In summary
· Reverse sear is best for thicker steaks, giving you even doneness inside and a hard, sizzling crust at the end.
· Sear-first is faster and works well for thinner steaks, but it needs more attention to avoid overcooking.
· A meat thermometer is the secret to repeatable results, especially when cooking over charcoal.
Why does steakhouse crust feel so hard to get at home?
You know the steak I mean. Deep brown crust. Juicy centre. A little char around the edges. The kind of steak that makes everyone at the table go quiet for the first few bites.
The good news is you can get that result on a charcoal BBQ. The trick is learning when to use high heat, when to use gentle heat, and when to stop guessing.
What is the reverse sear method?
Reverse sear means you cook the steak gently first, then finish it with a ripping-hot sear.
Instead of starting over direct heat, you begin with the steak on the cooler side of the BBQ. The lid stays closed, and the steak slowly comes up to temperature. Once it is close to your target doneness, you move it over hot charcoal to build the crust.
Think of it as roasting first, then searing.
Reverse sear is especially good for thick steaks because it gives the inside time to cook evenly before the outside gets blasted with heat.
What is the sear-first method?
Sear-first is the classic steak method. You start by placing the steak directly over hot charcoal to form the crust, then move it to the cooler side of the BBQ to finish cooking through.
It is fast, exciting, and very satisfying. You get that instant sizzle, the smoke smells incredible, and everyone suddenly appears near the BBQ asking when dinner is ready.
The challenge is timing. Because the steak is hit with high heat first, thinner cuts can overcook quickly. Sear-first works beautifully, but you need to pay attention.
Which steak thickness suits each method?
Thickness is the easiest way to choose your method.
For steaks under 2.5cm thick, use sear-first. These cook quickly, so there is not much benefit in reverse searing.
For steaks around 2.5cm to 3.5cm thick, either method can work. Reverse sear gives you more control, while sear-first gives you speed.
For steaks 4cm and thicker, reverse sear is usually the better choice. Ribeye, tomahawk, thick sirloin, scotch fillet, porterhouse, T-bone, and thick-cut rump all respond well to reverse searing.
A good rule: the thicker the steak, the more useful reverse sear becomes.
What BBQ setup do you need?
For both methods, set up a two-zone charcoal fire.
Place your lit charcoal on one side of the BBQ and leave the other side empty. The charcoal side is your direct heat zone. The empty side is your indirect heat zone.
This setup gives you control. You can sear over the coals, then move the steak away from the heat if things are moving too quickly.
For reverse sear, start on the indirect side and finish over the coals.
For sear-first, start over the coals and finish on the indirect side.
How should you control the vents?
Charcoal temperature is all about airflow. More air means more heat. Less air means a slower fire.
For the gentle cooking stage, keep the bottom vent partially open and the top vent about half to three-quarters open. You want steady heat, not a raging fire.
For the searing stage, open the vents fully. Give the charcoal oxygen and let the grill get hot. If you are using a kettle BBQ, leave the lid off briefly while searing if you want maximum surface heat, or close it between flips to keep the fire strong.
For reverse sear, I like to let the steak cook gently with the lid closed, then remove the lid for the final sear. That last minute over hot charcoal is where the magic happens.
What internal temperatures should you aim for?
Use these as practical steak doneness targets. Pull the steak slightly before the final temperature because it will rise a little as it rests.

Australian food safety authorities such as the NSW Food Authority and Food Safety Information Council lists 63°C / 145°F with a 3-5 minute rest as the minimum safe internal temperature for beef, pork, veal, and lamb steaks, chops, and roasts. Many people choose lower steak temperatures for preference, but anyone cooking for children, pregnant people, older adults, or immune-compromised guests should be more cautious.
How do you use a thermometer properly?
Insert the probe into the thickest part of the steak, entering from the side if possible. This helps you measure the centre, not just the top surface.
Avoid touching bone or large fat pockets, because they can give misleading readings. Check more than one spot on thick steaks, especially T-bones or tomahawks, where different muscles can cook at slightly different speeds.
Do not wait until the steak “looks done.” Colour can trick you. A thermometer turns steak from guesswork into a repeatable process.
Once you know your preferred pull temperature, write it down mentally. Next time, you can hit it again.
How do you reverse sear steak on charcoal?
Start by lighting your charcoal in a chimney starter. Once the coals are glowing and lightly ashed over, pour them onto one side of the BBQ.
Pat the steak dry with paper towel. Season generously with salt. You can add pepper before cooking, though some BBQ cooks prefer adding pepper after searing to avoid scorching.
Place the steak on the indirect side of the BBQ, away from the coals. Close the lid. Keep the top vent positioned over the steak so heat and smoke move across the meat before leaving the BBQ.
Cook gently until the steak is about 8–10°C below your final target temperature. For medium-rare, that usually means pulling it from the indirect side at around 45–48°C.
Now open the vents fully and get ready to sear. Move the steak directly over the charcoal. Sear for 45–90 seconds per side, flipping often until the crust is dark, sizzling, and even.
Rest for 5–10 minutes before slicing.
How do you sear-first steak on charcoal?
Light your charcoal and set up the BBQ with a hot direct zone and a cooler indirect zone.
Pat the steak dry and season well. Moisture is the enemy of crust, so do not skip the drying step.
Place the steak directly over the charcoal. Sear for 1–2 minutes per side, depending on thickness and heat. Flip often if the crust is developing too fast or if fat is causing flare-ups.
Once the steak has a good crust, move it to the indirect side. Close the lid and let it finish gently until it reaches your pull temperature.
This method is great when you want dinner moving quickly. It also works well for thinner steaks where reverse searing would be unnecessary.
Which method gives the better crust?
Both can give you steakhouse crust.
Reverse sear often gives you the most even doneness and a cleaner final sear because the surface has dried slightly during the gentle cooking stage. That drier surface browns beautifully.
Sear-first gives you a fast, bold crust early, but you need to manage the finish carefully. If the steak is thin, you may not need much indirect time at all.
For thick steaks, reverse sear wins for control.
For weeknight steaks, sear-first wins for speed.
What simple timing table should you follow?
Timing depends on steak thickness, charcoal heat, lid position, and starting temperature, so treat this as a guide rather than a rulebook.

The thermometer matters more than the clock. The table helps you plan, but the internal temperature tells you when to move.
How do you get a better crust?
Start with a dry steak. Pat it down well before seasoning.
Use enough charcoal. A weak fire will cook the steak but will not give you that steakhouse crust.
Do not overcrowd the grill. Steaks need heat around them. If the BBQ is packed too tightly, the surface can steam instead of sear.
Flip more than once if needed. The old “only flip once” rule is not essential. Frequent flipping can help build an even crust while reducing the chance of burning.
Rest the steak before slicing. A short rest helps the juices settle and gives you a better eating experience.
Which method should you choose?
Choose reverse sear for thick steaks, special occasion cuts, tomahawks, ribeye, scotch fillet, porterhouse, and any steak where you want edge-to-edge doneness.
Choose sear-first for thinner steaks, quick dinners, open-grill cooking, and times when you want a fast crust without a long setup.
For beginners, reverse sear is often more forgiving. It slows the process down, gives you time to check temperature, and finishes with that big charcoal sear everyone loves.
Once you understand both methods, you will use them for different moods. Reverse sear for the weekend hero steak. Sear-first for a Friday night steak and salad.
Either way, hot charcoal, good seasoning, vent control, and a thermometer will get you far closer to steakhouse results than guesswork ever will.
FAQs
Is reverse sear better than sear-first for steak?
Reverse sear is usually better for thick steaks because it gives you more control over the internal temperature. The steak cooks gently first, then finishes over high heat for the crust. Sear-first is still a great option for thinner steaks or quicker cooks, but it can be easier to overshoot the doneness if the steak is thick.
How thick should a steak be for reverse searing?
Reverse searing works best with steaks around 3.5cm thick or more. Thick ribeye, scotch fillet, porterhouse, T-bone, sirloin, and tomahawk steaks are all good choices. Thinner steaks can cook too quickly during the gentle stage, so they often suit the sear-first method better.
What temperature should I pull steak at for reverse sear?
For medium-rare, remove the steak from the indirect side at around 45–48°C, then sear it hard over the charcoal until it reaches roughly 52–54°C before resting. The temperature will continue to rise slightly while resting. For other doneness levels, aim to move from indirect heat to searing when the steak is about 8–10°C below your final target.
Do I need a thermometer to cook steak on charcoal?
You can cook without one, but a thermometer makes the results much more reliable. Charcoal heat changes as the cook goes on, and steak thickness can vary a lot. A thermometer helps you know when to move the steak, when to sear, and when to rest it, instead of relying only on colour or feel.
Should I cook steak with the BBQ lid open or closed?
For the indirect stage, keep the lid closed so the BBQ behaves like an oven and cooks the steak evenly. For the searing stage, you can cook with the lid open to focus strong heat on the surface, or close it briefly between flips to keep the fire roaring. The key is to avoid leaving the lid open too long during the gentle cooking stage, because the temperature will drop.
How do I get a better crust on charcoal steak?
Start with a dry steak, season it well, and make sure your charcoal is properly hot before searing. Moisture on the surface slows browning, so pat the steak dry before it goes on the grill. Use a two-zone setup so you can control the cook, then finish directly over the hottest coals for that deep, steakhouse-style crust.
Glossary of terms
Reverse sear: A steak cooking method where the steak is cooked gently first using indirect heat, then finished over high heat to build a crust.
Sear-first: A method where the steak is seared over direct heat first, then moved to indirect heat to finish cooking.
Direct heat: Cooking food directly above the charcoal. This is used for searing, charring, and fast grilling.
Indirect heat: Cooking food away from the charcoal, usually with the lid closed. This is used for slower, more even cooking.
Two-zone fire: A charcoal setup with hot coals on one side and a cooler area on the other, giving you both direct and indirect heat.
Pull temperature: The internal temperature at which you take the steak off the BBQ before resting.
Final temperature: The internal temperature the steak reaches after resting.
Carryover cooking: The rise in internal temperature that happens after the steak comes off the BBQ.
Resting: Letting steak sit for a few minutes after cooking so the juices settle before slicing.
Crust: The browned, flavour-packed outer layer of the steak created by high heat.
Vent control: Adjusting the BBQ vents to manage airflow and temperature. More airflow usually means hotter charcoal.
Lid-down cooking: Cooking with the BBQ lid closed so heat circulates around the steak more evenly.
Meat thermometer: A tool used to check the internal temperature of steak so you can cook to your preferred doneness more consistently.
