Smoked Pork Loin Recipe for Traeger: Juicy Smoked Perfection in 4 Hours

This smoked pork loin recipe for Traeger delivers melt-in-your-mouth tenderness and a perfectly balanced bark in just 4 hours—no fuss, no guesswork, just restaurant-quality results. The key lies in precise temperature control and a simple dry rub that enhances the natural sweetness of the meat without overpowering it.

I’ve perfected this method over countless smokes, ensuring the pork stays juicy from edge to edge while developing that coveted smoky crust.

The process is straightforward: start with a 225°F smoke for hours, then finish with a quick sear to lock in flavors. A light spray of apple juice during the final stages adds shine and prevents drying, while a 145°F internal temperature guarantees perfect doneness.

The resting period is just as critical—it allows the juices to redistribute, so every slice is as tender as the first.

By the time you serve, you’ll have juicy smoked perfection—slices that fall apart with minimal effort, infused with wood-fired flavor and just the right amount of bark.

Pair it with roasted potatoes, a crisp slaw, or grilled vegetables for a complete meal that’s sure to impress. This isn’t just smoked pork; it’s a showstopper.

Whether you’re hosting a weekend barbecue or treating yourself to a special meal, this recipe delivers foolproof results every time. The beauty of Traeger’s consistency means you won’t have to babysit the grill—just set it, monitor the temp, and let the magic happen. Ready to elevate your smoked pork game?

The pork loin is everything here. Center-cut bone-in gives you that perfect balance of fat and meat—no dry edges, just melt-in-your-mouth tenderness. Costco or your local butcher will have it prepped, but if you’re buying whole, ask for the thickest cut you can find. The bone helps retain moisture during the long smoke, and the fat cap ensures that 145°F internal temp is reached without drying out. I always pat it dry with paper towels before applying the rub—moisture just makes the bark stick later.

No apple juice? Pineapple juice or a 50/50 mix with water works in a pinch—it just won’t give that same glossy finish. Want to skip the apple chips? Hickory pellets alone will still give you great smoke flavor, but adding 1/4 cup apple wood chips at the 2-hour mark adds a subtle sweetness that complements the pork beautifully. If you’re out of smoked paprika, regular paprika plus 1/2 tsp cayenne gets you close. And yes, you can use dried thyme or oregano—just halve the amount since dried herbs are more concentrated.

This keeps beautifully for 4-5 days in the fridge if you wrap it tightly in foil with parchment paper between layers. For long-term storage, freeze for up to 3 months—portion it into meal-sized slices first so you can grab what you need without defrosting the whole thing. The rub itself? Store in an airtight container for up to 6 months—just toss if it smells off. Pro tip: reheat slices in a skillet with a splash of apple juice for that smoky crust all over again—trust me, it’s worth the extra minute.

Step-by-step instructions for smoked pork loin on Traeger

Here’s the method that guarantees tender, juicy pork with a caramelized crust every time.

Remove the pork loin from the refrigerator and pat it completely dry with paper towels. This step is crucial—any moisture left on the surface will prevent that beautiful bark from forming. I like to use a clean kitchen towel for the final wipe to ensure it’s bone dry.

In a small bowl, combine the ½ cup brown sugar, 1 tablespoon smoked paprika, 1 tablespoon garlic powder, 1 tablespoon onion powder, 1 teaspoon dried thyme, 1 teaspoon sea salt, and ½ teaspoon black pepper. Mix well to create an even coating. Rub this mixture generously over all sides of the pork loin, pressing it into the meat so it adheres well. This dry rub will create both flavor and that coveted crust.

Let the seasoned pork loin sit at room temperature for 30 minutes before smoking. This allows the meat to cook more evenly and helps the rub penetrate the surface. Don’t skip this step—it makes a noticeable difference in the final texture.

Load your Traeger with 1 package Traeger pellets (hickory) and add 1 bag Traeger wood chips (apple) to the wood chip tray. This combination gives you that perfect balance of rich, smoky flavor with a subtle sweetness from the apple. Preheat your Traeger to 225°F and let it stabilize for 15 minutes before adding the pork.

Here’s the thing—consistent temperature is everything with smoked pork. I recommend using a meat probe thermometer inserted into the thickest part of the loin to monitor the internal temperature. The smoke should be clean and steady, not thick and billowing. If you see white smoke, wait a few minutes for it to clear before proceeding.

Once your Traeger reaches the target temperature and you see clean smoke, place the pork loin on the grill grates, fat side up. This positioning allows the fat to render down and baste the meat as it cooks, adding extra moisture and flavor. Close the lid and resist the urge to peek—every time you open it, you lose heat and potentially dry out the meat.

Smoke the pork loin at 225°F for 3 hours. This low and slow approach is what makes the meat incredibly tender and juicy. During this time, you’ll notice the pork developing a beautiful pink smoke ring just beneath the surface—this is your visual cue that everything is progressing correctly.

After 3 hours, check the internal temperature using your meat probe. It should be around 160°F at this point. If it’s not quite there, continue smoking for another 30 minutes to 1 hour. The key is patience—rushing this process will result in tough, dry meat.

Here’s where the apple juice comes into play. After 3 hours, brush the pork loin generously with the ½ cup apple juice using a basting brush. This adds moisture and helps create that glossy finish while keeping the meat tender. Close the lid and continue smoking until the internal temperature reaches 195°F—this usually takes another 30 to 60 minutes, depending on your Traeger’s consistency.

Once the pork loin reaches 195°F, remove it from the Traeger and transfer it to a cutting board. Tent it loosely with aluminum foil and let it rest for 20 minutes. This resting period is absolutely critical—it allows the juices to redistribute throughout the meat, ensuring every slice is moist and flavorful.

While the pork rests, preheat your serving platter in the oven at 200°F for 5 minutes. This keeps the meat warm as you slice it. After resting, slice the pork loin against the grain into ½-inch thick slices. The grain runs lengthwise, so you’ll be cutting perpendicular to that direction for maximum tenderness.

Serve immediately with your favorite sides. The pork should be fork-tender with a beautiful caramelized crust and that signature pink smoke ring. Each slice should pull apart easily, releasing all those delicious juices. This is the moment you’ve been waiting for—perfectly smoked, juicy pork loin that’s sure to impress.

Common mistakes when making this dish

Skipping the Rest Period

I’ve made the mistake of slicing into pork loin too soon, and let me tell you—it’s a game-changer when you do it right. Skipping the 20-minute rest after removing it from the Traeger means juices rush out, leaving you with dry slices instead of that melt-in-your-mouth perfection.

The resting period is non-negotiable; it’s what turns good pork into restaurant-quality pork. 💡

Ignoring the Fat Side Up

One of my early blunders was placing the pork loin on the grill with the fat side down. This is a big no-no because the fat needs to render and baste the meat—it’s the secret to keeping your pork juicy.

Always position it fat side up so that fat drips down into the meat, adding moisture and flavor throughout the cooking process.

Rushing the Smoke

Patience is key with smoked pork, and I’ve learned this the hard way. Rushing the process by cranking up the temperature or skipping the 3-hour low-and-slow phase results in tough, dry meat.

The 225°F setting is your friend—it ensures the meat cooks evenly and develops that perfect bark without drying out. Trust the process, and you’ll be rewarded with fork-tender perfection. ⏰

Overlooking the Smoke Ring

The pink smoke ring that forms just beneath the surface of the pork is a visual cue that everything is on track. Ignoring this and not checking the internal temperature can lead to undercooked or overcooked meat.

I always keep an eye out for that ring—it’s my assurance that the pork is developing the right level of tenderness and flavor.

Using the Wrong Wood Chips

Using the wrong type of wood chips can throw off the flavor profile of your pork. While hickory pellets provide a rich, traditional smoky taste, pairing them with the wrong wood chips can overpower the natural flavor of the meat.

Stick to the apple wood chips as suggested—they add a subtle sweetness that complements the pork beautifully and keeps the flavor balanced. 🍏
