This grilled bone in pork loin roast recipe delivers applewood-infused juiciness every time. The bone adds depth while the grill imparts smoky complexity that elevates the natural pork flavor.
I developed this method after years of competition cooking, perfecting the balance between tender meat and caramelized crust. The applewood chips create a subtle sweetness that complements the pork's richness without overpowering it.
You'll achieve fall-off-the-bone tenderness with a crispy exterior, thanks to a controlled grilling environment and proper internal temperature monitoring. The result is a centerpiece worthy of any gathering.
Serve with roasted seasonal vegetables and a tangy apple compote to complete the meal. This technique guarantees professional results for your next cookout.
Ingredients for Grilled Bone in Pork Loin Roast
Twelve quality ingredients deliver competition-level flavor in this bone-in pork loin masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Bone-In Pork Loin Roast 🥩 | 4 lb | Center-cut, rib bones frenched |
| Applewood Chips 🌳 | 2 cups | Soaked in water 30 minutes |
| Coarse Kosher Salt 🧂 | 1 ½ tbsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | 1 tbsp | Coarse grind for texture |
| Garlic Cloves 🧄 | 6 cloves | Minced for rub |
| Fresh Rosemary 🌿 | 2 tbsp | Finely chopped stems discarded |
| Fresh Thyme 🍃 | 1 tbsp | Leaves stripped from stems |
| Olive Oil 🫒 | ¼ cup | Extra-virgin for herb infusion |
| Dijon Mustard 🟡 | 2 tbsp | Whole grain preferred |
| Light Brown Sugar 🥜 | 2 tbsp | Packed for caramelization |
| Apple Cider Vinegar 🍏 | 1 tbsp | For acidity balance |
| Butter 🧈 | 4 tbsp | Unsalted, for basting |
The pork loin is the foundation—source from a trusted butcher like Whole Foods or a local shop for consistent quality. Look for center-cut roasts with even marbling; the bone should be frenched (cleaned of meat) for presentation. Applewood chips are non-negotiable here; Western BBQ brands offer reliable quality. Avoid mesquite—it overpowers the pork’s natural sweetness.
No applewood chips? Cherry or hickory at half the quantity work in a pinch. Dried rosemary and thyme can substitute fresh at one-third the amount. For the rub, honey instead of brown sugar adds a different sweetness profile. The Dijon mustard binds the rub—whole grain provides texture, but smooth works fine. Skip the vinegar if you must, but it brightens the richness.
Store the pork untrimmed in its original packaging 1-2 days max. Fresh herbs wrapped in damp paper towels last 5 days refrigerated. Applewood chips keep indefinitely in a sealed container. Leftovers reheat best sliced and warmed in a skillet with a splash of broth to restore moisture.

Step-by-Step Instructions for Grilled Bone In Pork Loin Roast
Master the technique for perfectly charred exterior and tender, juicy meat with applewood depth.
Prepare the Herb Rub and Pork
Combine the 1.5 tbsp Coarse Kosher Salt, 1 tbsp Freshly Ground Black Pepper, minced 6 cloves Garlic Cloves, chopped 2 tbsp Fresh Rosemary, and 1 tbsp Fresh Thyme in a bowl. This aromatic blend forms the foundation of your flavor profile.
Pat the 4 lb Bone-In Pork Loin Roast completely dry with paper towels. The drier the surface, the better the sear. Rub the herb mixture all over the pork, pressing firmly to adhere. Let it sit at room temperature for 30 minutes while you prepare the grill.
Infuse the Olive Oil and Prepare the Grill
In a small saucepan, gently warm the 0.25 cup Olive Oil with the 2 tbsp Dijon Mustard, 2 tbsp Light Brown Sugar, and 1 tbsp Apple Cider Vinegar over low heat for 2-3 minutes. Stir until the sugar dissolves completely and the mixture becomes fragrant.
Soak the 2 cups Applewood Chips in water for 30 minutes if not pre-soaked. Drain them just before use. Set up your grill for indirect heat: bank the coals to one side for charcoal or turn off one set of burners for gas. Preheat to 375°F.
Sear and Smoke the Roast
Place the applewood chips directly on the hot coals or in a smoker box for gas grills. Position the pork on the grill grates over direct heat. Sear for 4-5 minutes per side until deeply browned. The sugar in the rub will caramelize, creating a beautiful crust.
Move the roast to the indirect heat side of the grill. Cover and cook for 1 to 1.5 hours, maintaining the temperature at 375°F. Baste the pork every 20 minutes with the warm olive oil mixture. The internal temperature should reach 145°F.
Rest and Finish with Butter
Transfer the pork to a cutting board and tent loosely with foil. Let it rest for 15 minutes. This allows the juices to redistribute throughout the meat. The internal temperature will rise to 150-155°F during this time.
Melt the 4 tbsp Butter and brush it over the roast just before slicing. This final step adds a glossy finish and an extra layer of richness. Carve between the bones into thick slices and serve immediately, ensuring each portion gets some of the flavorful crust.
Pro Tips For Making Grilled Bone In Pork Loin Roast
- Preheat the Grill: Get your grill screaming hot—450°F at least—before the pork hits the grates. I learned this the hard way after serving dry, gray meat from a lukewarm start.
- Soak the Wood Chips: Submerge those applewood chips in water for 30 minutes first. Sounds like a hassle, but it stops them from burning up before they can infuse that smoky sweetness.
- Don’t Rush the Rest: Pull the roast at 145°F internal temp, tent it loosely with foil, and give it a solid 15 minutes to redistribute the juices. My first few pork loins were carved too soon and bled all over the cutting board.
- Crush the Garlic: Smash the garlic cloves with the flat of your knife before mincing—it releases way more flavor into the rub. I used to just chop it fine and wondered why the taste was so mild.
Essential Equipment for Perfect Results
Grill Setup Essentials
For this recipe, I recommend a kettle-style charcoal grill like the Weber Original for superior heat control. The dome shape helps circulate smoke evenly. A dual-zone fire is non-negotiable for searing and indirect cooking.
Temperature Control Tools
Invest in a digital probe thermometer—I use ThermoWorks Smoke for accuracy. An instant-read thermometer helps verify doneness. Maintain 375°F consistently; charcoal grills may need occasional adjustment.
Smoking Equipment
A cast iron smoker box works perfectly for gas grills. For charcoal, simply place soaked applewood chips directly on hot coals. I prefer chunks over chips for longer burns. Avoid overloading—2 cups provides ideal smoke without bitterness. 🌡️
Basting Tools
Use a silicone basting brush for applying the olive oil mixture. It withstands high heat better than natural bristle brushes. Keep a small saucepan on the grill's edge to keep your basting liquid warm.
Resting and Serving
A large cutting board with a juice groove catches precious drippings. Tent with heavy-duty foil during resting. I serve on a pre-warmed platter to maintain temperature. The bone-in presentation deserves proper serving tools.
Cleanup Must-Haves
Keep a grill brush with brass bristles and a spray bottle of water handy. Clean grates immediately after cooking while they're hot. This prevents residue buildup that could affect your next cookout. 💪

Frequently Asked Questions
Why use bone-in for pork loin?
The bone enhances flavor and helps maintain moisture during grilling. It also creates a more impressive presentation when sliced between the ribs. Expect more forgiving cooking with less risk of drying out.
Can I cook this on a gas grill?
Use a smoker box or foil pouch for the applewood chips. Maintain 375°F and follow the same timing. Gas grills may need more frequent basting to prevent drying.
How do I prevent dry pork?
Don't overcook! Pull at 145°F internal temperature and let rest 15 minutes. Basting every 20 minutes with the oil mixture also helps retain moisture.
What if I don't have applewood?
Cherry or hickory work well, but use half the quantity. Avoid mesquite—it's too strong. Soak chips for 30 minutes regardless of wood type.
