The definitive guide

What is sirloin steak?

Sirloin steak – pronounced Sur-loyn – is a cut of beef from the mid-back of a cow; between the Fore Rib (In front), Rump (below) and Flank (below). Because the muscles that make up this region of a cow are used substantially during its life, Sirloin steaks are often quite lean — with high protein and low intermuscular fat (or ‘marbling’) contents. Besides being famed for its tenderness, Sirloin steak is known to be notably 'beefy' in taste — lending itself nicely with strongly flavoured sides or sauces.

History of sirloin steak

The word Sirloin derives from the french term “surlonge” — sur for 'above' and longe for 'loin'. There’s also a long history of urban myths surrounding the origins of the beef sirloin name! The most popular of these is that in the 1600’s, King James I knighted a loin of beef after falling head-over-heels in love with its taste during a meal; “Arise, Sirloin”, he said!

Choosing the perfect sirloin steak

Grass fed

The first priority for selecting sirloin steak should always, always be to make sure it comes from a cow that was grass-fed. Briefly, this firstly ensures your sirloin is healthy to eat (grass-fed cows produce beef with higher amount of vitamins, minerals and omega 3 fatty acids), and second, significantly finer in taste. Check out our grass fed beef cheat sheet to learn more important info on the benefits of grass fed beef.

Grass-fed Sirloin steak can be easily spotted by the dark, rich red color of its meat and it’s ‘orangey’ fat color. Don’t be alarmed by the latter — it’s like that because the cow that produced this steak had a very, very healthy beta-carotene level; an antioxidant vitamin (Vitamin A) it got from the healthy, natural and unadulterated grass it ate throughout it’s life.

Ageing

You’ve probably seen the term “aged” dotted around the sirloin steak you buy — whether in the local supermarket or on a dinner menu. Without diving too deeply here, the ageing of meat is crucial for the development of its taste and tenderness.

There are two main strands of ageing practices: Dry-ageing and Wet-ageing. While you can read all about their differences and make your own judgement in our ultimate guide to ageing beef, for a balance of both premium taste and texture we recommend a mix of both! In terms of time, Sirloin steak should always, always be aged for 21 days at a minimum. That's when the Sirloin really hits it’s sweet spot when it comes to taste!

Storing Sirloin Steak

How long a sirloin steak can be stored before going bad depends on two factors: firstly, whether it’s being stored fresh or frozen temperatures, and second, how the meat is packaged. Sirloin steak that is being stored in a standard fridge, using standard packageing (paper wrap, plastic bag or tray) will likely last between 1 - 2 days or upto 2 weeks if vacuum packed.

If you’re storing your sirloin steak in the freezer however, expect it to last very well for between 6 - 12 months if it’s been packaged conventionally. However, if your sirloin steak has been packaged in a vacuum sealed pack, it can last up to 2 - 3 years, without losing any of it’s flavour!
