Master the Roast: The Ultimate Guide to Pork Cooking Times per KG

There is an art to cooking pork. Too often, people overcompensate for outdated food safety myths by cooking pork until it resembles shoe leather. On the flip side, getting the timing just right unlocks a world of succulent meat, crackling golden skin, and incredible flavor.

Because pork cuts vary dramatically in fat content, muscle structure, and collagen, a one-size-fits-all approach doesn’t work. The secret to perfection lies in understanding cooking times per kilogram (kg) paired with the ultimate tool: a meat thermometer.

1. Pork Cooking Times by Cut (Per KG)

When roasting pork, your timing will depend heavily on the specific cut you are putting into the oven. Most joints are cooked at an oven temperature of 170°C to 180°C (340°F to 350°F) unless you are slow-roasting.

| Pork Cut | Recommended Oven Temp | Cooking Time per KG | Notes |
| :— | :— | :— | :— |
| Pork Loin (Boneless or Bone-in) | 180°C (350°F) | 40 to 45 mins per kg (+ 20 mins extra) | Lean cut; easy to dry out if overcooked. |
| Pork Belly | 180°C (350°F) | 45 to 50 mins per kg (+ 30 mins extra) | High fat content; benefits from high heat at the end for crackling. |
| Pork Shoulder (Boston Butt / Picnic) | 160°C to 170°C (325°F to 340°F) | 60 to 75 mins per kg (or 3–4 hours total for a 2–3kg joint) | Packed with connective tissue; needs a slower, longer cook to break down. |
| Fresh Leg / Uncured Ham | 170°C (340°F) | 40 to 50 mins per kg | Large, dense joint; baste regularly to retain moisture. |
| Pork Tenderloin | 200°C (400°F) | 20 to 25 mins total (Sear first) | Very lean; best roasted quickly at high heat. |
