Beef Tenderloin Recipe Pellet Grill: Smoky, Juicy Perfection in One Smoke

Cooking beef tenderloin on a pellet grill transforms a simple cut into smoky, juicy perfection that rivals a high-end steakhouse. The key lies in balancing low-and-slow smoking with precise temperature control—something I perfected after years of experimenting with my family’s backyard cookouts.

That first whiff of hickory smoke still brings me back to those childhood summers, but now I’ve refined the technique for restaurant-quality results at home.

This recipe starts with a simple seasoning blend—just salt, pepper, and a touch of garlic powder—to let the natural beef flavor shine through. The pellet grill’s ability to maintain steady temperatures without flare-ups makes it ideal for achieving that perfect medium-rare finish.

We’ll sear the tenderloin over direct heat first, then move it to indirect smoke for even cooking, ensuring every bite is tender and infused with wood-fired aroma.

By the time you pull it from the grill, you’ll have a juicy, caramelized exterior with a pink center at 145°F, resting for 10 minutes before slicing. The pellet grill’s gentle smoke imparts depth without overpowering the beef’s richness, and the results are foolproof—no guesswork, just consistent perfection.

Serve with roasted garlic mashed potatoes or grilled asparagus for a complete meal that’s as impressive as it is delicious.

The beauty of pellet grills is their versatility—this same method works for holidays, weeknight dinners, or special occasions. Whether you’re feeding a crowd or treating yourself to a steakhouse-worthy meal, this recipe delivers every time. Let’s get started on creating your most tender, smoky tenderloin yet.

The tenderloin is the star—center-cut, trimmed of fat gives you the most tender, uniform texture. Look for 3-pound pieces from your local butcher or grocery store’s premium section. I always buy mine from Whole Foods or Costco when I can, but even regular grocery stores carry quality cuts. The key is bright red color and firm texture—avoid anything with grayish hues or excessive marbling. Let it sit at room temperature for 1 hour before grilling to ensure even cooking.

No hickory pellets? Mesquite or cherry wood pellets work beautifully for a different smoky profile. Fresh rosemary and thyme are ideal, but dried herbs at half the amount get you close. Want more depth? Add 1 tsp of smoked paprika to the seasoning blend. The apple cider vinegar isn’t just for basting—it tenderizes the meat and adds a subtle tang. For the butter basting, unsalted is non-negotiable—salted can make the meat taste overly briny. Skip the butterfly pepper if you’re sensitive to heat, but it adds a fun little kick.

This tenderloin reheats beautifully—wrap tightly in foil and store in the fridge for up to 3 days. For longer storage, freeze portions for up to 3 months. I like to slice it thin before freezing so I can pull out just what I need. The pellets keep for 6-12 months if stored in a cool, dry place. Pro tip: pre-soak pellets for 30 minutes if you’re using them in damp conditions—they’ll smoke more consistently. The basting butter? Use within 1 week once opened, or freeze in ice cube trays for single-use portions.

Step-by-step instructions for smoked beef tenderloin on a pellet grill

Here’s the method that delivers melt-in-your-mouth tenderness with a perfect smoky crust every time.

Remove the beef tenderloin from the refrigerator and let it sit at room temperature for 30 minutes before cooking. This ensures even cooking throughout. Pat the surface completely dry with paper towels—moisture is the enemy of that perfect sear we’re after.

In a small bowl, combine the 1½ tablespoons kosher salt, 1 tablespoon freshly ground black pepper, and 1 teaspoon garlic powder. Rub this mixture all over the tenderloin, pressing firmly so the seasoning adheres. Don’t forget to season the ends as well—this prevents them from drying out during cooking. For extra depth, sprinkle the 1 teaspoon butterfly pepper evenly over the surface. The heat will mellow as it cooks, adding just a subtle kick.

Fill your pellet grill with 2 pounds of hickory wood pellets—this wood delivers that classic, authentic smoky flavor that pairs perfectly with beef. Set the grill to maintain a steady 225°F temperature. Preheat for 15 minutes to ensure a consistent cooking environment. I like to place a water pan in the grill during the cook to help maintain moisture in the air.

Once the grill reaches temperature and you see clean, blue smoke (not thick white smoke), place the seasoned beef tenderloin directly on the grates, fat side up. The natural juices will render and baste the meat as it cooks. Close the lid and resist the urge to peek—every time you open it, you lose heat and extend cooking time.

Smoke the beef tenderloin undisturbed for 2 to 2½ hours, or until the internal temperature reaches 125°F at the thickest part. This low-and-slow approach ensures the meat stays incredibly tender while developing deep, smoky flavors. The reason we stop at 125°F is that beef tenderloin continues to cook as it rests, carrying over to a perfect 130-135°F—ideal for medium-rare doneness.

During this time, prepare your basting mixture by combining the ¼ cup extra-virgin olive oil, ½ cup butter, ¼ cup chopped fresh rosemary, ⅛ cup fresh thyme leaves, and 1 tablespoon apple cider vinegar in a small saucepan. Melt over low heat, then strain to remove any herb bits. Keep this mixture warm—it’s what will elevate your tenderloin from good to extraordinary.

Once the internal temperature hits 125°F, remove the beef tenderloin from the grill and transfer it to a cutting board. Using a pastry brush, generously baste the surface with the warm herb butter mixture. Then, return it to the grill and close the lid for 15 minutes to allow the basting to set and the crust to form.

After 15 minutes, baste the tenderloin one final time and let it rest for 15 minutes before slicing. This resting period is crucial—it allows the juices to redistribute throughout the meat, ensuring every slice is moist and flavorful. The external temperature will rise to 130-135°F during this time, giving you that perfect medium-rare finish.

Using a sharp carving knife, slice the beef tenderloin into 1-inch thick medallions against the grain. The grain direction is visible as subtle lines running through the meat—cutting against it ensures each bite is tender. Arrange the slices on a warm platter and drizzle any remaining herb butter from the pan over the top.

Serve immediately with your favorite sides. The result should be a perfectly smoked, juicy, and tender beef tenderloin with a beautiful crust and layers of herb-infused flavor. Each slice should be rich, moist, and bursting with that perfect balance of smoky and herbal notes.

Wine and beer pairings for this recipe

Bold Red Wines

The rich, smoky depth of your pellet-grilled tenderloin calls for a wine that can stand up to its intensity. I reach for a Cabernet Sauvignon from Napa Valley—its bold tannins and dark fruit notes complement the beef beautifully.

Look for a 2018 or newer vintage like Heitz Cellars or Beaulieu Vineyard for that perfect balance of oak and fruit. The wine’s structure mirrors the tenderloin’s juiciness, making every bite even more satisfying. 🍷

Smoky Syrah

For a wine that echoes the pellet grill’s hickory smoke, a Syrah from the Rhône Valley is my go-to. The peppery, smoky character of wines like Guigal Côte-Rôtie or Chave Hermitage enhances the beef’s natural flavors without overpowering them.

The wine’s boldness pairs perfectly with the herb butter basting, creating a harmonious flavor profile. Trust me, this pairing elevates the meal to restaurant-quality levels.

Crisp Rosé

If you prefer something lighter but still sophisticated, a Provence rosé is a refreshing contrast to the rich beef. The dry, crisp notes of a Château d’Esclans Blanc des Millénaires or Domaine Tempier cut through the smokiness, cleansing your palate between bites.

It’s a great choice for those who want a lighter option without sacrificing elegance. This pairing feels like a breath of fresh air after that first bite. ✨

Beer Pairings

A dark American stout like Founders Kentucky Breakfast Stout brings out the smoky, caramelized notes in the tenderloin. The roasted malt flavors in stouts complement the beef’s richness, while the slight bitterness balances the herb butter’s sweetness.

For a lighter beer option, try a German Pilsner like Paulaner—its crisp, clean profile highlights the tenderloin’s natural flavors without competing. 🍺

Local Craft IPA

If you’re into craft beers, a hoppy IPA from your local brewery can add a fun twist. The citrus and pine notes in beers like Ballast Point Loft or Deschutes Mirror Pond create a refreshing contrast to the smoky, herby beef.

Just be mindful—these beers can be quite bitter, so they’re best enjoyed alongside the tenderloin rather than as a primary pairing. It’s all about balance! 🌟
