How to prepare flank steak with chimichurri?

Flank steak is a cut of beef that is extracted from the cow’s  abdomen. One of the most traditional ways to eat this cut is with chimichurri sauce, a delicacy that comes from Latin America. The texture and flavor is unique!

Flank steak and how to prepare it

A flank steak is characterized by an intense flavor and a tender texture, as long as the meat is properly prepared. As the flank steak is extracted from the abdomen of the beef, the cut is very lean, and  this means that, when it is not cooked properly, the result is a dish with tough meat without much flavor.

For flank steak to be delicious, it is necessary to marinate it for long periods of time. Marinating plays a key role in any flank steak recipe because it serves not only to flavor, but also to tenderize the meat. It is usually advisable to marinate the meat overnight in a refrigerator and then bring it to room temperature for grilling.

The cooking time varies depending on the temperature you use, but it will never be more than 10 minutes in total. Also, if you use a mallet to tenderize the meat, the time will be reduced considerably. Keep in mind that this cut is approximately 30 centimeters long and one centimeter thick. If you hit it with a mallet before cooking, the thickness will decrease and so will the cooking time.

Chimichurri sauce: a delight for the palate

Flank steak with chimichurri is nothing more than flank steak accompanied by a delicious chimichurri sauce. This sauce is characterized for having a very strong flavor and for being the star in many dishes in Argentina, Uruguay and Paraguay. It has a spicy taste and is perfect to accompany different beef cuts and even to marinate some fish.

The chimichurri sauce has no big secret: you just have to mix all the ingredients correctly, let it emulsify and then spread it over the flank steak. One of the tips from expert cooks is to prepare the sauce well in advance of cooking the steaks. They even recommend making it two or three days before grilling the steaks!

This is because chimichurri sauce tastes better after a few days when the ingredients have settled. The sauce should be mixed well and concentrated which is why it should not be  served immediately after its preparation. You should prepare the sauce and store it in an airtight container in the refrigerator. As you do not want the sauce to be cold when you serve it over the flank steak, take it out to reach room temperature when you remove the meat from the refrigerator; that is, two hours before cooking.
