Prep: One hour before cooking, pull the steak from the fridge. Pat it dry with paper towels, then thoroughly rub with the seasonings. Allow the steak to rest at room temperature to take the chill off.
Prepare your grill for cooking over direct, high heat. Clean and oil your grill grate.
Pre-heat your oven to 275 degrees Fahrenheit.
Place the seasoned tomahawk steak directly on the grates in your direct heat zone. Sear on each side for 4-5 minutes, until a nice crust begins to form and the steak releases easily from the grates when flipping.
With long-handled heat-safe tongs, quickly sear each of the narrower edges of the steak for 20-30 seconds, then remove from the grill.
Transfer to a large casserole dish or rimmed baking tray, and place in the oven to roast. It took me about 45 minutes to get my steak to 130 degrees Fahrenheit. My goal was medium rare, so I pulled it and let it rest once it hit this temp. For rare, pull your steak at 125 F, medium rare 130 F, 140 F medium.
Remove the steak from the oven. Let the steak rest in the pan for 10-15 minutes, then transfer to a cutting board.
Slice against the grain for best results. Serve warm!
Notes
Note: I used my gas grill, but of course you can use your charcoal grill! Grill directly over the hot coals, aiming to sear your steak at a temp somewhere in the 500-600 degree Fahrenheit range. AKA, HOT! The type of grill you use does not matter as much your ability to maintain the right temperatures!Your cooking time will vary depending on the exact size of your steak! Your instant read thermometer is your friend with this recipe. Instead of the oven, feel free to finish roasting your steak in indirect heat on your grill or smoker. Maintain a temp around 250-275 degrees Fahrenheit and expect it to take 45-60 minutes to reach your desired temp.
