Pork Cooking Times Per Kg: Roast Chart & Guide

The Ultimate Guide to Pork Cooking Times per Kg: Say Goodbye to Dry Roasts

Few things are as disappointing as slicing into a gorgeous pork roast only to find it dry, tough, and completely devoid of moisture. On the flip side, undercooking pork used to be a major health concern, leading generations of home cooks to overcompensate by turning their roasts into leather.

Fortunately, modern culinary guidelines (backed by food safety standards) have changed the game. You no longer need to cook pork until it’s grey and dry. By mastering cooking times per kilogram and relying on internal temperature, you can achieve succulent, tender pork every single time.

The Golden Rule: Time is a Guide, Temperature is the Law

While calculating cooking time by weight is essential for planning your meal schedule, always verify doneness with a digital meat thermometer.

• Whole cuts (Loin, Chops, Tenderloin): Cook to an internal temperature of 63°C to 65°C (145°F to 149°F), followed by a mandatory 3-minute rest. This yields juicy, slightly blushing meat that is completely safe and infinitely tastier.
• Slow-cooking cuts (Shoulder, Butt, Belly): Cook to 88°C to 95°C (190°F to 203°F) to break down tough connective tissues for melt-in-your-mouth pulled pork.

Quick Reference: Cooking Times by Pork Cut

Different cuts demand entirely different cooking methods and timelines. Use the table below to map out your kitchen schedule.

| Cut of Pork | Oven Temperature | Cooking Time per Kg | Target Internal Temp | Best For |
| :— | :— | :— | :— | :— |
| Pork Loin Roast (Boneless or Bone-in) | 190°C (375°F) | 40 to 50 minutes per kg (plus 20 mins total) | 63°C – 65°C (145°F) | Traditional Sunday roasts, slicing |
| Pork Shoulder / Boston Butt | 150°C (300°F) | 70 to 90 minutes per kg | 90°C – 95°C (195°F) | Pulled pork, slow braising |
| Pork Belly | 180°C (350°F) | 50 to 60 minutes per kg | 75°C (165°F) | Crispy crackling, Asian-style braises |
| Pork Tenderloin | 200°C (400°F) | Best cooked by total time (~25-30 mins total) | 63°C (145°F) | Quick weeknight dinners |

Step-by-Step: How to Roast a Perfect Pork Loin

If you are working with a classic pork loin roast, follow this simple blueprint for success:

1. Bring to Room Temp: Take your pork out of the fridge 30 minutes before cooking. A room-temperature roast cooks much more evenly.
2. Score and Season: Score the fat cap in a diamond pattern if present. Rub generously with olive oil, sea salt, black pepper, garlic powder, and herbs like rosemary or sage.
3. Sear for Crust (Optional): Start the oven hot at 220°C (425°F) for the first 20 minutes to jumpstart a gorgeous outer crust, then drop it down to 190°C (375°F) for the remainder of the calculated time per kg.
4. Rest Before Slicing: Tent your pork loosely with foil and let it rest for 10 to 15 minutes. This allows the muscle fibers to relax and the juices to redistribute evenly throughout the roast rather than spilling onto the cutting board.
