Grilling Pork Tenderloin- Tips

Pork tenderloin is fantastic for grilling. With the right amount of seasoning and time, you’ll get a juicy, tender slab of meat that fully embraces the smokiness of grill cooking. If you don’t know for how long you should roast your pork tenderloins, don’t panic. But before you find out, confirm if you’re also aware of these vital grilling steps;

Preparing the Tenderloin

When you examine your pork tenderloin, you’ll notice a line of connective tissues on the meat. These tissues are called silver skin and don’t cook after grilling. So before anything, the first step is to cut out these tissues with a sharp knife.

Once that’s done, combine your favorite grilling spices to make a dry rub. Then, pat the pork tenderloin dry with paper towels and incorporate the dry rub onto the meat. Once you’ve fully seasoned the meat, you can proceed to prepare your grill. You can keep the seasoned pork tenderloin for an hour before grilling. You can also lock it in a plastic bag and toss it in the fridge overnight if you have time.

Preparing the Grill

The key to making great pork tenderloins on the grill is to cook them over two zones of heat. This ‘zone cooking’ technique involves creating two different heat zones on your grill surface, one hotter than the other. The low heat area helps cook the pork tenderloin at a steady, indirect heat, so the insides come to doneness. In contrast, the scalding side gives it a crust and char by direct heat. The zone grilling technique can be done on both the gas and charcoal grills.

On a gas grill, set the burner of one side to the highest or medium-high temperature, while the other side is set at the lowest temperature. The low-heat zone can also be unlit, and the indirect heat from the high heat zone will serve as its only heat source.

If you’re using a charcoal grill, pile up most of the hot coals to one side to make a direct heat zone. Leave very few hot coals on the other side; these form the area of indirect heat.

Pork Tenderloin Cooking Time

Pork tenderloin cooks quickly, and when done, you’ll get a pinkish inside, with a crispy outside. But to make sure you’re doing it right, you should cook your pork tenderloins for about 15 to 20 minutes on the grill. The meat is entirely done once the internal temperature reads between 140 to 145°F at the thickest part. Also, note that the cooking time rests on the size and density of the pork tenderloin.

Easy Grilled Pork Tenderloin (4 servings)

Save Recipe


  • One pork tenderloin, 1 pound
  • ½ cup dark brown sugar, lightly packed
  • One teaspoon smoked paprika
  • One teaspoon salt, kosher
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder


  1. Pat the pork tenderloins with paper towels to dry and trim off the silver skin. Combine the spices, sugar, and salt, and liberally rub the mixture all over the meat.  Leave to sit for an hour.
  2. Light up a gas grill and turn the burner at one side to medium-high. Reduce the burner at the other side to low. These settings will create your two-zone cooking area.
  3. Place the pork tenderloin over the high-heat zone (direct heat) and cover. Cook for 5 to7 minutes, flip and cook the other side for another 5 to 7 minutes.
  4. Move the pork tenderloin to the low-heat zone (indirect heat), and cover to cook for another 3 to 4 minutes. Check the internal temperature for doneness and set it down when the thermometer reads 140 to 145°F.
  5. Tent the pork tenderloin in aluminum and leave it to rest for 10 minutes, so the juices redistribute. Slice into thin pieces in a crosswise manner to serve.
