Reverse Sear Tomahawk Steak: The Complete Australian Guide

There is something about a tomahawk steak that stops people in their tracks. That long bone, the thick slab of marbled beef, the sheer size of it sitting on a plate. It looks incredible, but for a lot of home cooks, it also looks terrifying. What if you char the outside before the middle is even warm? What if you spend serious money on a premium cut and end up with something tough and disappointing?

Here is the good news: the reverse sear tomahawk steak method was practically invented for exactly this situation. By gently bringing the steak up to temperature in your oven or smoker first, then hitting it with a screaming-hot sear at the end, you get edge-to-edge perfection every single time. The tomahawk's extreme thickness, the very thing that makes it so tricky to cook conventionally, actually works in your favour here.

In this guide, you will learn everything from choosing the right cut at your local Australian butcher, to exact temperatures in Celsius, seasoning tips, common mistakes to avoid, and how to carve and serve it like a pro. Let's get into it.

Why the Reverse Sear Is Perfect for Tomahawk Steak

A tomahawk steak is essentially a ribeye with a long, frenched rib bone still attached, typically 4–6 cm thick and weighing between 800 g and 1.2 kg. It is one of the most visually dramatic cuts you will find at an Australian butcher, and that sheer size is exactly what makes it so tricky to cook the conventional way.

Throw a tomahawk straight over high heat and you are racing against physics. The outside chars and colours beautifully while the thick centre is still cold and raw. By the time that centre finally reaches a safe eating temperature, the outer layers are grey, tough and overcooked. On a cut this generous, that is an expensive mistake.

The reverse sear solves this problem by flipping the order of operations. Instead of searing first and finishing in the oven, you do the opposite: cook the steak low and slow first, bringing the internal temperature up gradually and evenly, then apply ripping-hot heat at the very end to build the crust. The crust is where the real flavour lives, and the reverse sear gives you the best possible surface to work with.

Here is the reframe that makes this method so satisfying: the tomahawk's extreme thickness, the very thing that makes conventional grilling a gamble, becomes your advantage with reverse sear. All that mass absorbs gentle heat evenly and holds its temperature steadily, giving you far more control than a thinner cut ever could.

This guide walks you through everything you need to cook a tomahawk with confidence: choosing the right heat source (oven, smoker or kettle grill), exact temperatures in Celsius, a timing chart based on steak thickness, a seasoning approach built for bold beef, and how to carve and serve it properly once it comes off the heat.

How to Choose and Source a Quality Tomahawk in Australia

Before you fire up the oven, you need the right piece of meat. A poorly chosen tomahawk will fight you every step of the way, so it's worth getting this part right.

What to Look for at the Butcher

Three things matter most when you're standing at the counter.

Marbling is the fine white fat running through the muscle, not the thick fat cap around the edge. Good marbling looks like a frost pattern through the red meat. More of it means more flavour, more juiciness and a more forgiving cook.

Bone length should be at least 20 cm. Shorter than that and it stops being a tomahawk and starts being a glorified ribeye.

Thickness is the most important number. You need at least 4 cm to make reverse sear worthwhile. Thinner than that and the steak cooks through too quickly in the low-heat phase to benefit from the technique.

Understanding MSA Grading

Look for the Meat Standards Australia (MSA) logo when buying. MSA grades beef across over 1.8 million consumer taste tests into three tiers: 3-star (everyday), 4-star (better than everyday) and 5-star (premium). Each grade factors in marbling score among other carcass attributes. For a tomahawk, aim for 4-star or above.

Where to Source a Good Tomahawk

Your best options are independent butchers, specialty online meat retailers shipping nationally, and farmers markets across WA and other states. (Finding good butchers rewards word of mouth and local knowledge, much as we cover in our guide to sourcing quality cuts.) Major supermarket chains rarely carry bone-in tomahawks at the quality this technique deserves.

Thickness Beats Weight Every Time

Don't fixate on price per kilogram. A 1 kg tomahawk at 3 cm thick will cook significantly faster than a 900 g one at 5 cm thick. Always ask the butcher the actual thickness before you buy. That number drives your timing, not the weight.

Fresh vs Frozen

Fresh is ideal, but a well-frozen tomahawk from a reputable supplier is perfectly fine. The non-negotiable is complete thawing: move it to the fridge 24 to 48 hours before cooking. Cooking from partially frozen ruins the low-heat phase and makes accurate temperature readings impossible.

Equipment You Need to Reverse Sear a Tomahawk

Once you've sourced your tomahawk, getting the right equipment together makes the whole cook far less stressful. The good news is that you probably own most of what you need already.

A meat thermometer is the single most important piece of equipment you can own for this cook. Reverse searing is a temperature-driven technique, not a time-driven one. Timings vary based on your steak's exact thickness, your oven's calibration and the weather outside. A quality instant-read thermometer or a leave-in probe thermometer removes all of that guesswork. Check the internal temperature, not the clock.

Heat Source for the Low-and-Slow Phase

You have three solid options:

• Kitchen oven: The most accessible choice. Consistent, controllable and weather-proof. No smoke flavour, but it does the job reliably.

• Smoker (offset, pellet or kettle with a lid): The premium option. A smoker running at low heat adds flavour complexity that genuinely suits the tomahawk's bold, fatty profile. If you have one, use it.

• Covered charcoal or gas BBQ set up for indirect cooking: A practical middle ground for most Australian backyards. Coals or burners on one side, steak on the other, lid on.

If you want to know more about configuring your setup, this equipment you will need overview is a useful reference for indirect cooking arrangements.

Heat Source for the Sear

A charcoal or gas grill cranked to maximum is the natural Australian solution here. It also solves a practical problem: finding an indoor pan large enough for a full tomahawk is genuinely difficult. A large cast iron skillet works indoors, but it demands a powerful stove and good ventilation.

Supporting Equipment

If using the oven for the low-heat phase, a wire rack set inside a rimmed baking tray is essential. It allows hot air to circulate around the entire steak and catches drippings neatly.

For everything else, keep these within reach: long-handled tongs, heat-resistant gloves, a large cutting board and a sharp carving knife. At this scale, they go from optional to genuinely necessary.

Seasoning a Tomahawk Steak for Maximum Flavour

With your equipment sorted, it's time to think about seasoning, and this is where the tomahawk genuinely rewards boldness.

The tomahawk is a richly marbled, fatty cut with an intense beefy flavour. Unlike leaner steaks where heavy seasoning can easily overpower the meat, a tomahawk can take an assertive hand. In fact, it benefits from one. The fat, the thickness and the bone all contribute to a flavour profile that needs seasoning to match it, not shy away from it.

Dry Brining: The Step That Changes Everything

The best move you can make is to season your tomahawk well before it hits any heat. Apply a generous, even coat of seasoning to all surfaces, then leave it uncovered in the fridge for at least one hour, and ideally overnight.

Here's what's happening: the salt draws moisture to the surface of the meat, where it dissolves and forms a thin brine. That brine is then slowly reabsorbed back into the muscle, seasoning the meat from within rather than just coating the outside. The surface also dries out during this process, which is exactly what you want for maximum crust development during the sear.

What to Season With

Stoneville BBQ's Pindan Ironstone is a natural fit here. It's a bold steak seasoning built specifically for cuts like this, with a mineral-forward, WA-inspired flavour profile that complements the tomahawk's richness without masking the beef. Apply it generously across every surface, including the edges.

If you prefer a more traditional approach, a classic SPG base (salt, pepper, garlic) works beautifully on beef this flavourful. Stoneville's The Bark Whisperer is a Texas-style SPG blend that delivers exactly that: clean, classic beef flavour with nothing to get in the way.

What to Avoid

Skip wet marinades entirely. The extra moisture they leave on the surface actively works against crust formation during the sear, which defeats the purpose of the method. A small drizzle of oil just before searing is fine if you like, but with a well-marbled tomahawk it isn't necessary.

The Low-Heat Phase: Temperatures, Timing and What to Watch For

Once your steak is seasoned and resting, it's time to get the low-heat phase right. This is where the reverse sear earns its reputation.

Set your oven or indirect cooker to 110–120°C (230–250°F). That gentle heat is the whole point. Rather than blasting the outside while the centre struggles to catch up, this low temperature brings the internal temp up gradually and evenly from edge to edge. With a cut as thick as a tomahawk, that control is everything.

Pull Temperature, Not Time, Is Your Target

For medium-rare, pull the steak when the internal temperature reaches 46–49°C (115–120°F). For medium, aim for 52–54°C (125–130°F). These temps feel low, but remember: the sear and a rest period will push the final temperature higher.

A fixed time will not save you if your cooker runs hot or cold. Your thermometer is the only reliable guide. The same principle applies when cooking something like pulled pork, where hitting the right internal temperature is everything. Steak is no different.

Use this as a rough timing guide at 110–120°C:

These are starting points, not guarantees. Equipment calibration, ambient temperature and the steak's starting temp all affect the outcome.

The Smoker Advantage

If you have access to a smoker, use it for this phase. Running it at 110–120°C with Australian hardwood such as ironbark or red gum (or post oak if that's what you have) introduces a subtle smoke ring and a flavour layer that pairs beautifully with the bold, mineral character of Pindan Ironstone.

Practical Tips for This Phase

• Place the steak fat-cap up on the wire rack so the fat bastes the meat as it renders

• Resist opening the oven or smoker unnecessarily; every peek drops the temperature

• Start checking internal temp at the low end of the timing estimate to avoid overshooting your pull target before the sear

How to Sear a Tomahawk Steak for a Perfect Crust

Once your steak hits that pull temperature, get your sear station ready before you bring it inside. This is where the magic happens.

Why the crust will be exceptional

Here is the quiet advantage of reverse sear that most cooks miss: by the time your tomahawk comes off the low heat, its surface is significantly drier than a raw steak pulled straight from the fridge. That dry surface means the Maillard reaction, the browning process that creates crust, colour and flavour, kicks in faster and more evenly the moment the meat hits high heat. Less moisture to burn off means more browning, sooner. If you want to understand the full chemistry of why a dry surface produces better crust, the science behind how a rub creates bark is worth a read.

Get the heat genuinely ripping

Target grill grate or cast iron surface temperature: 260–290°C (500–550°F) minimum. If you do not have a surface thermometer, use the hand test. Hold your open palm 5 cm above the grate. If you can hold it there longer than 1–2 seconds, the surface is not hot enough. Give it more time. A lukewarm surface produces a grey, steamed exterior, not a crust.

Sear times

• Flat faces: 60–90 seconds per side. Set a timer and commit. The steak is already at near-target internal temperature, so the sear is about crust only, not cooking the centre further.

• Fat-cap edge and opposite thin edge: 30–45 seconds each, held upright with tongs. This renders the fat and builds flavour on surfaces that would otherwise go pale and soft.

Resist the urge to extend the sear. Longer does not mean better crust; it means higher internal temperature and a thinner window for a perfect result.

Use your backyard BBQ

A charcoal kettle or gas BBQ cranked to maximum over direct heat is the ideal searing tool for a tomahawk. It handles the bone, the size and the heat requirements without the ventilation headaches of a cast iron pan indoors. This is exactly what the Australian backyard setup was built for.

Resting, Carryover Cooking and Why You Cannot Skip This Step

Once the sear is done, step away from the heat. What happens in the next 10 minutes is just as important as everything that came before it.

Carryover cooking is the reason you pull a steak before it hits your target temperature. Even off the heat, the steak's internal temperature keeps climbing by roughly 2–4°C (3–7°F), because the scorching hot outer layers continue pushing residual heat toward the cooler centre. If you wait until the thermometer reads your target, you have already overshot it.

What Temperature to Aim For

Use these final resting temperatures as your targets after carryover:

• Rare: 52°C (125°F)

• Medium-rare: 55–57°C (131–135°F)

• Medium: 60–63°C (140–145°F)

One important note on food safety: Food Standards Australia New Zealand (FSANZ) recommends whole muscle beef be cooked to a minimum of 63°C (145°F). Rare and medium-rare fall below that threshold, so factor in your guests when choosing a doneness level. Pregnant women, young children, elderly guests and anyone immunocompromised should always be served beef cooked to the FSANZ minimum.

How to Rest a Tomahawk Properly

Transfer the steak to a warm cutting board and tent loosely with foil, leaving the ends open so steam can escape. Hold it there for 8–12 minutes. The foil traps just enough warmth without cooking the steak further.

During the rest, the muscle fibres relax and the juices redistribute back through the meat. Cut too early and those juices pool on the board instead of staying in every bite.

Resting matters even more with reverse sear. The steak has spent an extended period under gentle heat before the sear, so the muscle fibres are already under tension. The high-heat sear compounds that. A full rest is not optional here; it is what separates a juicy result from a disappointing one. For a deeper look at why resting transforms large cuts, the science behind resting explained in our beef brisket guide covers it in detail.

Use the rest time well. Plate up your sides, warm your serving plates and get your carving knife and board ready. By the time the steak is carved, everything else should already be on the table.

How to Carve and Serve a Tomahawk Steak

Once the resting time is up, it's time for the most satisfying part: breaking this thing down and getting it on the board.

Remove the bone first

Stand the bone upright with one hand and run a sharp knife along its natural curve, keeping the blade close to the bone the whole way. The meat separates cleanly in a few strokes. Don't discard the bone; lay it on the board as an anchor for your presentation.

Slice against the grain

On a tomahawk ribeye, the muscle fibres run roughly lengthways along the steak. Cutting perpendicular to them, across that direction, shortens each fibre in the slice and makes every mouthful noticeably more tender. Aim for slices about 1 to 1.5 cm thick. If you cut with the grain instead, even a perfectly cooked steak can feel chewy.

Presentation that earns its moment

Fan the slices out from the bone on a large timber or slate board. Finish with a pinch of flaky salt and a few sprigs of fresh rosemary or thyme if you have them. The contrast of the dark crust, the pink interior and that long bone makes for a genuinely dramatic centrepiece. For more ideas on how to style a meat board for guests, the serving suggestions in this lamb leg roast recipe translate well to larger cuts.

How many people will it feed?

A 1 kg tomahawk comfortably feeds 2 to 3 people as a main alongside sides. If you're cooking for a bigger group, plan accordingly rather than relying on one steak to stretch. Leftovers the next day are excellent eaten cold or quickly seared in a hot pan for 30 seconds a side.

Sides that work in an Australian backyard

Keep the sides simple so they don't compete. Charred broccolini, roasted kipfler potatoes and a crisp green salad all work well. If you want something with a bit of heat and smokiness, corn on the cob seasoned with Stoneville BBQ's Blistered Kernels is a natural match for the richness of the tomahawk and rounds out the spread nicely.

Oven, Smoker or Grill for the Low-Heat Phase: Which Should You Use?

Now that your tomahawk is rested and carved, it's worth stepping back to address a question that comes up constantly: does it matter which appliance you use for the low-heat phase?

The honest answer is that each option works. What separates them is convenience, flavour and how much attention they demand.

Oven

The kitchen oven is the most accessible starting point for most cooks. It holds a steady temperature reliably, it ignores wind and weather, and it requires almost no monitoring once dialled in. The trade-off is straightforward: no smoke, no added flavour complexity. You will also need to move the steak outside or to a cast iron pan for the sear, which adds a transition step.

Smoker

A smoker, whether offset, pellet or a lidded kettle set up for indirect cooking, delivers the most flavour. Australian hardwoods like ironbark and red gum are excellent choices here. They produce a subtle, earthy smoke that complements the tomahawk's richness without overwhelming it. Temperature control does require more active management than an oven, and results will vary more between cooks. That said, when it comes together, the result is genuinely exceptional.

Covered Charcoal or Gas BBQ

For most Australian backyards, this is the practical sweet spot. Set up a two-zone fire by placing coals or lighting burners on one side only. The tomahawk sits on the cool side with the lid on for the low-heat phase, then slides directly over the heat for the sear. No equipment changes, no transitions between appliances.

The Variable That Actually Matters

Regardless of which option you choose, maintaining a stable 110–120°C (230–250°F) throughout the low-heat phase is what drives a consistent result. A thermometer that tracks both ambient cooker temperature and internal meat temperature simultaneously is genuinely worth the investment.

One honest note: BBQ results vary. Equipment calibration, ambient weather, steak thickness and cook experience all play a role. Treat the timing chart and temperature targets in this guide as reference points, not guarantees. Your thermometer makes the final call, every single time.

Common Reverse Sear Mistakes and How to Avoid Them

Even with the right equipment and heat source sorted, a few common errors can undo an otherwise well-executed cook. Here is what goes wrong most often, and how to sidestep each one.

Pulling the steak too late in the low-heat phase. This is the most costly mistake. Overshooting your pull temperature by even 5 to 6°C means the sear will push the final result into medium or medium-well territory. Start probing earlier than feels necessary, well before you expect the steak to be ready. The thermometer, not the clock, makes that call.

Not getting the sear surface hot enough. A grill or cast iron that is merely warm produces a grey, steamed crust rather than the deep, caramelised bark you are after. Give your grill or pan a full 10 to 15 minutes at maximum heat before the steak goes on. Also avoid crowding the surface; placing anything else alongside the tomahawk during the sear traps steam and works against crust development.

Skipping the dry brine. Seasoning a steak immediately before cooking sits largely on the surface and does little for the interior. Applying your seasoning at least one hour ahead, and ideally the night before, gives salt time to draw moisture out, dissolve and reabsorb back into the meat. The result is deeper flavour and a noticeably better crust.

Cutting too soon after the sear. Resting is not a suggestion. Slice too early and the juices pool on the board instead of staying in the meat. Allow the full 8 to 12 minutes covered loosely with foil before you pick up the carving knife.

Using a tomahawk that is too thin. Reverse sear is built around thickness. A steak under 3.5 cm will cook through during the low-heat phase before you get meaningful temperature control. If the only tomahawks available are on the thin side, a standard direct-grill method will likely serve them better than trying to force the technique.

Light the Fire and Make It a Night to Remember

Avoid the mistakes covered above, and you have everything you need to cook a tomahawk that genuinely earns the applause.

The core insight is simple: thickness is the tomahawk's greatest asset when you use the reverse-sear method. Gentle, even heat at 110–120°C (230–250°F) brings the internal temperature up gradually and consistently, giving you real control over the final result. Then one ripping-hot sear at 260°C+ (500°F+) delivers the crust and the drama that makes this cut a genuine showstopper on any table.

The quick-reference summary:

• Season early and boldly, with Stoneville BBQ's Pindan Ironstone or a quality SPG, ideally overnight

• Cook low and slow until the internal temperature hits 46–49°C (115–120°F)

• Sear hard for 60–90 seconds per side on a properly preheated grill

• Rest for 8–12 minutes before touching the knife

• Carve against the grain for maximum tenderness

No technique produces perfect results every single time. Equipment varies, steaks vary, and weather has its own agenda. What does improve is your ability to read the cook, trust your thermometer and make adjustments on the fly. The first tomahawk you reverse sear will teach you more than this guide can. The second will be noticeably better. That is how BBQ works.
