The night before you plan to cook the steaks, pat dry with paper towels and put on a wire rack set inside a rimmed baking sheet. Season generously with salt and pepper and chill, uncovered, until about an hour before you want to cook your steaks. Pull steaks from the refrigerator and let sit on your counter at room temperature.
