First of all you have to place a pan on the stove and heat it till it become very hot. Now place your ‚Äòflank steak‚Äô on this pan. Now you have to season it on both the sides. You can season it with salt and pepper. You have to ‚Äòsear‚Äô it thoroughly till it reaches a rich dark brown crust on the other side. Remember that you must not try to move the steak too much. Moving the steak may cause it to boil which is not required. Now turn over the steak on the pan. Allow it to heat for sometime. Now transfer the steak as soon as possible into an oven. That‚Äôs' it.
