The USDA recommends cooking pork loin to an internal temperature of 145°F (63°C), followed by a 3-minute rest time. This is the safest and most reliable way to ensure your pork is both safe to eat and deliciously juicy.
Why Cooking Temperature Matters
Undercooked pork can harbor harmful bacteria like Salmonella and Trichinella, leading to food poisoning. Overcooked pork becomes dry and tough. Using a meat thermometer is essential for accuracy—never rely on appearance alone.
USDA Pork Loin Cooking Temperature Guidelines
Doneness Level | Internal Temperature | Description |
---|---|---|
Safe Minimum | 145°F (63°C) + 3 min rest | Perfectly cooked, juicy, and safe to eat |
Medium Well | 150-155°F | Firmer texture, still moist |
Well Done | 160°F+ | Fully cooked but may be dry |

How to Measure Temperature Correctly
Insert the thermometer into the thickest part of the pork loin, avoiding bone or fat. Wait for the reading to stabilize. Always verify temperature at multiple points for accuracy.
Spice Hacks for Flavorful Pork Loin
While temperature is critical for safety, these techniques enhance flavor without compromising quality:
Dry Rub for Depth
Combine smoked paprika, garlic powder, brown sugar, salt, and black pepper. Massage into meat and refrigerate 4+ hours for optimal flavor penetration.

Citrus Zest for Brightness
Add fresh lemon or orange zest to your rub to balance richness and prevent overpowering spices.
Smart Spice Storage Tips
- Airtight Containers: Store ground spices in sealed glass jars away from heat and light.
- Cool & Dark Storage: Keep spices in a pantry or drawer, not near the stove.
- Label & Date: Replace ground spices every 6 months for peak freshness.
