What Temp to Cook a Pork Tenderloin Pork tenderloin cooks best to an internal temperature of 145°F (63°C), followed by a 3-minute rest for juicy, safe results. This USDA guideline keeps it tender without drying out the lean meat.

Oven Cooking Guide

Bake at 375-425°F for even cooking; time varies by size (20-30 minutes typically).

  • Preheat oven and use a meat thermometer in the thickest part.
  • Sear first on stovetop for flavor, then finish in oven until 145°F.
  • Let rest tented in foil to redistribute juices.

Why 145°F Internal?

Modern pork is safe at this temp, killing pathogens while staying pink and moist—unlike the old 160°F rule. Higher hits 155-160°F for no pink, but risks toughness.

Method| Oven Temp| Internal Target| Approx. Time (1-1.5 lb)
---|---|---|---
Roast| 400°F| 145°F| 20-25 min 3
High-Heat Sear + Oven| 425°F| 145°F| 15 min 2
Low-Slow| 350°F| 145°F| 25-30 min 1

Pro Tips from Chefs & Forums

Trim silver skin to avoid chewiness; season simply with salt, pepper, herbs. Reddit chefs stress brining or yogurt marinade for extra juiciness: "Sous vide at 140°F then sear." Avoid overcooking—lean cuts dry fast.

TL;DR: Aim for 145°F internal; rest 3 min. Use thermometer always.
