How Long Does it Take to Cook a Pork Loin Roast: Tips and Tricks

Understanding the cooking process of a pork loin roast can significantly enhance your culinary experience. Whether you're smoking, roasting, or slow-cooking, this guide aims to provide you with the necessary information to ensure your pork is perfectly cooked every time.

Core Temperature for Proper Cooking

Properly cooking pork, particularly a loin roast, ensures food safety and the juiciest results. The U.S. Department of Agriculture (USDA) recommends an internal cooking temperature of 145°F (63°C) for whole cuts of pork, including roasts, to ensure food safety and prevent foodborne illnesses. However, for a tender and moist loin, it's crucial not to exceed an internal temperature of 140°F (60°C).

Smoking a Pork Loin Roast

Smoking is one of the favorite methods for preparing a pork loin roast. It can take around 2-2.5 hours to achieve the desired result, with a smoker set to approximately 225°F (107°C). This slower cooking process helps in retaining the meat's natural juices, making it incredibly tender and full of flavor.

The key to a perfectly smoked pork loin roast is to monitor the internal temperature. Using an internal read thermometer like the iChef BT-600 paired with its app on your smartphone can help you set precise cooking temperatures and notifications. For example, you can set the app to alert you when the internal temperature reaches 145°F to ensure the meat is fully cooked, or when it reaches 140°F for optimal tenderness.

Roasting a Pork Loin Roast

For a roasted pork loin, cooking time varies according to the weight of the roast. Here is a general guideline:

Small loin roast: 2 to 5 pounds - 20-30 minutes per pound Crown roast: 4 to 6 pounds - 20-30 minutes per pound Leg of fresh ham, whole, bone-in: 12 to 16 pounds - 22-26 minutes per pound Leg of fresh ham, half, bone-in: 5 to 8 pounds - 35-40 minutes per pound Boston butt: 3 to 6 pounds - 45 minutes per pound Tenderloin roast: 1 pound - 20 to 30 minutes total

Preheat your oven to 350°F (177°C). Place the pork loin roast in a shallow pan, uncovered, and cook until the internal temperature reaches 145°F (63°C) for medium or 170°F (77°C) for well-done. Let the roast rest for 15 minutes before serving to allow the juices to redistribute.

Slow Cooking a Pork Loin Roast

For those who prefer a slower cooking method, slow cooking a pork loin roast turns out to be a delightful approach. Recently, we cooked two pounds of pork loin in a slow cooker on low for 10 hours, resulting in a heavenly dish seasoned with BBQ sauce, cumin, and other spices. Pulling the pork apart and keeping it on a warm setting makes it perfect for serving.

The best part about using a slow cooker is the convenience. The meat is always moist and tender, and there’s no need to babysit it. If you're cooking for a party or a gathering, this method ensures you can relax while the pork reaches the ideal temperature.
