Reverse Sear Tomahawk Steak — Cook Time & Temp Calculator

A tomahawk steak — a bone-in ribeye with the full long rib bone still attached — is almost purpose-built for the reverse sear method. These steaks typically run 2–2.5 inches thick and weigh 2–3 pounds; cooking them via traditional sear-first method produces a heavily overcooked exterior by the time the center reaches medium-rare. In a 250°F oven, a 2-inch tomahawk takes 60–90 minutes to reach the target pre-sear temperature, then sears dramatically in a ripping-hot cast iron or on a hot grill.

The long bone on a tomahawk doesn't affect cook time but does affect handling. Use tongs that grip the bone for flipping, and be careful — bone edges are sharp after cooking. Let the steak rest bone-side down on a cutting board so the meat doesn't touch the cutting surface.

Frequently Asked Questions

What is the reverse sear method?
Reverse searing flips the traditional order: instead of searing first then resting, you cook the steak low-and-slow in the oven first, then sear briefly over very high heat. This gives edge-to-edge even doneness and a better crust with no grey band.
What oven temperature for reverse sear?
Use 225–275°F (107–135°C). Lower temperatures give more control and a more uniform internal color. 250°F is the most popular balance point — hot enough to be practical, low enough for precision.
What internal temperature should I pull the steak at for the reverse sear?
Pull the steak from the oven 10–15°F below your final target. For medium rare (130°F final), pull at 115–120°F. The sear will add 5–10°F, bringing it to the perfect finish.
Does reverse sear work on thin steaks?
No — reverse sear is designed for steaks 1 inch or thicker. Thin steaks cook through too quickly in the oven before you can build the gradual temperature gradient that makes reverse sear effective.

Frequently Asked Questions

How long does a tomahawk steak take to reverse sear?
A 2-inch tomahawk: 60–90 minutes in a 250°F oven (to reach 90–100°F), then 2 minutes per side in a screaming-hot cast iron or directly over charcoal. A 2.5-inch tomahawk: 90–120 minutes in the oven. Total time: 1.5–2.5 hours. Use a probe thermometer — the long bone makes the thick section near the bone cook slower than the thinner edges.
Can I reverse sear a tomahawk on a grill?
Yes — the grill version is visually impressive. Set up indirect heat (one side on, one side off). Place the tomahawk over indirect heat at 250–275°F until 90–100°F internal, then move directly over the coals or high-heat burner for 2 minutes per side. If you have a charcoal grill, use the tomahawk's bone as a handle to safely move it over the fire.
How much does a tomahawk steak weigh and how many does it feed?
Tomahawk steaks typically weigh 2–3 pounds with the bone (1.5–2 lbs of edible meat without the bone). At 8 oz per serving for a steak dinner, a 2-pound tomahawk feeds 2–3 people. Most restaurants serve one tomahawk as a shared entrée for two, presented on a platter and carved tableside.
