Ingredients

  • 1 1/2 pounds porterhouse steak  about 1-inch (2.5cm) thick*
  • 2 tablespoons olive oil divided**
  • 1 teaspoon coarse salt  or to taste
  • 1 teaspoon black pepper  freshly ground, or to taste
  • 2 cloves garlic  minced (2 teaspoons)
  • 1 tablespoon  unsalted butter
  • fresh herbs such as rosemary and thyme, optional

Instructions

  • Remove the porterhouse steak from refrigerator 30-60 minutes before cooking to let it reach room temperature. This promotes even cooking for the juiciest steak.
  • Position the oven rack in the middle and preheat oven to 425°F (218°C).
  • Place a large cast-iron skillet over high heat and allow to heat for 5 minutes until extremely hot. (You can also place in the preheated oven for 15 minutes.)
  • Pat dry the steak with paper towels to remove excess moisture that could interfere with searing.
  • Rub 1 tablespoon of olive oil on both sides.
  • Season both sides with salt and pepper.
  • Add the remaining 1 tablespoon oil to the pan and swirl to coat.
  • Carefully place the porterhouse in the pan using kitchen tongs, laying it away from you to avoid splatter.
  • Sear the first side for 2 minutes.
  • Flip using kitchen tongs and sear the other side for 2 minutes.
  • Add garlic, butter and fresh herbs to the pan. Then immediately transfer the skillet to the oven.
  • Bake without flipping the steak according to your desired doneness: 1-2 minutes for rare, 2-3 minutes for medium-rare, 3-4 minutes for medium, and 5-6 minutes for well-done. Check doneness using an instant-read thermometer***.
  • Remove steak to a plate or cutting board covered with aluminum foil to rest for 5 minutes so the juices can retreat back into the meat.
  • To serve, cut the meat away from the bone and slice across the grain into strips.

Notes

  • *Porterhouse steaks that are at least 1-inch (2.5cm) thick are juicier and less likely to be overcooked.
  • ** Regular refined olive oil works best, as it has a higher smoke point than extra virgin olive oil.
  • ***Insert the thermometer into the strip section about 1-inch from the bone: 120°F/49°C is rare, 130°F/54°C is medium-rare, 140°F/60°C is medium, 150°F/66°C is medium-well and 160°F/71°C is well-done. (Note that the temperature will continue rise several degrees more after cooking.) For thicker porterhouse steaks, you'll need 2-3 minutes of extra baking time per additional 1/2-inch.
