How long does pork take to roast per kilogram?

The standard formula is 30 minutes per 500g plus 30 minutes at 180°C fan (200°C conventional). So a 1.5kg joint takes about 120 minutes (2 hours). Pork must always be cooked through to an internal temperature of at least 70°C. Unlike beef and lamb, pink pork is not safe to eat.

How do I get good crackling?

For perfect crackling: score the skin deeply with a sharp knife at 1cm intervals (ask your butcher to do this). Pat the skin completely dry, then rub with oil and plenty of fine salt. Start the oven at 220°C for 25-30 minutes until the skin puffs and crackles, then reduce to 180°C for the remaining time. Do not baste the skin or cover with foil — moisture is the enemy of crackling.

Which pork cuts are best for roasting?

Loin (bone-in or boneless) is the classic roasting cut with excellent crackling potential. Shoulder is fattier and ideal for slow roasting — it shreds beautifully when cooked low and slow. Belly produces the most crackling but is very fatty. Leg is leaner and serves a crowd but can dry out if overcooked. For a smaller household, a mini loin roast (500g-1kg) is perfect.

Can pork be served pink?

In the UK, the official guidance is that pork should be cooked through to 70°C internally. While some chefs now serve premium pork (like Iberico or heritage breeds) slightly pink, this is a professional kitchen practice. For home cooking, always ensure pork is cooked through — use a meat thermometer to check the thickest part reaches 70°C.

What goes well with roast pork?

Classic accompaniments include apple sauce, sage and onion stuffing, roast potatoes, and seasonal vegetables. Gravy made from the pan juices is essential. Mustard (English or wholegrain) is traditional. For a more modern twist, try roast pork with fennel, or Asian-inspired flavours like five-spice and honey.

How We Calculate This

This calculator uses the standard UK pork roasting formula: 30 minutes per 500g plus 30 minutes extra, at 180°C fan (200°C conventional). Pork must always be cooked through to a minimum internal temperature of 70°C for food safety.

Resting time is calculated at 1 minute per 100g, with a minimum of 15 minutes and maximum of 30 minutes. Serving estimates are based on approximately 300g of raw bone-in pork per person.
