Smoked Chicken Tenderloin Recipe: Wood-Fired Flavor in Your Backyard

I’ve been smoking chicken for years, and tenderloins might be my favorite cut for the smoker. There’s something magical about how the wood fire transforms these lean pieces into juicy, flavor-packed bites.

The secret is low and slow—225°F for about 2 hours gives them time to absorb that smoky flavor without drying out. I use a simple dry rub that lets the natural taste shine through.

What comes out is tender chicken with a perfect mahogany crust, infused with your choice of wood smoke. The meat pulls apart easily but still holds its shape on your plate.

Serve with cornbread and coleslaw for a backyard meal that tastes like it came from a pitmaster. Here’s how to do it right.

Ingredients for Smoked Chicken Tenderloin

Lean, smoky, and packed with flavor. Just a few ingredients for tender perfection.

The chicken is the star here. Tenderloins are naturally lean, so look for plump, moist pieces—avoid anything gray or dry. Most grocery stores carry them pre-packaged, but butcher shops often have fresher options. I grab mine from Whole Foods when I want organic, or Costco for bulk savings. The key is even thickness so everything smokes uniformly.

No brown sugar? Honey or maple syrup works in a pinch (skip if avoiding sugar entirely). Swap hickory for apple or cherry wood for milder smoke. If you’re out of paprika, chili powder at half the amount adds depth. The vinegar can be white or red wine—whatever’s in your pantry. The mustard is mostly for binding, so Dijon works too (just use less).

Rub keeps in an airtight container for 2 weeks. Chicken tenderloins freeze beautifully for 3 months—just thaw overnight before smoking. Leftovers? Shred for sandwiches (they’ll taste even better the next day).

Step-by-Step Instructions for Smoked Chicken Tenderloin

Here’s my tested method for achieving fall-off-the-bone tenderness with deep smoky flavor.

Step 1: Create the Flavor-Packed Rub

In a medium bowl, combine the 0.25 cup brown sugar, 2 tbsp paprika, 1 tbsp garlic powder, 1 tbsp onion powder, 1 tbsp salt, 1 tsp black pepper, and 0.5 tsp cayenne pepper. I use my hands to really mix everything together, breaking up any clumps in the brown sugar.

The sugar will caramelize during smoking, creating a beautiful crust. This rub makes enough to generously coat the 2 lb chicken tenderloins, and you’ll want to use it all for maximum flavor. The cayenne adds subtle heat that balances the sweetness.

Step 2: Prep and Season the Chicken

Pat the chicken tenderloins completely dry with paper towels. This ensures the rub adheres properly. Then brush each piece lightly with the 1 tbsp yellow mustard—this acts as a binder for the dry rub and adds a subtle tang without overpowering.

Rub the spice mixture all over the chicken, pressing firmly so it sticks. Arrange the coated tenderloins on a plate, cover with plastic wrap, and let them sit at room temperature for 30 minutes while you prepare the smoker. The mustard and rub combination creates that signature bark we’re after.

Step 3: Set Up the Smoker with Wood Chips

Soak the 2 cups hickory wood chips in water for 30 minutes, then drain. Fill your smoker’s water pan to help maintain moisture during the long cook. Preheat your smoker to 225°F using indirect heat.

When ready, add the soaked wood chips to the smoker box or directly onto the coals. You want to see that perfect thin blue smoke before adding the chicken. Too much smoke or white smoke means the wood isn’t burning cleanly, which can make the chicken taste bitter.

Step 4: Smoke to Perfect Tenderness

Place the chicken tenderloins directly on the smoker grates, leaving space between each piece for smoke circulation. Smoke at 225°F for 2 to 2.5 hours, or until the internal temperature reaches 165°F.

About halfway through, I like to baste the chicken with a mixture of the 2 tbsp olive oil and 1 tbsp apple cider vinegar. This keeps the meat moist and adds another layer of flavor. The chicken is done when it’s deep golden brown and the juices run clear.

Step 5: Rest and Serve

Remove the chicken from the smoker and let it rest under loosely tented foil for 10 minutes. This allows the juices to redistribute throughout the meat, ensuring every bite is tender and flavorful.

Slice the tenderloins against the grain and serve immediately. The meat should pull apart easily with a fork and have that beautiful smoke ring just beneath the surface. The combination of the sweet-spicy rub and smoky hickory flavor makes this dish unforgettable.

Troubleshooting This Recipe

Uneven Cooking

If some pieces finish before others, it’s likely because they’re not uniform in thickness. I always pound thicker ends gently with a meat mallet to even them out. Aim for 1-inch thickness across all tenderloins for consistent cooking at 225°F. 💡

Dry Chicken

This usually happens when the smoker temperature runs too high or you skip the resting step. Keep your smoker between 220-230°F and always rest the chicken for 10 minutes after smoking. Basting with olive oil and vinegar every hour helps maintain moisture.

Bitter Smoke Flavor

White or thick smoke creates bitterness. Only smoke when you see thin blue smoke. Soak your hickory wood chips for 30 minutes and use a water pan. If your wood chips are old or dusty, they can also cause bitter flavors.

Rub Won’t Stick

The chicken must be completely dry before applying the rub. I use paper towels to pat them thoroughly. The yellow mustard binder is crucial—brush it on lightly but evenly. Don’t apply rub to wet chicken, as it’ll just slide off.

Stall in Temperature

Chicken can stall around 150-160°F. Be patient and maintain 225°F. If stalled too long, wrap in foil with 2 tbsp apple juice to push through. This happens as moisture evaporates from the surface.

Weak Smoke Flavor

For stronger smoke, use 3 cups wood chips instead of 2 cups. Add fresh chips every 45 minutes. Hickory gives bold flavor, but apple or cherry wood can be more subtle. Don’t oversmoke—more than 3 hours can make it bitter.
