Smoked Pork Loin on a Pit Boss Pellet Grill

Learn step by step how to make a smoked pork loin, sometimes called a tenderloin, on a Pit Boss pellet grill and why this is such a great way to prepare this ultimate pork roast!

 

A full pork loin is a large cut of lean meat that is juicy and flavorful when cooked properly. This white meat can dry out when overcooked, so making sure you cook it just to the target internal temperature is important.

Pork tenderloin is a smaller section of the full pork loin but can be seasoned and cooked in much the same way, just for less time.

We'll show you how to prepare and smoke a pork loin so that stays moist and juicy!

Trim the Fat

You shouldn't have to trim too much fat or connective tissue if you bought a pork tenderloin to smoke on the Pit Boss.

The tenderloin is generally the 2 lb center section of the full 6-8 lb boneless pork loin that usually contains the best meat.

Depending on your crowd and your budget, you can either buy multiple tenderloins or a single loin to smoke in your Pit Boss.

Other the time it takes to cook, all our directions below will apply to either choice, but check out our Pit Boss Smoked Pork Tenderloin for more specific instructions.

If you bought a nicely trimmed pork tenderloin, great, no trimming necessary.

If however, you have a full pork loin with some fat and connective tissue, you'll need to do a little trimming before seasoning it and throwing it on the Pit Boss.

Use a good boning or filet knife like our favorite one from iMarku to first remove any excessive fat that is attached to your pork loin.

You do not need to completely remove the exterior fat like we did with our Pit Boss Smoked Beef Tenderloin.

Our Favorite Seasonings

Unlike our beef tenderloin, we are going to go for a more sugary rub like traditional pork butt and ribs might call for.

Pork pairs so well with sweeter rubs and traditional BBQ seasonings.

If you don't feel like making your own rub, our favorite off the shelf rubs for smoked pork loin are Famous Dave's Rib Rub and Blue's Hog Dry Rub Seasoning.

We also love Three Little Pigs, particularly Three Little Pigs Touch of Cherry, on pork.

It's got a fantastic traditional sweet (but not overly sweet) flavor profile with a little heat and garlic kick at the end.

We use it all the time on ribs, pork butt, and chicken.

If you want to use a quality rub without the sugar, we are big fans of Bad Byron's Butt Rub Seasoning on smoked pork loin because it is heavy on flavor, and has no sugar.

It also works great on hamburgers or chicken wings, or anytime you are reverse searing, like on steak.

We aren't going to reverse sear our smoked pork loin today, just let it cook low and slow on the Pit Boss.

But if you DO want to cook it at a higher temperature and not have to worry about burning your sugary rub, then go with something like Bad Byron's.

To add the BBQ rub to the pork loin, first oil the outside of the meat with Canola oil or olive oil. Then sprinkle generously with the BBQ rub(s).

We like to use disposable nitrile gloves when seasoning meat. We recommend having one gloved hand to touch the meat and press down the rub and the other hand with no glove to handle the bottles of rub.

Once the rub has been added to all sides of the meat, allow the rub to penetrate the meat for about 30 minutes. You can do this at room temperature or, ideally, covered in a refrigerator.

Because cold meat absorbs more smoke flavor, chilling the pork before smoking will maximize the smoke taste you get in the cooked pork.

Our Favorite Wood Pellets

You have a lot of options when it comes to choosing the right wood pellets to smoke your pork loin on a Pit Boss pellet grill.

Mesquite and hickory will give a very aggressive smoke flavor to the lean pork loin, usually a little too much, if used solely on their own rather than mixed with a milder fruitwood or blend.

Pecan, apple, beech, alder, and cherry pellets all give great results on pork when cooked on a Pit Boss.

However, our hands down can't go wrong favorite is straight up Pit Boss Applewood Pellets when smoking pork.

Especially leaner pork cuts like pork loin and pork tenderloin, you can't go wrong with that mild applewood smoke.

For the best results, store your unused pellets in a sealed room temperature container like this 20 lb pellet container rather than in the Pit Boss hopper outside.

Pellets do not last forever, but will definitely last a LOT longer if stored indoors in a quality airtight container.

Setting up the Pit Boss

We have previously covered how to season a Pit Boss, how to start a Pit Boss, as well as how to troubleshoot the smoke level of your pellet grill.

So if you need a more in-depth review on how to use your Pit Boss for the first time, check those articles out first!

Handling the Pork loin

One of our biggest tips when smoking a large piece of meat like a pork loin is to use cloth gloves underneath disposable nitrile gloves to transfer the meat to and from the grill and to flip it during cooking.

We have found it very difficult to use tongs or other BBQ tools to handle a piece of meat this size.

The cloth gloves protect your hands from the heat of the meat and grill grates, while the disposable gloves can be changed often as they get seasoning and raw meat and meat juices on them.

Smoking Temperature

After preheating, we recommend initially setting up the Pit Boss to cook on the Smoke Setting at 180°F.

We like doing this for two reasons:

1. The Pit Boss makes the most smoke on this setting and our meat absorbs the most smoke flavor when it is fresh and still cold on the grill. So it's the perfect way to start off a low and slow cook like this.
2. It will partially cook our pork loin without cooking it too fast, allowing it to absorb plenty of smoke flavor before we turn up the heat to finish it.

After about 30-40 minutes on the Smoke setting at 180°F, go ahead and turn up the heat on your Pit Boss to 250°F until it's finished.

You will probably want to flip it over after about 1 hour or so into the cook so that both the top and bottom cook evenly, since most of the heat from the Pit Boss comes from below.

 

Target Internal Temperature

You HAVE to use a good instant read meat thermometer to know where the internal temperature is of your smoked pork loin while it's cooking on the Pit Boss.

Ideally, you want a good leave in probe thermometer like the Thermopro, as well as an instant read thermometer to spot check different points of thickness along the pork roast.

While we have used and recommended ThermoPro for years, lately we have also become big fans of the MEATER leave in thermometer.

It is extremely accurate and has an incredible 165 foot bluetooth range and works right with your smartphone so you don't need to carry a separate controller around with you like many other remote thermometers require.

In fact, the thermometer itself is COMPLETELY WIRELESS, so no more awkward wires running out of the side of your smoker!

It's got a great free app that is constantly being updated and even has an algorithm to predict how much longer your type of meat will take to cook based on cooking temperature, target temperature, and current internal temperature.

It's like a GPS for your meat!

We are going to slowly bring the internal temperature up to about 140-145°F, then remove it from the Pit Boss and let it rest before slicing.

 

Cooking Time

A full size 6-8 lb pork loin will take roughly 1 and ½ hours in total to reach 145°F internal temperature when cooked at 180°F for the first 30 minutes and then turned up to 250°F for the remaining time.

A smaller 2 lb pork tenderloin may only take about an hour at most.

This is why it is so important to use a good instant read thermometer like we talked about above.

Then you will need to let the pork loin rest after smoking it before carving.

Unless you want those delicious juices running all over your cutting board instead of staying in the meat where you want them, you need to set aside time for the meat to rest!

 

Carving and Serving

You will then remove the smoked pork loin or tenderloin from the hot Pit Boss and let it rest.

Let the roast rest for 20-30 minutes before carving.

Use a good meat slicing knife and cut the smoked pork loin into nice thick slices based on how many guests you are serving.

We particularly like this meat slicing knife from Mairico.
