What Temperature Do You Cook Pork Tenderloin To
Pork tenderloin reaches its best texture when the internal temperature hits the right number, and pulling it from the oven at precisely 145°F keeps it juicy. So what temperature do you cook pork tenderloin to? The answer is 145°F for safe, tender, slightly pink pork. That single number changes everything about how this lean cut turns out.
Get it right and you get a soft, sliceable roast. Get it wrong and you get dry, chewy meat. This guide breaks down the exact temps, resting times, and simple steps so you nail it every time.
What Temperature Do You Cook Pork Tenderloin To
The USDA recommends a minimum internal temperature of 145°F (63°C) for pork, followed by a 3-minute rest. This applies to pork tenderloin, pork chops, and roasts. Modern guidelines dropped the old 160°F rule years ago because it made pork tough and dry.
At 145°F, pork is safe to eat and still has a light pink center. That blush of color is normal and not a sign of undercooking. The rest period lets the temperature hold steady long enough to kill any harmful bacteria.
Why 145°F Is The Magic Number
Pork tenderloin is a lean cut with very little fat. Fat usually keeps meat moist during cooking. Since tenderloin lacks it, you rely on temperature control instead.
- At 145°F, the muscle fibers are just cooked through and still hold moisture.
- Above 160°F, the fibers squeeze out water fast, and the meat turns dry.
- The 3-minute rest brings the temp to a safe, stable level.
Some cooks prefer 140°F for a rosier center, but 145°F is the safe, reliable target for home kitchens.
Ideal Temperature Range At A Glance
- 140°F to 145°F: medium-rare to medium, juicy and tender
- 150°F to 155°F: medium-well, slightly firmer
- 160°F and up: well done, dry and chewy
Aim for 145°F. That is the sweet spot between safety and flavor.
How To Cook Pork Tenderloin To 145°F
Reaching the right temp is about method and monitoring. Here is a simple plan that works for oven roasting, the most common approach.
Step-By-Step Oven Method
- Preheat your oven to 425°F. A hot oven gives a quick sear and keeps the inside juicy.
- Pat the tenderloin dry with paper towels. Dry meat browns better.
- Season with salt, pepper, and any herbs or spices you like.
- Heat an oven-safe skillet over medium-high heat with a little oil.
- Sear the tenderloin for 2 to 3 minutes per side until browned.
- Move the skillet to the oven and roast for 12 to 15 minutes.
- Check the internal temp with a digital thermometer at the thickest part.
- Pull it out when it reads 145°F.
- Let it rest on a cutting board for 3 to 5 minutes before slicing.
Total cook time is usually 15 to 20 minutes for a 1-pound tenderloin. Smaller pieces cook faster, so always trust the thermometer over the clock.
Other Cooking Methods And Their Temps
The target stays 145°F no matter how you cook it. Only the time and technique change.
- Grilling: sear over high heat, then move to indirect heat until 145°F.
- Pan-searing: cook on the stovetop, turning often, until 145°F.
- Sous vide: set the water bath to 145°F and cook for 1 to 3 hours.
- Air fryer: cook at 400°F for 15 to 18 minutes, checking early.
No matter the method, the number to hit is the same.
Tools And Tips For Perfect Results
You cannot guess this temp by look or touch. A good thermometer is the one tool you really need.
Use A Digital Meat Thermometer
An instant-read digital thermometer gives you a fast, accurate reading. Insert the probe into the thickest part of the meat, away from any fat or bone. Wait for the number to settle before you decide.
- Check the temp near the end of cooking, not just at the start.
- Test the center, not the thin tail end.
- Clean the probe between checks.
Always Rest The Meat
Resting is not optional. During the rest, the juices redistribute through the meat. Cut too soon and those juices run onto the board instead of staying in your slice.
Three to five minutes is enough for a tenderloin. Cover it loosely with foil if you want, but keep it short so it does not keep cooking.
Common Mistakes To Avoid
- Cooking to 160°F out of old habit, which dries out the pork.
- Skipping the rest and losing all the juice.
- Walking away without checking the temp often.
- Using a slow, low oven that overcooks the outside before the inside is ready.
- Forgetting that the temp keeps rising a few degrees after you pull it.
Pull the meat at 145°F and let carryover heat do the rest. If you wait until 150°F in the oven, it may climb higher than you want.
Storing And Reheating Leftovers
Leftover pork tenderloin keeps in the fridge for 3 to 4 days in a sealed container. Reheat it gently to avoid drying it out further.
- Reheat in a covered pan with a splash of broth over low heat.
- Or microwave in short bursts until just warm.
- Avoid high heat, which toughens the meat.
Cold slices also work great in sandwiches and salads, so you do not have to reheat at all.
Final Word On Pork Tenderloin Temperature
Cook pork tenderloin to 145°F and rest it for 3 minutes. That is the whole rule. It keeps the meat safe, juicy, and tender with a slight pink center that is perfectly fine to eat.
Use a digital thermometer, pull it at the right number, and let it rest. Do that and your pork tenderloin will come out right every single time.
