Preheat pellet grill smoker to 300F. Trim the pork tenderloin, making sure to remove the silverskin.
Whisk the brown sugar, salt, pepper, garlic powder, onion powder, chili powder, paprika, and ground mustard together in the small bowl.
Pat the pork tenderloins dry with paper towels. Coat all sides with oil followed by the seasoning blend.
Place the pork directly on the grill grates and smoke for 90-120 minutes, or until the internal temperature reads 160F. We like to flip the tenderloins at 45 minutes for an even smoke ring.
Once cooked, remove from smoker and let rest for at least 10 minutes under foil before cutting. This will allow all the juices to redistribute throughout the meat, making it ultra juicy, tender, and delicious!
Slice the pork into ½-inch thick medallions and serve immediately.
Notes
Use your favorite seasoning blend or marinade!
After trimming, pat the pork tenderloin dry, then coat in a neutral oil. Season all sides well.
If using a marinade, let marinate for at least 15 minutes before smoking.
You will have extra spice mix if you use my measurements above, save it to use on other grilled meat.
We use a blend of wood pellets made up of oak, hickory, maple, and cherry. Apple would also be good for this recipe.
