How To Cook Tomahawk Steak In Oven

ByLily

Oven-roasting a tomahawk steak means managing a long bone and uneven thickness with low heat and a final sear. If you want to know how to cook tomahawk steak in oven, the method is simpler than the size suggests. You just need the right temperature, a good thermometer, and a little patience.

This cut is basically a ribeye with a very long bone attached. That bone looks impressive, but it also slows down cooking and makes the meat cook unevenly. The oven does most of the work here. Your job is to control the heat and finish with a hard sear.

What You Need Before You Start

Gather your tools first. A tomahawk is heavy and awkward, so a little prep saves trouble later.

  • One tomahawk steak, about 2 to 3 pounds and 1.5 to 2 inches thick
  • Kosher salt and coarse black pepper
  • A wire rack set inside a sheet pan
  • An instant-read meat thermometer
  • A cast iron skillet or heavy oven-safe pan
  • High smoke point oil, like avocado or canola
  • Butter, garlic cloves, and fresh thyme (optional)

Let the steak sit at room temperature for 30 to 45 minutes before cooking. A cold center cooks slower and throws off your timing.

How To Cook Tomahawk Steak In Oven

This is the core method. Low oven heat brings the whole steak up to temperature gently, then a hot pan gives you the crust.

Step 1: Season The Steak Well

Pat the surface dry with paper towels. Moisture steams the meat and stops browning.

Season all sides generously with salt and pepper. Use more salt than you think you need. The steak is thick, so the seasoning has to reach a lot of meat.

Step 2: Preheat The Oven Low

Set your oven to 250°F (120°C). Place a rack in the middle position.

Low heat is the key here. A hot oven would cook the outside of the steak long before the inside is ready. The bone also acts like a heat sink, so slow and steady works best.

Step 3: Roast On A Wire Rack

  1. Put the steak on the wire rack over the sheet pan.
  2. Slide it into the oven.
  3. Roast until the internal temperature hits 115°F to 120°F for medium rare.

This usually takes 45 to 70 minutes, depending on thickness and your oven. Start checking at 40 minutes. Do not rely on time alone. Use the thermometer.

Target Internal Temperatures

  • Rare: 110°F to 115°F
  • Medium rare: 115°F to 120°F
  • Medium: 125°F to 130°F
  • Medium well: 135°F to 140°F

Remember, the temperature will rise another 5 to 10 degrees while the steak rests.

Step 4: Rest The Steak Briefly

Take the steak out and let it rest for 10 minutes. Cover it loosely with foil. This step lets the juices settle and keeps the meat from drying out during the sear.

Step 5: Sear In A Hot Pan

Heat your cast iron skillet over high heat until it is smoking slightly. Add a thin layer of oil.

  1. Place the steak in the pan. It should sizzle loud right away.
  2. Sear for 60 to 90 seconds per side.
  3. Hold the steak with tongs to sear the edges and the fat cap.
  4. Add butter, garlic, and thyme in the last 30 seconds. Spoon the melted butter over the steak.

Keep the pan hot but not so hot that the butter burns. If it turns black, lower the heat.

Step 6: Check Temperature And Serve

After searing, the internal temperature should be around 125°F to 130°F for medium rare. If it is still low, put the pan in the oven for 5 minutes.

Let the steak rest for 5 to 10 minutes on a cutting board. Then slice against the grain, away from the bone. Cut thick slices, about half an inch.

Common Mistakes To Avoid

  • Cooking from a cold start. Let the steak sit out first.
  • Skipping the thermometer. Guessing leads to overcooked meat.
  • Searing before roasting. This can burn the crust while the center stays raw.
  • Crowding the pan. A crowded pan steams the steak instead of searing it.
  • Cutting too soon. Resting keeps the juices in the meat, not on the board.

Tips For A Better Result

Dry brine the steak the night before. Salt it, leave it uncovered in the fridge, and let the surface dry out. This gives you a better crust.

Use a cast iron pan if you can. It holds heat better than nonstick and gives a deeper sear.

If your steak is very thick, add a few extra minutes in the oven. Just check the temperature every 5 minutes near the end.

Let the steak rest on a warm plate, not a cold one. A cold plate pulls heat out fast.

Serving Ideas

Slice the steak and serve it on a warm platter. Pair it with roasted potatoes, grilled asparagus, or a simple green salad.

A tomahawk feeds two to three people, depending on appetite. If you have leftovers, store them in the fridge for up to three days. Reheat gently in a low oven so the meat does not dry out.

Final Thoughts

The oven method works because it treats the tomahawk like the thick, uneven cut it is. Low heat cooks the center. A hot pan builds the crust. Control those two stages and you get a steak that is pink inside and deeply browned outside.

Practice the timing once, note your oven’s behavior, and the next tomahawk will be even easier.
