Cooking Instructions

  1. 1

    Preparation

    Remove the filet mignon from the refrigerator and let it sit at room temperature for about 30 minutes. This helps the meat cook evenly.

  2. 2

    Season the Steak

    Rub the filet mignon with olive oil, then season generously with salt, black pepper, and garlic powder on both sides.

  3. 3

    Preheat the Pan

    Heat a cast-iron skillet over medium-high heat for about 5 minutes until hot.

  4. 4

    Sear the Steak

    Place the filet mignon in the hot skillet and sear for 4-5 minutes on one side without moving it.

  5. 5

    Flip and Add Flavor

    Flip the steak and add butter and rosemary to the pan. Cook for an additional 4-5 minutes for medium-rare, spooning the melted butter over the steak continuously.

  6. 6

    Rest the Steak

    Remove the steak from the skillet and let it rest on a cutting board for 5-10 minutes before slicing. This allows the juices to redistribute.

  7. 7

    Serve

    Slice the filet mignon and serve with your choice of sides. Enjoy your king-size filet mignon!
