Cast-Iron Cowboy Steak

Step 1 -Preheat the grill to high heat (about 400-450 degrees F).

Step 2 -Place a 12-inch cast-iron skillet on the preheating grill, cover the grill with the lid, and let the pan sit, about 15 minutes.

Step 3 -Generously and evenly sprinkle both sides of the steak with the salt and the pepper.

Step 4 -Add the oil to the hot skillet. Note: When the skillet begins to smoke once the oil is added, that means it is hot enough.

Step 5 -Use tongs to carefully place the seasoned steak in the oil and cook until it is brown and crusty on the bottom, about 10 minutes.

Step 6 -Use the tongs to carefully flip the steak onto the fatty edge and cook, while holding the steak upright with the tongs, about 2 minutes.

Step 7 -Use the tongs to flip the steak onto the uncooked side. Close the grill's lid and cook until the meat reaches an internal temperature of 130 degrees F for medium-rare doneness, about 8-10 minutes.

Step 8 -Add the butter, the rosemary sprigs, and the garlic to the skillet and cook, until the butter foams, about 2-3 minutes.

Step 9 -While wearing an oven mitt, carefully tilt the skillet and spoon the herb butter mixture onto the steak, about 20 times.

Step 10 -Transfer the steak and the herbs to a cutting board and let them rest until the meat reaches an internal temperature of 135 degrees F for medium-rare doneness, about 5-10 minutes.

Step 11 -Slice and serve.
