Method

Preparation

  1. 1

    Dry Aging the Steak

    Wrap the Kansas City Strip Steak in cheesecloth and place it on a wire rack in the refrigerator for 35 days. Ensure that the temperature is consistently around 34°F (1°C) to prevent spoilage.

  2. 2

    Seasoning the Steak

    After 35 days of aging, remove the steak from the refrigerator, unwrap it, and trim off any dried edges. Generously season both sides with kosher salt and black pepper, allowing it to sit at room temperature for about 30 minutes.

  3. 3

    Cooking the Steak

    Heat a cast-iron skillet over high heat and add olive oil. Once the oil is shimmering, add the steak to the skillet. Sear for 3-4 minutes on each side for medium-rare, adjusting the time based on your desired doneness.

  4. 4

    Adding Aromatics

    During the last minute of cooking, add crushed garlic cloves and fresh rosemary to the skillet. Baste the steak with the oil and aromatics for extra flavor.

  5. 5

    Resting the Steak

    Remove the steak from the skillet and let it rest on a cutting board for 10 minutes before slicing. This allows the juices to redistribute.

  6. 6

    Serving

    Slice the steak against the grain and serve immediately, optionally garnished with extra rosemary or a sprinkle of sea salt.
