Grilled Pork Loin Recipe: Juicy and Flavorful Every Time

As a pitmaster with a passion for blending smoke-cooking tradition with classic French technique, I’ve perfected the art of grilling pork loin to achieve juicy results every time. My secret lies in precise temperature control and a special rub that adds depth without overpowering the meat.

By following my method, you’ll achieve a perfectly grilled pork loin with a crispy crust and tender interior, cooked to a safe internal temperature of 145°F. Let’s get started with the recipe!

For the best results, use a center-cut pork loin—more even cooking. Most grocery stores carry them pre-tied. If you’re feeling fancy, butcher’s twine at the hardware store works too. I prefer Kirkland Signature pork from Costco for consistency, but any good butcher will do. The key is to get a nice, even thickness so it cooks uniformly.

No smoked paprika? Regular paprika works, but you’ll lose that deep smoky flavor. Penzeys has great smoked paprika if you want to splurge. For the rub, mix everything together the night before—flavors meld beautifully. If you’re skipping the Worcestershire, just bump up the apple cider vinegar to 2 tablespoons. Fresh thyme is ideal, but dried works at one-third the amount.

This keeps beautifully in the fridge for 3-4 days. Slices make great sandwiches. Freeze individual portions for up to 3 months. When reheating, add a splash of broth to keep it moist. Let it rest at room temperature for 15 minutes before slicing—makes all the difference.

Step-by-Step Instructions for Grilled Pork Loin

Follow these precise steps to achieve perfectly grilled pork loin that’s both juicy and full of flavor.

Step 1: Prepare the Spice Rub

In a small bowl, combine the 2 tbsp Brown Sugar, 1 tbsp Smoked Paprika, 1 tbsp Kosher Salt, 2 tsp Black Pepper, 1 tsp Garlic Powder, 1 tsp Onion Powder, and 1 tsp Dried Thyme. Mix these dry ingredients thoroughly until they’re evenly distributed. The mixture should have a uniform color and texture, indicating that the spices are well combined.

This spice rub is crucial for adding depth and complexity to your pork loin. By mixing it thoroughly, you ensure that every bite will have a balanced flavor. I like to use a small whisk or fork to blend the spices, as it helps to break up any clumps and ensures an even distribution.

Step 2: Season the Pork Loin

Place the 1.5 lb Pork Loin on a clean, flat surface. Evenly coat all surfaces of the pork loin with the prepared spice rub, pressing the spices gently onto the meat to ensure they adhere. Make sure to cover every area, including the sides and any crevices, to maximize flavor penetration.

The key here is to be generous with the spice rub but not to overdo it. You want a nice, even coating that will enhance the pork’s natural flavors without overpowering them. After applying the rub, let the pork loin sit at room temperature for 30 minutes before grilling to allow the meat to relax and cook more evenly.

Step 3: Grill the Pork Loin

Preheat your grill to medium-high heat, aiming for a temperature of around 400°F. Brush the grates with the 2 tbsp Olive Oil to prevent sticking. Place the pork loin on the grill, away from direct flames if possible, to avoid charring. Close the grill lid and cook for 5-7 minutes per side, or until a nice crust forms and the internal temperature reaches 145°F.

During grilling, you might notice some flare-ups due to the fat rendering from the pork loin. If this happens, simply rotate the pork loin to a cooler part of the grill until the flames subside. The goal is to achieve a nice, even sear without burning the exterior. Use a meat thermometer to check for doneness, as this is the most reliable method.

Step 4: Rest and Slice

Once the pork loin is cooked to the correct temperature, remove it from the grill and transfer it to a cutting board. Tent it loosely with aluminum foil to retain heat and let it rest for 10-15 minutes. This resting period is crucial as it allows the juices to redistribute throughout the meat, ensuring that each slice is juicy and flavorful.

After resting, slice the pork loin against the grain into 1-inch thick slices. The meat should be tender and slightly firm to the touch, with a hint of pink in the center. Serve immediately, garnished with the 2 sprigs Fresh Rosemary and accompanied by your choice of sides.

Flavor Customization for This Dish

Spicy Korean BBQ Variation

Transform your grilled pork loin into a spicy Korean BBQ masterpiece by adding 1-2 tsp Gochugaru (Korean chili flakes) to the dry rub. This creates a bold, spicy crust that pairs perfectly with a sweet gochujang glaze brushed on during the last 5 minutes of grilling. 🔥

Herb Crusted Delight

For a more herbaceous flavor profile, mix 2 tbsp chopped fresh rosemary and 1 tbsp chopped fresh sage into the dry rub. The aromatic herbs complement the pork’s richness beautifully. Consider adding 1 tsp lemon zest for brightness. This creates a sophisticated flavor profile perfect for special occasions.

Southern-Style Mustard Crust

Create a tangy Southern-style crust by mixing 2 tbsp whole-grain mustard with the dry rub ingredients. The mustard adds a nice tanginess that cuts through the richness of the pork. For an extra layer of flavor, brush the pork with a mixture of 1 tbsp honey and 1 tbsp apple cider vinegar during the last 5 minutes of grilling.

Asian-Inspired Soy Glaze

For an Asian-inspired flavor, create a glaze by whisking together ¼ cup soy sauce, 2 tbsp honey, 1 tbsp rice vinegar, and 1 tsp grated ginger. Brush this glaze over the pork loin during the last 10 minutes of grilling. The result is a sweet and savory flavor profile with a beautiful caramelized crust.

Smoky Chipotle Flavor

Add a smoky, spicy kick by incorporating 1-2 chipotle peppers in adobo sauce (minced) into the dry rub. This adds depth and a moderate level of heat. For an extra smoky flavor, consider adding 1 tsp liquid smoke to the marinade. This variation is perfect for those who love spicy, smoky BBQ flavors.

Garlic Parmesan Italian-Style

Give your pork loin an Italian twist by mixing 2 cloves minced garlic and ¼ cup grated Parmesan cheese into the dry rub. The garlic and Parmesan create a savory, umami flavor that pairs well with a side of roasted vegetables or a fresh salad. Brush with 1 tbsp olive oil before grilling for a crispy crust.
