There’s nothing like the scent of herbs sizzling on pork loin over an open flame. I developed this method after years of testing at local BBQ competitions, perfecting how to lock in juicy tenderness while achieving a perfect crust.
The secret lies in a simple herb rub combined with precise grilling. Start with a hot grill, sear the filet on all sides, then move to indirect heat to finish cooking. This ensures the outside gets beautifully caramelized while the inside stays moist.
What you get is pork loin with a fragrant, golden-brown crust and meat so tender it nearly falls apart. The herb blend adds depth without overpowering the natural pork flavor.
Serve with grilled vegetables or a fresh salad for a complete meal that impresses every time.

The pork loin is the star here. Look for a center-cut filet with even thickness—about 2 inches is ideal. Most butchers will trim it for you if you ask. Costco has great pre-packaged options too. The fresh herbs matter more than you’d think; whole sprigs from the produce section beat the pre-chopped stuff every time. Don’t skip the Dijon—it’s the glue that holds the rub together.
No fresh rosemary or thyme? Dried works at one-third the amount, but fresh really shines here. If you’re out of Dijon, regular yellow mustard in a pinch (just add a pinch of sugar). Brown sugar can be swapped for honey or maple syrup. For extra smokiness, add a pinch of chipotle powder to the rub. The pork itself? Stick with loin filet—tenderloin cooks too fast for this method.
Pork keeps in the fridge 3-4 days raw, but I’d use it within 2 days for best freshness. Leftovers? Slice thin and reheat in a skillet with a splash of broth. The herb rub can be prepped 1 day ahead—store it in the fridge until ready to use.

Step-by-Step Instructions for Grilled Pork Loin Filet
This method guarantees a juicy, herb-crusted result with perfect grill marks every time.
Step 1: Prepare the Herb Rub
Finely chop the 2 tbsp Fresh Rosemary and 2 tbsp Fresh Thyme, then mince the 4 cloves Garlic Cloves. In a small bowl, combine these with 2 tbsp Dijon Mustard, 1 tbsp Brown Sugar, 1 tsp Smoked Paprika, and 1 tsp Black Pepper.
Slowly whisk in 3 tbsp Olive Oil until the mixture forms a thick paste. This rub will create a flavorful crust while keeping the pork loin filet moist during grilling. The Dijon mustard acts as a binder to help the herbs adhere to the meat.
Step 2: Season and Coat the Pork
Pat the 2 lb Pork Loin Filet dry with paper towels. This step removes excess moisture so the rub sticks better. Season all sides with 2 tsp Kosher Salt, then spread the herb mixture evenly over the surface, pressing it in with your fingers.
Let the coated pork loin filet sit at room temperature for 15-20 minutes while you preheat the grill. This resting period allows the flavors to penetrate the meat and ensures more even cooking.
Step 3: Preheat and Prepare the Grill
Heat your grill to medium-high heat (about 400°F). Use 1 tbsp Vegetable Oil on a folded paper towel to grease the grill grates thoroughly. This prevents sticking and ensures beautiful grill marks on the pork loin filet.
Make sure the grill is fully preheated before adding the meat. You’ll know it’s ready when you can hold your hand about 5 inches above the grates for only 3-4 seconds.
Step 4: Grill to Perfection
Place the pork loin filet on the oiled grates and close the lid. Sear for 4-5 minutes on each side until the crust is deep golden brown and slightly charred in spots. Use tongs to flip—never pierce the meat, as this releases precious juices.
After searing both sides, move the pork loin filet to a cooler part of the grill (or reduce heat to medium) and continue cooking with the lid closed for another 15-20 minutes, or until the internal temperature reaches 145°F.
Step 5: Rest and Slice
Transfer the grilled pork loin filet to a cutting board and tent loosely with foil. Let it rest for 10 minutes—this allows the juices to redistribute throughout the meat, ensuring every slice stays moist and flavorful.
Slice the pork loin filet against the grain into ½-inch thick pieces. The meat should be tender and slightly pink in the center, with a fragrant herb crust on the outside. Serve immediately while warm.
Pro Tips For Making Grilled Pork Loin Filet
- Rest Before Slicing: Let the pork loin rest for 10 minutes after grilling—it keeps the juices from running all over the cutting board instead of staying in the meat.
- Dry the Surface: Pat the pork loin filet completely dry before seasoning; wet meat steams instead of searing, and you’ll lose that good crust.
- Skip the Overcrowding: I learned this the hard way—leave space between filets on the grill so they brown properly instead of steaming in their own juices.
- Crush the Aromatics: Lightly crush the garlic cloves and fresh rosemary before rubbing them on the pork—it releases more flavor and sticks better to the meat.
Best Sauces and Condiments for grilled pork loin filet
Herb-Enhanced Sauces
I love pairing this dish with a rosemary-infused pan sauce. After grilling, deglaze the pan with 1 cup chicken broth and 2 tbsp butter, then add a sprig of fresh rosemary. Simmer for 5 minutes and drizzle over slices. 💡
Mustard Variations
The Dijon in your rub makes a whole-grain mustard sauce a natural fit. Whisk ¼ cup whole-grain mustard with 2 tbsp honey and 1 tbsp apple cider vinegar. This adds a tangy contrast to the smoky pork.
Fruit-Based Glazes
A peach-bourbon glaze complements the herbs beautifully. Simmer 1 cup peach preserves with 2 tbsp bourbon and 1 tsp thyme until syrupy. Brush it on during the last 5 minutes of grilling for a sticky, sweet finish.
Classic Chimichurri
For a fresh, bright option, blend 1 cup parsley, 3 garlic cloves, ¼ cup olive oil, and 2 tbsp red wine vinegar. This Argentine sauce cuts through the richness and highlights the herb crust. 🌿
Spicy Kick
Add heat with a chipotle-lime crema. Mix ½ cup sour cream, 1 tbsp lime juice, and 1 tsp chipotle powder. The smokiness pairs perfectly with the grilled pork and adds a subtle but noticeable spice.

Frequently Asked Questions
How do I know when it’s done?
Use a meat thermometer to check internal temperature—it’s done at 145°F. This ensures juicy pork without overcooking. Let it rest for 10 minutes before slicing.
Can I use dried herbs instead of fresh?
Yes, but use 1/3 the amount since dried herbs are more concentrated. Fresh herbs provide brighter flavor, but dried work in a pinch.
Why does the pork need to rest?
Resting allows juices to redistribute throughout the meat. Skipping this step can result in dry pork as the juices spill out when sliced.
What if my grill has hot spots?
Rotate the filet every 2 minutes during searing to prevent burning. Move to indirect heat if flare-ups occur.
