The beef makes all the difference here. Center-cut tenderloin from Costco or Whole Foods is your best bet—look for bright red color and good marbling. If you can’t find center-cut, ask the butcher to trim it for you. The wood chips? Hickory or cherry from Traeger or Traeger Grills give that authentic BBQ flavor. I always buy extra wood chips—they burn fast and you don’t want to run out mid-smoke. Fresh herbs are worth the extra minute to chop, but dried thyme at half the amount works in a pinch.

No hickory chips? Pecan or apple wood both work beautifully. The mustard powder adds depth without overpowering—skip it if you prefer a sweeter rub. For the salt, Diamond Crystal kosher is my go-to because it clumps nicely for easy measuring. If you’re using pre-mixed rubs, Montana Steakhouse or Stubb’s are solid choices, but homemade always tastes better. The olive oil should be something you’d drizzle on bread—nothing fancy, just good quality. And trust me on the cold butter for the sear—room temperature butter turns into a greasy mess.

Store your wood chips in a sealed container in the fridge to keep them fresh. The tenderloin can sit in the fridge for 2-3 days before smoking, but plan ahead—it needs time to come to room temperature. Once smoked, it reheats beautifully—350°F for 15 minutes wrapped in foil. I always make extra rub to keep on hand for future projects. The fresh herbs? Use them within 3 days or freeze them in olive oil for up to 3 months

Step-by-step instructions for smoked tenderloin with crispy bark

Here’s the method that delivers melt-in-your-mouth tenderness with that coveted smoky crust.

In a small bowl, combine the 2 tablespoons coarse kosher salt, 1½ tablespoons freshly ground black pepper, 1 tablespoon smoked paprika, 1 tablespoon garlic powder, 1 tablespoon onion powder, 1 tablespoon brown sugar, and 1 teaspoon mustard powder. Mix thoroughly until evenly distributed – this dry rub will create that perfect balance of smoky depth and subtle sweetness.

Pat the 4 lb beef tenderloin completely dry with paper towels, removing any remaining moisture from the surface. This step is crucial for developing that crispy bark later. Apply the rub generously all over the tenderloin, pressing it firmly into the meat so it adheres well. Let it sit at room temperature for 30 minutes while you prepare your smoker – this allows the rub to penetrate and the meat to come to an even temperature.

Soak the 1 package hickory wood chips in water for 30 minutes before using. This prevents them from burning too quickly and gives you more consistent smoke. Set your smoker to 225°F and allow it to preheat for 15 minutes before adding the soaked wood chips. You want to see clean, blue smoke – not thick white smoke – which indicates proper combustion.

Place the tenderloin in the smoker on the grill grate, fat side up if there’s any remaining fat cap. The reason we use this low temperature is to cook the meat slowly and evenly, allowing the smoke to penetrate deeply without drying out the center. Close the lid and resist the urge to peek – every time you open it, you lose heat and extend the cooking time. Let it smoke undisturbed for 2 hours before checking the internal temperature.

After 2 hours, check the internal temperature using a meat thermometer. It should read between 145-150°F – this is when you’ll want to add the 4 tablespoons unsalted butter and 2 tablespoons olive oil to the smoker. Use tongs to carefully lift the tenderloin and pour the melted butter and olive oil over it, basting all sides. This creates that beautiful bark while keeping the meat moist.

Return the tenderloin to the smoker and continue cooking until the internal temperature reaches 155°F. This usually takes another 1-1½ hours, but timing depends on your smoker’s consistency. The bark should be deep mahogany color and crispy to the touch. Here’s the thing – don’t rush this step. The bark develops gradually, and rushing will result in a tough exterior while the inside remains undercooked.

Once the tenderloin reaches 155°F, remove it from the smoker and transfer to a cutting board. Let it rest for 15-20 minutes before slicing. This resting period is absolutely critical – it allows the juices to redistribute throughout the meat, ensuring each slice remains juicy and tender. During this time, prepare your finishing herbs by combining the ½ cup fresh rosemary and ½ cup fresh thyme in a small bowl.

After resting, slice the tenderloin against the grain into ½-inch thick slices. Arrange the slices on a serving platter and sprinkle generously with the chopped rosemary and thyme. The combination of these fresh herbs adds a bright, aromatic finish that complements the smoky flavors perfectly. Serve immediately while still warm for the ultimate experience – each bite should deliver that perfect balance of tender, juicy meat with a crispy, smoky crust.
