Smoked Pork Loin Recipe Pellet Grill: Juicy Wood-Fired Flavor in Hours

This pellet grill method delivers juicy pork loin with smoky depth and perfect tenderness every time.

With precise temperature control and wood-fired flavor, you’ll achieve restaurant-quality results in just a few hours.

Ingredients for Smoked Pork Loin Recipe Pellet Grill

A few quality ingredients transform pork loin into a smoky, tender masterpiece on the pellet grill.

Optimal quality requires a well-marbled pork loin—look for pale pink color with a thin fat cap. Professional kitchens use Costco or local butchers for consistent sizing. The loin should feel firm yet slightly springy to the touch. Avoid pre-brined cuts, as they’ll throw off your seasoning balance. Standard practice is to let the meat rest at room temperature for 30 minutes before applying the rub.

Substitutions are possible but impact final flavor. Pork shoulder works but requires longer cook times. Swap smoked paprika for regular if needed, though the smokiness will be less pronounced. Maple syrup at half the amount can replace brown sugar. No apple juice? Apple cider or even water works for spritzing, though the mild sweetness will be absent.

Store the raw pork loin in its original packaging in the coldest part of your refrigerator for up to 5 days. The dry rub can be made ahead and stored in an airtight container for 1 month. Once smoked, the pork keeps well-wrapped for 4 days or frozen for 3 months.

Step-by-Step Instructions for Smoked Pork Loin on Pellet Grill

Master the process for tender, wood-fired pork with this tested pellet grill method.

Step 1: Create the Flavorful Dry Rub

In a small bowl, combine the 2 tbsp Kosher Salt, 1 tbsp Black Pepper, 1 tbsp Garlic Powder, 1 tbsp Onion Powder, 1 tsp Smoked Paprika, 1 tsp Dried Thyme, and 1 tsp Dried Rosemary. I rub the dried herbs between my fingers as I add them to release their aromatic oils.

Add the 2 tbsp Brown Sugar and stir until fully incorporated. This blend creates a balanced crust that enhances the pork’s natural flavor without overpowering it. The sugar will caramelize during cooking, adding depth to the bark.

Step 2: Prepare and Season the Pork Loin

Pat the 3 lb Pork Loin completely dry with paper towels. This step is crucial—moisture prevents the rub from adhering properly and inhibits bark formation. Trim any remaining excess fat, leaving a thin layer for flavor and moisture.

Drizzle the 2 tbsp Olive Oil over the pork loin and rub it evenly across all surfaces. This helps the dry rub stick and promotes even browning. Apply the rub mixture aggressively, pressing it into the meat so it forms a visible crust. Let the seasoned pork sit at room temperature for 30-45 minutes while you prepare the grill.

Step 3: Set Up the Pellet Grill and Begin Smoking

Fill your pellet grill’s hopper with the 2 cups Pecan Wood Pellets. Preheat the grill to 225°F using the smoke setting if available. Pecan wood provides a mild, slightly sweet smoke that complements pork beautifully without overwhelming it.

Once the grill reaches temperature and you see clean, thin blue smoke, place the pork loin directly on the grill grates, fat side up. Insert a meat probe into the thickest part of the loin, avoiding the fat cap. Close the lid and maintain 225°F throughout the cook.

Step 4: Smoke to Perfection with Occasional Spritzing

Smoke the pork loin undisturbed for 2 hours. After this initial period, begin spritzing with the 0.5 cup Apple Juice every 45-60 minutes. This adds moisture and a subtle sweetness that enhances the bark. Use a spray bottle for even distribution.

Continue smoking until the internal temperature reaches 145°F. This typically takes 3-4 hours total, depending on your grill’s consistency and the pork’s initial temperature. The loin should develop a deep mahogany bark while remaining juicy inside.

For an extra flavor boost, mix the 0.25 cup Apple Cider Vinegar with an equal amount of water and spritz during the last hour of cooking. The vinegar’s acidity balances the richness of the pork.

Step 5: Rest and Slice for Maximum Juiciness

When the pork reaches 145°F, remove it from the grill and transfer to a cutting board. Tent loosely with foil and let it rest for 15-20 minutes. This resting period allows the juices to redistribute throughout the meat, ensuring every slice is moist and flavorful.

Slice the pork loin against the grain into ½-inch thick pieces. The grain runs lengthwise through the loin, so you’ll be cutting perpendicular to this direction. Serve immediately while still warm—the meat should be tender with a slight pink hue in the center and a beautifully caramelized crust on the outside.

Pro Cooking Tips for Perfect Results

Temperature Control

Pellet grills excel at maintaining steady heat, but I always verify with a dual-probe thermometer. The grill’s built-in probe can be off by 10-15°F. Aim for a consistent 225°F throughout the smoke for the best texture. 🌡️

Bark Formation

The dry rub creates a flavorful crust, but don’t over-spritz. Too much liquid can wash away the seasoning. I use apple juice every 45-60 minutes just enough to keep the surface moist without creating steam.

Fat Side Up

Always position the pork loin with the fat cap facing up. As it renders, the fat bastes the meat naturally. This simple step prevents dryness and enhances flavor penetration. I also rotate the loin 180° halfway through for even cooking.

Probe Placement

Insert your meat probe into the thickest part, avoiding the fat cap and bone if present. For a 3 lb loin, the center is usually the last to reach 145°F. I check multiple spots to ensure accuracy.

Resting Time

Resist the urge to slice immediately. Resting for 15-20 minutes allows juices to redistribute. Tent loosely with foil to keep it warm. The internal temperature will rise 5-10°F during this time, so pull it at 145°F for perfect doneness.

Pellet Choice

Pecan wood offers a mild, sweet smoke, but hickory provides a stronger flavor. For a balanced profile, I mix 50/50 pecan and hickory pellets. Avoid mesquite—it can overpower the pork’s natural taste. 🔥
