Sear each side of the steak in the pan for 2 â 5 minutes; peek underneath to know when to flip. You want it brown but not black (i.e., burnt). If you like your steak rare to medium rare, you can often stop here. Just check the internal temperature of the steak with your meat thermometer (see above). If you like your steak medium to well done, put it in the oven on a small rack over a baking sheet lined with tinfoil to roast for another 5-15 minutes. (Again, with the meat thermometer, youâll know exactly when to take it out.)
The next step is to put the flank steak on the grill. Itâs recommended that you then grill the steak for approximately 10 minutes over coals that are medium-hot. While a grilling time of 10 minutes will give you a medium-rare steak, you may allow it to grill for a bit longer until the beef reaches the desired doneness.However long you decide to grill your flank steak, remember to turn it over as soon as the grilling time is halfway done.hile a grilling time of 10 minutes will give you a medium-rare steak, you may allow it to grill for a bit longer until the beef reaches the desired doneness.
