The porterhouse is a delicious, two-part steak, including portions of both the tenderloin and the top loin. This is our favorite way to cook it; it produces a crusty brown exterior and an evenly cooked interior. (Note: This is also a smoky way to cook steak, so use your exhaust fan.)
2 2"-thick (28–36 oz.) porterhouse steaks
Salt and freshly ground black pepper
1. Set steaks out on a clean surface until they reach room temperature throughout, 1–2 hours. Preheat oven to 500°. Put a cast-iron skillet large enough to fit steaks comfortably into oven and heat for 20 minutes. Rub both sides of steaks with a little olive oil and generously season with salt and pepper.
2. Add steaks to hot skillet and cook in oven until well browned on bottom, 8 minutes. Turn steaks and cook in oven on second side, 5–6 minutes for rare, 7–8 minutes for medium rare. Remove steaks from skillet and set aside to rest for 5 minutes before serving.
