Best Cooking Methods for Beef Sirloin
Our Grain-Fed Sirloin is perfect for achieving a succulent and tender finish, thanks to its optimal fat rendering. Ideal for chefs and home cooks alike, this sirloin's boneless form ensures even cooking across methods like pan-searing, grilling, barbecuing, or oven roasting. Enjoy consistent results by adjusting heat levels to your preferred doneness.
Pan Sear: Use a medium-high heat to quickly sear both sides, locking in juices. Allow the sirloin to rest for a few minutes before slicing to ensure tenderness.
Grill: Preheat your grill to a medium setting. Grill each side for approximately 6-8 minutes, depending on thickness, to achieve a perfect medium-rare doneness.
BBQ: Set your barbecue to a medium-low heat. Cook slowly to render the fat fully, enhancing flavor and ensuring a melt-in-your-mouth experience.
Oven: Roast at 180°C (350°F) for 20-25 minutes per kilogram. Let the sirloin rest after cooking to allow the juices to redistribute for maximum flavor and juiciness.
Delivery & Storage
Store at or below 4 degrees Celsius Cook thoroughly before consumption. For best quality, use before the recommended best-before date.
Striploin
Striploin, also known as Sirloin, New York Strip, or Porterhouse (when bone-in), is a premium cut prized for its bold flavour and balanced tenderness. It comes from the short loin of the cow and features a fine grain with a satisfying bite. It's a favourite among chefs and home cooks alike for its generous marbling and robust, beefy taste.
Frequently Asked Questions
Our Beef
Where does our beef come from?
All of our beef is from our parent company Stanbroke Beef. This is important as the quality of the beef and ultimately your eating experience is determined by the care that has been shown to the animal during each stage of the production process. Any undue stress the animal experiences at any stage of its life is detrimental to the beef it will produce.
As Stanbroke owns and operates each stage of the production process, strict best practices are followed to ensure the animals always receive the highest of care and that’s why at Peter Augustus we can guarantee the quality of our product each and every time.
SB Marble Scores
What is an SB Marble Score?
The SB Score measures intramuscular fat (the white flecks in the meat). Higher scores mean more marbling, which results in superior tenderness, juiciness, and a richer, buttery flavour.
Which score should I choose?
SB 0–2: Leaner, traditional beef flavour with a robust texture.
SB 3–5: Our "everyday premium" level; a perfect balance of flavour and tenderness.
SB 6–10: The indulgent peak, featuring extreme marbling for a melt-in-your-mouth experience.
Meat Quality & Colour
What is vacuum sealing and how does it extend shelf life?
Vacuum sealing removes air from the packaging, slowing oxidation and bacterial growth to extend freshness and shelf life. When stored correctly at 0–4°C, you can expect the following guide:
Beef primals & whole cuts: up to 28 days
Beef (steaks): up to 21 days
Beef (bone-in): up to 14 days
Lamb: up to 28 days
Pork: up to 10 days
Ham: up to 30 days
Sausages: up to 9 days
Chicken (frozen): up to 12 months
Salmon (frozen): up to 12 months
Smoked salmon: up to 30 days
For longer storage, keep products frozen at -18°C, where vacuum sealed meat can last 1 to 3 years depending on the cut and consistency of temperature.
Once opened, the shelf life reverts to that of standard fresh products, so we recommend consuming promptly.
For longer delivery routes, some items may arrive partially or fully frozen to ensure they remain within safe temperatures during transit.
Why is my steak dark in the vacuum pack?
Our beef is vacuum sealed to lock in freshness and extend shelf life by removing oxygen. This can cause the meat to appear darker or slightly purplish due to natural myoglobin, which is completely normal.
Once opened, simply let your steak rest out of the packaging for 10 to 20 minutes. As it’s exposed to air, it will “bloom” back to its natural rich red colour. Rest assured, your beef is fresh and perfectly safe to enjoy.
Is it safe to eat?
Yes. If the “Use By” date is within range your meat is fresh. Any colour variation from vacuum sealing is normal and will return to its natural red once opened and allowed to bloom.
Delivery & Packaging
What are your delivery fees?
We offer a range of pickup and delivery options to suit you:

Can I request custom cutting instructions?
Yes, our butchers are happy to accommodate custom cutting requests where possible and safe to do so. For example, you may like a rump cap portioned into steaks. Simply specify your preferred thickness or weight per piece, such as approximately 2.5cm or 300g portions.
You can add these instructions in the “View Cart” section before checkout using the notes box or send them through to us via email.
How is my order kept cold?
We use specialist refrigerated courier partners to keep your order within the cold chain from dispatch to delivery.
