Fillet steak – pronounced Fill-ette – is cut from a cow carcase's tenderloin muscle, located towards the back of the rib cage. Because this muscle does not bear any weight of the cow, it is not exercised and therefore, 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 intramuscular fat (marbling) — giving it a finer, more subtle taste than other steak cuts. This also means the fillet steak is paired nicely with every and any setting, side or sauce, and makes a great inclusion for our meat box delivery.
The word fillet is derived from the French term “filet” — which translates literally as “thick slice”. As this suggests, fillet steaks are traditionally cut into relatively thicker slices as their surface area is limited by the small diameter of the round tenderloin. Each cow carcase typically delivers approximately 2kg of fillet steak which, along with its unique tenderness and texture, makes it the most expensive 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 are much, much richer in taste!
Fillet steaks from a grass-fed cow are hallmarked by their dark red colour, paired with an ‘orangey’ (rather than traditionally, pale white) fat colouration. This orangey colour stems from the vitamin A-filled natural grass the cow has eaten throughout its life.

Some say that dry-ageing fillet steaks deliver 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 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 flavour! Click here to read more about what the experts say on dry and wet -ageing.

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 flavours. Why?...
