What Temperature Should You Cook Pork Loin To?
The ideal internal temperature for cooking pork loin is between 145°F (medium) and 150°F (medium-well) followed by a short rest. This ensures a safe, tender, and juicy result.
Understanding Pork Loin: A Culinary Foundation
Pork loin is a lean and versatile cut of meat from the pig’s back, running from the shoulder to the hip. Unlike the fattier pork belly or shoulder, loin requires a bit more attention during cooking to prevent it from becoming dry. When cooked correctly, it offers a delicious and healthy protein option. Understanding its composition is the first step to achieving perfect results.
Why Temperature Matters for Pork Loin
Precise temperature control is crucial for pork loin. Overcooking leads to dryness and toughness, while undercooking poses a health risk. The USDA recommends a minimum internal temperature of 145°F (63°C) for safe pork consumption. However, achieving optimal tenderness and juiciness requires careful monitoring and removal from the heat at the right moment. A reliable meat thermometer is your best friend in this culinary endeavor.
The Ideal Cooking Process for Pork Loin
Here’s a step-by-step guide to cooking a perfect pork loin:
- Preparation: Pat the pork loin dry with paper towels. This allows for better browning and seasoning adhesion.
- Seasoning: Generously season the loin with salt, pepper, and your favorite herbs and spices. Consider a dry rub or a marinade for added flavor.
- Searing (Optional but Recommended): Sear the pork loin on all sides in a hot pan with oil or butter. This creates a flavorful crust and helps seal in the juices.
- Cooking Method: Choose your preferred method:
- Oven Roasting: Place the seared (or unseared) pork loin in a roasting pan. Roast at 325°F (163°C) until the internal temperature reaches 140°F (60°C) for medium-rare, 145°F (63°C) for medium, or 150°F (66°C) for medium-well.
- Grilling: Grill the pork loin over medium heat, turning frequently, until the internal temperature reaches the desired level.
- Slow Cooking (Not Recommended for Unbrined Loin): Due to its lean nature, pork loin is best when prepared with a dry rub or brining prior to slow cooking.
- Temperature Monitoring: Use a meat thermometer inserted into the thickest part of the loin to monitor the internal temperature. Avoid touching bone.
- Resting: Remove the pork loin from the heat and let it rest for at least 10 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful final product. Tent with foil while resting.
- Slicing: Slice the pork loin against the grain for maximum tenderness.
Common Mistakes to Avoid When Cooking Pork Loin
- Overcooking: This is the most common mistake. Use a thermometer!
- Not Resting: Skipping the resting period leads to dry pork as the juices escape when sliced.
- Insufficient Seasoning: Pork loin benefits from generous seasoning.
- Using the Wrong Cut: Ensure you’re using a pork loin, not a pork tenderloin, which cooks differently. Pork tenderloin is smaller and more delicate.
- High Cooking Temperatures: Using higher temperatures than suggested can result in uneven cooking and dryness. Slow and steady is best.

Frequently Asked Questions About Cooking Pork Loin
What type of thermometer is best for cooking pork loin?
An instant-read thermometer is ideal for quickly and accurately checking the internal temperature of your pork loin. Digital thermometers are generally more precise than analog ones. Avoid using the pop-up thermometers that sometimes come with roasts, as they are often inaccurate.
Should I sear the pork loin before roasting?
Searing is optional but highly recommended. It creates a beautiful crust and adds depth of flavor. Sear it over high heat in a pan with oil or butter before transferring it to the oven.
How long should I rest the pork loin after cooking?
Rest the pork loin for at least 10 minutes after cooking. Longer resting times (up to 20 minutes) are even better. Tent it loosely with foil to keep it warm.
Can I cook pork loin in a slow cooker?
While possible, slow cooking pork loin without proper preparation can often result in dry meat. Consider brining the pork loin for a few hours before slow cooking or using a dry rub. Slow cooking at a low temperature (around 250°F) for about 4-6 hours can work, but monitoring the internal temperature is still essential.
How do I prevent my pork loin from drying out?
The key to preventing dryness is avoiding overcooking. Use a meat thermometer and remove the pork loin from the heat when it reaches the target temperature. Resting the meat is also critical for moisture retention. Searing and/or brining before cooking also help.
What’s the difference between pork loin and pork tenderloin?
Pork loin and pork tenderloin are different cuts of meat. Pork loin is a larger, wider cut from the back of the pig, while pork tenderloin is a smaller, narrower cut from the loin muscle. They require different cooking times and methods.
What are some good seasonings for pork loin?
Pork loin is versatile and pairs well with a variety of seasonings. Popular options include salt, pepper, garlic powder, onion powder, paprika, rosemary, thyme, sage, and Dijon mustard. Experiment with different combinations to find your favorite flavor profile. A simple dry rub made with brown sugar, salt, paprika, garlic powder, and onion powder is also a great choice.
Can I freeze cooked pork loin?
Yes, cooked pork loin can be frozen. Allow it to cool completely, then wrap it tightly in plastic wrap and place it in a freezer-safe bag. It can be stored in the freezer for up to 2-3 months. Thaw it in the refrigerator overnight before reheating.
How do I reheat cooked pork loin without drying it out?
To reheat pork loin without drying it out, wrap it in foil with a little broth or water and heat it in a low oven (around 300°F) until warmed through. You can also slice it and add it to sauces or soups.
What are some good side dishes to serve with pork loin?
Pork loin pairs well with a variety of side dishes, including roasted vegetables, mashed potatoes, rice pilaf, green beans, applesauce, and cranberry sauce.
Is pink pork safe to eat?
Yes, slightly pink pork is safe to eat if it has reached an internal temperature of 145°F. The USDA revised its guidelines to reflect this.
What is brining, and should I brine my pork loin?
Brining involves soaking the pork loin in a saltwater solution (sometimes with added sugar, herbs, and spices) before cooking. Brining can help the pork retain moisture and improve its flavor. It’s highly recommended for lean cuts like pork loin, especially if you plan to grill or slow cook it.
