Does it get much better than a summer cookout with a slightly sweet, tender, and moist smoked pork loin? Yup – I didn’t think so. This recipe uses a brine so that you don’t end up with a dry and boring pork loin. Never serve chewy pork again!

This Traeger smoked pork loin roast is a firm favorite in my BBQ playlist. It is brined overnight with herbs, giving it a flavorful and moist interior that works perfectly with the pork butt rub. The result is a super tender and juicy pork loin that’s made even tastier with my signature maple and apple glaze!

You can technically cook this in an oven, but I love smoked pork loin on the pellet grill. After all, who doesn’t love BBQ? The smoker does most of the work, and cleanup is super easy! The smoke completely infuses the pork, giving it a wonderful smokiness that you just can’t beat. Serve it with some parsley baby potatoes, parmesan broccoli, and butternut squash for the ultimate family dinner.

Now, who wants seconds?

🗒️ Ingredients for Perfect Smoked Pork

Here is everything you will need to make this Traeger smoked pork loin during your next cookout. For more detailed instructions and recipe notes, scroll down to the recipe card.

For the pork loin and glaze

  • Pork loin. Pork loins are usually sirloin, blade, or center cuts. It doesn’t matter which you pick, but make sure you choose a large and lean cut for this recipe. If you’re remotely unsure, a local butcher will be able to help.
  • Olive oil. A high-quality extra-virgin olive oil is best as it’s loaded with antioxidants and smokes well.
  • Pork seasoning rub. Your favorite seasoning rub is fine or use our pork butt rub. You can always spice it up with a couple of spices for more heat!
  • Apple juice. Gives the glaze a fruity and sweet punch. You can also use orange juice or pineapple juice.
  • Maple syrup. Maple syrup enhances the flavor of the pork while adding a light sweetness.
  • Dark brown sugar. As well as adding that signature dark color to the glaze, the molasses content will add depth and richness.
  • Dijon mustard. A touch of spice and a hit of acidity.
  • Soy sauce. Adds saltiness and extra savory flavor to the glaze that finishes it off beautifully.

For the pork brine

  • Water. Enough said.
  • Kosher salt. The large grains in kosher salt are perfect for brine as they’re flat and flaky. So, they dissolve incredibly well in hot water for a clear and well-seasoned brine.
  • Dark brown sugar. Counteracts the salty flavor of the brine while adding depth to the meat.
  • Black peppercorns. Whole peppercorns will infuse the loin with flavor without sticking to it! They also add a spicy tartness to the mixture.
  • Fresh rosemary. A couple of sprigs of rosemary add a bright and fresh flavor. Parsley and basil are also wonderful add-ins!
  • Dried bay leaves. For a savory background flavor that adds a layer of complexity to the brine.

👨‍🍳 How to Smoke Pork Loin

This is a quick overview of how to make this juicy smoked pork loin. For detailed instructions, scroll down to the printable recipe card.

Brine and Prepare the Pork Loin

  1. Bring water to a boil and add the salt and aromatics. Then cool the brine with water or ice. Trim excess fat from the pork and add it to the brine. Leave it overnight in the fridge.
  2. The next day, remove the pork loin and pat it dry while you prepare your smoker and glaze.

Smoke the Pork Loin

  1. Preheat your smoker to 225°F. Score the fat cap and coat the pork loin in olive oil.
  2. Sprinkle the dry rub over the pork and ensure all sides are coated well. Place the pork loin on the grill grates and close the lid.
  3. Prepare the glaze while the pork loin smokes. Combine all of the glaze ingredients, other than the butter, in a saucepan over medium heat and simmer until thickened. Remove from heat and add the butter and whisk until incorporated. Chill the glaze.
  4. Brush the loin with the glaze several times throughout the cook and wait until the internal temperature reaches a medium rare, around 140°F internal.
  5. Remove the smoked pork loin from the Traeger and let it rest before slicing.
  6. Serve and enjoy with an extra drizzle of glaze!

🤔 Substitutions and Variations Perfect Pork

  • Change out the liquid! You can switch out the apple juice for orange juice if you need to. Expect it to taste slightly more acidic in the glaze.
  • Sauce it up! It’s always fun to serve this smoked pork loin roast with a bunch of BBQ sauce as an addition to the glaze!
  • Switch it up. If you don’t have maple syrup on hand, honey works just as well for the glaze.
  • Rub it down! You can use our pork butt rub or any other pork rub in this recipe. Whatever your preference is, adjust the dry rub as needed. Try out this delicious pork dry rub that blends garlic, honey, and molasses.

😉 The Secret to Moist Pork Loin

  • Brine the pork overnight! It’ll have more time to soak up the delicious flavors from the aromatics. Plus, it’ll be way more moist and tender once it is smoked!
  • Cool the brine down quickly. Use a few ice cubes to bring the temperature down after making the brine. You don’t want to throw the pork loin in a hot brine.
  • Internal Temp: The USDA recommends cooking pork to an internal temperature of 145°F. I usually pull my smoked pork when it reaches about 140°F and then cover it and let it rest for 10 minutes.
  • Temp the meat! It’s a good idea to use an accurate thermometer to check your smoked pork loin. This should give you peace of mind while cooking.
  • Introduce moisture! To keep your smoked pork loin moist, you can use a water pan in the Traeger to keep the atmosphere in your Traeger moist.
  • Monitor the smoker’s temperature. Make sure there aren’t any fluctuations in your cooking temp and that there are no cold/hot spots inside the smoker. Move the pork loin around while it cooks, if needed.
  • Mind the fat cap: If there’s any fat left on your pork loin, smoke it fat-side up for added flavor and juiciness.

⏱️ Storage and Reheating

I recommend slicing the pork relatively thin and storing the leftovers in an airtight container in the fridge. It should stay tasty for up to 5 days.

If you’re reheating it, you can either pop it in the air fryer for a few minutes or place it back on the grill.

Otherwise, reheating it in the oven for approximately 20 minutes in a covered dish should work!

❓ Still Have Questions?

Do you flip pork loin when smoking?

Nope, there’s no need to flip your pork loin on the smoker. If you have a large smoker and the temperature is not even, you can flip or even rotate and move the pork loin throughout the cooking time. Use a thermometer to monitor the temperature of the Traeger smoker to make sure it is consistent and even.

Do you cover pork loin in foil when smoking?

I don’t recommend covering your pork loin with foil when it is on the smoker. The foil will create a barrier between the smoke and your meat. Also, you will be removing the pork from the Traeger once the internal temperature reaches 140°F to 145°F, so you won’t need to worry about using foil to get through the dreaded stall.

What is the best wood or pellet flavor to use when smoking pork?

Fruit woods like apple and cherry are great with pork. You can also use hickory, pecan, or a blend. This comes down to personal preference and how much smokiness you want.

How long to smoke pork loin at 225°F?

It will take about 2 hours to cook your pork loin at 225°F. It is best to monitor the temperature at the center of your pork loin roast while it is cooking on the smoker. Every smoker behaves differently, so cooking based on time is not very consistent or accurate. Instead, pull the pork loin from the Traeger pellet smoker once it reaches 140°F to 145°F.

🐖 Pork Loin vs Pork Tenderloin

What is Pork Loin

Pork loin is a long cut of meat that comes from the muscle that runs along the back of the pig from the midsection to the rear. It is a moving muscle, meaning that it contributes to the pig’s movements throughout its life. This means that pork loin can be tough, and it is especially prone to overcooking. Compared to tenderloin, it benefits from the added moisture that the brine gives it. Also, be sure to cook it to a medium rare to ensure that it isn’t tough and chewy. Smoking pork loin is always a good option because the low-and-slow method helps to give you a consistent and even cook throughout the large piece of meat.

Pork loin is much larger than tenderloin. They are generally 2-5 pounds. You can also get the pork loin from the butcher with the bone-in or boneless.

What is Pork Tenderloin

Pork tenderloin also comes from the back of the pig. It is a muscle that is up against the spine near its rear. The tenderloin muscle is not a movement muscle, so it is generally much more tender than a pork loin.

Pork tenderloin is much smaller and usually weighs between 1-2 pounds.

How do you keep pork loin from drying out on the smoker?

The best way to smoke pork loin is by keeping your temperature low and smoking slowly. It’s also key to keep basting your pork with the glaze throughout the smoking process. Putting your pork loin in a brine before smoking will also help to keep it moist and tender while it cooks. If you like, put a water tray in your smoker to keep the humidity high on the grill.

Smoked Pork Loin

This smoked pork loin is versatile. It is a staple on those summer BBQ cookouts and also at Thanksgiving dinner.
In order to get a perfectly moist slice of pork, it is essential to prepare the pork loin correctly. Give the cut of meat an overnight bath in a fragrant brine so that it can soak up some moisture and stay tender throughout the cook.
While the pork loin is smoking on the Traeger, brush it with the apple and maple syrup glaze. The glaze coats the pork loin and gives it a touch of sweetness and a wonderful brown exterior that carmelizes to perfection in the smoker.
Fire up your smoker and invite over your family and friends!
Course: Grilling
Cuisine: American
Prep: 15 minutes
Cook: 2 hours
Total: 2 hours 15 minutes
Servings: 8 servings


  • 1 pork loin, 4-5 pounds
  • 2 tablespoons olive oil
  • ¼ cup pork butt rub

Pork Loin Brine

  • 12 cups water
  • 1-¼ cups kosher salt
  • ¼ cup dark brown sugar
  • 1 teaspoon black peppercorns, crushed
  • 1 sprig fresh rosemary, chopped
  • 2 dried bay leaves

Pork Loin Glaze

  • 1 cup apple juice
  • ½ cup maple syrup
  • ½ cup dark brown sugar
  • 1 tablespoon dijon mustard
  • 1 tablespoon soy sauce
  • 2 tablespoons unsalted butter


Brine the Pork Loin

  • In a small pot, bring 2 cups of water to a boil and immediately turn off the burner. Add the salt and brown sugar to the water and let it dissolve. Add in the bay leaf, rosemary, and peppercorns, and allow them to steep for 5 minutes.
  • Transfer the brine to a pot or container large enough to hold the pork loin. Add the rest of the cold water. You can add a cup of ice to cool the brine down quickly.
  • Once the brine is cool, add the pork loin and transfer the container to the fridge. Let the pork brine for 12 to 24 hours.

Make the Pork Glaze

  • In a saucepan over medium heat, combine all of the ingredients except the butter and bring it to a simmer.
  • Simmer the glaze for about 15-20 minutes until it thickens. Remove the glaze from the heat and add the butter to incorporate it.
  • Chill the glaze in the fridge while the pork cooks.

Prepare the Pork Loin

  • Preheat the Traeger to 225°F.
  • Remove the pork loin from the brine and pat it dry.
  • Drizzle on the olive oil to coat the pork loin. Sprinkle the pork seasoning on the pork loin, coating all sides.
  • Place the pork loin on the grill grates and smoke at 225°F. Brush the glaze on the pork 2-3 times during the cook. Smoke the pork loin for 2 hours or until the internal temp reaches 140°F to 143°F and the glaze carmelizes.
  • Remove the pork loin from the smoker and let it rest for 10-20 minutes before slicing. Ensure that the pork reaches 145°F internally for a few minutes while it rests.
  • Serve the sliced pork loin with a drizzle of glaze over the top.


  • For best results, brine the pork loin overnight. The pork will be much more moist, and the flavors from the aromatics will better infuse into the meat.
  • When cooling the brine down after boiling, use some ice cubes to cool the brine down faster.
  • The USDA recommends cooking pork to an internal temperature of 145°F, but I prefer cooking my pork to a temp of about 140°F before pulling it from the smoker and letting it rest. The pork will be juicy and moist. Be sure to monitor the temp of the pork while it rests to ensure that it reaches 145°F for a few minutes.
