The pork is everything here. Boston butt (same as pork shoulder) gives you that perfect fat cap for juiciness. Look for 4-5 lb roasts with good marbling at Costco or your butcher—they’re ideal for low and slow. I always go bone-in (more flavor, holds shape better). If you can only find boneless, just trim any large fat chunks so the rub penetrates.
No brown sugar? Maple syrup or honey works in the rub (use half the amount). Out of smoked paprika? Regular paprika plus a pinch of cayenne gets you close. The mustard is just a binder—Dijon or even ketchup can sub in. For the wood chips, hickory gives classic BBQ flavor, but cherry or pecan add nice sweetness. Soak them for 30 minutes before grilling.
Pork keeps in the fridge 3-4 days before cooking. Leftovers? Shred for sandwiches or tacos—they’ll last 4-5 days in the fridge, 3 months frozen. The dry rub keeps indefinitely in a sealed jar. Pro tip: make extra rub, it’s great on ribs too.

Step-by-step instructions for grilled Boston butt pork roast
This method ensures fall-apart tender meat with deep smoky flavor every single time.
Prepare the Dry Rub and Season the Pork
In a bowl, combine the 0.5 cup Brown Sugar, 2 tbsp Kosher Salt, 2 tbsp Black Pepper, 2 tbsp Paprika, 1 tbsp Garlic Powder, 1 tbsp Onion Powder, and 1 tbsp Chili Powder until evenly mixed. The sugar will caramelize beautifully on the grill, creating that perfect bark.
Pat the 4 lb Boston Butt Pork Roast dry with paper towels, then slather it with the 0.25 cup Yellow Mustard—this acts as a binder for the rub. Coat the roast completely with the dry rub mixture, pressing it into the meat so it adheres well. Let it sit at room temperature for 30 minutes while you prep the grill.
Set Up the Grill for Indirect Heat
Prepare your grill for indirect cooking by banking the 2 cups Wood Chips to one side of the charcoal bed or in the smoker box of a gas grill. You want a medium heat zone (around 275-300°F) and a cooler side with no direct flame underneath the pork.
This setup allows the pork to cook low and slow without burning the exterior. Make sure you have enough fuel to maintain the temperature for the entire cook—this could take 4-6 hours. Add a drip pan below the pork to catch fat and prevent flare-ups.
Smoke the Pork Until Probe-Tender
Place the pork roast on the cooler side of the grill, fat-side up. Brush it with a mixture of the 0.25 cup Olive Oil and 2 tbsp Apple Cider Vinegar—this mop sauce adds moisture and a tangy kick. Close the lid and let it smoke undisturbed for the first 2 hours.
After the initial smoke, check the pork every 45-60 minutes, adding more wood chips as needed to maintain a steady smoke. The pork is done when an instant-read thermometer inserted into the thickest part reaches 195-203°F and a probe slides in like butter. The meat should pull apart easily with a fork.
Rest and Shred the Pork
Once the pork reaches the desired temperature, carefully remove it from the grill and transfer it to a cutting board or large bowl. Tent it loosely with foil and let it rest for 30 minutes. This rest period allows the juices to redistribute, ensuring moist, tender meat.
After resting, use two forks or meat claws to shred the pork. Discard any large fat pieces or the bone if your roast was bone-in. The meat should come apart effortlessly, with a beautiful smoky crust on the outside and juicy tenderness throughout. Serve immediately while still warm.
Pro Tips For Making Grilled Boston Butt Pork Roast
- Dry the Meat: Pat the Boston Butt completely dry with paper towels before seasoning—I learned this the hard way after my first few attempts had a weak bark because the rub didn’t stick properly.
- Low and Slow: Keep the grill between 225-250°F and give it 1.5-2 hours per pound. Sounds tedious, but rushing with higher heat just tightens the meat.
- Skip the Cold Start: Pull the pork out of the fridge 30-45 minutes before grilling so it cooks evenly—my grandmother swore by this, and she was right.
- Rest Before Slicing: Tent the roast under foil for at least 20 minutes after grilling to lock in juices—yes, even if you’re starving.
Wine and beer pairings for this grilled boston butt pork roast
Bold Red Wines
A full-bodied Zinfandel from California pairs beautifully with the smoky richness of grilled pork. Its jammy fruit notes complement the caramelized bark. I love Ravenswood for its bold character and affordable price. 🍷
Craft Beer Options
A malty Amber Ale like Fat Tire from New Belgium cuts through the fat while enhancing the pork's depth. For hop lovers, an IPA with citrus notes balances the dish's richness.
Lighter Whites
Surprisingly, a crisp Riesling with a touch of sweetness works well. The acidity cleanses your palate between bites. Dr. Loosen Blue Slate is my go-to for this pairing.
Porch-Friendly Choices
For casual sipping, a hard cider like Angry Orchard Crisp Apple offers refreshing contrast. On hot days, I often grab a Mexican Lager like Modelo Especial—its lightness won't overwhelm the meal.
These pairings highlight the pork's versatility from elegant dinners to backyard hangouts. 💛
