Question: how to cook a marinated steak in a cast iron skillet?
Answer: Marinate in refrigerator for at least 2 hours, or up to 24 hours. Remove the steaks from the fridge and marinade 1 ½-2 hours before cooking, allowing them to come to room temperature on a cutting board. Set a large 12-inch cast iron skillet over high medium-heat, allowing it to heat up for 3-4 minutes.
