Pork tenderloin is an exceptionally lean cut that benefits from added flavor — and smoking is a perfect solution. This method is simple and mostly hands-off when you use a remote probe thermometer: set the probe, monitor the readout, and let the smoker do the work.
A short dry brine with kosher salt, a gentle smoke with apple or cherry wood, and an optional quick sear at the end transform an inexpensive tenderloin into a tender, flavorful centerpiece. From start to finish expect roughly three hours, most of which is passive time while the meat cooks and rests.
Smoked tenderloins are great for serving a crowd—sliced thin they disappear fast. The smoke enhances the mild pork flavor without overpowering it. Pair the slices with simple roasted vegetables, mashed potatoes, or grilled greens for an easy, satisfying meal.
Key Temperatures & Info
- Smoker Temp: 225–250°F
- Target Internal Temp: 140°F (remove from heat; carryover will bring it to around 145°F)
- Cook Time: About 1 to 1½ hours (varies by meat size and smoker)
- Wood: Apple or cherry
Top Tips for Success
- Don’t overcook. Tenderloin is very lean and dries out quickly. Pull the meat at 140°F for a juicy medium; adjust slightly higher if you prefer well done.
- Use a remote probe thermometer. A probe lets you monitor internal temperature without opening the smoker and losing heat and smoke.
- Shop smart. Buying tenderloins in multi-packs is often the best value if you’re feeding a group or prepping meals ahead.
- Always rest the meat. Tent the cooked tenderloins with foil and rest at least 10 minutes so juices redistribute before slicing.
How Long to Smoke a Pork Tenderloin
At 225°F, a pork tenderloin usually takes about 1 to 1½ hours to reach 140°F internal temperature. Exact cook time depends on the tenderloin’s starting temperature, thickness, and your smoker’s stability. Always cook to temperature rather than time for consistent results.
An instant-read thermometer is helpful for quick checks. For truly hands-off monitoring, use a remote probe that tracks both meat and smoker temperatures so you don’t need to open the lid during the cook.
Pro tip: Let the tenderloin sit at room temperature for 20–30 minutes before placing it in the smoker to promote even cooking.
Brine & Seasoning
Brining helps lean proteins retain moisture and adds flavor. You can use a dry brine or a wet brine. A dry brine (salting ahead) is simple and effective: heavily salt the tenderloins and refrigerate them uncovered on a wire rack for 2–4 hours. This both seasons the meat and improves moisture retention.
A wet brine adds moisture as well as seasoning. A basic wet brine is water, salt, and sugar; you can boost it with crushed garlic, thyme, rosemary, peppercorns, chili powder, or paprika for extra flavor.
After brining, apply a light coat of neutral oil and rub the outside with your favorite dry rub to develop color and a seasoned crust during smoking.
Pork Loin vs Pork Tenderloin
These two cuts are different in size, texture, and best cooking methods. Pork loin is larger and firmer, suited for roasting, slicing into chops, or smoking at lower temperatures for longer times. Pork tenderloin is smaller, more tender, and benefits from quicker cooking methods like grilling, skillet searing, sous-vide, or a short, hot smoke.
Serving Suggestions
Smoked pork tenderloin pairs well with creamy mashed potatoes, green beans, or grilled broccolini. It’s also excellent sliced for sliders with a little BBQ sauce or chopped into tacos. Leftovers reheat well and make flavorful sandwiches or salads.
Smoked Pork Tenderloin
Ingredients
- 2 pork tenderloins (about 1.5 lbs each)
- 1 1/2 tbsp kosher salt
- 2 tbsp dry rub
- 1 tbsp canola or vegetable oil
- apple or cherry wood chips
Instructions
-
Trim the pork. Remove any silverskin with a sharp knife so the texture is more tender after cooking.
-
Dry brine (2–4 hours). Generously season with kosher salt, place on a wire rack over a sheet pan, and refrigerate uncovered to let the salt penetrate and improve moisture retention.
-
Preheat the smoker. Set up for indirect heat and bring to 225°F. Add apple or cherry wood chips for a mild, complementary smoke. Remove the pork from the fridge while the smoker comes to temperature.
-
Apply oil and rub. Lightly coat the tenderloins with oil, then apply the dry rub evenly.
-
Smoke to temperature. Smoke until the internal temperature reaches 140°F — typically 1 to 1½ hours. Remove the meat and allow carryover cooking to reach about 145°F while resting.
-
Optional sear. For added crust, pull the tenderloins at roughly 135°F and sear 1–2 minutes per side on a hot grill or skillet, finishing at 140°F.
-
Rest and slice. Transfer to a cutting board, tent with foil, and rest 10 minutes or longer before slicing crosswise and serving.
Notes
- Use a reliable meat thermometer to verify doneness and avoid overcooking.
- Rest the meat to retain juices before slicing.
- Choose mild fruit woods like apple or cherry to complement pork without overpowering it.
- Searing is optional but adds texture and caramelized flavor.
