There’s nothing quite like the aroma of applewood smoke mingling with garlic butter as it caresses a pork rib roast on the grill. This method transforms a simple cut into a centerpiece worthy of any gathering.
I’ve spent years refining this technique, blending my pitmaster roots with French precision. The key lies in slow-smoking the roast before finishing it with a rich garlic butter baste that locks in moisture and flavor.
What emerges is a tender, juicy roast with a smoky depth and a golden, buttery crust. The applewood adds a subtle sweetness that complements the pork’s natural richness.
Perfect for Sunday dinners or special occasions, this dish pairs beautifully with roasted vegetables or a crisp salad. Let’s get started.

The pork rib roast is the foundation—opt for bone-in, well-marbled cuts from Whole Foods or a trusted butcher. Applewood chips (from Weber or Traeger) provide the signature smoke, and their subtle sweetness pairs perfectly with pork. For the garlic butter baste, European-style butter (like Plugrá or Kerrygold) offers superior richness. Fresh herbs should be vibrant green, not wilted.
No applewood? Cherry or hickory chips work well too. For a dairy-free baste, coconut oil or vegan butter can substitute. If fresh herbs aren’t available, dried at one-third the amount is acceptable (though less aromatic). Vegetable stock can replace chicken stock for dietary needs. The Dijon mustard can be swapped with whole-grain mustard for a coarser texture.
Store the pork roast in its original packaging for up to 3 days in the fridge, or freeze for 6 months. Soaked wood chips can be kept in water for 24 hours. The garlic butter baste can be made ahead and refrigerated for 1 week—just bring to room temperature before use.

Step-by-Step Instructions for Grilled Pork Rib Roast
Master the technique for perfectly smoked pork with a garlic-herb baste that elevates every bite.
Step 1: Prepare the Roast and Smoking Chips
Begin by soaking the 2 cups Applewood Chips in water for 30 minutes to ensure they produce a steady, flavorful smoke. Meanwhile, pat the 4 lb Pork Rib Roast dry with paper towels—this promotes even browning and better smoke absorption.
Rub the roast all over with the 2 tbsp Olive Oil, then season generously with 2 tbsp Kosher Salt and 1 tbsp Coarse Black Pepper. I press the seasoning into the meat to create a flavorful crust. Let the roast sit at room temperature for 30 minutes while the chips soak.
Step 2: Create the Garlic-Herb Butter Baste
In a small bowl, combine the 0.5 cup Unsalted Butter (softened), 6 cloves Garlic Cloves (minced), 2 tbsp Fresh Rosemary (chopped), 2 tbsp Fresh Thyme (chopped), and 1 tbsp Dijon Mustard. Mix until fully incorporated—the mustard acts as an emulsifier, ensuring the baste clings to the roast.
This compound butter will be used throughout the cooking process to baste the roast, adding layers of flavor. The fresh herbs infuse the butter with aromatic complexity, while the garlic provides a robust, savory note that complements the pork beautifully.
Step 3: Set Up the Grill for Indirect Heat
Prepare your grill for indirect heat by banking the coals to one side (for charcoal) or turning off the burners on one side (for gas). This creates a cooler zone where the roast will cook slowly. Drain the soaked Applewood Chips and scatter them directly over the hot coals or place them in a smoker box for gas grills.
Once the grill reaches 275-300°F and you see thin blue smoke, place the Yellow Onion (quartered) and 3 whole Carrots (peeled and chunked) on the grill grates in the indirect zone. These vegetables will add moisture and flavor as they cook alongside the roast.
Step 4: Smoke the Roast to Perfection
Place the seasoned Pork Rib Roast bone-side down on the grill grates in the indirect heat zone. Insert a meat thermometer into the thickest part of the roast, avoiding the bone. Close the lid and maintain the temperature between 275-300°F.
Every 45 minutes, baste the roast with the garlic-herb butter and the 1 cup Low-Sodium Chicken Stock, using a basting brush or spoon. This keeps the meat moist and builds a flavorful crust. The roast is done when the internal temperature reaches 145°F for medium-rare, which typically takes 2.5-3 hours.
Step 5: Rest and Serve
Once the roast reaches temperature, transfer it to a cutting board and tent loosely with foil. Let it rest for 15-20 minutes—this allows the juices to redistribute, ensuring a moist and tender result.
Slice the roast between the ribs into individual chops and arrange on a platter with the grilled Onion and Carrots. Spoon any remaining garlic-herb butter over the top before serving. The meat should be juicy with a pink center and infused with smoky, herby notes.
Pro Tips For Making Grilled Pork Rib Roast
- Preheat the Chips: Soak applewood chips for 30 minutes before grilling, then drain and add to coals just before cooking—I learned this the hard way after my first batch burned to ash in seconds.
- Score the Fat: Make shallow cuts about 1/4-inch deep in the fat cap so the butter, garlic, and rosemary actually penetrate the meat instead of pooling on top.
- Skip Cold Meat: Let the pork rib roast sit at room temperature for 45 minutes before grilling, or you’ll end up with a dry exterior and undercooked center—yes, even if you’re impatient like me.
- Butter Last: Brush on the garlic-rosemary butter only during the final 10 minutes of grilling to prevent burning, and use more salt than you think since unsalted butter won’t add any.
Make-Ahead Tips for This Recipe
Prep the Roast
Pat the 4 lb Pork Rib Roast dry and season it up to 12 hours ahead. I wrap it in plastic and refrigerate. This lets the salt penetrate deeper for more flavor throughout the meat.
Soak Wood Chips
Soak the 2 cups Applewood Chips for 30 minutes before grilling. For extra convenience, I soak them the night before and store in the fridge. Just drain and use when ready to grill.
Make Garlic Butter
Prep the garlic-herb butter up to 1 week ahead. Mix 0.5 cup Unsalted Butter, 6 cloves Garlic Cloves, 2 tbsp Fresh Rosemary, 2 tbsp Fresh Thyme, and 1 tbsp Dijon Mustard. Store in an airtight container and refrigerate. 💡
Prep Vegetables
Quarter the Yellow Onion and chunk the 3 whole Carrots up to 1 day ahead. Store them in a sealed container in the fridge. This saves time on grill day.
Day-Of Timeline
Remove the seasoned roast from the fridge 1 hour before grilling. This ensures even cooking. I set a reminder to take it out while I prep the grill.
Leftovers Storage
Store cooked pork in airtight containers in the fridge for up to 4 days. It reheats beautifully in a 350°F oven for 15-20 minutes. ✨

Frequently Asked Questions
What internal temperature should I aim for?
Remove the roast when it hits 145°F internally for perfect medium-rare. The temperature will rise to 150-155°F during resting. Use a meat thermometer for accuracy.
Can I use a different type of wood?
Hickory adds stronger smoke, while cherry gives a sweeter note. Avoid softwoods like pine—they can impart bitter flavors.
Why rest the meat before slicing?
Resting for 15-20 minutes lets juices redistribute. Skipping this step means dry meat, as all the moisture will spill out when you cut.
How do I prevent the roast from drying out?
Baste every 45 minutes with the garlic butter and stock. Also, keep the grill at a steady 275-300°F—too hot and it’ll cook too fast.
