Steak and Seasoning

Method

Cooking Instructions

  1. 1

    Prepare the Steak

    Take the Porterhouse steak out of the refrigerator and let it sit at room temperature for about 30 minutes before cooking. This ensures even cooking.

  2. 2

    Season the Steak

    Generously season both sides of the steak with kosher salt and freshly ground black pepper. Make sure to rub the seasoning into the meat.

  3. 3

    Preheat the Pan

    In a large cast-iron skillet or grill pan, heat the olive oil over high heat until it shimmers.

  4. 4

    Sear the Steak

    Once the pan is hot, carefully place the steak in the skillet. Sear for about 4-5 minutes on one side without moving it.

  5. 5

    Flip and Add Aromatics

    Flip the steak using tongs, and add the fresh rosemary and garlic cloves to the pan. Sear the other side for another 4-5 minutes for medium-rare doneness.

  6. 6

    Check for Doneness

    Use a meat thermometer to check the internal temperature. For medium-rare, it should read 130°F (54°C). Adjust cooking time to reach desired doneness.

  7. 7

    Rest the Steak

    Remove the steak from the pan and place it on a cutting board. Tent with aluminum foil and let it rest for 10 minutes before slicing.

  8. 8

    Serve

    Slice the steak against the grain and serve with the pan juices drizzled over the top.
