Cooking a steak in the oven like a chef is easy with a cast iron pan, and nothing else browns and seals in the juices so well.
Preheat your oven to at least 205 degrees C (500 F). Seasoned cast iron has no issues with synthetic coatings or plastic handles and heat limits!
Use good quality meat cut into a thick steak. Pat dry the steak with a paper towel then rub it all over with oil (use oil with a high smoke point, not olive oil) and sprinkle liberally with salt and pepper.
Pre-heat your cast iron pan on the stove on medium heat. Get it smoking hot then drop in your steak and cook it for exactly 2 minutes before turning it over and cooking for two minutes on the other side. Then put the pan in the oven for a few minutes depending on how well done you like your steak.
Carefully remove hot pan from oven using an oven mitt or towel, and transfer steak to another platter and let rest covered with aluminum foil.
Interesting all-oven alternative: pre-heat your pan in the oven, remove to sear steak for 30 seconds each side, then return to oven to finish baking. Cast iron has such a strong ability to hold heat that it will barely cool during the searing process!
Tip: after removing your pan from the oven, leave the mitt or towel over the handle to remind you it stays hot for some time!
