Tips and recipe for charcoal-grilled garlic pork tenderloin

By the Editorial Team · Wednesday, July 8, 2026

Charcoal grilling with hardwood charcoal creates distinct smoky flavors and requires precise temperature control and technique, such as using a chimney starter and managing heat zones for even cooking. Mastering this method with pork tenderloin marinated in a flavorful blend and cooked over direct and indirect heat results in a juicy, well-seasoned dish suitable for both charcoal and gas grills.

Charcoal grilling offers a distinct flavor profile that appeals to many cooking enthusiasts, combining the aroma of smoke with the texture of caramelized edges. Achieving consistent results over live fire requires practice and attention to technique, particularly when using hardwood charcoal as a fuel source.

Hardwood charcoal, produced by burning wood in a low-oxygen environment, differs from petroleum-based briquettes by burning hotter and faster, which can enhance the taste of grilled food. It is recommended to avoid lighter fluid and instead use a chimney starter, igniting paper beneath the charcoal to achieve evenly heated coals covered with white ash. Once ready, the hot coals are spread evenly on one side of the grill, creating a zone for direct cooking and a cooler area for finishing or managing flare-ups.

Maintaining the correct grill temperature involves adjusting air vents to control airflow, and using an oven thermometer can help ensure consistent heat. After placing the cooking grate on the grill and allowing it to heat for several minutes, food can be cooked directly over the hot coals. To prevent flare-ups and uneven cooking, it is advisable to turn food using a spatula rather than tongs, and to move items to the cooler side of the grill as needed.

Pork tenderloin is an ideal cut for developing charcoal grilling skills due to its lean texture and quick cooking time. A marinade incorporating garlic, shallot, soy sauce, fresh lime juice and rind, ginger, honey, gochujang (Korean red chili paste), and curry powder can infuse the meat with a balance of spicy, tangy, and sweet flavors. Marinating the pork for at least 30 minutes enhances its taste and tenderness.

During cooking, the pork tenderloin is first seared over direct heat until it develops a golden crust, then moved to the cooler portion of the grill to finish cooking slowly. An instant-read thermometer should be used to monitor internal temperature, aiming for 135 degrees Fahrenheit to ensure juiciness and food safety. After cooking, the meat is rested for 10 minutes before slicing.

The reserved marinade is boiled separately for a few minutes to eliminate any bacteria and then used as a sauce to accompany the pork. The dish can be served with sides such as potatoes and steamed greens, garnished with fresh cilantro. This combination pairs well with refreshing beverages like limeade or chilled beer, offering a complete meal ideal for warm-weather grilling.

For those using gas grills, a similar approach applies: heat the grill to medium, use a cooler zone by turning off center burners, and cook the pork initially over direct heat before transferring it to a lower temperature section to finish. This method helps replicate the control and flavors achieved with charcoal grills.
