How to Cook Flank Steak
Start by cutting the flank steak into four equal portions. This is a great way to serve an inexpensive steak dinner, and it cooks so quickly it’s perfect even on a busy weeknight!
Cast Iron Skillet Steak
For this recipe, use a good old-fashioned cast iron pan. Sear the seasoned flank steaks quickly on both sides, then transfer them to the oven for a very short amount of time to finish cooking. Finally, while the steaks are resting, whip up a delicious pan sauce that will take the steak from simple to restaurant style.
These steaks will cook very quickly, in just a matter of minutes depending on thickness.
Once the steaks have rested, slice against the grain before serving for a truly tender skillet flank steak. Spoon garlic butter sauce over steaks before serving.
