Pork Roast on Gas Grill Recipe: Smoky Char With Juicy Slices

This pork roast on gas grill recipe delivers smoky char with juicy slices every time. I developed this method after years of competition BBQ, adapting French techniques to outdoor cooking.

The secret lies in indirect heat and precise temperature control. A simple dry rub enhances the pork's natural flavor without overpowering it, while the grill imparts that coveted smoky depth.

You'll achieve perfectly cooked meat with a caramelized crust outside and tender, moist flesh inside. The aroma alone will have neighbors asking for your secrets.

Pair with grilled vegetables or a crisp salad for a complete meal. This technique works for any pork roast cut.

Ingredients for pork roast on gas grill

Twelve ingredients transform pork shoulder into competition-level grill mastery with smoky depth.

The pork shoulder is non-negotiable here. Bone-in provides superior moisture and flavor—look for even marbling at Whole Foods or a trusted butcher. Avoid pre-seasoned cuts; the dry rub needs a clean canvas. For wood chips, hickory offers classic BBQ aroma, but apple or cherry work beautifully for a sweeter profile. Always soak chips to prevent flare-ups and ensure steady smoke.

No smoked paprika? Regular paprika plus a pinch of cayenne mimics the depth. Short on time? Use 1 tbsp pre-made BBQ rub instead of the spice blend, though fresh is better. The brown sugar can be coconut sugar for a deeper caramel note. If you lack apple cider vinegar, white vinegar with a teaspoon of sugar substitutes adequately. The vinegar’s role is subtle but essential for balancing the rub’s richness.

Store the pork unseasoned in the fridge for up to 3 days before cooking. The dry rub keeps in an airtight container for 6 months. Leftover pork reheats well in a skillet with a splash of water, maintaining moisture for 4-5 days in the refrigerator.

Step-by-step instructions for pork roast on gas grill

Master indirect heat and wood chip smoke for tender, flavorful results every time.

In a small bowl, combine the 1.5 tbsp kosher salt, 1 tbsp coarse black pepper, 2 tsp smoked paprika, 2 tsp garlic powder, 2 tsp onion powder, 1 tsp dried oregano, 1 tsp dried thyme, and 2 tbsp brown sugar. Stir until evenly blended—the spices should be fully distributed with no visible streaks.

Pat the 3 lb pork shoulder roast dry with paper towels to ensure the rub adheres properly. Rub the 2 tbsp olive oil over the entire surface, then apply the spice mixture aggressively, pressing it into the meat. Drizzle with the 1 tbsp apple cider vinegar for balance. Let it sit at room temperature for 30 minutes while you prepare the grill.

Preheat your gas grill to 275°F with all burners on. Once hot, turn off the burners on one side to create an indirect heat zone. Place a smoker box or foil packet containing the 1 cup hickory wood chips (soaked for 30 minutes) directly over the active burner.

Close the lid and allow the wood chips to begin smoking. You want thin, blue smoke—not thick white smoke, which can bitter the flavor. The temperature should stabilize at 250-275°F in the indirect zone, where the roast will cook low and slow for maximum juiciness.

Place the pork shoulder roast bone-side down on the indirect heat side of the grill. Insert a meat thermometer into the thickest part, avoiding the bone. Close the lid and maintain the temperature between 250-275°F throughout cooking.

Smoke the roast undisturbed for 3-4 hours until the internal temperature reaches 195-203°F. At this stage, the connective tissue breaks down, ensuring pull-apart tenderness. If the grill temperature drops, adjust the active burner slightly but avoid opening the lid unnecessarily.

Carefully remove the roast from the grill when it reaches temperature. The exterior should have a deep, mahogany bark from the smoke and spices. Transfer it to a cutting board and tent loosely with foil.

Let it rest for 20-30 minutes—this allows the juices to redistribute throughout the meat. Slice against the grain into ½-inch thick portions. Each slice should glisten with moisture and offer minimal resistance when cut, guaranteeing the promised juiciness in every bite.

Storing and reheating this recipe

Refrigerator Storage

Let your pork roast cool for no more than 2 hours before transferring to an airtight container. I use glass containers with locking lids from my local butcher shop. Store at 40°F or below for up to 4 days. The flavors deepen overnight. ❄️

Freezer Storage

For longer storage, wrap slices tightly in plastic wrap and place in a freezer bag. Squeeze out excess air to prevent freezer burn. Your smoked pork will keep beautifully for up to 3 months without losing moisture or flavor.

Oven Reheating

Preheat oven to 325°F. Place pork in a baking dish with ¼ cup apple cider vinegar and cover with foil. Heat for 15-20 minutes until reaching 165°F internal temperature. This method preserves the bark's texture. 🔥

Skillet Reheating

For quick meals, heat a cast iron skillet over medium-low heat. Add pork slices with a splash of water, cover, and warm for 3-4 minutes per side. I often add a pinch of my dry rub to refresh the flavors.

Microwave Reheating

Place slices on a microwave-safe plate, cover with a damp paper towel. Heat on 50% power for 1-2 minutes, checking frequently. This prevents drying out, though I prefer oven or skillet methods for better results.
