How long does a pork shoulder take on a pellet grill?

3 kg bone-in shoulder, pellet grill, low and slow, United States

Not established

This is a fair question and BBQHQ does not have the evidence to answer it. The gap is recorded by name rather than filled with a guess.

The question, as BBQHQ read it

Food: Pork shoulder
Cooker: Pellet grill
Heat: low and slow
Where: US
Weight: 3.0 kg
Starting state: fridge cold

Why there is no window here

The gap is registered and named below. It is open work, not an oversight.
The safety endpoint is inherited from the whole-cut observation and is passed several hours before the joint is ready — which is the entire point of this record. The National Pork Board's texture endpoint of 185–190 °F with the bone slipping free is a genuine improvement on the unsourced description it replaced. Its DURATION is still not published, because the Pork Board expresses it as a rate per pound rather than a window, and turning that into hours means choosing a weight — arithmetic that would be BBQHQ's and would arrive on the page looking like the source's.

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

USDA Food Safety and Inspection Service
In the United States, whole cuts of beef, pork, lamb and veal — steaks, chops and roasts — should reach 145 °F (63 °C), followed by a rest of at least three minutes before carving or eating.
- 63 °C (145 °F) — measured at the centre of the thickest part, away from bone and fat.
The rule and its source
In the United States, whole cuts of beef, pork, lamb and veal have a safe minimum internal temperature of 145 °F (63 °C), followed by a rest of at least three minutes.
Well established
- United States Department of Agriculture, Food Safety and Inspection Service — States this directly
  “Cook raw beef, pork, lamb and veal steaks, chops, and roasts to a minimum internal temperature of 145 °F ... allow meat to rest for at least three minutes”
  Form:
  Whole cuts only. Ground meats are covered by a separate, higher figure.
  The three-minute rest is part of the safety requirement, not only a quality step.
  How it was measured:
  As measured with a food thermometer before removing from the heat source.

Texture endpoint — how you actually know

Probe tender — the joint pulls apart under light pressure and the bone slips free

A probe or skewer slides into the thickest part with almost no resistance, and the blade bone can be pulled clean out by hand. The National Pork Board gives the same signal and puts it at around 85–88 °C. This happens long after the meat is safe to eat, and no thermometer reading substitutes for the feel.

Indicative only: 85–96 °C (185–205 °F). This is not a target to cook to — the feel decides.

Where this comes from

Smoked pork shoulder is taken to roughly 85–88 °C, far above any safety endpoint, and the National Pork Board's stated signal is that the bone slips easily from the meat.

Limited evidence — treat with caution

National Pork Board — States this directly
The National Pork Board gives a target internal temperature of 185 to 190 °F for smoked pork shoulder, at which point it states the bone will slip easily from the meat, and expresses the time as a rate of about one hour and fifteen minutes per pound.
Endpoint:
185–190 °F, about 85–88 °C. Far above the 145 °F safety figure on the same publisher's grilling chart.
Form:
The duration is a RATE per pound, not a total, so it cannot be recorded as a duration without choosing a weight.
The bone slipping free is a physical signal, not a temperature.

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.
Ninja Woodfire: outdoor household use only, three feet of clearance Critical
SharkNinja instructs that the Ninja Woodfire Pro XL is for outdoor household use only, with a minimum of 3 feet from its rear, sides and top to walls, rails or other combustible construction, and at least 1 foot from the pellet box while smoking. Only food-grade wood pellets may go in the smoke box — never charcoal, hardwood or liquid fuel.
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.

Fuel handling

Lighting, handling and disposing of charcoal, wood and firelighters.

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.

The working

How the sources were combined

1.Reconciling 0 observation(s) that bear on the duration. 2 further observation(s) — endpoints, doneness ladders, pull temperatures — are evidence about this cook and are NOT counted as opinions about its length.
2.Observations fall into 0 incompatible groups. They will NOT be combined.
3.1 temperature pair(s) held apart rather than combined, because they answer different questions.
4.No combined window produced. Incompatible groups are reported separately.
5.Confidence: low — the observations do not describe one cook (0 independent publisher(s)).
6.Evidence about this cook that is not evidence about its length: National Pork Board, United States Department of Agriculture, Food Safety and Inspection Service. 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 outcomes: texture endpoint against food-safety endpoint. These answer different questions and are not combined.

How this answer was classified

1.57 published profile(s) considered; 1 cover this question.
2.Profiles matched, and every one of them records that the duration is not established.

The safety rules behind this profile

In the United States, whole cuts of beef, pork, lamb and veal have a safe minimum internal temperature of 145 °F (63 °C), followed by a rest of at least three minutes.

The same Food Standards Agency guidance names pork and chicken, with minced products, as foods that should not be served pink or rare — placing whole cuts of pork on the opposite side of the sentence from whole cuts of beef and lamb.
