This delicious smoked pork loin recipe requires around 6 hours of smoking time and comes out so tender and juicy. I made slits all over the roast and stuffed them with a garlic and serrano compound butter, then seasoned it with my own pork rub. The end result was an amazingly flavorful pork loin that everyone enjoyed!
We've had a huge pork loin in our freezer for months now, taking up way too much space. So recently we decided to do something with it. We sliced off the fat end to make porkchops for Scott's favorite dinner, pork chops and potatoes.
We were left with a 6 pound roast that we decided to smoke. Let me just say, this smoked pork roast recipe was way better than we expected! It came out so juicy and flavorful!
The combination of brown sugar, kosher salt, black pepper, onion powder, garlic powder, chili powder, smoked paprika, cayenne, rubbed sage, and ground cloves make for one good rub. However, I do believe the serrano and garlic compound butter mixture took it over the top!

🛒 What You Need For This Recipe
🔖 Ingredients & Substitutions
- Pork: Make sure you use the right cut of meat for this recipe. You'll want to purchase a pork lion, not a tenderloin. Pork tenderloin is a much smaller and thinner strip and is a portion of the larger loin muscle that runs along the pig's spine. Since this muscle isn't used for movement, it's very tender, similar to venison backstrap.
- Seasoning: I used my pork rub seasoning, but you can also use your favorite rub. Another great option would be my Santa Maria seasoning.
- Apple juice: For misting the pork roast as it smokes. You can substitute apple cider or apple cider vinegar.
- Compound Butter: To make the compound butter, you'll need fresh garlic, serrano peppers, and unsalted butter. If you're worried about the serranos being too spicy, you can substitute a more mild pepper or just use garlic.
🔪 Helpful Tools
- Smoker/Pellet grill
- Pellets (pecan, mesquite, hickory, cherry)

🐷 How to Smoke A Pork Loin Roast
Step 1: Blend garlic and serranos using a small food processor, then mix into softened butter. Add 1 tablespoon of pork rub and mix to combine.
Pro Tip: Here's the idea that came to me after I made this recipe the hard way... Roll compound butter in plastic wrap and freeze, then slice into small cubes and insert into the slits. It will be much easier to do then working with softened butter!
Step 2: Trim excess fat off of pork loin, if necessary, mine didn't need it. Make sure the pork is at room temperature, then make slits all over the roast and fill them with the compound butter mixture (see pro-tip). Smear any leftover butter all over the pork loin, or use olive oil. Season generously with pork rub.
Pro Tip: At this point, you can wrap the roast in plastic wrap and store it in the fridge or go straight to the smoker!

Step 3: Clean smoker, if needed, then add pellets. Ignite smoker and preheat to 200°F, select super smoke. When smoker is ready, place pork directly on grill grates and insert probe into the thickest part. Set the probe's final temp to 145°F.
Step 4: Spritz pork loin with apple juice, and again every hour. After 5 hours, turn the temperature up to 225°F, if it's done sooner, disregard. Continue to smoke the pork loin until the internal temperature reaches 145°F. Mine took a total of 6 hours.
Step 5: Remove pork loin and place on a baking pan. Tent with foil and rest for 15 minutes before slicing and serving.

🤷🏻♀️ Recipe FAQs
One method of ensuring pork loin remains tender is to inject it with butter before smoking it somewhere between 200-225°F! Another is to spritz it with apple juice as it smokes.
A pork loin should reach an internal temperature of 145°F to ensure that it's fully cooked.
At 225°F, it takes approxmately 45 minutes per pound to smoke a pork loin. This means if you are smoking a 5 pound pork loin, it will take around 4 hours to smoke. This is just an estimate since there are many other factors that can affect this time, such as the pork's beginning temp, outside temperature, and how many times the lid is lifted.
👩🏼🍳 Pro Tips
- My pork loin didn't have much of a fat cap so it didn't need to be trimmed. However, if yours does, just trim off the excess.
- When seasoning the pork loin, sprinkle the rub without touching the meat to avoid cross-contamination. You'll want to save the remaining rub for another use.
- My boneless pork loin weighed 6.25 lbs. If yours is smaller or larger the smoking time may need to be adjusted.
- If the roast is cold, the butter will not stick to it, it will stick to your hands instead. If the butter clumps, no problem! Just smooth it out with a pastry brush after the first hour of smoking, before spraying it with apple juice.
- Don't skip resting the pork loin. This allows the juices to redistribute throughout the roast, resulting in a juicier roast!
