This grilled pork tenderloin is juicy, tender, and full of flavor—no dry, overcooked pork here. The simple marinade adds savory, slightly tangy flavor, while the easy grilling method helps the pork cook evenly and stay moist.
The secret is understanding how pork tenderloin cooks. It’s a naturally lean cut, which means it can dry out quickly if overcooked—but when you grill it to the right temperature and let it rest, it turns out incredibly moist and flavorful. This recipe keeps things simple, reliable, and absolutely delicious.

✨ Before You Begin
✨ Don’t skip trimming: Remove the silver skin so the pork stays tender, not chewy.
✨ This is not pork loin: Pork tenderloin is smaller, leaner, and cooks much faster.
✨ Use a thermometer: This is the difference between juicy and dry pork.
✨ Marinate overnight for best results: This recipe really shines with time—while 4 hours works, an overnight marinade gives the pork the most flavor and tenderness.
Grilled Pork Tenderloin Ingredients + Key Notes
Olive Oil: This forms the base of the marinade, helps the flavor cling to the pork, and encourages a lightly caramelized exterior on the grill.
Sherry + Balsamic Vinegar: This combination gives the marinade balanced acidity. Sherry adds a delicate nuttiness, while balsamic brings richness and subtle sweetness without overpowering the pork.
Rosemary + Thyme: Fresh herbs give the pork that garden-fresh, grilled-meat flavor. Rosemary adds a woodsy, piney note, while thyme brings earthy depth.
Worcestershire Sauce + Soy Sauce: These add savory umami depth and help round out the marinade so the pork tastes flavorful all the way through.
Orange Zest: This adds subtle citrus brightness and aroma without making the marinade too acidic. It lifts the flavor and keeps the pork from tasting flat.
🥣 How to Make Grilled Pork Tenderloin
Make the marinade: In a bowl, whisk together olive oil, sherry, balsamic vinegar, Worcestershire sauce, garlic, herbs, and orange zest.
Marinate the pork: Place the pork tenderloin in a zip-top bag or dish and coat well. Refrigerate for at least 4 hours, preferably overnight.
Preheat the grill: Heat your grill to medium (about 400–450°F). Set up two zones—one direct heat, one indirect.
Sear: Place the pork over direct heat and sear for 2–3 minutes per side until lightly charred.
Finish over indirect heat: Move the pork to the cooler side of the grill and continue cooking until it reaches about 140°F internally.
Rest: Remove from the grill and let rest 5–10 minutes. The temperature will rise to 145°F.
Slice and serve: Slice against the grain for the most tender bites.
🔬 Cooking Science: Why Pork Tenderloin Dries Out
Pork Tenderloin is a very lean cut with little fat or connective tissue. That means:
- It cooks quickly
- It has no fat buffer to protect it
- It dries out easily if overcooked
Cooking to 145°F and allowing for carryover cooking keeps the meat juicy while still safe to eat.
⚠️ Common Mistakes
Overcooking the pork
Going past 145°F will quickly dry it out.
Skipping a thermometer
Visual cues aren’t reliable for this cut.
Not letting it rest
Resting allows juices to redistribute and finish cooking.
Confusing pork loin with tenderloin
They cook very differently—this method is for tenderloin only.
⭐ Pro Tips
⭐ Use a two-zone fire
Sear first, then finish gently over indirect heat for even cooking.
⭐ Pull early
Take the pork off at 140°F and let carryover bring it to 145°F.
⭐ Don’t over-marinate
Over 24 hours can start to break down the texture too much.
⭐ Slice against the grain
This shortens muscle fibers and makes every bite more tender.
What Temperature Should Pork Tenderloin Be?
Pork tenderloin is perfectly cooked at 145°F.
- Safe to eat
- Slightly pink inside
- Juicy and tender
Pulling it slightly early allows for carryover cooking, where the temperature rises as it rests.
How Long to Grill Pork Tenderloin
Most pork tenderloins take 15–25 minutes to grill.
Cook time depends on:
- thickness
- grill temperature
- starting temperature of the meat
👉 Always rely on temperature, not just time.
Best Marinade for Grilled Pork Tenderloin
This marinade is balanced and flavorful without overpowering the pork:
- acid (balsamic + sherry)
- fat (olive oil)
- aromatics (garlic, herbs)
- brightness (orange zest)
It enhances the natural flavor of pork instead of masking it.

Grilled Pork Tenderloin
Ingredients
Marinade
- 1/2 cup sherry
- 1/3 cup balsamic vinegar
- 1/4 cup olive oil
- 2 tablespoons honey
- 3 tablespoons Worcestershire sauce
- 2 tablespoons Dijon mustard
- 2 tablespoons soy sauce
- 2 tablespoons fresh garlic, minced
- 2 tablespoons fresh rosemary
- 1 tablespoon fresh thyme
- 1 teaspoon orange zest
- 1 teaspoon salt
- 1 teaspoon black pepper
Pork:
- 1 1/2 to 2 pounds pork tenderloin
Instructions
Prepare Tenderloin
- Trim any excess fat or silver skin (a tough membrane) from the pork tenderloin (1 1/2 to 2 pounds). This makes a nicer presentation and improves texture.
Make Marinade
- Add all marinade ingredients to a small mixing bowl, then whisk until well combined, and the honey and salt have dissolved.
- Pour marinade into a 1-gallon resealable plastic bag. Remove as much air as possible, seal the bag, and shake to evenly coat. Place the bag on a small rimmed baking sheet to catch any drips. (I use a Nordic Ware 1/4 sheet)
- Refrigerate and marinate for a minimum of 2 hours, or better, overnight. Don't exceed 24 hours.
Set Up 2 Zone Grill
- For Charcoal: Clean and oil the grates. Light a full chimney of charcoal. When the coals are covered in gray ash, pour them onto one side of the grill. Be sure to leave the other side empty for indirect heat. This gives you a hot zone for searing and a cool zone for finishing the cooking process. Put the grill grate back on, cover the grill, and let it preheat for about 5–10 minutes.
- For Gas Grill: Clean and oil the grates. Preheat your gas grill with all burners on high for 10-15 minutes. Once preheated, turn off the burners on one side of the grill, leaving the other side on medium-high heat. This creates your hot zone for searing and cool zone for finishing.
Grill Tenderloin
- Remove the pork tenderloin from the marinade, shaking off excess marinade, and let them come to room temperature for 25-30 minutes before grilling. Discard the marinade.
- Sear: Place the tenderloin over the direct heat and sear on all sides to create a nice crust. This will take about 1.5 minutes per side.
- Cook: Move the tenderloin to the indirect heat side of the grill and continue to cook, turning occasionally, until the internal temperature reaches 145°F, about 12-18 minutes. Keep the lid closed as tenderloin cooks on the indirect side of grill.
- Rest: Remove the tenderloin from the grill and loosely tent with foil, let it rest for 10 minutes before slicing. Serve and enjoy!

Notes
- Use Instant Read Thermometer: It’s really the only accurate way to determine the internal temperature. Here’s the one I use from Amazon. I like it because it’s instant and is moderately priced.
- Marinating Times: Marinate for at least 8 hours for noticeable flavor. You can marinate for 2 hours, but for the best flavor and tenderness, marinate for up to 24 hours. Overnight is ideal.
- Don’t exceed 24 hours, as the acids can begin to break down the meat too much and affect the texture. If you only have 2 hours, it’s better than nothing, but it will only lightly flavor the surface and minimally tenderize.
