Pork loin roasting time calculator

Roast pork loin by weight — to the modern USDA-safe 145°F that keeps it juicy, with the pull temperature and rest.

In short

A 3 lb pork loin at 325°F takes roughly 1–1¼ hours. For juicy results pull it around 138°F so it reaches 145°F after a 10–20 minute rest — the USDA-safe temperature since 2011, which leaves it faintly pink and tender.

About this estimate

This page locks the pork loin roasting time into the roasting calculator. Time is a planning estimate — oven calibration, shape, bone, and starting temperature all change it. The reliable test is a probe thermometer in the thickest part, away from bone: pull at temperature, not at the clock.

What temperature is pork loin done?
145°F with a 3-minute rest, the USDA minimum since 2011. At that temperature it's safe and juicy, often slightly pink — you no longer need to cook pork to 160°F.
How long does pork loin take per pound?
Roughly 20–25 minutes per pound at 325°F, but verify with a thermometer rather than relying on time.
