Smoked Pork Loin Recipe Traeger: Pellet-Grilled Juiciness With Bark Perfection

Mastering pork loin on a Traeger means achieving perfect juiciness with a dark, flavorful bark that cracks with every slice. This method leverages the pellet grill’s consistent heat to transform a simple cut into a centerpiece worthy of any table.

The secret lies in a dry brine and a two-stage smoke process. First, a generous rub creates the foundation for that coveted bark. Then, low-and-slow smoking with fruitwood pellets infuses deep, smoky notes without overpowering the pork’s natural flavor.

After hours on the grill, you’re left with meat that pulls apart effortlessly, its exterior glistening with a mahogany crust. The interior stays moist and tender, proving that patience and technique yield results you can taste.

Serve sliced thick, with the bark prominently displayed. This is how you elevate a classic cut to something unforgettable.

Ingredients for Smoked Pork Loin Recipe Traeger

Pantry spices plus a quality pork loin. That’s all it takes for bark perfection on your Traeger.

The pork loin is everything here. Look for boneless cuts with even marbling—this ensures juiciness after hours on the smoker. Costco and Sam’s Club have great pre-trimmed options, but your local butcher can custom-cut to your preferred thickness. For the dry brine, Diamond Crystal kosher salt is the gold standard (its larger crystals distribute better on the meat’s surface).

No smoked paprika? Regular paprika plus a pinch of liquid smoke works in a pinch. Swap the brown sugar for maple syrup or honey if you prefer a stickier bark (just brush it on during the last hour). The apple cider vinegar can be white vinegar or lemon juice—any acid helps tenderize. If you’re out of mustard powder, Dijon mustard in the wet binder works too.

The dry brine can sit on the pork overnight (or just 4 hours if you’re short on time). Store the seasoned meat uncovered in the fridge to dry the surface—this is key for bark formation. Leftover smoked pork keeps 4-5 days in the fridge or freezes beautifully for 3 months.

Step-by-Step Instructions for Smoked Pork Loin

This method delivers that ideal balance of tender meat and crispy bark every time.

Step 1: Prepare and Season the Pork Loin

Pat the 3 lb Pork Loin dry with paper towels—moisture is the enemy of good bark formation. Trim any remaining excess fat, leaving just a thin layer for flavor and protection during the long smoke.

In a bowl, combine the 2 tbsp Kosher Salt, 1 tbsp Coarse Black Pepper, 1 tbsp Garlic Powder, 1 tbsp Onion Powder, 2 tsp Smoked Paprika, 1 tsp Dried Thyme, 0.25 cup Brown Sugar, and 1 tsp Mustard Powder. Stir in the 2 tbsp Apple Cider Vinegar to create a paste-like consistency.

Rub the 2 tbsp Yellow Mustard all over the pork loin—this acts as a binder for the dry rub. Then apply the spice mixture generously, pressing it into the meat so it adheres well. Drizzle with 2 tbsp Olive Oil and rub again to ensure even coverage.

Step 2: Set Up Your Traeger for Low and Slow Smoking

Fill your Traeger’s hopper with 20 lb Fruitwood Pellets—apple or cherry wood works beautifully here. Preheat the smoker to 225°F with the lid closed for at least 15 minutes to stabilize the temperature.

Once preheated, place the seasoned pork loin directly on the grill grates, fat-side up. The fat will render down as it smokes, basting the meat and enhancing the bark. Insert a meat probe into the thickest part of the loin, avoiding the fat cap and bone if present.

Step 3: Smoke Until Internal Temperature Reaches the Stall

Smoke the pork loin undisturbed for 3-4 hours, maintaining a steady 225°F. You’ll know the stall is approaching when the internal temperature hits about 150-160°F and seems to stop rising.

Don’t be tempted to increase the heat during this phase. The stall is a natural part of the process as moisture evaporates from the surface. This is when that beautiful bark begins to form, so patience is key. Check the wood pellets occasionally to ensure you have enough for the entire cook.

Step 4: Wrap and Power Through the Stall

When the internal temperature reaches 165°F, remove the pork loin from the smoker and wrap it tightly in pink butcher paper. This “Texas crutch” method helps push through the stall while preserving the bark you’ve worked so hard to develop.

Return the wrapped pork to the smoker and continue cooking until the internal temperature reaches 200-203°F. This usually takes another 1-2 hours, but trust the probe over the clock. The meat should feel tender when probed, with the probe sliding in like butter.

Step 5: Rest and Slice for Maximum Juiciness

Remove the pork loin from the smoker and let it rest, still wrapped, for at least 30 minutes (up to 1 hour for even better results). This resting period allows the juices to redistribute throughout the meat.

Unwrap the pork and slice against the grain into ½-inch thick portions. Each slice should reveal a beautiful smoke ring just beneath the surface and a dark, flavorful bark. Serve immediately while still warm—the meat should be tender, juicy, and packed with smoky flavor.

Health Benefits of This Dish

Lean Protein Power

Pork loin is a lean cut that packs about 24 grams of protein per 3-ounce serving, supporting muscle growth and repair. Unlike fattier cuts, it delivers this protein with only 4 grams of saturated fat per serving, making it heart-healthy. I love how it keeps me full without feeling heavy. 💪
