Pork Cuts Guide: From Tenderloin to Belly
Pork spans a bigger fat range than any other common meat — from 3 g per 100 g in the tenderloin to 35 g in the belly. That means the cut dictates both the cooking method and the meal.
The cuts
| Cut | Fat | Best for | Notes |
|---|---|---|---|
| Tenderloin | ~3 g / 100g | Fast roasting, medallions | Leanest pork cut. Pull at 140°F, rest to 145°F. |
| Loin (roast or chop) | ~7 g / 100g | Roasts, brined chops | Easy to overcook. Brine 4+ hours for juicy chops. |
| Sirloin | ~7 g / 100g | Kebabs, weeknight roasts | Leaner than loin, more flavor than tenderloin. |
| Shoulder / Boston butt | ~20 g / 100g | Pulled pork, carnitas, ragu | Collagen breaks down at 195–205°F. Long, low, done. |
| Belly | ~35 g / 100g | Bacon, porchetta, braised belly | Half fat by weight. Braise then crisp. |
| Ribs (baby back) | ~15 g / 100g | Smoking, oven ribs | Tender, less meat than spare ribs. |
| Ribs (spare / St. Louis) | ~20 g / 100g | Low-and-slow BBQ | More meat and fat than baby backs — richer result. |
| Ham (fresh) | ~10 g / 100g | Roasts | Not cured. Long roast to 145°F. |
Two families: fast and slow
Loin cuts (tenderloin, loin roast, chops, sirloin) are lean and want fast cooking to a specific temperature. Overshoot and they turn to sawdust.
Shoulder and belly are loaded with fat and collagen. They want the opposite: hours at low temperature until the connective tissue melts into gelatin. You can't overcook them the same way — they just get more tender.
The 145°F change
The USDA lowered the safe pork temperature from 160°F to 145°F in 2011. Modern pork is trichinosis-free, so pink pork at 145°F is safe and juicy. If your recipe still says 160°F, it's outdated.
Buying tips
- Color should be pinkish-red, not grey or dark red (dark = old or bruised).
- Fat should be white, firm, and dry — yellow or soft fat means age.
- "Enhanced" pork (labeled: contains up to X% solution) is pre-brined. Skip your own brine.
- Heritage breeds (Berkshire, Duroc, Mangalitsa) have more marbling and cost more — worth it for chops and roasts, wasted on braises.
Weekend project: pulled pork
Buy a 6–8 lb bone-in Boston butt. Rub, smoke or oven-roast at 225°F for 8–10 hours until the internal temp hits 203°F and a probe slides in like warm butter. Rest 30 minutes, pull, sauce lightly. Feeds 10 with leftovers.
