Pellet Grill Pork Butt Recipe: Smoke-Infused Fall-Off-The-Bone Tenderness

There’s nothing quite like the aroma of pork butt slow-smoked to fall-off-the-bone perfection on a pellet grill. This method delivers consistent results with minimal effort, letting the wood pellets do the work.

I’ve refined this technique over years of competition cooking and backyard gatherings. The key is patience—low heat and steady smoke transform tough cuts into tender, flavorful masterpieces.

Ingredients for Pellet Grill Pork Butt

Pork butt plus bold rub ingredients transform into that signature smoky, fall-apart texture everyone craves.

The pork butt quality is non-negotiable. Bone-in cuts with generous marbling yield the most tender results. Source from Costco for consistent quality or ask your butcher for a well-trimmed piece. Look for 8-10 lb whole butts (this recipe uses half) with a good fat cap—this renders down during the long cook. USDA Choice grade offers the perfect balance of flavor and value for smoking.

No yellow mustard? Dijon works in a pinch but avoid spicy varieties. Brown sugar can be swapped for raw turbinado at a 1:1 ratio. For the wood pellets, hickory delivers classic flavor, while cherry or pecan add fruitier notes. Short on time? Pre-made BBQ rub can substitute for the dry ingredients, though fresh spices always perform better.

Pork butt freezes beautifully for up to 6 months—vacuum seal for best results. The rub keeps in an airtight container for 3 months. Once cooked, shredded pork stays fresh in the fridge for 4-5 days or freezes for 3 months (the rendered fat may separate but re-incorporates when reheated).

Step-by-Step Instructions for Pellet Grill Pork Butt

Master the technique for fall-apart meat with a perfect bark on your pellet grill.

Step 1: Prepare and Season the Pork Butt

Pat the 4 lb Pork Butt dry with paper towels to ensure the rub adheres properly. I always leave the fat cap intact—it protects the meat during the long cook and contributes to the bark formation. Apply a thin layer of 0.25 cup Yellow Mustard all over the surface; this acts as a binder without adding flavor.

In a bowl, combine the 0.5 cup Brown Sugar, 2 tbsp Kosher Salt, 2 tbsp Black Pepper, 1 tbsp Garlic Powder, 1 tbsp Onion Powder, 1 tbsp Smoked Paprika, and 1 tsp Cayenne Pepper. Press this mixture generously onto every surface of the pork, ensuring an even coating. Let it sit at room temperature for 30 minutes while you prepare the grill.

Step 2: Set Up the Pellet Grill for Low and Slow

Load your pellet grill with the 20 lb Wood Pellets—hickory or applewood both complement pork beautifully. Preheat the grill to 225°F using the smoke or super smoke setting if available. This lower temperature allows the collagen in the pork to break down gradually, resulting in that coveted tenderness.

Once the grill reaches temperature and you see clean, thin smoke (not thick white smoke), place the pork butt directly on the grates, fat-side up. Insert a meat probe into the thickest part of the meat, avoiding the bone. Close the lid and resist the urge to peek—every time you open it, you lose heat and add to the cook time.

Step 3: Smoke and Spritz for Bark Formation

Smoke the pork undisturbed for the first 4-5 hours. After this initial period, begin spritzing every 45-60 minutes with a 50/50 mix of the 0.5 cup Apple Cider Vinegar and 1 cup Apple Juice. This keeps the surface moist, encourages bark formation, and adds a subtle sweet-tangy flavor.

You’ll notice the pork developing a dark, crusty exterior—that’s the bark. Continue smoking until the internal temperature reaches 165-170°F. This is when the stall typically begins, as moisture evaporates from the surface and cools the meat. Don’t increase the temperature; patience is key here.

Step 4: Wrap and Finish for Maximum Tenderness

Once the stall hits, wrap the pork butt tightly in pink butcher paper. This step, known as the Texas crutch, helps power through the stall while preserving the bark. Return the wrapped pork to the grill and continue cooking until the internal temperature reaches 200-203°F.

At this point, the meat should probe like butter with no resistance. The total cook time will likely be 10-12 hours, but rely on temperature and probe tenderness, not the clock. Remove the pork from the grill and let it rest, still wrapped, in a cooler or warm oven for 1-2 hours. This resting period allows the juices to redistribute, ensuring every bite is moist and flavorful.

Make-Ahead Tips for Leftovers

Prep the Night Before

Mix your rub the evening before cooking—I combine the brown sugar, salt, and spices in a jar and shake it up. This lets the flavors meld overnight. Apply the rub to the pork just before cooking, as salt can draw out moisture if left on too long. 🌅

Trim and Store

If you need to trim excess fat from the pork butt, do it 1-2 days ahead and store the meat in the fridge. Keep it in its original packaging or a sealed container to prevent oxidation. I’ve found this actually enhances the flavor as the meat relaxes.

Prep the Spritz

Combine the apple cider vinegar and apple juice in a spray bottle the night before. Store it in the fridge so it’s chilled and ready to go. Cold spritz helps regulate the surface temperature of the meat during the long cook.

Pellet Prep

Check your wood pellets the day before—nothing worse than running out mid-cook. Store pellets in a dry, sealed container to prevent moisture absorption. Hickory or applewood pellets will give you that classic smoke profile for pork. ✨

Resting Setup

Before starting the cook, clear space in a cooler or warm oven for resting the pork. Line it with towels to insulate. This step is crucial—rushing it means losing all those precious juices you worked so hard to develop.

Leftovers Plan

Have airtight containers ready for storing leftovers. Shredded pork freezes beautifully for up to 3 months. I portion mine into 1 lb containers for easy reheating later—perfect for quick meals or sandwiches.
