For the best results, start by cooking the meat over high temperature and then move it to a lower temperature over indirect heat.
I have been using this technique for more than a decade It’s one of my favorite ways to grill pork because it turns out a perfect pork tenderloin every time!
What is pork tenderloin?
Pork tenderloin and pork loin are two cuts of meat that often get confused.
The full pork loin is cut from the side of a hog without the belly or fat back. From the pork loin, butchers cut the tenderloin, riblets, back ribs, country-style ribs, the center cut loin and pork chops.
The pork tenderloin is a thinner and smaller cut of pork removed from the full pork loin. According to the North American Meat Institute, the tail end of the meat should be at least one inch thick and it should be “practically free of fat.”
It’s a lean cut of meat, but when cooked properly, it contains a lot of flavor and melts in your mouth.
- Pork Tenderloin: Be sure to grab pork tenderloin, not pork loin. It comes in a vacuum-sealed package. This recipe calls for two pork tenderloins because usually, two come in a package together. You can cut the recipe in half to just cook one.
- Mayonnaise: This acts as the binder and helps form a beautiful crust on the pork. Feel free to use original mayo, light mayo or even mayo made with olive oil.
- Pork Rub: My award-winning pork rub was made just for pork dishes like this. It has salt, pepper, garlic, chiles and sugar.
- BBQ Sauce: You can use any type of barbecue sauce. Try a homemade sauce like my Carolina Mustard BBQ Sauce or pick up a bottle from the grocery store.
Substitutions: If you don’t have my Pork Rub yet, you can mix up some kosher salt, black pepper, garlic powder, smoked paprika and brown sugar to make a quick dry rub.

Prepare your grill
For this grilled pork tenderloin recipe, start by heating your grill to high heat (400F degrees) with both a direct heat zone and an indirect heat zone.
- Charcoal Grill: Add lit Cowboy Charcoal to your grill. Push them to one side, so you have a direct and indirect heat zone. Adjust the vents until the grill temperature reaches 400F degres.
- Gas Grill: Turn one burner to high or medium-high heat. Adjust the dial as needed until the grill temperature reaches 400F degrees. You’ll start the cook over the burners that are on and finish it on the grill grate over the burner that is off. If you want to add smoke, use Cowboy Wood Chips in a foil pouch.
- Pellet Grill: Set your grill temperature to 400F degrees. For the last part of the cook, reduce the temperature to 350F degrees.
- Ninja Grill: Set the function to grill, the temperature to 400F degrees and the time to 25 minutes. For the last stage, reduce the grill temperature to 350F degrees.
How to grill pork tenderloin in under 30 minutes
- STEP ONE: Remove the tenderloin(s) from the packaging. Place them on a cutting board and pat them dry with a paper towel.
- STEP TWO: Using a sharp knife, like a boning knife or filet knife with a point, remove any noticeable silver skin from the pork tenderloins. Use the point to work your knife under the white layer. Then, slide your knife to remove it from the meat.
- STEP THREE: In a small bowl, combine the mayonnaise with the pork rub. Stir until smooth.
- STEP FOUR: Using your hands or the back of a spoon, rub the mayonnaise mixture all over the pork tenderloins. Grill them right away or place them in a plastic resealable bag and marinate the pork tenderloin for 30 minutes up to several hours.
PRO TIP: If you let the rubbed pork tenderloins marinate in a bag, make sure they are still fully coated with the mayonnaise blend when you remove them from the bag. You want that coating in order to form a great crust.
- STEP FIVE: Place the pork tenderloins on the heated grill over direct heat. Close the lid and cook for 7 minutes. Flip. Cook for 7 more minutes.
- STEP SIX: Brush your favorite BBQ sauce all over the tenderloins and move them to the indirect heat zone on your grill. Cook them for another 5-7 minutes.
PRO TIP: If you’re using a pellet grill or Ninja grill, reduce the grill temperature to 350F degrees.
- STEP SEVEN: Use a digital instant-read thermometer to measure the internal temperature of the grilled pork tenderloin. Once it reaches 145F degrees, they’re ready. Remove them from the grill.
PRO TIP: You don’t want the internal temperature of the pork to get much higher than 145F degrees, or it will start to dry out. To get the best reading, insert your meat thermometer into the center of the pork tenderloin from one of the ends.
