  • Electric Pellet Grill
  • ThermPro Wireless Remote Digital Thermometer


  • 4-5 pound pork loin roast
  • 1 tablespoon olive oil
  • 3 teaspoon homemade spice rub below or your favorite spice rub

Homemade Spice Rub

  • ½ teaspoon paprika smoked paprika is best if you have it
  • teaspoon black pepper
  • ½ teaspoon garlic powder
  • ½ tsp onion powder
  • 1 tsp raw sugar or brown sugar
  • ½ teaspoon sea salt
  • ½ teaspoon chili powder
  • teaspoon mustard powder


  • Preheat your smoker to 225 degrees F. Add or top up your wood pellets.
  • Very carefully, with a sharp knife, cut off the layer of fat on the roast. Next, score the pork in a diagonal pattern about ¼-inch deep all 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
  • In a small bowl, mix together the ingredients for the pork spice rub (paprika, garlic powder, onion powder, black pepper, raw sugar, sea salt, chili powder, and mustard powder).
  • Apply olive oil to the pork loin roast and rub it evenly over it. Sprinkle the spice rub over the roast and ensure it covers all parts of the loin, top, bottom, and sides. Use your fingers to push the rub into the meat.
  • Place the pork loin 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 approximately 2.5 hours.
  • Remove the pork loin roast from the grill and place it on a plate. Cover it with foil and let it rest for 10-15 minutes. Slice the roast against the grain and serve to your dinner guests. Enjoy with your favorite side dishes.

I like to slice leftover pork loin into thin slivers of meat and freeze it.  The next time I want to make a stir fry, I just grab the pork out of the freezer for a super quick meal!
