Flank steak is delicious and packs a very beefy flavor even compared to other cuts, it is also pretty lean. Flank and skirt steak are from a similar part of the beef, though they perform different jobs. Flank and skirt steak differ in the orientation of the muscle fibers and the amount of connective tissue and fat; flank is long and lean while skirt tends to have a webbed appearance with more fat to trim off.

Flank and skirt steak are interchangeable in most recipes, I typically go for a flank steak because there is less to trim away and its easier to find because my local rancher tends to sell out of skirt steak first simply due to its popularity. With both it’s imperative to cook and cut them correctly or you will have a disappointingly tough piece of meat on your hands, both are ideal for medium-rare to medium-well cooking preferences.

Flank steak is best cooked one of two ways; long and low or fast and hot. I don’t typically have the attention span for a fast sear and I like that I can prepare my side dishes while the steak comes to temperature in a low oven or sous vide. This recipe utilizes the former in what is commonly referred to as reverse sear; the seasoned steak is cooked to desired temperature in a low oven, then grilled or seared in a hot pan. It’s a great way to meal prep too as you can pre-cook the protein ahead of time and do the sear step when you’re ready to eat it.
