The pork shoulder is ideal for this method—its marbling ensures juiciness. Look for a well-marbled roast at Whole Foods or Costco. Hickory chips are essential for that authentic smoke; avoid mesquite, which can overpower. For herbs, fresh rosemary and thyme from the farmers market pack the most punch (dried works in a pinch, but cut the amount by half).

No hickory chips? Apple or cherry wood gives a milder, sweeter smoke. Swap pork shoulder for pork loin (cook to 145°F instead of 195°F) if you prefer leaner meat. Dry mustard at half the amount can replace Dijon, though the flavor won’t be as complex. The apple cider vinegar is key—don’t substitute white vinegar, as it lacks depth.

The roast can marinate overnight for deeper flavor. Leftovers keep for 4-5 days in the fridge or 3 months frozen. Reheat gently in a covered dish with a splash of broth to maintain moisture.

Step-by-Step Instructions for Boneless Pork Roast on the Grill

Master the technique for achieving deep smoky flavor and perfect doneness with this method.

Step 1: Prepare the Herb Paste and Season the Roast

In a small bowl, combine the 0.25 cup olive oil, 2 tbsp Dijon mustard, 1 tbsp apple cider vinegar, 1 tbsp brown sugar, 1 tsp smoked paprika, and the chopped leaves from the 4 whole fresh rosemary sprigs and 6 whole fresh thyme sprigs.

Stir until the mixture forms a thick paste. Pat the 3 lb boneless pork shoulder roast dry with paper towels, then rub the paste evenly over all surfaces. This creates a flavorful crust that locks in moisture during grilling.

Season generously with the 2 tbsp coarse kosher salt and 1 tbsp freshly ground black pepper, pressing the seasoning into the meat so it adheres well. Let the roast sit at room temperature for 30 minutes while you prepare the grill.

Step 2: Set Up the Grill for Indirect Heat with Smoke

Soak the 2 cups hickory wood chips in water for 30 minutes to ensure they smolder rather than burn. Drain them just before use. This step is crucial—dry chips will ignite and create bitter smoke rather than the sweet, aromatic smoke we want.

Prepare your grill for indirect heat by banking the coals to one side (for charcoal) or turning off one set of burners (for gas). Place the soaked wood chips directly on the hot coals or in a smoker box for gas grills. Preheat the grill to 325-350°F.

You want a consistent, moderate heat that allows the pork to cook through without burning the exterior. The temperature should hold steady in this range throughout the cooking process.

Step 3: Sear and Smoke the Roast

Place the seasoned roast directly over the heat source and sear for 3-4 minutes per side until a deep, rich crust forms. Watch for the edges to turn dark golden brown—this indicates the Maillard reaction is creating complex flavors.

Move the roast to the indirect heat side of the grill, cover, and cook for 1.5 to 2 hours. Add the 6 cloves garlic cloves to the coals or smoker box during the last 30 minutes of cooking for an extra layer of aroma. The pork is done when an instant-read thermometer inserted into the thickest part reads 195-203°F.

Resist the urge to open the grill lid frequently. Each time you do, you lose heat and smoke, which extends the cooking time and reduces the smoky flavor infusion.

Step 4: Rest and Serve

Transfer the roast 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 each slice is moist and flavorful.

The internal temperature will rise by 5-10°F during resting, so remove the roast from the grill when it’s just shy of your target temperature. Slice against the grain into ½-inch thick pieces and serve immediately.

The finished roast should have a dark, crusty exterior with a pink smoke ring just beneath the surface. The meat should pull apart easily with a fork, offering a perfect balance of smoky depth and herb-infused tenderness.

Best Sauces and Condiments for boneless pork roast grill

Classic BBQ Sauce

I love pairing this with a tangy Kansas City-style sauce. The molasses base complements the smoky hickory perfectly. Look for Sweet Baby Ray’s Original at your local market—it’s my go-to for its balanced sweetness and spice. 🌟

Apple Cider Glaze

Reduce 1 cup apple cider with 2 tbsp apple cider vinegar and 1 tbsp brown sugar until syrupy. The acidity cuts through the richness while echoing the vinegar in the herb paste. Brush it on during the last 10 minutes of grilling.

Chimichurri Sauce

Blend 2 cups fresh parsley, 4 garlic cloves, ¼ cup olive oil, and 2 tbsp red wine vinegar. ThisArgentine sauce adds bright, herby notes that work beautifully with the rosemary and thyme. I forage wild parsley for an extra earthy touch.

Spicy Mustard Sauce

Whisk ½ cup Dijon mustard with 2 tbsp honey, 1 tbsp smoked paprika, and 1 tsp cayenne. The heat enhances the smoky char while the honey balances the sharpness. Perfect for those who love a kick. 🔥

Garlic Butter Baste

Melt ½ cup unsalted butter with 4 minced garlic cloves and 1 tbsp fresh thyme leaves. Baste the roast during the last 30 minutes of cooking for an aromatic finish. Use the leftover butter for dipping.
