Pork Loin on the Grill Recipe: Garlic-Rosemary Infused Smokiness

This grilling method delivers a juicy pork loin with smoky depth every time. I rely on a simple garlic-rosemary rub and precise heat control to achieve perfect results.

Direct and indirect heat zones ensure even cooking without drying out the meat. The aroma of fresh herbs on the grill brings back memories of my family’s backyard cookouts.

The pork loin is the star here. Look for a center-cut piece with even thickness—about 2-3 inches—so it cooks uniformly. Most butchers at Whole Foods or your local meat counter will trim and cut it to order. The rosemary and garlic should be fresh (dried won’t give you the same aromatic punch), and I always grab mine from the produce section rather than pre-packaged. Organic pork has better marbling and flavor, but standard works if that’s what’s available.

No fresh rosemary? Dried rosemary at half the amount works in a pinch, but fresh is really worth it. Out of Dijon? Whole-grain mustard adds a nice texture, or regular yellow mustard if that’s all you have. The brown sugar can be swapped for honey or maple syrup (just reduce slightly to avoid burning). For the wood chips, apple or cherry wood gives a milder smoke if hickory feels too strong.

Prep the rub up to 24 hours ahead—flavors meld better. Store uncooked pork in the fridge for no more than 2 days. Leftovers keep well for 4-5 days and make killer sandwiches. Freeze slices for up to 3 months if you’re meal prepping.

Step-by-Step Instructions for Pork Loin on the Grill

This method ensures tender, smoky pork with a flavorful garlic-rosemary crust every time.

Step 1: Prepare the Garlic-Rosemary Rub

In a small bowl, combine the 6 cloves Garlic Cloves, 2 tbsp Fresh Rosemary, 1 tbsp Dijon Mustard, 1 tbsp Brown Sugar, 1 tbsp Apple Cider Vinegar, and 2 tbsp Olive Oil. Stir until the mixture forms a thick paste.

Add 1 tsp Black Pepper and 1 tsp Kosher Salt (reserving the remaining 0.5 tsp Kosher Salt for later). The sugar and vinegar balance the bold flavors while the mustard helps the rub adhere to the 2 lb Pork Loin.

Rub this mixture all over the pork loin, pressing it into the meat so it forms an even coating. Let it sit at room temperature for 30 minutes to allow the flavors to penetrate.

Step 2: Preheat the Grill and Prepare Wood Chips

Soak the 1 cup Hickory Wood Chips in water for at least 30 minutes to ensure they smolder rather than burn. While they soak, preheat your grill to medium-high heat (about 400°F).

Once the grill is hot, clean the grates thoroughly with a grill brush. Use a pair of tongs and a folded paper towel dipped in 1 tbsp Vegetable Oil to oil the grates. This prevents the pork loin from sticking during cooking.

Drain the wood chips and place them in a smoker box or wrap them in heavy-duty aluminum foil with a few holes poked in the top. Position this directly over the heat source to infuse the pork with smoky flavor as it cooks.

Step 3: Grill the Pork Loin to Perfection

Place the pork loin on the oiled grates, fat-side up. Sear it for 4-5 minutes on each side to develop a rich, caramelized crust. Reduce the heat to medium (about 350°F) and continue grilling with the lid closed.

Cook the pork loin until it reaches an internal temperature of 145°F on an instant-read thermometer, about 20-25 minutes total. Avoid flipping the pork more than necessary—each turn should reveal deep golden-brown grill marks.

During the last 10 minutes of cooking, sprinkle the remaining 0.5 tsp Kosher Salt over the pork loin for a final seasoning boost. The wood chips should produce a steady stream of smoke to enhance the flavor.

Step 4: Rest and Garnish

Transfer the pork loin to a cutting board and tent it loosely with aluminum foil. Let it rest for 10 minutes—this allows the juices to redistribute, ensuring every slice stays moist and flavorful.

Slice the pork loin against the grain into ½-inch thick pieces. Garnish with 0.25 cup Fresh Parsley for a pop of color and freshness. Serve immediately while warm, with any accumulated juices spooned over the top.
