Cooking Instructions

  1. 1

    Prepare the Steak

    Remove the prime flat iron steak from the refrigerator and let it sit at room temperature for 30 minutes before cooking. This helps the steak cook more evenly.

  2. 2

    Season the Steak

    In a small bowl, mix together the garlic powder, onion powder, salt, and black pepper. Rub the mixture evenly over both sides of the steak.

  3. 3

    Sear the Steak

    Heat a large cast iron skillet or grill pan over medium-high heat. Once hot, add the olive oil and swirl to coat the pan. Place the steak in the pan and sear for 4-5 minutes without moving it, allowing a crust to form.

  4. 4

    Flip the Steak

    Carefully flip the steak using tongs. Add the butter and fresh rosemary to the pan. As the butter melts, spoon it over the steak for additional flavor. Cook for another 4-5 minutes for medium-rare doneness.

  5. 5

    Check Doneness

    Use a meat thermometer to check the internal temperature. For medium-rare, it should read 130-135°F (54-57°C). Adjust cooking time according to your preferred doneness.

  6. 6

    Rest the Steak

    Remove the steak from the skillet and place it on a cutting board. Tent it loosely with foil and let it rest for 5-10 minutes. This allows the juices to redistribute.

  7. 7

    Slice and Serve

    Slice the steak against the grain and serve immediately. Enjoy your prime flat iron steak!
