how long do i cook a steak in the oven
1 Preheat the oven to 275 degrees. 2  Season the steaks with sea salt and fresh-cracked black pepper. 3  Place steak on a rack placed over a rimmed baking sheet and put in the preheated oven.  Cook the steaks in the oven for 40 to 45 minutes. The steak will still look fairly uncooked when you remove it from the oven.
