Ingredients for boneless pork loin roast grill
Pitmaster-approved ingredients for a restaurant-quality herb-crusted pork loin that delivers perfect char and juicy interior.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless Pork Loin Roast 🥩 | 2 lb | Center-cut for even cooking |
| Coarse Kosher Salt 🧂 | 2 tbsp | Diamond Crystal preferred |
| Fresh Rosemary 🌿 | ¼ cup | Finely chopped, stems removed |
| Fresh Thyme Leaves 🌿 | ¼ cup | From healthy sprigs |
| Garlic Cloves 🧄 | 8 cloves | Minced for crust |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For crust and searing |
| Fresh Parsley Leaves 🌿 | ⅛ cup | Chopped for garnish |
| Black Peppercorns 🌶️ | 1 tsp | Freshly cracked |
| Dried Mustard Powder 🌶️ | 1 tsp | For depth of flavor |
| Unsalted Butter 🧈 | 2 tbsp | Cold, for basting |
| Fresh Sage Leaves 🌿 | ⅛ cup | Chopped for crust |
The center-cut boneless pork loin is non-negotiable for this technique—it's leaner and more tender than other cuts. Butcher shops often carry premium cuts, but most grocery stores stock quality boneless loin. Look for good marbling and even thickness (about 1.5-inch diameter). If your roast has a thicker end, trim it slightly for even cooking. For a 4-person meal, a 2-pound roast yields generous 6-ounce servings. The Diamond Crystal kosher salt is essential—its coarse texture creates a better crust than table salt, and it dissolves perfectly during cooking.
Fresh herbs elevate this dish dramatically, but dried alternatives work in a pinch—use half the amount and toast them lightly in a dry pan first. Trader Joe's often carries pre-chopped herb blends that save time, though fresh is always superior. For the garlic, peel and mince just before mixing—raw garlic has stronger flavor that mellows beautifully during cooking. The mustard powder adds subtle depth that complements the herbs perfectly. If you're short on time, pre-made herb blends from Penzeys or McCormick work well, though they lack the freshness of homemade. The butter should be cold and cubed—this prevents it from melting prematurely during the sear.
Store fresh herbs wrapped in damp paper towels in a sealed container for up to 5 days. The pork loin should be kept in the coldest part of your fridge until ready to use—never thaw at room temperature. For meal prep, this roast reheats beautifully: 350°F for 10-12 minutes covered with foil, basted with extra olive oil. The herb crust freezes well for up to 3 months if separated from the pork—simply mix the crust ingredients, portion into ice cube trays, and freeze. Thaw overnight in the fridge before using to maintain texture.

Step-by-step instructions for herb-crusted grilled pork loin
Transform a simple boneless pork loin into a restaurant-worthy centerpiece with this precise grilling method.
Prepare the Herb Crust Mixture
In a medium bowl, combine the 0.25 cup fresh rosemary, 0.25 cup fresh thyme leaves, 0.125 cup fresh sage leaves, 8 cloves minced garlic, 1 tsp dried mustard powder, 1 tsp freshly cracked black peppercorns, and 2 tbsp coarse kosher salt. Mix thoroughly to distribute the seasonings evenly. This herb blend will create a fragrant crust that seals in moisture while adding complex flavor.
In a separate small bowl, whisk together the 2 tbsp extra-virgin olive oil and 2 tbsp unsalted butter until combined. The butter adds richness while the olive oil helps the crust adhere to the meat. This mixture should be smooth and emulsified—if it separates, whisk again until fully incorporated.
Coat and Rest the Pork Loin
Pat the 2 lb boneless pork loin roast completely dry with paper towels, removing any excess moisture from the surface. This step is crucial for achieving a proper sear and crispy crust. Using your hands, gently massage the herb mixture into the pork loin, coating all sides evenly. Press firmly to ensure the herbs adhere well.
Transfer the coated pork loin to a plate and let it rest at room temperature for 30 minutes. This resting period allows the seasonings to penetrate the meat slightly and ensures even cooking. The pork should reach room temperature before grilling to prevent uneven cooking—cold meat in the center while the exterior cooks too quickly.
Preheat and Grill the Pork Loin
Preheat your grill to medium-high heat, around 400°F, with the lid closed. Clean the grates thoroughly to prevent sticking. Place the pork loin on the grill, positioning it perpendicular to the grill lines for even cooking. Close the lid and grill for 15 minutes, turning occasionally, until the exterior develops a deep golden-brown crust.
Here's the thing—you want to see those herbs crisp slightly and the pork develop a caramelized crust. If the herbs start to burn before the crust forms, reduce the heat slightly or move the pork to a cooler part of the grill. The internal temperature should reach 145°F after this initial searing phase.
Finish and Rest for Maximum Juiciness
Once the pork loin reaches 145°F internally, transfer it to a cutting board and tent loosely with aluminum foil. Let it rest for 10-15 minutes before slicing. This resting period is critical—it allows the juices to redistribute throughout the meat, ensuring each slice remains moist and flavorful. Don't skip this step, even though it's tempting to serve immediately.
After resting, slice the pork loin into ½-inch thick slices against the grain for maximum tenderness. Garnish each serving with 0.125 cup chopped fresh parsley leaves just before serving to add a pop of color and freshness. The result should be a perfectly grilled pork loin with a fragrant herb crust and juicy interior, ready to impress your guests.
Pro Tips For Making Boneless Pork Loin Roast Grill
- Prep the Garlic Right: Smash those garlic cloves with the flat side of your knife before mincing—it releases more flavor and sticks better to the pork. I used to just chop it, and the aroma was half as strong. Trust me, this tiny extra step makes a real difference when grilling.
- Salt the Pork Early: Coat the pork loin in kosher salt at least 30 minutes before grilling—this lets the seasoning penetrate deeper. I learned this the hard way after dry-brining a roast and getting that perfect crust and juicy meat. Don’t skip the wait time, even if you’re eager to fire up the grill.
- Use a Meat Thermometer: Pull the pork off the grill at 140°F—it’ll rise to 145°F while resting, giving you perfectly medium-rare meat. I used to guess, and more often than not, I ended up with overcooked, dry pork. A $10 thermometer is worth every bite.
- Grill in Two Stages: Sear the pork over high heat first to lock in juices, then move it to indirect heat to finish cooking evenly. After burning three loins on direct heat, I finally got the hang of this method—now it’s foolproof. Keep the lid closed and let the grill do the work.
Make-ahead tips for this recipe
Prep Ahead
Start your herb crust mixture 24 hours ahead—store it in an airtight container in the fridge. The flavors meld beautifully overnight, and you'll save time on prep day. I like to keep the butter and oil separate until mixing day to prevent the herbs from getting soggy. 🌿
Cold Prep Night Before
Pat and season the pork loin the night before and refrigerate uncovered on a wire rack. This dry-brine method creates a better crust than salting right before cooking. I've done this with 3-pound loins and still get perfect results—just double the seasonings proportionally. ❄️
Partial Cook Option
For large gatherings, par-cook the pork to 135°F internal temperature (about 12 minutes per pound on the grill), then refrigerate. Finish on the grill just before serving—this method saves fuel and ensures perfect doneness when reheated. Wrap tightly in foil with a splash of water to maintain moisture. 🔥
Herb Crust Make-Ahead
Make the herb crust 3 days ahead and store in the freezer. Thaw in the fridge overnight before using. I've even pre-portioned crust mixtures into ice cube trays for individual servings—just pop out what you need and mix with fresh herbs if available.
This works especially well for holiday meals. 💫
Grill Prep Shortcut
Preheat your grill 30 minutes ahead of cooking time. I set it to medium heat and let it stabilize—this ensures consistent temperatures when you're ready to cook. For charcoal grills, arrange coals in a two-zone fire (hot and indirect) for better control. 🌡️
Resting Hack
Use the resting time to prep sides! While the pork rests, assemble your salad or roast vegetables. I keep a small slow cooker nearby for keeping side dishes warm during this critical 10-15 minute period. Pro tip: Tent the pork with foil, not plastic wrap—it traps too much steam. 💡

Frequently asked questions
Can I use a thicker pork loin than 2 pounds?
Yes, but adjust your cooking time and prep carefully. For every additional pound, add 10-15 minutes to the grilling time, but monitor the internal temperature closely. A 3-pound roast should reach 145°F in about 25-30 minutes total. For even cooking, trim thicker sections to 1.5-inch thickness and consider starting at medium heat before moving to hotter zones. The herb crust works beautifully on larger cuts too!
What if my grill doesn't get hot enough for a proper sear?
No problem! Start with the pork on the hottest part of your grill for 5 minutes to get that initial sear, then move to indirect heat to finish cooking. If you're using charcoal, bank the coals to one side and place the pork on the cooler side after the initial sear. For gas grills, preheat one burner to high and place the pork there first, then move to medium heat for even cooking. A cast-iron skillet on the grill can also help create a searing surface.
How do I know when the pork is fully cooked?
Use a meat thermometer to check the internal temperature—it should read 145°F in the thickest part. The pork is safe to eat at this temperature, but for slightly pink centers, aim for 140°F. The crust should be golden-brown and slightly crispy. If you don't have a thermometer, cut into the thickest part—juices should run clear, and the meat should feel slightly springy to the touch. Never rely on color alone, as pork can appear cooked before reaching safe temperatures.
Can I grill this pork loin without the herb crust?
The herb crust adds incredible flavor, but you can still make a delicious grilled pork loin with just 2 tbsp olive oil, 1 tbsp kosher salt, and 1 tsp black pepper. For extra flavor, add a rub with 1 tsp garlic powder and ½ tsp smoked paprika. The key is still proper heat control and resting time. The crust is optional, but it's what makes this recipe truly special!
What are the best sides to serve with this grilled pork?
This herb-crusted pork pairs beautifully with light, fresh sides that complement its richness. Try a summer vegetable medley (zucchini, bell peppers, and cherry tomatoes), a crisp green salad with balsamic vinaigrette, or grilled asparagus with lemon zest. For heartier meals, roasted potatoes or a quinoa pilaf with herbs work wonderfully. The crispy crust stands up well to bold flavors, so don't be afraid to experiment with complementary tastes!
