A well known and beloved dish in Tex-Mex and Mexican cuisine, steak fajitas ooze mouth watering flavour and make for a truly delicious meal full of meat, veg and delicious tastes.

Over the years, fajita wrap ingredients have changed and developed to suit different palates and meals, with the original fajita consisting of a cut of beef steak called the skirt steak.

While there are multiple fajita recipes out there for you to follow, today we’ll be showing you a steak fajitas recipe made with sirloin steak for optimum steak flavour and incredible lean properties.


Choosing your cut of sirloin steak is an important step when it comes to choosing the right steak for you. In this recipe, we’ll be using the Black Label Argentine Beef sirloin which delivers aromatic and rich flavours ideal for fajitas.

For a really premium quality sirloin cut, take a look at Tom Hixson of Smithfield’s range of Wagyu sirloin.


To prepare your steak, trim all visible fat and cut into thin strips small enough to fit into a wrap.

While this isn’t a necessary step in preparing your steak for cooking, marinating your steak in a steak fajitas marinade will add extra flavours to your steak, however will make the process considerably longer. You can use a steak marinade of your choice when marinating, and should marinate from anywhere between 2 and 8 hours. 

Add this time to your preparation time and total time if marinating.
