Fillet Steak

What is Fillet Steak?

Fillet steak – pronounced Fill-ette – is cut from a cow carcass’ tenderloin muscle, located towards the back of the rib cage. Because this muscle does not bear any weight of the cow, it’s not exercised and unlike almost all other steaks, it’s connective tissues are not toughened. Ultimately, this delivers the very softest, most tender cut of beef one can find! Despite being so tender, the fillet steak is almost always a very lean cut of meat with little intermuscular fat (marbling) — giving it a finer, more subtle taste than other steak cuts. This also means the fillet steak suits itself nicely with every and any setting, side or sauce!

History of Fillet Steak

The word Fillet derives from the french term “filet” — which translates literally to “thick slice”. As this suggests, fillet steaks are traditionally cut into relatively thicker slices as, unlike other steaks, their surface area is by nature limited by the small diameter of the round tenderloin. Each cow carcass typically delivers about 2 Kg of fillet steak which, alongside its unique tenderness and texture, makes it the most expensive steak!

Choosing the perfect Fillet Steak

Grass fed vs Grain fed Fillet Steak

Though this might not always be immediately available, it’s very important to ensure that the fillet steak you select has come from a cow that has been grass fed. Grass fed fillet steaks are healthier to eat (grass fed beef has higher % of vital vitamins, minerals and omega 3 fatty acids) and is much, much richer in taste!

Fillet steaks from a grass-fed cow are hallmarked by their dark red color, paired with an ‘orangey’ (rather than traditionally, pale white) fat coloration. This orangey color stems from the vitamin A filled natural grass the cow has eaten throughout it’s life. To learn more about the benfits of grass fed beef, check out our definitive guide on Grass fed beef!

Ageing Fillet steak

Some say that dry-ageing fillet steaks delivers the best taste and tenderness while others swear by Wet-ageing. We’re not going to dive into the intricate differences (there are many) here, but our strong recommendation is to find beef that you try to source fillet steaks that have been both dry and wet aged for a total of 21 days! Having experimented endlessly, we’ve found that this delivers the best balanced taste and flavor! Click here to read more about what the experts say on dry and wet ageing.

Storing Fillet Steak

If stored in a standard fridge, fillet steak will likely last between 3 - 5 days regardless of how it has been packaged. When frozen, fillet steak can last for 6 months when packaged normally in plastic. If frozen and vacuum packed, fillet steak will very comfortably last for up to (and even over) 1 year without losing any of its flavour.
