how long do you cook a pork roast
A pork roast is done when it reaches an internal temperature of 145°F (63°C) for a traditional sliced roast, or up around 180–190°F (82–88°C) if you want it fall-apart tender, and the time it takes mainly depends on the cut, weight, and oven temperature.
Core timing guideline
- For a standard oven-roasted pork loin or leg at about 350–375°F (175–190°C), plan roughly 25–30 minutes per pound (about 55–65 minutes per kilogram), but always confirm with a meat thermometer rather than the clock.
- For a fattier pork shoulder/butt cooked to shreddable tenderness, expect about 2–4 hours total at 325–350°F (165–175°C), often working out to about 40 minutes per pound, until it is very tender and in the 180–190°F (82–88°C) internal range.
Simple step-by-step method
- Preheat the oven:
- Lean roast (loin/leg): 350–375°F (175–190°C).
- Shoulder for pulled-style: 325–350°F (165–175°C).
- Season and place in a roasting pan:
- Fat side up on a rack if possible so the juices baste the meat as it cooks.
- Roast by time as a rough guide:
- Lean roast: start checking after about 20–25 minutes per pound.
- Shoulder: plan 40 minutes per pound, checking earlier if your oven runs hot.
- Check internal temperature:
- Insert an instant-read thermometer into the thickest part, avoiding bone.
- For juicy slices: pull at 145°F (63°C), then rest 10–20 minutes.
- For pull-apart: continue to 180–190°F (82–88°C) until very tender.
- Rest the roast:
- Tent loosely with foil for 10–20 minutes so the meat stays moist and is easier to carve.
Quick reference table (oven-roasted)
| Cut | Oven temp | Approx. time | Target internal temp |
|---|---|---|---|
| Pork loin / leg (2–4 lb) | 350–375°F (175–190°C) | 25–30 min per lb | 145°F (63°C), then rest |
| Rolled pork loin (crackling) | Start 440–465°F (225–240°C) for 30–40 min, then 320–355°F (160–180°C) | 30–35 min per kg after initial blast | About 145–150°F (63–65°C) |
| Pork shoulder / butt | 325–350°F (165–175°C) | About 40 min per lb (2–4 hours total) | 180–190°F (82–88°C) for shreddable |
Safety and doneness tips
- Always prioritize internal temperature over minutes-per-pound, since roasts vary in shape and ovens vary in accuracy.
- Modern food-safety guidance treats 145°F (63°C) with a short rest as a safe minimum for whole pork roasts, giving a slightly pink, very juicy center.
- If the outside browns too fast before the center is done, loosely cover the roast with foil to prevent burning while it finishes cooking.
