Reheat leftover BBQ chicken in a covered 180°C oven (fan 160°C) for about 15–20 minutes, or on the barbecue over indirect heat for 10–15 minutes, until the thickest part reads 75°C. Microwave and air fryer times are below too, with how to keep it from drying out.

Best path for leftover BBQ chicken: covered oven at 180°C (fan 160°C) for about 15–20 minutes, or the barbecue over indirect heat for 10–15 minutes — always to 75°C in the thickest part.
Need the short “how long” answer? Pieces are usually 15–20 minutes in a covered 180°C oven, or 10–15 minutes on the barbecue over indirect heat — always to 75°C inside.
Reheat times at a glance (°C)
Times are a starting point from fridge-cold leftovers. Stop when the thickest part reads 75°C — the clock is secondary.

Safe temperature for reheated chicken (Australia)
Home leftover target
Aim for 75°C in the centre of the thickest piece. That matches Food Safety Information Council guidance for reheated leftovers and poultry.
Food Standards Australia New Zealand (FSANZ) also talks about reheating for food businesses that will hot-hold food — those rules use a rapid reheat to 60°C or hotter. That is a different job to warming Saturday’s chook for Sunday dinner. In this guide we stick to the 75°C leftover target so you have a clear home number on the probe. See FSANZ cooling & reheating and Australian Chicken Meat Federation food safety.
Other calm rules that matter more than gadgets:
Fridge leftovers within two hours of coming off the grill.
Reheat once. What you do not eat the second time goes in the bin.
Do not thaw on the bench — fridge overnight, or microwave then cook/reheat straight through to 75°C.
Why leftover BBQ chicken dries out
Avoid reheating chicken breast too aggressively — it dries out fast. Dark meat (thighs, drumsticks) forgives a little more heat. Always reheat to 75°C internal, then pull promptly. Moisture (stock, a loose foil wrap, or sauce at the end) beats blasting on high heat.
Best Method
Oven or BBQ — maintains crispy skin
Oven
180°C (350°F) for 15–20 min
Microwave
2–3 min on medium power
BBQ
10–15 min over indirect heat
Oven reheat (covered)
Preheat to 180°C (fan-forced 160°C). Put pieces in a dish with a spoon of stock or water, cover with foil, and warm until the probe reads 75°C. Uncover for the last couple of minutes if you want the skin to tighten. Sliced breast wants the shorter end of the range — pull it the moment it hits temperature.
How to reheat BBQ chicken on the grill
If the barbecue is already lit, indirect heat is the closest you will get to the first serve.
Two zones: burners or coals on one side only. On a hooded gas barbecue, one burner on low–medium, the rest off. On charcoal, bank the coals to one side.
Lid temperature: roughly 150–180°C under the hood. You are warming, not recooking.
Placement: chicken on the cool side, skin up if it still has skin. Lid down.
Time: about 10–15 minutes for pieces; longer for a half. Bone-in legs often need the top of that range.
Moisture (optional): a loose foil packet with a spoon of stock keeps breast from drying; open for the last few minutes if you want the skin to tighten.
Finish: if it was sauced, brush lightly and give 30–60 seconds over the hot side to set the glaze — watch it.
Probe:75°C in the thickest part, away from bone. Rest a minute on the board.
Gas vs charcoal does not change the target temperature. Charcoal can spike hotter when you lift the lid — keep the chicken on the cool side and trust the probe. For first-cook zone setup see direct vs indirect chicken and charcoal vs gas chicken.
Air fryer (if that is what is free)
An air fryer works for pieces, not a whole bird.
Preheat to about 160°C.
Light mist of oil if the skin looks dry; do not drown it.
Single layer; shake or turn once.
Start checking at 6 minutes for small pieces, 8–10 for bone-in legs.
Stop at 75°C. Air fryers finish fast — another two minutes past the mark is how leftovers turn stringy.
If you care about skin, the air fryer often beats the microwave. It will not beat a careful oven or the barbecue for a half chicken.
Best way to reheat BBQ chicken legs and thighs
Best way to reheat BBQ chicken legs: covered oven at 180°C for about 20 minutes, or BBQ indirect with the lid down for roughly 15 minutes, until the probe reads 75°C near the bone without touching it. Dark meat forgives a little more heat than breast, but bone-in pieces still need those extra minutes in the middle.
Thighs follow the same pattern. If the legs were sauced, warm them through first, then glaze at the end so sugar in the sauce does not burn while the centre is still cold.
Use 50–60% power in short bursts, turning between each, until the centre is steaming and the probe reads 75°C. Cover loosely so steam stays in. Skin will soften — that is the trade-off for speed.
Covered oven at 180°C for about 15–20 minutes, or BBQ over indirect heat for 10–15 minutes, until the thickest part reads 75°C. Add a splash of stock if the meat looks dry.
Can you reheat BBQ chicken in the microwave?
Yes — 2–3 minutes total on medium power in short bursts. Oven or BBQ keeps skin better; always finish at 75°C in the centre.
How long to reheat chicken on the BBQ?
Over indirect heat with the lid down at about 150–180°C, most pieces take 10–15 minutes. Bone-in legs may need closer to 15–18. Confirm 75°C in the thickest part.
What temperature should leftover BBQ chicken reach?
75°C in the centre for home leftovers (Food Safety Information Council). That is the number we use on this page.
Can I reheat BBQ chicken in an air fryer?
Yes, for pieces — about 160°C, check from six minutes, stop at 75°C. Not ideal for a whole bird.
Every time on this site comes from one place: a cook profile for each cut, holding a pit temperature, a rate, a rest time and a doneness target. You pick your cut, your smoker setting and your weight, and we do the arithmetic — rate times weight for the big cuts, a fixed window for ribs and snags, thickness for steaks. That's it. There's no secret formula, and there's nothing clever going on behind the curtain.
The honest bit is what the arithmetic can't do. Your fire isn't our fire. A brisket that stalls at two in the afternoon doesn't care what a calculator said at breakfast. Wind, lid-lifting, a fatter flat, a colder bird straight from the fridge — all of it moves the number, and none of it is something we can see from here.
So treat what we give you as a guidance window, not a guarantee. It's the answer to "roughly when should I light this thing", not "your brisket will be ready at 4:47". Cook to feel and to temperature, never to the clock — the probe slides like butter, the ribs crack when you bend them, the bone pulls clean. That's what tells you it's done. We're just here to help you work out when to get up.
What we assume
You're cooking one cut at a time, unless you've added more to the plan.
Your smoker holds the temperature you picked, give or take the usual.
Your meat starts near fridge temperature, not sitting out on the bench.
Weights are raw, before trimming.
Rest time sits on top of the cook time, not inside it.
Change any of those and the number moves. Change a few and it moves a lot.
Where these numbers come from
Every safe internal temperature on this site comes from an Australian food-safety authority, and we link to the exact page. Not a summary of it, not our reading of it — the page, so you can check us.
Cooking times are a different thing, and we'd rather be clear about the difference. Where we could find a named reference, we've used it and linked it. Where we couldn't, we say so on that cut instead of filling the gap with a guess.
Of the 20 cuts behind the calculator, all 20 carry a safe internal temperature from an Australian food-safety authority, 15 carry a cooking window from a named reference and 11 carry a cooking rate. The remaining 5 say so on the cut rather than borrowing a number from somewhere else.
Whole Chicken, Chicken Wings, Chicken Thighs and Turkey Breast — 4 of the 20 — carry a sourced safe temperature but no cooking-time reference we could find at all. Their times are still our original figures, and we would rather tell you that than let a list of citations imply otherwise.
This matters more than it sounds. Australia and the United States disagree on several meats. A sausage is 75 °C here and 71 °C there. A pork chop is 70 °C here and 63 °C there — and more than that, Australia treats a whole cut of pork the way it treats a steak, while the United States mandates a minimum the way it does for chicken. We publish the Australian figure, we say it's the Australian figure, and we record the American one alongside rather than splitting the difference. Nobody is served by an average of two countries' food-safety advice.
Still use a thermometer
None of us can tell whether something is cooked by looking at it. Cook to the temperature, not to the clock — and if our time and your thermometer disagree, your thermometer is right.
The times on this page came from the site's original cooking data. They have not all been reconciled against the sourced cook profiles above yet, and where the two disagree the sourced profile is the one with a citation behind it. That work is under way.
