What Temperature To Cook Pork Tenderloin
Pork tenderloin is lean and cooks quickly, so hitting the right temperature is key to keeping it moist. If you are wondering what temperature to cook pork tenderloin, the answer is simple: pull it from the oven at 145°F. That single number is the difference between juicy slices and a dry, chewy roast.
This guide breaks down the exact temps, times, and steps you need. You will also learn how resting and carryover cooking affect the final result.
The Correct Internal Temperature For Pork Tenderloin
The USDA updated its guidance years ago, and it changed how we cook pork. Whole cuts like tenderloin are safe at 145°F with a three-minute rest.
That is lower than the 160°F many people grew up with. The old number was based on fear of trichinosis, which is now rare in commercial pork.
- Target pull temperature: 145°F
- Rest time: 3 minutes minimum
- Result: Slightly pink, juicy center
If you prefer no pink at all, cook to 150°F. Just know the meat gets a bit firmer with every extra degree.
What Temperature To Cook Pork Tenderloin
Oven temperature and meat temperature are two different things. Set your oven to 425°F for a fast roast, or 350°F for a slower, more forgiving cook.
Oven Temperature Options
- 425°F: 20 to 25 minutes, best for weeknights
- 400°F: 22 to 27 minutes, good browning
- 350°F: 30 to 35 minutes, even cooking edge to center
No matter which you pick, the meat still comes out at 145°F. The oven temp only changes how fast you get there.
Why Carryover Cooking Matters
Meat keeps cooking after it leaves the oven. The internal temp can rise 5 to 10 degrees while it rests.
So if you wait until the thermometer reads 145°F in the oven, you may end up at 155°F on the plate. Pull it at 140°F to 142°F and let the rest finish the job.
Step-By-Step Cooking Method
Follow these steps for a tenderloin that is moist every time.
- Preheat your oven to 425°F. Place a rack in the middle position.
- Pat the tenderloin dry with paper towels. Trim any silver skin.
- Rub with oil, salt, pepper, and any herbs you like.
- Sear in an oven-safe skillet over high heat, 2 minutes per side.
- Transfer the skillet to the oven. Roast for 18 to 22 minutes.
- Check the temp at 15 minutes with an instant-read thermometer.
- Pull at 140°F to 142°F. Tent with foil and rest 5 minutes.
- Slice against the grain into half-inch medallions.
Total time from fridge to plate is about 35 minutes. That makes this one of the fastest cuts of pork you can cook.
Grilling And Pan-Searing Temps
You do not need an oven for great results. Other methods work just as well, and the target temp never changes.
Grill Temperature
Set up a two-zone fire. Sear over high heat for 2 minutes per side, then move to indirect heat.
- Grill temp: 400°F to 450°F over direct heat
- Indirect side: 350°F
- Total time: 15 to 20 minutes
- Pull at: 140°F
Stovetop Searing
A cast iron pan gives you a deep crust in minutes. Sear 3 minutes per side, then finish in a 400°F oven for 8 to 10 minutes.
This method is great for a small tenderloin that would dry out in a long roast.
How To Check The Temperature
An instant-read thermometer is the only reliable tool here. Timers lie, ovens run hot or cold, and tenderloins vary in size.
- Insert the probe into the thickest part
- Avoid touching bone or the pan bottom
- Check in two spots to be sure
- Wait 10 seconds for a stable reading
If you do not own a thermometer, buy one. It costs less than one ruined dinner and it works for chicken, steak, and bread too.
Signs The Pork Is Done Without A Thermometer
You can guess, but it is risky. The meat should feel firm but still give slightly when pressed. Juices should run clear with a hint of pink.
If the outside is browned and the center is still soft, it likely needs a few more minutes. These clues help, but they are not precise.
Common Mistakes That Dry Out Pork Tenderloin
Most dry tenderloin comes down to a few repeat errors. Avoid these and your results improve right away.
- Cooking to 160°F because of old advice
- Skipping the rest and slicing right away
- Using a baking dish instead of a skillet or sheet pan
- Overcooking because the recipe time was too long
- Not trimming silver skin, which turns tough
The biggest one is the rest. Cutting early lets all the juice run onto the board instead of staying in the meat.
Resting, Slicing, And Serving
Rest the meat for 5 minutes under loose foil. This lets the juices redistribute and the temp climb to a safe 145°F.
Slice against the grain. On a tenderloin, the grain runs lengthwise, so cut crosswise into rounds. Thick slices stay juicier than thin ones.
Serve with roasted potatoes, green beans, or a simple pan sauce made from the drippings. Leftovers keep in the fridge for three days.
Final Numbers To Remember
Here is the short version you can tape inside a cabinet door.
- Oven temp: 425°F
- Pull temp: 140°F to 142°F
- Final temp after rest: 145°F
- Rest time: 3 to 5 minutes
- Roast time: 18 to 25 minutes
Pork tenderloin rewards a light touch. Cook it hot, pull it early, and let it rest. Do that and you will get tender, slightly pink slices every single time.
