Grilled Flank Steak with Salsa Verde is an easy weeknight meal and also perfect for entertaining! Packed with punchy flavours this Salsa Verde also works well with fish, chicken or vegetables. I even had some on my eggs this morning and it was delicious! Try it. You're gonna love it.
I couldn't decide between an Italian style salsa verde and Chimichurri so I did some research. What the heck is the difference anyway? There are some similar ingredients in both such as olive oil, garlic, vinegar or lemon juice and some mixture of fresh herbs. Chimichurri usually has oregano and some kind of chili pepper. Salsa Verde typically has anchovy, capers, mustard and sometimes pickles. There is a mind boggling number of variations. I liked the idea of combining some elements of both. I called it a Salsa Verde because I think it leans more towards that side. Regardless of what you want to call it, it's delicious!
This sauce is used as both a marinade and a finishing flavour punch. I leave out the pickles and capers, use half the salsa verde to marinate the flank steak and then add the pickles and capers to the remaining sauce. You can make this sauce in a food processor or with a hand blender but I don't recommend it. When you chop everything by hand the salsa verde has such a nice look and texture.
What is flank steak?
Flank steak is a very flavourful, lean and inexpensive cut of beef. It comes from the lower abdominal area of the cow. Because it is so lean it is best marinated and cooked over high heat for a short period of time. It's one of my favourite cuts of beef because it's so flavourful but it can be tough if not treated right. Marinating, cooking high and fast, and slicing it thinly across the grain are all very important steps to creating a delicious grilled flank steak.
Don't be overwhelmed by the long list of ingredients. You can mix things up as much as you like. Omit some of the herbs or replace them with ones you like better, leave out anything you don't have or like. As long as you have the base of olive oil, vinegar, garlic and fresh herbs it will be delicious! Have fun and play around with it. The longer you can marinate the steak the better so you can start it the day before. Or if you don't have enough time a minimum of 3 hours works too.
Season the flank steak generously with salt and pepper on both sides and cook on a hot grill for approximately 10 minutes, flipping half way through. You don't want to over cook this cut. Medium rare is ideal with an internal temperature of 130°F. If you don't have a meat thermometer I highly recommend investing in one like this Thermoworks Thermapen.
When the flank steak is done remove it from the grill and cover loosely with foil. Let it sit for 10 minutes before slicing. This allows the juices to be reabsorbed by the steak instead of seeping out when you slice it.
