Cooking Instructions

  1. 1

    Preparation

    Remove the porterhouse steak from the refrigerator and let it sit at room temperature for about 30-60 minutes before cooking.

  2. 2

    Seasoning

    Pat the steak dry with paper towels. Generously season both sides with kosher salt and black pepper.

  3. 3

    Searing

    Heat a large cast-iron skillet or grill over high heat. Once hot, add the olive oil.

  4. 4

    Cooking the Steak

    Place the porterhouse steak in the skillet or on the grill. Cook for about 4-5 minutes on one side until a nice crust forms.

  5. 5

    Flipping the Steak

    Flip the steak and add the butter, garlic cloves, and rosemary to the pan. Cook for another 4-5 minutes for medium-rare, adjusting time for desired doneness.

  6. 6

    Basting

    Tilt the skillet and use a spoon to baste the steak with the melted butter and juices for extra flavor.

  7. 7

    Resting

    Remove the steak from the skillet and let it rest on a cutting board for about 10 minutes before slicing.

  8. 8

    Serving

    Slice the steak against the grain and serve immediately with your choice of sides.
