The Basics: Prepping Your Pork Loin

Before diving into the specifics of cooking time, its essential to prepare your pork loin correctly. Prepping includes trimming excess fat, marinating, and seasoning. This foundational step sets the stage for a flavorful result. Preheat your gas grill to about 350F (175C) for direct grilling of pork loin.

Ideal Marinade and Seasoning

Marination is not an obligatory step, but it enhances the flavor and tenderness of the pork loin. A simple mixture of olive oil, garlic, rosemary, salt, and pepper usually works wonders. For more intense flavors, you might consider marinating the loin overnight.

Setting the Grill: Indirect vs. Direct Heat

One of the golden rules of grilling is understanding the heat zones. Pork loin is best cooked over indirect heat, which allows the meat to cook evenly without burning the exterior. Set one side of your gas grill to high heat and the other to medium-low.

Indirect Cooking on a Gas Grill

For indirect cooking, place the pork loin on the medium-low side and close the lid. This will create an oven-like environment within the grill, ensuring even cooking.

Timing and Internal Temperature

The golden question is, How long to cook a pork loin on a gas grill? The answer largely depends on the size of your pork loin and the consistency of your grills temperature. Typically, you should cook a pork loin of around 3-4 pounds for approximately 1 to 1.5 hours. However, it's not just about time; the internal temperature is a more reliable measure.

Checking for Doneness

Use a meat thermometer to check the internal temperature. The USDA recommends an internal temperature of 145F (63C) followed by a resting time of at least 3 minutes. This ensures the meat is cooked through yet remains juicy.

Resting the Meat

Once your pork loin reaches the desired internal temperature, its vital to let it rest. This allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful outcome. Tent the pork loin with aluminum foil and let it rest for 10-15 minutes before slicing.

Additional Tips and Tricks

Maintaining a consistent temperature is key to perfecting your pork loin. Avoid opening the grill lid frequently as it causes temperature fluctuations. Also, consider using a water pan in the grill to maintain moisture.
