Smoked Pork Loin Recipe Pellet Grill: Juicy Wood-Fired Flavor Without the Fuss

This pellet grill method delivers juicy, wood-fired pork loin with minimal effort and maximum flavor.

By maintaining precise temperature control and using a simple dry rub, you’ll achieve tender, smoky results every time.

Ingredients for Smoked Pork Loin Recipe Pellet Grill

Pantry spices and a quality pork loin create this wood-fired masterpiece with ease.

The pork loin is the foundation—look for a center-cut piece with even marbling at your butcher or Costco. Avoid pre-brined or enhanced cuts, as they affect the dry rub absorption. A 3-4 lb roast gives you perfect leftovers. The dry rub spices should be fresh (Penzeys is excellent for potency), and always grind your black pepper fresh for the most vibrant flavor.

No smoked paprika? Regular paprika plus a dash of liquid smoke gets you close. Out of brown sugar? Maple syrup brushed on before smoking works in a pinch. The mustard binder can be swapped for Dijon or even mayonnaise—just ensure full coverage. For the wood pellets, hickory delivers strong smoke, while apple or cherry adds sweetness.

Store the pork loin in the fridge for up to 3 days before cooking, or freeze for 6-12 months. The dry rub keeps indefinitely in an airtight container. Leftover smoked pork makes incredible sandwiches and stays fresh for 4-5 days refrigerated.

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

Master these techniques to achieve tender, wood-fired pork loin with optimal moisture and bark.

Step 1: Prepare the Pork Loin with Dry Rub

Pat the 3 lb Pork Loin completely dry with paper towels to ensure the rub adheres properly. I always trim any remaining excess fat at this stage to prevent uneven cooking. The surface should feel slightly tacky but not wet.

In a small bowl, combine the 2 tbsp Kosher Salt, 1 tbsp Coarse Black Pepper, 1 tbsp Garlic Powder, 1 tbsp Onion Powder, 1 tbsp Smoked Paprika, 1 tsp Dried Thyme, and 2 tbsp Brown Sugar. The brown sugar will caramelize during smoking, creating a beautiful crust.

Brush the 0.25 cup Yellow Mustard evenly over all surfaces of the pork loin. This acts as a binder for the rub. Immediately coat the pork with the dry rub mixture, pressing firmly to create an even layer. The mustard will absorb into the meat, leaving only the seasoning visible.

Step 2: Preheat and Set Up the Pellet Grill

Fill your pellet grill hopper with the 2 cups Wood Pellets. I recommend hickory for a robust flavor or applewood for a sweeter profile. Both complement the pork loin beautifully without overpowering it.

Set the grill to 225°F and allow it to preheat for 10-15 minutes with the lid closed. This ensures consistent temperature throughout the cooking chamber. The grill is ready when it maintains 225°F steadily and you see a light, clean smoke coming from the chimney.

Place a disposable aluminum pan filled with water on the grill grates to help maintain moisture during the long cook. Position it to the side of where the pork loin will sit, not directly underneath.

Step 3: Smoke the Pork Loin to Internal Temperature

Place the seasoned pork loin directly on the grill grates, fat side up. Close the lid and maintain the temperature at 225°F throughout the cook. Resist the urge to open the lid frequently—this causes temperature fluctuations and extends the cooking time.

After the first 2 hours, begin spritzing the pork loin every 45-60 minutes with a mixture of 1 tbsp Apple Cider Vinegar and 2 tbsp water. This keeps the surface moist and helps build the bark. The spritz will sizzle as it hits the hot meat—this is normal.

Continue smoking until the internal temperature reaches 145°F in the thickest part of the loin, typically 3-4 hours for a 3 lb piece. Use a reliable meat thermometer to check—don’t rely on time alone. The pork is done when it feels slightly firm but still yields to gentle pressure.

Step 4: Rest and Slice for Maximum Juiciness

Remove the pork loin from the grill when it reaches 145°F internal temperature. Transfer it to a cutting board and tent loosely with aluminum foil. Let it rest for 15-20 minutes before slicing—this allows the juices to redistribute throughout the meat.

The internal temperature will rise 5-10°F during resting due to carryover cooking. This is why we pull it at 145°F rather than the USDA’s safe minimum of 145°F—it ensures perfect doneness without overcooking.

Slice the pork loin against the grain into ½-inch thick medallions. Each slice should display a beautiful smoke ring just beneath the surface and a juicy, slightly pink center. The bark should be dark mahogany and slightly sticky from the caramelized rub.

Make-Ahead Tips for This Dish

Prep the Night Before

Mix your dry rub and apply it to the pork loin up to 12 hours ahead. I often prep mine the evening before, wrap it in plastic, and let it dry-brine in the fridge overnight. The salt penetrates deep, ensuring seasoning throughout. 💡

Grill Setup Shortcut

Fill your pellet hopper with wood pellets the night before cooking. This saves 10 minutes on cook day. I keep a sealed 5-gallon bucket of hickory pellets in my garage for easy access.

Cold Start Method

Place your seasoned pork loin on the grill while it’s still cold. Set the temperature to 225°F and let it preheat with the meat inside. This adds about 30 minutes to your cook time but creates a more pronounced smoke ring.

Partial Cook Strategy

Smoke the pork loin for 2 hours, then wrap it in foil and refrigerate overnight. The next day, finish cooking at 225°F until it reaches 145°F internal temperature. This works great for weekend meals.

Resting and Holding

Once done, wrap the pork loin in foil and a towel, then place it in a cooler. It’ll stay hot for 4-6 hours—perfect for timing with other dishes. I use this trick for holiday meals when oven space is limited. ⏰

Reheating Leftovers

Slice leftover pork loin and place it in a baking dish with ¼ cup apple juice. Cover with foil and reheat at 325°F for 15-20 minutes. This keeps the meat moist and delicious for sandwiches or salads.
