There is no single type of steak. Different cuts come from different muscles, and each has its own combination of tenderness, fat content, and flavour that makes it better suited to specific cooking approaches. Understanding the differences allows you to choose the right cut for the occasion and cook it in a way that gets the best from it.

Eye Fillet (Tenderloin)

The eye fillet is cut from the psoas muscle, a long strip that runs along the spine and does almost no work during the animal's life. This inactivity makes it extraordinarily tender. The trade-off is relatively low fat content and a milder flavour than working muscles.

Best cooking method: high-heat searing in a cast iron pan or on a grill to medium-rare (54 to 57 degrees Celsius internal). It does not benefit from long cooking and becomes dry and chalky if overcooked. Serve simply with minimal accompaniment to allow the texture to speak for itself.

Ribeye (Scotch Fillet)

Cut from the rib section, the ribeye is widely considered the most flavoursome steak cut. It has substantial intramuscular fat and often includes a spinalis dorsi muscle cap that is particularly rich and tender. The high fat content means it is forgiving and remains juicy even when cooked to medium.

Best cooking method: high-heat pan searing or barbecue. A bone-in ribeye benefits from a reverse-sear: gentle oven heat first to bring the internal temperature to 50 degrees, then a ripping hot sear to develop the crust. Resting is critical.

Sirloin (Striploin)

The sirloin has less marbling than the ribeye but a denser texture and a deep, well-developed beefy flavour. A strip of fat runs along one edge and renders beautifully during cooking, basting the meat and contributing to the overall flavour. Many experienced steak eaters prefer sirloin for its characterful flavour.

Best cooking method: very hot pan with the fat-cap edge seared first to render before laying flat. Cook to medium-rare and rest well before serving.

Flat Iron (Oyster Blade Steak)

The flat iron is seam-cut from the shoulder blade and has outstanding marbling for a shoulder cut. Its flavour rivals the ribeye at a lower price point and it requires skilled butchery to prepare well, as a line of connective tissue must be removed during the seaming process.

Best cooking method: quick, high-heat cook to medium-rare. It does not suit long cooking and becomes tough when overcooked. An excellent everyday steak for flavour-conscious home cooks.

T-Bone and Porterhouse

Both cuts are defined by a T-shaped bone that separates a sirloin on one side from a fillet on the other. The porterhouse has a larger fillet section and is cut from further back along the loin. Both offer the experience of two different muscles in a single cut, which requires some care during cooking as the two sides have different ideal doneness points.

Best cooking method: barbecue or very hot pan. Cook to medium-rare on the sirloin side and rest for at least five minutes before serving directly on the bone.

Rump Steak

Cut from the hindquarter, rump is a lean steak with an intense, slightly grainy flavour. It has excellent flavour when sourced from a quality animal. Slicing across the grain after cooking and resting significantly improves the perceived tenderness.

Best cooking method: high-heat sear, cooked no more than medium. Marinades work well with rump and can help tenderise the muscle fibres before cooking.

Choosing the Right Steak for the Occasion

For a special occasion where tenderness is paramount: eye fillet or ribeye. For everyday cooking where flavour matters most: sirloin, flat iron, or rump. For the barbecue where you want theatre as well as taste: T-bone, porterhouse, or tomahawk ribeye.
