the grain for maximum tenderness.
For a whole roast: Bring the piece to room temperature and season well. Sear all sides in a hot pan to build a crust, then transfer to an oven at 180C. Roast for roughly 15 to 18 minutes per 500 g for medium rare, pulling it at an internal temperature of 52 to 54C. Rest for 15 minutes under foil before carving thin slices across the grain.
Pro tip: always slice rump against the grain. It is the single biggest thing that turns a good rump steak into a tender one.

🧊 Packaging and Storage
Your rump arrives cryovac sealed to protect freshness and lock in moisture during transit. The vacuum seal also makes it easy to break the piece down and freeze portions straight away if you are not cooking it all within the week.
Store chilled below 4C and use within 10 days, or freeze at minus 18C for up to 12 months. To defrost, move the sealed meat to the fridge and allow 24 to 48 hours to thaw slowly. Never thaw at room temperature, as a gentle defrost protects the texture.
❓ FAQ
What is King River wagyu rump best used for?
It is best used for steaks, roasts, and high value meal prep. Cut it into thick rump steaks for the grill or pan, roast the whole piece for a crowd, or slice it thin for stir fries. The high MB9+ marbling means it performs well across nearly every cooking method.
How long does wagyu rump last in the fridge?
Sealed in its original cryovac, the rump keeps for up to 10 days refrigerated below 4C. Once opened or portioned, cook it within 2 to 3 days for best quality. For longer storage, freeze it at minus 18C for up to 12 months.
What is the difference between rump and sirloin?
Rump and sirloin are neighbouring cuts, but rump has a bolder, beefier flavour and a slightly firmer bite, while sirloin or porterhouse is a touch more tender. Rump also offers far better value by the kilo, which is why it is a favourite for steak lovers who cook often.
