How Long Should You Cook a Pork Loin?
The ideal cooking time for a pork loin depends on the cooking method and the target internal temperature. Generally, you should aim for an internal temperature of 145°F (63°C) for medium and cook it for approximately 20-25 minutes per pound at 350°F (175°C).
Understanding Pork Loin: A Cut Above the Rest
Pork loin is a lean and flavorful cut of meat taken from the back of the pig, running from the shoulder to the hip. It’s often confused with pork tenderloin, but they are distinct cuts. Loin is wider and flatter, allowing for even cooking, while tenderloin is smaller and more tender. Pork loin offers a versatile canvas for various cooking methods, from roasting and grilling to pan-searing. Its mild flavor profile readily absorbs marinades and seasonings, making it a favorite for both novice and experienced cooks.

The Cooking Process: Step-by-Step
Here’s a basic guide to roasting a pork loin:
- Preparation: Preheat your oven to 350°F (175°C). Pat the pork loin dry with paper towels.
- Seasoning: Generously season the pork loin with salt, pepper, and any desired herbs and spices. A simple rub of garlic powder, onion powder, and paprika works well.
- Searing (Optional): Sear the pork loin on all sides in a hot skillet with oil to develop a flavorful crust. This step is not essential, but it adds depth of flavor.
- Roasting: Place the pork loin in a roasting pan. Use a rack within the pan to allow for even heat circulation.
- Temperature Monitoring: Insert a meat thermometer into the thickest part of the loin, being careful not to touch bone.
- Cooking Time: Roast for approximately 20-25 minutes per pound, or until the internal temperature reaches 145°F (63°C) for medium.
- Resting: Remove the pork loin from the oven 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. Cover loosely with foil while resting.
Cooking Methods Compared: Time and Temperature
The cooking method greatly influences the cooking time required for pork loin.
| Cooking Method | Temperature | Approximate Time | Notes |
|---|---|---|---|
| Roasting | 350°F (175°C) | 20-25 minutes per pound | Ideal for even cooking and tender results. |
| Grilling | Medium-High Heat (375-450°F) | 15-20 minutes total | Requires constant monitoring to prevent burning; sear first for best results. |
| Slow Cooking | Low (200-250°F) | 6-8 hours | Produces very tender, almost shredded pork. Not ideal if you want a slightly pink center. |
| Pan-Searing | Medium-High Heat | 10-15 minutes total | Good for a quick meal; requires careful monitoring to ensure even cooking. |
| Sous Vide | 140°F (60°C) | 2-4 hours | Provides precise temperature control and ensures even cooking; requires a sous vide immersion circulator and vacuum sealer. |
Common Mistakes to Avoid
- Overcooking: The most common mistake is overcooking the pork loin, resulting in a dry and tough piece of meat. Always use a meat thermometer to monitor the internal temperature.
- Not Resting: Skipping the resting period prevents the juices from redistributing, leading to a drier final product.
- Uneven Cooking: Ensure even heat circulation by using a roasting rack and avoiding overcrowding the pan.
- Insufficient Seasoning: Pork loin has a mild flavor, so don’t be afraid to season it generously.
- Confusing Loin with Tenderloin: These cuts require different cooking times and techniques. Double-check which cut you’re working with.
