Grilled Chipotle Flank Steak: Spicy, Tender, Perfectly Cooked

Grilled flank steaksSometimes you want a big thick steak on a plate. But sometimes, you just want some solid, beefy flavor, and for that, you want a flank steak. Flank steak is a delicious, meaty cut that delivers big on taste while coming in short on price. And when it’s done properly, it’s almost as good to eat as any high-priced cut.

Today we’ll be going over a recipe for chipotle grilled flank steak that is based on one from The Sauce at All Things BBQ. This straightforward recipe demonstrates the strength of flank steak and gives you a delicious way to use your Thermapen® Mk4 (or since we’re talking instant-read thermometers, a ThermoPop®—on sale now!)

What is flank steak?

Flank steak comes from the rear-bottom portion of the steer’s belly. Its proximity to the legs means that it is a well-used muscle, and because of this level of movement, the flank steak tends to be very flavorful, and that flavor is one reason flank is so well loved.

Now, normally we would never cook such a well-exercised muscle like a steak (brisket steak is a non-starter), but the flank has a few features that allow us to use it in a way we wouldn’t use other tougher cuts of beef.

Flank steak is from the bottom rear of the steer's belly

One useful feature is its thickness, or, rather, its thinness. The flank is rarely much more than an inch thick when butchered and therefore doesn’t take long to cook through to the center. The speed of heat transfer that is possible with this cut means you don’t have to manage the cooking like you do with, say, a prime rib—cooking large cuts to medium-rare takes a long, slow approach. You can sear the outside quickly, cook it a bit longer and voilà, perfect flank steak.

 

Slicing flank steak

Another useful feature of the flank steak is its grain. Unlike other well-used muscles like brisket or chuck—which are made of multiple muscles with grains at odd angles to each other—flank has a simple, straight grain structure. That simple structure means that slicing it is no problem. The long-grain structure of the meat allows you to easily cut perpendicular to the grain for optimal tenderness.

Why cut perpendicularly? The muscle fibers in this meat are not tender, and if you try to chew long pieces of them they can be stringy. Cutting perpendicular allow you to get the shortest fibers, making your flank steak more enjoyable. And for the same reason, as you have probably already figured, it is important to cut the steak into slices that are the thinnest your knife skills can manage.Slice flank steak thinly and perpendicular to the grain

While this may seem a bit persnickety, the rewards are great. One flank steak yields positively stacks of thin, juicy strips of beef that can be piled on sandwiches, a hearty salad, tacos, or just piled on a plate next to some roasted potatoes.

Flank steak temperatures

I have repeatedly mentioned cooking this cut to medium-rare, and I mean it. If you like your steak medium-well, I recommend a different cut, because this thing will be tough at that temperature. For a rare flank steak your target temperature (Check it with a Thermapen Mk4 or a ThermoPop) is 120–130°F (49–54°C). For a dark-rosy medium-rare, shoot for a final temperature of 130–135°F (54–57°C).

You’ll get about 5–7°F (3–4°C) of carryover cooking on a flank steak after you remove it from the grill, so plan your pull temp accordingly.

  • Chipotle BBQ rub of your choice

Instructions

  • Trim your flank steak of any silver skin or excess fat. There is a membrane that runs through much of the center of the steak that you should leave be. Chasing it will destroy your steak. Trim your flank steak of silver skin and excess fat
  • Marinate/brine the flank steak in the refrigerator for at least1 hour/pound of meat. This will help to soften the tough fibers before cooking by dissolving some of the proteins that will otherwise coil up and toughen.Marinate the flank steak, or brine it!
  • Heat your grill to high heat.
  • Remove the steak from the marinade/brine and shake of excess.
  • Coat the flank steak generously on both sides with chipotle rub.
  • Let the rub “soak” for a few minutes to adhere to the meat better.Apply generous amounts of rub to the steak and let it sit for a few minutes to adhere
  • Oil the grill grates well.
  • Place the steak on the grill over direct heat and cook, rotating half turn after about 3 minutes to get a nice cross-hatch pattern. (Note: a lot of your rub may stick to the grill. If this happens, move the meat to another part of the hot grates when you rotate so that you have good contact with the grill.)Grilling flank steak
  • When the first side is well seared, flip the steak.
  • Cook on the second side, checking the temperature every few minutes with your Thermapen Mk4 or ThermoPop.
  • When the internal temperature reaches 125°F (52°C), pull it from heat and allow it to rest for 5 minutes.Cook flank steak to 125°F
  • Slice the steak very thinly across the grain and serve in any of a thousand ways.Slice the flank steak and serve
