Since pork tenderloin has little fat, it can become tough very quickly when overcooked – I’m providing my best tips and tricks to keep pork tenderloin moist below:

This step is completely optional (and not recommended if you are more comfortable grilling) – but for cooks just learning to grill, you can lessen your grilling time by pre-searing your pork tenderloin in a pan inside, before wrapping it in foil and placing on the grill to cook to 145 degrees.

Searing your pork before grilling it not only helps to lock in the pork’s juices – it tastes great and gives you a perfect crunchy texture, even though you can continue to cook in a foil pouch on the grill.

The foil pouch will help to keep the pork’s tenderness, so it is a bitt more foolproof when starting out grilling – but you will miss out on the smoky grilled flavor a bit since you won’t have more char like my photos.

But if you’re starting out grilling, or don’t know if you will have enough propane or charcoal to last – or you’ve just had weird luck grilling pork tenderloin on the grill and want an easier hack, this tip works wonders!

Pre-seasoned pork tenderloins from your grocer are often dry-brined with salt beforehand, so it doesn’t need additional marinating or brining.

While this cuts WAY down on your cook-time, know that pre-seasoned/brined pork tenderloins tend to be a bit smaller than untreated pork tenderloin, and can sometimes be packaged with preservatives that might not work with restrictive diets or food allergies.

Double check the label to check on the pork tenderloin size and any marinade ingredients.

It can be tricky to figure out how much grilled pork tenderloin to serve per person – but I plan on 1/2 pound (8 ounces) of meat per person.

If you have eaters with big appetites, or if you want to have leftovers, plan on 3/4 pounds of pork (12 ounces) per person.

How To Grill Pork Tenderloin

These tips will help you get juicy flavorful pork tenderloin on the grill, every time.

You can use this recipe with charcoal, wood chips, or a propane grill – I prefer this recipe over charcoal personally, but any of the above will work just great!

Marinating or brining pork tenderloin before cooking will always help to soften the pork tenderloin and keep it from drying out.

I love using a bottle of simple Italian Dressing or a cup of olive oil with some lemon juice, salt, and pepper for an easy overnight pork tenderloin marinade.

Pork tenderloin dries out very quickly when overcooked – and grilling can be really easy to overshoot your temperature after you set down the lid.

Make sure you watch your pork and pull it from the grill at 140 degrees, and then tent in foil.

Tenting in foil will help the tenderloin carryover cook to the FDA suggested cooked temperature of 140 degrees, without over-cooking and drying out your grilled pork tenderloin.

I often pull my pork tenderloin at 140-145 degrees and tent it with foil to continue carryover cooking as it rests for about 10 minutes before serving.
