Pork Shoulder
Also called pork butt, Boston butt
Slow cooking turns pork shoulder into tender, tasty meat by breaking down fibers.
Pork shoulder, also sold as pork butt or Boston butt, is the upper front leg of the pig. It is marbled with fat and threaded with connective tissue, giving it a rich, warm, earthy flavour that turns gently smoky over charcoal or a long roast.
Cooks love pork shoulder because it is cheap, generous and almost impossible to ruin with patience. Slow-cooked, it becomes pulled pork, carnitas, char siu, ragù and jerk pork, and one roast feeds a crowd with leftovers to spare.
Flavor profile
Aroma: savory, fatty, rich
Good to know
Origin: Domesticated globally, popular in European and Asian cuisines
Forms: raw, roasted, pulled
Season: Available year-round; a summer barbecue favourite and a winter roast staple.
Nutrition: A good source of protein; it is a fatty cut, so it pairs well with crunchy slaws and pickles.
Storage: Refrigerate raw pork shoulder well wrapped and cook it within 3–5 days. It freezes well for 4–6 months; thaw large roasts in the fridge, which can take 2 days. Cooked pulled pork keeps 3–4 days chilled and freezes for up to 3 months, ideally with some of its juices so it stays moist when reheated. Discard it if the surface turns slimy or it smells sour.
How to use pork shoulder
Pulled Pork Perfection
Slow roast until collagen transforms to gelatin, making the meat fall apart.
Classic Carnitas
Rendered fat adds richness; crisp it up at the end for contrast.
The science of pork shoulder
- Shoulder is packed with collagen. Held between about 70°C and 95°C (158°F and 203°F) for hours, it slowly turns into gelatin, which coats the meat fibres and makes pulled pork moist and sticky.
- The famous barbecue stall, when the internal temperature stops rising for an hour or more, happens because moisture evaporating from the surface cools the meat. Wrapping it in foil or butcher paper slows evaporation and pushes it through.
- A dry rub with salt and sugar builds bark. Salt draws out juices that dissolve the rub, then the sugars caramelise and the proteins brown through the Maillard reaction into a dark, flavourful crust.
- Fat coats the tongue and dulls flavour, so sharp partners like citrus, vinegar slaw, pickles and mustard taste brighter next to pork shoulder and keep each bite from feeling heavy.
- Fennel seed, sage and star anise carry fat-soluble aroma compounds such as anethole, which dissolve into the rendered pork fat and spread through the whole dish.
How to choose pork shoulder
Pick a shoulder with plenty of creamy white fat marbling through pink meat and a good fat cap on one side. Bone-in roasts cook a little more evenly and the bone adds flavour, while boneless ones are easier to cube for stews. Allow about 250–350 g (½–¾ lb) raw weight per person for pulled pork, since it loses a lot as it cooks.

Pork Shoulder: questions
What internal temperature should pork shoulder reach?
Pork is safe to eat at 63°C (145°F) with a rest, which suits sliced roast pork. For pulled pork, keep cooking to about 90–96°C (195–205°F) so the collagen melts and the meat shreds easily.
Is pork butt the same as pork shoulder?
Both come from the shoulder. Pork butt or Boston butt is the upper part above the shoulder blade and is more marbled, while picnic shoulder sits lower and often comes with skin. Either works for pulled pork.
How long does it take to cook pork shoulder?
Allow roughly 1.5–2 hours per kilo (40–60 minutes per pound) at 120–135°C (250–275°F) for barbecue-style pork. In a slow cooker, a 2 kg (4 lb) shoulder takes about 8–10 hours on low.
Why is my pulled pork tough?
It has not been cooked long enough. Pork shoulder gets tougher before it gets tender, so keep going until a fork twists through it with almost no resistance.
Should pork shoulder be fat side up or down?
In an oven or slow cooker, fat side up lets the melting fat baste the meat. In a smoker with heat coming from below, many pitmasters face the fat toward the heat to protect the meat.
Can you freeze pulled pork?
Yes. Cool it quickly, pack it with some of its cooking juices and freeze for up to 3 months. Reheat gently, covered, so it steams rather than dries.
