Tomahawk Steak Grill Temperature at a Glance
- Indirect/roast zone: 225-275°F
- Direct sear zone: 450-600°F+
- Pull from indirect at: 110-115°F internal
- Final internal temp after sear + rest (medium-rare): 125-130°F
A tomahawk is essentially an extra-thick, bone-in ribeye, and it’s almost always cooked with a reverse sear rather than a straight grill sear.
Why Reverse Sear Is the Best Method for a Tomahawk
A tomahawk’s thickness — often 2 inches or more — is exactly the problem with a straight, hot sear: by the time the center reaches medium-rare, the outside has usually gone well past a crust into burnt territory. Reverse searing solves this by bringing the whole steak up to temperature gently first (low, indirect heat), then finishing with a short, very hot sear that only needs to brown the surface, not cook the interior. The same logic applies to cowboy and other thick-cut ribeyes.
How to Reverse-Sear a Tomahawk Steak
Season and Rest
Season generously with kosher salt and coarse pepper — a tomahawk’s size means it can take a heavier hand than a smaller steak. Let it sit at room temperature (or dry brine, uncovered in the fridge, for a few hours beforehand) before cooking.
Smoke/Roast Low and Slow (225-275°F)
Set up your grill or smoker for indirect heat at 225-275°F. Place the tomahawk on the indirect side and let it cook gently, checking internal temperature periodically rather than flipping on a schedule.
Sear Hot to Finish (450-600°F+)
Once the steak hits 110-115°F internal, move it to the hot, direct-heat zone (or a screaming-hot cast-iron pan) and sear hard on all sides, including the edges, for 1-2 minutes per side until a deep crust forms.
Rest Before Carving
Let the tomahawk rest 10-15 minutes before carving off the bone and slicing — this cut holds a lot of heat, so it needs more rest time than a smaller steak.
How Long to Grill a Tomahawk by Size
Actual time depends heavily on the exact thickness and weight, and reverse-seared cuts should always be finished by internal temperature rather than the clock — but as a starting point:
- 2-inch tomahawk: Roughly 45-60 minutes on the indirect side to reach 110-115°F, plus a few minutes of searing.
- 4-inch-thick tomahawk: This is an unusually thick cut (closer to a full roast than a typical steak) — expect well over an hour on indirect heat, and check temperature frequently rather than trusting a time estimate at all.
- 3 lb tomahawk smoked at 225°F: Roughly 1.5-2 hours on the smoker to reach pull temperature, depending on exact thickness and how consistently your smoker holds 225°F.
Should You Sear at 400°F or 450°F?
For the sear stage of a reverse-seared tomahawk, go hotter than 400°F if your grill can manage it (if it won’t get there, see our gas grill troubleshooting guide) — 450°F and up gives a faster, deeper crust, which matters more here than on a straight-grilled steak because the interior is already close to done by the time you sear. A slower sear at 400°F risks pushing the center past your target before the crust catches up.
Tomahawk Doneness Temps
| Doneness | Pull From Indirect | Final After Sear + Rest |
|---|---|---|
| Rare | 100-105°F | 120-125°F |
| Medium-Rare | 110-115°F | 130-135°F |
| Medium | 120-125°F | 140-145°F |
FAQ
How long does a 2-inch tomahawk steak take to grill? Roughly 45-60 minutes on indirect heat at 225-275°F to reach pull temperature, plus a few minutes of hot searing — always confirm with a thermometer.
Should I grill steak at 400 or 450? For a tomahawk’s sear stage, aim for 450°F or hotter so the crust forms quickly without overcooking the already-warm interior.
How do I cook a 4-inch-thick tomahawk steak? Treat it more like a roast than a steak — reverse sear on indirect heat for well over an hour, checking internal temperature frequently, then sear hard to finish.
How long to smoke a 3 lb tomahawk steak at 225 degrees? Roughly 1.5-2 hours to reach pull temperature (110-115°F for medium- rare), depending on the steak’s exact thickness.
