Pork Tenderloin Internal Temperature: FDA's 145°F Guideline

Updated: February 2026

Pork tenderloin is the leanest cut of pork, which makes it incredibly healthy but also prone to drying out if overcooked. Following the FDA's guideline of 145°F with a 3-minute rest is crucial for achieving juicy, tender results.

FDA Safe Temperature for Pork Tenderloin

💡 Pro Tip: Consider keeping a small log of issues and solutions – patterns often emerge over time.

The current FDA standard for whole pork cuts, including tenderloin, is 145°F internal temperature followed by a mandatory 3-minute rest . This replaced the outdated 160°F guideline and allows pork to remain moist while ensuring complete food safety.

Why Tenderloin is Different

Pork tenderloin is the most tender cut from the pig, located along the backbone. It contains minimal fat and connective tissue, which means:

It cooks faster than other pork cuts
It dries out rapidly if overcooked
It benefits enormously from precise temperature monitoring
It's unforgiving - even 10°F over target creates dry, tough meat

Using a reliable instant-read thermometer is essential for pork tenderloin success.

Cooking Times for Pork Tenderloin

Pork tenderloin typically weighs 1-1.5 pounds and is about 2-3 inches in diameter. Cooking times by method:

Roasting at 400°F: 20-25 minutes
Roasting at 425°F: 15-20 minutes
Grilling over medium-high direct heat: 15-20 minutes, turning every 5 minutes
Pan-searing then oven-finishing (375°F): 3-4 minutes searing + 10-12 minutes in oven
Sous vide at 140°F: 1.5-4 hours, then sear 1 minute per side
Air frying at 400°F: 18-22 minutes

Calculate approximately 15-20 minutes per pound at 400°F, but always verify with a thermometer.

Best Cooking Method: Sear + Roast

The optimal technique for pork tenderloin combines searing and roasting:

Step 1: Preheat oven to 400°F
Step 2: Sear tenderloin in an oven-safe skillet over high heat, 2-3 minutes per side until golden brown
Step 3: Transfer skillet to oven, roast 10-15 minutes until internal temperature reaches 145°F
Step 4: Remove from oven, rest 3-5 minutes

This method creates a flavorful crust while keeping the interior juicy.

Checking Temperature Correctly

Insert your instant-read thermometer into the thickest part of the tenderloin , typically the center. Pork tenderloin tapers at the ends, so those areas cook faster. The thick center is your target measurement point.

Check temperature in multiple spots if you're uncertain - one end may be 150°F while the center is only 140°F.

The Critical Rest Period

After reaching 145°F, remove tenderloin from heat and rest for at least 3 minutes (5-10 minutes is even better). During this time:

Internal temperature rises to 150-155°F (carryover cooking)
Juices redistribute throughout the meat
Proteins relax, improving tenderness
Continued heat ensures pathogen destruction

Cutting immediately causes significant juice loss. Tent loosely with foil during rest.

Why You'll See Pink

Pork tenderloin cooked to 145°F will have a pink center , and this is completely safe according to FDA guidelines. The color comes from myoglobin, a protein in muscle tissue, not from blood or undercooking. Trust your thermometer, not visual appearance.

Accounting for Carryover

Pork tenderloin's small diameter means rapid carryover cooking. The internal temperature can rise 10-15°F after removal from heat. Consider removing at 140°F and allowing it to coast to 145-150°F during rest. This requires experience and confidence - beginners should cook to 145°F before removal.

Avoiding Overcooking

Dry pork tenderloin results from exceeding 150-155°F. To prevent this:

Use an instant-read thermometer, not a dial thermometer
Check temperature starting at the minimum estimated time
Remove promptly when reaching 145°F
Don't "cook until done" - define "done" as 145°F
Consider brining for 30-60 minutes before cooking

Brining for Moisture Insurance

Pork tenderloin benefits significantly from brining. A simple brine:

1/4 cup kosher salt
1/4 cup sugar or brown sugar
1 quart water
Optional: herbs, garlic, peppercorns

Submerge tenderloin for 1-4 hours, rinse, pat dry, then cook. Brined pork retains moisture even if slightly overcooked.

Reverse Sear for Thick Tenderloins

For exceptionally thick tenderloins (over 3 inches diameter), try reverse searing:

Roast at 275°F until internal temp reaches 130-135°F
Sear in a screaming-hot cast iron pan, 1-2 minutes per side
Rest 5 minutes

This produces edge-to-edge pink meat with a caramelized crust.

Slicing for Maximum Tenderness

After resting, slice pork tenderloin against the grain (perpendicular to the muscle fibers) in 1/2-inch medallions. This shortens muscle fibers, maximizing tenderness.

Food Safety Notes

Pregnant women, children, elderly, and immunocompromised should consume pork cooked to at least 145°F
Don't eat rare or undercooked pork - unlike beef steaks, pork can harbor parasites throughout
Refrigerate cooked pork within 2 hours (1 hour if room temperature exceeds 90°F)
Store leftovers at 40°F or below, consume within 3-4 days
Reheat to 165°F

Common Mistakes to Avoid

Cooking to 160°F+ (outdated guideline, produces dry meat)
Not using a thermometer (guessing results in over/undercooking)
Cutting immediately without resting (juice loss)
Not accounting for carryover cooking (overcooks by 10-15°F)
Using the thin end for temperature measurement (reads too high)

Pork tenderloin cooked to 145°F with proper rest rivals any premium cut in tenderness and flavor. With a reliable thermometer and these FDA-approved techniques, dry pork becomes a problem of the past.
