Learning the art of how to cook fillet steak depends upon how well you can prepare it. From the marination to the serving, everything needs to be just right.
- First, take your beef steak out of the fridge for at least half an hour and not more than 2 hours before cooking it.

- Take a heavy-based frying pan and place it over high heat. Add oil to cover the bottom of the frying pan. Now down the beef steaks when the pan is smoking hot, and don’t touch it for a few seconds.
- After frying for 2 to 3 minutes, it will develop a brown caramelized colour. Once the steak is golden-brown, turn down the temperature and flip the steaks. And keep cooking them to prevent burning.
Tip: Fillet steaks are thicker than any other steak like ribeye or sirloin. Usually, it takes some more time to cook them.
- Sear the steaks for a few more minutes and add butter, garlic, rosemary, and thyme to the pan. Now allow the butter to melt and baste it over the steak on both sides. Cook it for 3 to 4 minutes to get a medium-rare finish.
- Finally, let the steak rest for at least five minutes in a warm place to improve its juiciness and flavour, and then serve them on a plate with some side dishes.

If you want to prepare restaurant-quality fillet steaks, there are certain things that you need to know first.
Grass-fed vs Grain-fed Beef

And not to mention they are much richer and more flavoursome in taste. Grass-fed beef is also recognized for its dark red colour paired with ‘orangey’ coloured fat instead of pale white. This colouration comes from Vitamin-A-filled natural grass.
Ageing of The Fillet Steak
Some say wet-aged fillet steaks are the best, but according to some, dry-aged fillets give you the best taste and flavour. So, now what to choose, right?
According to the experts, steaks should be wet and dry-aged for about 21 days—which delivers the best quality in terms of taste and tenderness.
Fat Marbling
Marbling or white flecks is a type of fat found within the meat muscle that is formed inside the cut of the rib eye. When you cook the steaks—the marbled fat melts and delivers a juicy taste. Without this, your steaks taste dry and tasteless. It is one of the most tender cuts of meat available than any other steak.
