The pork loin is where it all starts—bone-in cuts give you that extra juiciness and flavor depth. I always buy mine from Whole Foods or the butcher counter at Costco for the best quality. Look for meat with good marbling; it keeps the filet moist even when seared. If you’re short on time, pre-cut filets work too, just pat them dry before seasoning. The herbs? Fresh rosemary and thyme make all the difference—they add that aromatic punch that elevates the dish beyond basic seasoning.
No fresh herbs? Dried rosemary and thyme work at half the amount, but honestly, they just don’t compare. Want to skip the lemon? Orange zest gives a similar brightness. The butter isn’t just for cooking—slather it on after grilling for that restaurant-style finish. Olive oil is non-negotiable here; extra-virgin is what I use, but any good quality oil will work. The asparagus can be swapped for green beans or zucchini if that’s what you’ve got in the fridge—just toss them on the grill too.
This grilled pork keeps beautifully for 3-4 days in the fridge, wrapped tightly in foil. Reheat in a skillet with a splash of water to keep it moist. I always make extra because it reheats like a dream—freezes for up to 3 months too. The asparagus? Grill them right before serving—they wilt fast. If you’re prepping ahead, keep them separate until the last 10 minutes. The aromas alone will have everyone at the table begging for seconds.

Step-by-step instructions for grilled pork loin filet
Here’s how to achieve that perfect balance of crispy exterior and juicy interior every time.
Prepare the Pork Loin Filet for Maximum Flavor
Pat the 2½ lb pork loin filet completely dry with paper towels—this is crucial for developing that crispy crust. I like to use two layers of paper towels to get it truly dry. The bone-in cut adds natural flavor, so leave it intact if your filet includes one.
In a small bowl, combine the 1½ tablespoons kosher salt, 1 tablespoon black pepper, 1 tablespoon garlic powder, 1 tbsp fresh rosemary, and 1 tbsp fresh thyme. Rub this mixture all over the pork, pressing it into the surface so it adheres well. Let the seasoned pork sit at room temperature for 30 minutes while you prep the grill.
Create the Perfect Grill Setup
Heat your grill to medium-high heat (about 400°F). I prefer using charcoal for that authentic smoky flavor, but gas grills work too. Clean the grates thoroughly first—any leftover food can cause sticking. Brush the grates with ¼ cup of the olive oil to help prevent the pork from sticking.
While the grill heats, prepare the asparagus spears by trimming the tough ends and tossing them with the remaining ¼ cup olive oil, 1 tbsp lemon zest, and a pinch of salt. This gives them a bright, citrusy flavor that pairs perfectly with the pork. Keep them separate until ready to grill.
Grill the Pork to Juicy Perfection
Place the pork loin filet on the hot grill, positioning it perpendicular to the grates for even cooking. Grill for 12-15 minutes on each side, or until the internal temperature reaches 145°F when measured with a meat thermometer. Here’s the thing—don’t flip too soon. You’ll know it’s ready to flip when you see grill marks form and the surface becomes golden brown.
During the last 5 minutes of grilling, add the asparagus spears to the grill. They should cook quickly, turning tender-crisp in about 4-5 minutes. Keep them moving on the grill so they don’t overcook.
Rest and Finish with Herb Butter
Transfer the pork to a cutting board and tent loosely with aluminum foil. Let it rest for 10-15 minutes—this is where the magic happens. The juices redistribute throughout the meat, ensuring every bite stays moist and flavorful. Don’t skip this step, no matter how tempting it is to cut into it immediately.
While the pork rests, melt the ¼ cup butter in a small saucepan over low heat. Stir in the 2 tbsp lemon juice and let it warm through. This herb butter will add a luxurious finish to your pork.
Slice and Serve with Confidence
After resting, slice the pork loin filet into ½-inch thick medallions. Brush each slice generously with the warm herb butter. The butter should be just warm enough to melt slightly when it hits the hot pork, creating a beautiful glaze.
Arrange the slices on a platter with the grilled asparagus spears alongside. The combination of crispy, juicy pork with tender asparagus and that bright lemon-herb butter makes this dish truly special. Serve immediately while everything is at its peak temperature and flavor.
Pro Tips For Making Pork Loin Filet Recipe Grill
- Wait for Grill Marks: The golden-brown crust isn’t just for looks—it’s the flavor. I used to flip too early, and the pork always ended up gray and dry. Let those perfect grill marks form (about 3-4 minutes per side) before flipping, even if it means waiting a little longer. Your patience will pay off with that irresistible texture.
- Salt the Pork Aggressively: Kosher salt is your friend here, but don’t be shy. The recipe calls for 1½ tablespoons, but if your pork feels underseasoned after the initial rub, add a little more—especially if you’re using bone-in, which can hide some of the seasoning. Trust me, dry-heat cooking amplifies saltiness, so you’ll thank yourself later.
- Oil the Grates Like Your Life Depends on It: Skimping on the olive oil here is a mistake. Brush those grates with 2 tablespoons of the ¼ cup extra-virgin olive oil before the pork hits the heat—it’s the only thing keeping your filet from sticking like glue. I learned this after wrestling with a stuck pork chop that looked like it had been glued to the grill. (Yes, even if you’re impatient like me.)
- Rest the Pork—Really: I know, I know—you’re starving, and the pork looks perfect. But cutting into it too soon is how you end up with dry slices. Tent that pork with foil and let it rest for the full 10-15 minutes. The juices need time to redistribute, and that’s the difference between a juicy masterpiece and a sad, shriveled mess. (Your future self will thank you.)
Creative variations of these flavors
Smoky BBQ Twist
I love adding a touch of smokiness to my grilled pork loin—it pairs beautifully with the herb crust. After seasoning the pork, I sprinkle 1 tablespoon of Penzeys smoked paprika over the top before grilling.
The grill itself will add natural smoke, but this extra step gives that classic BBQ vibe. I also add 1 teaspoon of liquid smoke to the herb butter for an even deeper smoky finish. The contrast of the crispy exterior and smoky undertones makes every bite exciting.
Honey-Glazed Sweetness
For a sweeter profile, I swap out half the olive oil in the asparagus prep for 1 tablespoon of honey mixed with 1 teaspoon of Dijon mustard. Toss the asparagus in this mixture before grilling—the caramelized sweetness balances the savory pork perfectly.
I also drizzle 1 tablespoon of honey mixed with 1 teaspoon of apple cider vinegar over the sliced pork before serving. This creates a glossy glaze that’s irresistibly sticky and flavorful. 🍯
Spicy Chipotle Kick
If you love heat, I recommend adding 1 teaspoon of Penzeys chipotle powder to the initial seasoning blend. This gives the pork a subtle smoky-spicy depth that complements the rosemary and thyme. For extra kick, I like to mix ½ teaspoon of cayenne pepper into the herb butter.
The spicy butter adds a fiery finish that wakes up your palate. Honestly, the first bite is always a little surprising—it’s that perfect balance of heat and richness.
Herb-Crusted with Parmesan
For a cheesy twist, I sprinkle ¼ cup freshly grated Parmesan cheese over the pork just before the final 2 minutes of grilling. The cheese melts slightly, creating a delicious crust that adds umami depth.
I also add 1 tablespoon of chopped parsley to the herb butter for a fresh finish. The combination of herby, cheesy, and buttery flavors makes this version feel like a gourmet dish. It’s one of my go-to variations when I want to impress guests.
Asian-Inspired Sesame Glaze
I love experimenting with global flavors, so I toss the asparagus with 1 tablespoon of toasted sesame oil and 1 teaspoon of soy sauce before grilling.
For the pork, I brush on a glaze made from 2 tablespoons soy sauce, 1 tablespoon honey, 1 tablespoon rice vinegar, and 1 teaspoon grated ginger after grilling. The sesame glaze adds a nutty, umami richness that contrasts beautifully with the pork’s natural sweetness.
It’s a flavor profile that always surprises and delights. 🌟

Frequently asked questions
Why is it important to pat the pork loin filet completely dry before grilling?
Drying the pork thoroughly is key for developing that perfect crispy crust on the outside. The moisture creates steam, which prevents the seasoning from sticking and keeps the exterior from browning properly. Using two layers of paper towels ensures every bit of dampness is absorbed before seasoning.
How do I know when the pork loin filet is done on the grill?
Use a meat thermometer to check the internal temperature—it should reach 145°F for juicy perfection. You’ll also see golden-brown grill marks form and the surface become deeply caramelized. Let the pork rest 10-15 minutes before slicing to lock in all those delicious juices.
Can I use bone-less pork loin filet instead of bone-in?
Yes, but bone-in adds extra flavor and moisture. If using boneless, make sure to trim any excess fat and double-check the 145°F internal temp to avoid dryness. The bone-in version naturally stays juicier due to its collagen-rich structure.
What’s the best way to reheat leftover grilled pork loin?
Reheat in a skillet over medium-low heat with a splash of water or broth for 2-3 minutes per side. This keeps it moist and prevents drying out. Avoid microwave reheating, as it can make the meat rubbery. Serve with a quick drizzle of herb butter for extra flavor.
