Depending on what cut you get and how thick it is will alter the cooking time. For most cuts, you'll want to cook 4-6 minutes per side, depending on what level of steak you want. If you're wondering how to cook thin steak, we only want to cook it in a pan (not the oven!) and reduce the cooking time. For medium rare, you'll want to cook your thin steak for about 3 minutes on each side.
