Ingredients
You only need a handful of ingredients to make this delicious smoked pork loin. I'm sure you have everything on hand in your pantry already!

- 4-5 pound pork loin roast. Make sure the pork roast is completely thawed before smoking.
- 1 tablespoon olive oil.
- Homemade spice rub.

Pork loin roast spice rub ingredients:
- ½ teaspoon paprika (smoked paprika is the best if you have it)
- ⅛ teaspoon black pepper
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- 1 teaspoon raw sugar (or brown sugar)
- ½ teaspoon sea salt
- ⅛ teaspoon chili powder
- ⅛ teaspoon mustard powder
How to smoke a pork loin roast
- Preheat the smoker. My smoker, which I love, is this Pit Boss 8-in-1 grill and smoker. Set the temperature to 225 degrees F. Make sure you have topped it up with wood pellets of your choice. We like the Competition blend..
- Trim the pork. Very carefully, cut off the layer of fat on the roast. My roast had a very thick layer. Inspect the roast and remove any thick silver skin. Next, score the pork in a diagonal pattern about ¼-inch deep across the top where you just cut the fat off. This helps get the seasoning down into the meat as this is very thick meat.
- Season. Mix the ingredients for the spice rub (paprika, garlic powder, onion powder, black pepper, raw sugar, sea salt, chili powder, and mustard powder) in a small bowl. Apply olive oil to the roast and rub it on evenly (this helps the seasoning stick to the roast). Sprinkle the spice rub over the roast and ensure it covers the entire roast on the top, bottom, and sides. Use your fingers to push the rub into the meat.



How long to smoke pork roast
- Smoke. Place the pork roast directly on the preheated grill and put your thermometer probe in. Close the lid and smoke until the internal temperature of the roast is 145 degrees F. This will take about 2-½ hours.
- Rest and slice. Remove the pork roast from the grill and place it on a plate or platter. Cover the roast with foil for 10-15 minutes so its meat will continue to cook without drying out too much, then slice the roast against the grain, and sit back and let your guests enjoy slicing into this succulent meat! Serve alongside some side dishes like potatoes or vegetables if desired.




Top Tips
- Make sure you cut off the layer of fat on the pork. This cut of meat is so thick we want to get the seasoning down into the meat. That's why it is important to score the meat before you smoke it.
- Check and make sure your wood pellets are all topped up. Check periodically through the cooking process to ensure you don't run out and top up if necessary.
- Most importantly, and I know I keep saying this, but use a temperature probe for your meat. The temperature probe beeps when the meat reaches the appropriate temperature. It is not advisable to keep opening up the smoker's lid to check the meat, so invest in a good meat probe.
Variations
Change the flavor of the pork by changing the ingredients in the spice rub. Have some fun with it! To make it spicy, add cayenne pepper or red pepper flakes.
Storage
Fridge: Leftover smoked pork loin will keep in the fridge in an airtight container for up to 3 days.
Freezer: Leftover smoked pork loin will keep in the freezer for up to 3 months in an airtight container or Ziploc bag. We love using a Foodsaver to freeze our food, it keeps so much longer!
If you have lots of leftovers, slice up the pork roast and place it in a Ziploc bag, and pop it in the freezer for meal prep for school or work lunches.

Equipment
Smoker: Our smoker is an electric Pit Boss smoker 8-1 grill that uses 100% wood pellets as fuel instead of gas or propane.
Wood pellets: We like the Competition Blend, Hickory Blend, and also Applewood Blend.
High-quality temperature probe: This is a must-have item if you own a smoker. We invested in a ThermoPro Wireless Digital Cooking Food Meat Thermometer with Dual Probes as soon as we bought the smoker; it's an absolute necessity!
Frequently Asked Questions (FAQs)
It takes about a ½ hour per pound to cook a pork loin roast to a temperature of 145 degrees F. So, a 5-pound roast takes about 2-½ hours to cook on the smoker. Keep in mind that all smokers cook differently, so use a meat probe to cook properly.
Nope, they are 2 very different cuts of meat. Pork tenderloin is a boneless cut of long and narrow meat and comes from the muscle that runs along the backbone. A pork loin is wider and flatter and is cut from the animal's back.
I would not advise it. Pork tenderloin should be cooked at a high heat rather quickly, and pork loin should be cooked at a low heat to be tender. Both are excellent cooked in a smoker, though.
Preheat your oven to 325 degrees F. Add 1 cup of chicken broth. Lightly brush the pork loin with olive oil, cover with foil, and heat for 25 minutes, or until heated to a temperature of 135 degrees F.
Yes, as long as the internal temperature is 145 degrees F. The pink on the outside is called a smoke ring. A smoke ring is a region of pink-colored meat in the outermost 8-10 millimeters of smoked meat.
We use the Competition Blend, which is a mixture of maple, hickory, and cherry woods. We also like hickory, and applewood is also a very good choice. Cherry and hickory are probably the most popular wood pellets for smoking pork.

Hard to rate this recipe. Mine were a complete failure. After 7 hours I chopped the meat best I could and packaged for soup this winter. After 2.5-3 hours the meat was tough to the point I struggled to slice it and the color wasn’t where I like my pork. So I put it back on the grill. Maybe it was the cut of the loin roast or the size (4.25lbs but was very thick due to bone in the middle), but by 10pm last night we knew we had failed. I won’t buy this cut again, but will try the recipe again.

Hi Barb, I'm sorry to hear that you had a negative experience with this pork loin roast recipe. When I smoke a pork loin roast, it is always boneless and fully cooked in under 3 hours. Perhaps it was a different cut? I would suggest getting a boneless pork loin roast next time, and then you shouldn't have any problems. Thanks for trying out this recipe and providing your review! 🙂
