Pork Cooking Times Per Kg: Ultimate Roast Chart

Mastering Pork Cooking Times per KG: The Ultimate Guide

Getting pork right comes down to balancing two things: rendering the fat to build incredible flavor and keeping the lean meat from drying out. Because different cuts have unique fat distributions and muscle densities, a one-size-fits-all approach does not work.

The Golden Calculation for Roasting

For standard lean-to-medium cuts like a pork loin, leg, or rack, the standard oven calculation at 180°C is:

40 to 45 minutes per kg, plus an extra 20 to 30 minutes total cooking time.

If you are aiming for a crackling skin on a pork loin or belly, a classic technique is to start the oven hot at 220°C for the first 30 minutes, then drop it down to 180°C for the remainder of the calculated time.

Cooking Times by Popular Cut

Different cuts require entirely different treatment depending on whether you want a neat sliced roast or fall-apart pulled meat.

| Cut | Oven Temperature | Time per KG / Guide | Target Internal Temp |
| :— | :— | :— | :— |
| Pork Loin / Leg (Boneless or Bone-in) | 180°C | 40–45 mins per kg + 20 mins | 65°C – 70°C |
| Pork Belly | 180°C | 45 mins per kg + 20 mins | 72°C |
| Pork Shoulder (Slow Roast / Pulled) | 160°C – 170°C | 60–75 mins per kg (or 3 hours fixed for a 1.5–2 kg piece) | 90°C – 95°C |
| Pork Tenderloin | 200°C | 20–25 minutes total (fast roast) | 65°C |

Note: Heavy cuts like shoulder have plenty of connective tissue and fat, meaning they actually need longer, slower cooking times to break down completely.

Key Rules for Success

• Invest in a meat thermometer: Visual cues can deceive you. Insert a digital probe into the thickest part of the meat (avoiding bone) to check the internal temperature accurately.
• Let it rest: Always let your roast rest loosely under foil for 15 to 20 minutes before carving. This allows the hot muscle fibers to relax and reabsorb the juices rather than spilling out onto your cutting board.
• Prep the skin: If working with skin-on cuts like belly or shoulder, score the rind deeply, pat it completely dry with paper towels, and rub coarse salt into the cuts to draw out moisture for maximum crunch.
