How to prepare stuffed flank steak

Flank steak is a cut of beef that is removed from the diaphragm area. The flank can be either inside or outside and is characterised by a thick membrane that must be removed before cooking. Stuffed flank steak is one of the many styles in which you can prepare this delicious cut.

What is flank steak and how do you make it?

This cut is very popular on the grills of Argentina and Mexico; in the first country it is usually prepared with chimichurri sauce, while in the second, as arrachera or fajitas. Flank steak is usually grilled or barbecued, whole or in steaks. It is a meat that is characterised by not being particularly tender and soft, and has a slightly tough texture. For this reason, its marinating process has to be quite long, so that the meat can soften.

On the other hand, to prevent the meat from becoming tough, it is also important to remove the membrane that covers it. This pre-cleaning can be done by yourself or at home, or you can ask the butcher to do it for you. 

Preparing flank steak is an art in itself. It takes a long time to prepare, as the marinating time must be at least six hours. Cooking is not easy either, as a flank steak can take up to an hour on the grill and over a very low, indirect heat, so that the meat can stay juicy. If you want something quick, then the fat should be removed from the cut, but even so, it is best to allow plenty of time to create a delicious recipe.

You may be surprised to know that flank steak can also be stuffed. If you want some variety and to offer something different to your guests and surprise them with a unique recipe, this style is just what you need.
