Pork is the world’s favorite meat, exceeding mutton, beef, and even poultry in per capita consumption. How much of that meat, though, is overcooked? Have you ever had a dry pork roast or tough chops? I’m sure you have. People used to—and unfortunately still do—overcook many pork products. They don’t know that the USDA says whole pork cuts should be cooked at 145°F and should rest for three minutes afterward.
Pork loin is a lean, tender cut that takes beautifully to roasting, grilling, smoking and more. But like any meat, monitoring the internal temperature is the only sure way to know when it’s perfectly cooked. This guide will cover everything you need for getting pork loin to the right doneness, including proper finishing temps, use of a meat thermometer, carryover cooking and more.
Why Temperature Trumps Time When Cooking Pork Loin
Many beginning cooks go by recommended cooking times when roasting pork loin or other meats. But relying solely on the clock can lead to inconsistent results. Timing is unreliable because there are too many variables:
- Thickness and shape of the cut
- Bone-in vs boneless
- Cooking method (roasting, grilling, etc)
- Your oven/grill temperature accuracy
- Altitude
This means that cooking time cannot guarantee the interior has reached the proper safe finishing temperature. The thermometer doesn’t lie – use it every time for foolproof doneness.
USDA Minimum Internal Temperature for Pork
The USDA states pork should reach a minimum internal temperature of 145°F with a 3 minute rest time. Any lower risks potential foodborne illness.
Ground pork or pork sausage must hit 160°F since pathogens can spread throughout the meat during grinding
For whole cuts like pork loin, 145° is the USDA baseline But most chefs recommend 150-155°F for ideal juiciness, flavor and texture.
Recommended Pork Loin Temperatures for Doneness
Here are the finishing internal temperatures for different levels of doneness when cooking a pork loin roast or chop:
- Medium Rare – NOT recommended by USDA, do not eat below 145°F
- Medium – 150°F
- Medium Well – 155°F
- Well Done – 160°F+
Medium (150°F) provides the best balance of safety with a slight hint of pink juiciness Bone-in cuts can go up to 155°F since the bone insulates the meat
How to Tell Pork Loin Doneness Without a Thermometer
With experience, you can gauge doneness through a few visual tests:
-
Press the thickest part – it should feel firm but with a slight bounce back. If too mushy, it’s underdone.
-
Check the meat’s inner color when cutting into the center. Light pink = medium. Very faint pink = medium well. No pink at all = well done.
-
Clear juices are a sign it’s finished cooking. If still reddish, needs more time.
But even skilled chefs revert to the thermometer for a precise reading. Get in the habit of using one for foolproof results.
Accounting for Carryover Cooking When Roasting Pork Loin
It’s crucial to know a roast’s temperature will continue rising 5-10°F during the rest time after removing from the oven or grill. This carryover cooking occurs as residual heat evenly distributes through the meat.
To allow for carryover:
-
Roast until it’s 5-10°F BELOW your target finish temperature.
-
For example, if aiming for 150°F, roast until the loin reaches 140-145°F.
-
After resting, it will coast up to 150°F+ for medium doneness.
-
For food safety, do not let it rise above 155°F during resting.
Bone-In vs Boneless Pork Loin Temps
A boneless loin roast needs monitoring since heat can penetrate from all sides. Shoot for 150°F (medium) as the final post-resting temp.
Bone-in loin roasts can be safely cooked to 155°F since the bone insulates the meat and slows cooking. Check in multiple spots to be sure.
Chops can be cooked to higher temps since they are thinner. Cook until just slightly pink for best moisture.
Probing Pork Loin Correctly
-
Always use an instant-read digital thermometer for accuracy.
-
Insert deep into the thickest part of the roast, away from any bones.
-
For long roasts, check temperature in a few different areas. Look for consistent readings.
-
For chops, insert into the meatiest side, angling toward the center.
-
Make sure the probe isn’t touching any bone, fat or the cooking vessel.
Resting Pork Loin After Cooking
Pork doesn’t need as long a rest as beef or lamb. Rest loin roast for 5 minutes tented in foil before slicing or serving. This allows juices to redistribute through the meat.
Chops can be rested for just 2-3 minutes before serving. Resist cutting into the meat right away or juices will spill out.
Is It Safe to Eat Pork That’s Still Pink?
Today’s pork is very lean, so some interior pinkness when cooked to medium doneness is normal. The key is reaching a minimum safe temperature of 145-150°F to kill potential bacteria.
Touching the meat and looking for clear juices are good ways to double check for doneness. Trust your thermometer and enjoy pork with a hint of pink.
How Long to Cook Pork Loin Roast at 350°F
As a very general guideline, a 3 lb boneless roast takes about 1 hour 15 minutes at 350°F to reach 150°F. A bone-in roast may need up to 1 hour 30 minutes.
But many factors affect exact cooking time. Use the thermometer as your guide and allow the pork loin to rest before serving.
Pork Loin Pasteurization Time To Kill Bacteria
In addition to reaching 145°F, the USDA endorses a “pasteurization” time guideline to fully kill potentially harmful bacteria.
Pork must be held at 140°F for at least 10 minutes before becoming safe to eat. This ensures any pathogens are neutralized throughout the meat.
So cooking low and slow aids pasteurization compared to a hotter/faster roast. But reaching 145°F+ is most critical.
Key Takeaways for Cooking Pork Loin Properly
Follow these tips for perfect pork loin every time:
-
Always cook to a minimum safe temperature of 145°F.
-
For ideal juiciness and flavor, target 150-155°F after resting.
-
Rely on an instant read thermometer for accuracy – don’t go by time alone.
-
Allow for carryover cooking by removing 5-10°F before final target temp.
-
Let rest at least 5 minutes before slicing to allow juices to redistribute.
Mastering the right internal temperature is the best way to nail tender, moist pork loin with a hint of pink that is always safe to enjoy.
Advances in Raising Livestock Prompted Change in Recommended Pork Temperature
America has been worried about the amount of fat in their food since the 1970s. Since then, pork has been bred to be leaner and leaner. Cuts that used to have lots of tasty fat on them are now almost all lean, but the belly still has fat streaks for bacon. Most common cuts of pork are about 7% leaner now than they were five years ago, and the amount of saturated fat has dropped by 27% during the same time period. In fact, pork tenderloin is now as lean as a skinless chicken breast.
Unfortunately, this has made food taste worse because less fat means less flavor and makes it easier for meat to dry out while cooking, making a roast more likely to be bland and dry. Heritage breeds and cuts that are high in fatty marbling can still be bought, but they are hard to find and cost a lot. So the changes in pig breeding and farming made cooking pork to the formerly-recommended temperature unsavory.
While this change in pork breeding was taking place, farmers were also revising their feeding practices.
Modern grain-fed pigs are so much safer to eat that the USDA changed the cooking recommendation for pork. They also changed how they were bred and fed, which made the pork leaner and more likely to dry out. However, the temperature can handle that leanness better now.
Background for new pork cooking temperature
Research performed by the National Pork Board has found that most at-home chefs have a tendency to overcook common cuts of pork, for fear of serving unsafe, undercooked pork. There is good reason for your grandmother cooking pork until it well-resembled shoe leather. Before the introduction of much more modern farming and feeding practices, undercooked pork was a source of the disease trichinosis—the gateway to a potential health disaster that no one wants to deal with. Cooking pork to a high temperature eliminated that risk. Until 2012, the recommended doneness temperature for pork was 160°F (71°C). However, advancements in hog farming have necessitated a change in the temperature recommendations.
