For the best results, choose a high-quality beef tenderloin from a trusted butcher or Whole Foods. Look for center-cut with even thickness. The spice blend is where you can get creative—add your favorite herbs or adjust the chili powder to your heat level. I like to use Penzeys for their spice quality.

No garlic powder? Use minced fresh garlic (about 2 cloves) instead. For onion powder, you can substitute with finely minced shallots. If you prefer a different type of sugar, coconut sugar works well too. The key is to let the meat sit with the dry rub for at least an hour before smoking.

This dish reheats beautifully—just wrap tightly in foil and reheat at 250°F until warmed through. Keeps in the fridge for up to 3 days. The spice blend can be made ahead and stored in an airtight container for up to 6 months.

Step-by-Step Instructions for Smoked Beef Tenderloin

Here’s the method that delivers tender, flavorful perfection every time you smoke beef tenderloin.

Step 1: Prepare the Beef Tenderloin

Start by trimming any excess fat from the 1.5 lb Beef Tenderloin if needed. I like to leave a thin layer for moisture retention during the long cook. Next, mix together the dry rub ingredients: 2 tbsp Kosher Salt, 1 tbsp Black Pepper, 1 tbsp Paprika, 1 tsp Garlic Powder, 1 tsp Onion Powder, 1 tbsp Brown Sugar, 1 tsp Chili Powder, and 0.5 tsp Cumin. Apply this rub evenly to all surfaces of the tenderloin, pressing gently to ensure it adheres. Let the meat sit at room temperature for 1 hour before smoking to allow the rub to penetrate.

While the beef is tempering, prepare your smoker by preheating it to 225-250°F using your preferred type of wood chips – I recommend hickory for its strong, smoky flavor that complements beef beautifully. Once the smoker is ready, add 1 cup Wood Chips to generate plenty of smoke.

Step 2: Smoke the Tenderloin

Place the prepared beef tenderloin in the smoker, fat side up if it has a fat cap. Close the lid and smoke undisturbed for 2-2.5 hours until the internal temperature reaches 115-120°F. During this time, you’ll start to see the rub forming a crust on the meat – this is where the magic happens. Every 30 minutes, spritz the tenderloin with 0.25 cup Apple Cider Vinegar to keep it moist and enhance the flavor.

Monitor the smoker temperature closely to maintain consistent heat. If you notice the temperature dropping, adjust your vents or add more charcoal as needed. The slow cooking process breaks down the connective tissues in the meat, making it tender and juicy.

Step 3: Finish and Rest

Once the tenderloin reaches the desired internal temperature, remove it from the smoker and wrap it tightly in foil. Let it rest for 15-20 minutes while it reaches the final internal temperature of 130-135°F for medium-rare. This resting period allows the juices to redistribute throughout the meat, ensuring every slice is moist and flavorful.

After resting, unwrap the tenderloin and slice it against the grain into ½-inch thick slices. Serve immediately while still warm, enjoying the tender texture and rich, smoky flavor that comes from the perfect combination of the dry rub and low-and-slow smoking.

Pro Cooking Tips for This Dish

Temperature Control Mastery

The key to perfect smoked beef tenderloin is maintaining a consistent smoker temperature between 225-250°F. I use a dual-probe thermometer to monitor both the smoker and internal meat temperature. This ensures we stay within the ideal temperature range for tender, juicy results.

Meat Preparation Essentials

Start by trimming any excess fat from your 1.5 lb beef tenderloin, leaving a thin layer for moisture retention. The dry rub mixture should be applied evenly to all surfaces – press gently to ensure it adheres. Let the meat sit at room temperature for 1 hour before smoking to allow the flavors to penetrate.

Smoking Technique Tips

Place the tenderloin in the smoker fat side up and close the lid. Smoke undisturbed for 2-2.5 hours until the internal temperature reaches 115-120°F. Every 30 minutes, spritz with ¼ cup apple cider vinegar to maintain moisture and enhance flavor. Monitor your smoker temperature closely and adjust vents or add charcoal as needed.

The Importance of Resting

Once the tenderloin reaches 115-120°F internally, wrap it tightly in foil and let it rest for 15-20 minutes. This resting period allows the juices to redistribute, resulting in tender, juicy slices. The final internal temperature should reach 130-135°F for medium-rare during this resting time.

Slicing for Maximum Tenderness

After resting, unwrap the tenderloin and slice against the grain into ½-inch thick slices. Cutting against the grain ensures maximum tenderness in every bite. I like to serve immediately while still warm to enjoy the full depth of flavors from the dry rub and smoking process.

Equipment Matters

I recommend using a quality smoker with temperature control and a dual-probe thermometer for monitoring both smoker and meat temperatures. For wood chips, hickory provides a strong, smoky flavor that complements beef beautifully. The right equipment makes all the difference in achieving that perfect smoked tenderloin. 🔥
