How long do I cook burgers on a gas grill?
150 g patties, three-burner gas, direct, United Kingdom
Answered
More than one independent publisher covers this, and nothing in the evidence contradicts anything else.
The question, as BBQHQ read it
- Food
- Beef burger
- Heat
- direct
- Where
- GB
- Weight
- 150 g
- Thickness
- 20 mm
- Starting state
- fridge cold
- Quantity
- 6 pieces at once
The cooking window
Estimated cooking window
8 min–15 min
Moderate confidence
Why this is a range, not a number
- Thickness varies between pieces
- Cookers hold temperature imperfectly
- Individual animals and pieces differ
Cook to the endpoint, not to the clock. The window tells you when to start checking.
Why this is not stronger
- At least one source does not state the cooker temperature.
- No source states whether the food went on fridge-cold or rested.
- No source states the weight of the food.
How the window was built
- Base, from matched guidance: 8 min–12 min
- Straight from the fridge: +0 min–1 min
Food going on cold has further to travel. The effect scales with the length of the cook rather than being a fixed number of minutes.
- 6 pieces on at once: +0 min–2 min
A loaded grate absorbs more heat, drops the chamber temperature further each time the lid opens, and recovers more slowly.
- Final window: 8 min–15 min
When is it done? Separate questions, separate answers
“Done” means several things and they do not coincide. The safety endpoint is set by the jurisdiction you are cooking in and is not a matter of taste. Culinary doneness is what you want. The texture endpoint is how you actually tell.
Food-safety endpoint
BBQHQ holds no food-safety rule for this food in GB. We are not showing you another jurisdiction’s figure in its place — check your national food-safety authority.
Culinary doneness — a preference, not a safety figure
cooked through — 71–75 °C (160–167 °F)
Measure at: The centre of the patty, probing from the side.
Unlike a steak, a burger has no sterile interior: mincing distributes surface bacteria throughout. A rare burger is a different proposition from a rare steak and requires controls that domestic cooking does not provide.
Where this comes from
In the United States, ground beef has a safe minimum internal temperature of 160 °F (71 °C) — higher than the whole-cut figure, because of mincing.
Well established
United States Department of Agriculture, Food Safety and Inspection Service — States this directly
USDA FSIS gives 160 °F (71 °C) as the safe minimum internal temperature for ground beef.
- Form:
- Ground/minced meat. Higher than the whole-cut figure precisely because of mincing.
- No rest time is specified for ground meats.

Hazards, by kind
These are not about when the food is done. They are about whether the activity is safe where you are doing it, and each kind sits under its own heading because they are answered in different ways.
Equipment safety
Failure, stability, assembly and maintenance of the cooker itself.
Weber charcoal barbecues: outdoor use only Critical
Weber instructs that its charcoal barbecues must not be used indoors, in a garage, building or breezeway, or any other enclosed area, and not under any overhead combustible construction. Coals and ashes must be fully extinguished before the barbecue is stored.
Wire brush bristles can end up in food Significant
A bristle shed by a wire grill-cleaning brush can be left on the bars, picked up by the next thing cooked on them and swallowed. Documented cases have required surgery to remove it.
Electric does not mean indoor-safe Significant
An electrically powered outdoor cooker is not automatically safe to use indoors. Producing no carbon monoxide removes one hazard; it does not remove fire risk, smoke, or the manufacturer's own restriction on where the appliance may be used.
Electric smokers: earthed supply, RCD protection, outdoor-rated cord Significant
Masterbuilt instructs that its electric smoker runs only from a properly earthed outlet, is supplied through a residual current device rated at no more than 30 mA, and uses only a grounding-type three-wire outdoor extension cord kept dry and off the ground. The supply cord is to be examined regularly and the appliance not used if it is damaged.
Carbon monoxide
Carbon monoxide from burning fuel. Invisible, odourless, and the reason no combustion cooker belongs in an enclosed space.
Never take a barbecue into an enclosed space Critical
Never take a barbecue into a tent, awning, caravan, motorhome, garage, shed or any other enclosed space — including to keep warm, and including when it is no longer flaming.
A cooling barbecue is still producing carbon monoxide Critical
A barbecue continues to give off carbon monoxide as it cools. Never bring one inside to finish cooling, and never store one indoors until it is completely cold.
Electric smokers still produce carbon monoxide — from the wood, not the element Critical
An electric smoker's heat comes from a mains element that burns nothing, and the appliance still emits carbon monoxide, because the wood chips it makes smoke with are burning inside the cabinet. Masterbuilt warns that burning wood chips gives off carbon monoxide, which has no odour and can cause death, and that chips must never be burned inside homes, vehicles, tents, garages or any enclosed area.
Offset smokers: never under an overhead structure of any kind Critical
Oklahoma Joe's instructs that its smoker be used only in a well-ventilated space and never in an enclosed one — naming a carport, garage, porch, covered patio or any overhead structure — and warns that burning charcoal indoors can kill because it gives off odourless carbon monoxide.
Never bring a barbecue indoors to cool Critical
Never bring a barbecue indoors, into a tent or into a garage while it is cooling. A finished barbecue is still producing carbon monoxide and can still start a fire.
Fire safety
Preventing and controlling unintended fire around a cooker.
UK: do not use a barbecue on a balcony Critical
Do not use a barbecue on a balcony. Flames, sparks and hot embers can start a fire that spreads quickly to other parts of the building.
UK: putting out and disposing of coals and ash Critical
Let the barbecue cool and make sure it is properly out before disposing of coals or ash, and never put them in a bin while they are still warm. Smouldering ashes give off carbon monoxide and stay a fire risk for hours after cooking has finished.
UK: where to stand a barbecue, and never leave it Significant
Stand a barbecue on level ground and not on decking, well away from anything that could catch fire — sheds, fences, trees. Never leave it unattended while it is lit.
UK: lighting a barbecue, and local bans on disposables Significant
Never light a barbecue in an enclosed space, and do not use accelerants to get it going. Check local rules before taking a disposable barbecue to a park or open space — many London parks have banned them because of grass-fire risk.
Gas safety
LPG and natural gas: connections, leaks, cylinders and storage.
UK: what not to do with a gas regulator or cylinder fitting Critical
Never force a regulator onto a cylinder valve that it does not fit easily, never work its mechanism with excessive force, and never tamper with or adjust a regulator that is not user-adjustable. Tighten screwed connections with the correct sized spanner and do not over-tighten — most cylinder connections use a left-hand thread and tighten the opposite way to a normal screw. Gas components on a barbecue are replaced, not repaired.
UK: when an LPG regulator has to be replaced Significant
Replace an LPG regulator on the service life its manufacturer states, or after ten years if none is stated, and straight away at any sign of wear, leakage or damage whatever its age. A regulator marked BS 3016 is already past that life. Keep its vent clear and pointing where rain cannot get in, and never fit a second-hand one.
Fuel handling
Lighting, handling and disposing of charcoal, wood and firelighters.
UK: never pour petrol, paraffin or meths on a barbecue Critical
Never pour petrol, paraffin or methylated spirits onto a barbecue or a fire, lit or unlit. Use firelighters, or a chimney starter.
Spent coals can reignite for up to 24 hours Significant
After a charcoal fire appears extinguished, unconsumed embers can retain heat for up to 24 hours and can burst into flame unexpectedly when fresh air reaches them. Embers outside the firebox can ignite combustible surfaces such as a wooden deck.
Electrical safety
Mains power outdoors, cables, water and residual current protection.
UK: use a residual current device for anything that plugs in Significant
Use a residual current device with any mains-powered cooker or equipment used outdoors. If your fusebox does not have one built in, use a plug-in RCD at the socket.
UK: dew counts as wet Significant
Do not run a mains-powered cooker outdoors while the ground or the equipment is wet. Electrical Safety First sets the threshold at dew on the ground, not at rain.
UK: the lead is part of the appliance Significant
Use only extension leads, reels and connectors rated for outdoor use — weather-resistant, with moulded connections. Check them for damage before plugging in, uncoil a reel completely, and use one with a thermal cut-out.
UK: unplug before you fiddle with it Moderate
Switch off and unplug a mains-powered cooker before cleaning, adjusting or checking it.
Wildfire and environment
Fire spreading beyond the cook: dry ground, decking, wind and wildfire risk.
UK: the ground stays hot after the fire is out Significant
The ground under a fire or a disposable barbecue stays hot for some time after the fire has gone out. Let coals and embers cool completely before throwing them away.
The working
How the sources were combined
- 1.Reconciling 2 observation(s) that bear on the duration. 4 further observation(s) — endpoints, doneness ladders, pull temperatures — are evidence about this cook and are NOT counted as opinions about its length.
- 2.All observations describe compatible conditions; they form one group.
- 3.6 temperature pair(s) held apart rather than combined, because they answer different questions.
- 4.Unstated by at least one source: cooker temperature, weight, starting temperature. Treated as uncomparable, not as agreement.
- 5.Combined as the union of reported durations: 8–12 minutes. Union, not mean — the window contains every source's figure.
- 6.Confidence: moderate — 2 independent publisher(s), with 3 condition(s) unstated.
- 7.Evidence about this cook that is not evidence about its length: United States Department of Agriculture, Food Safety and Inspection Service, United States Food and Drug Administration, New Zealand Food Safety / Ministry for Primary Industries, Food Standards Australia New Zealand. Retained as provenance, excluded from corroboration.
Held apart on purpose
Figures that look like they should be compared and must not be. Different question, different jurisdiction, or different doneness — not a dispute.
- Different regulatory regimes (guidance for people cooking against requirement on food businesses). 71 °C and 68 °C answer different questions asked of different people, and neither overrides the other.
- Different jurisdictions (usda-fsis-us and nzfs-mpi-nz) for a jurisdictional endpoint. Both are correct where they apply, and neither overrides the other.
- Different jurisdictions (usda-fsis-us and fsanz-au-nz) for a jurisdictional endpoint. Both are correct where they apply, and neither overrides the other.
- Different jurisdictions (nzfs-mpi-nz and fsanz-au-nz) for a jurisdictional endpoint. Both are correct where they apply, and neither overrides the other.
How this answer was classified
- 1.57 published profile(s) considered; 1 cover this question.
- 2.Answered: confidence moderate, 2 publishers corroborating the cooking time, no unresolved disagreement.
Beef burger, direct heat
Two independent publishers with overlapping windows at compatible thicknesses: AHDB gives 4–6 minutes a side for a 1–2 cm patty and Weber 8–10 minutes total for a ¾-inch one. Combined as a union of 8–12 minutes. BBQHQ could give no duration here at all for a long time. The endpoints, meanwhile, remain separate jurisdictional figures — 71 °C in the US, 75 °C in New Zealand and across Australia and New Zealand under FSANZ, and the UK's time-and-temperature combinations — and they are deliberately not reconciled with each other, because they are different authorities' decisions rather than competing estimates of one fact. A fifth figure was added that is not a fifth jurisdiction: the FDA Food Code's 68 °C held for 17 seconds is the same country as the USDA's 71 °C and a different REGIME, addressed to food businesses rather than to the reader. It is held apart on that basis, it does not appear in the endpoints a reader is shown, and the US guidance here is unchanged.
The safety rules behind this profile
A beef burger cannot be treated like a steak: mincing moves surface bacteria into the interior, so serving one rare or pink requires controls that a whole cut does not.
Well established
Food Standards Agency — States this directly
The FSA publishes separate guidance for less than thoroughly cooked beef burgers, covering controls that reduce the risks of serving them rare or pink — controls that whole cuts of beef do not require.
- Written for food businesses and local authorities rather than for domestic cooks.
- Why it happens:
- Mincing distributes surface bacteria through the interior, so the interior of a burger cannot be treated like the interior of a steak.

Tenderised meat is grouped with minced meat rather than with whole cuts, and must be cooked through when barbecued.
Well supported
New Zealand Food Safety / Ministry for Primary Industries — States this directly
New Zealand Food Safety advises that chicken, tenderised meat and minced meat products need to be barbecued until they are cooked through, over 75 °C all the way through.
- Form:
- Groups tenderised meat with mince rather than with whole cuts — direct support for treating mechanical tenderisation as an interior-contamination form.
- Stated specifically in the context of barbecuing.

Across Australia and New Zealand, FSANZ advises cooking chicken, sausages and hamburgers thoroughly to an internal temperature of 75 °C, while stating that steaks may be cooked to preference.
Well established
Food Standards Australia New Zealand — States this directly
“Cook chicken, sausages and hamburgers thoroughly, to an internal temperature of 75oC - check the temperature with a food thermometer.”
- Where it applies:
- Australia and New Zealand together. FSANZ's remit is bi-national, which is why a New Zealand reader is covered by this AND by MPI.
- Form:
- Names chicken, sausages and hamburgers — poultry plus the two commonest minced forms.
- Method:
- Stated in the context of sausage sizzles and barbecues specifically.
