Searing the steak involves cooking it over direct, high heat. It will seal in the juices and flavors while forming a caramelized crust around the meat.

Cook each side of the steak for 3–4 minutes until it forms a golden-brown crust.

4. Reduce to Medium Heat

Once the tomahawk steak has been seared over high heat, the heat should be turned down to medium to make sure it is cooked all the way through.

It will avoid overcooking the steak and ensure it is cooked evenly throughout.

When the steak’s internal temperature reaches the right level of doneness, put it on the grill grate and cook for 4–6 minutes on each side.

Let it rest for a few minutes so the juices can spread evenly through the meat; this will result in a tender, juicy, and flavorful tomahawk steak that’s sure to impress.
