This smoked pork loin is tender, juicy, and full of rich, smoky flavor. Seasoned with a simple spice rub and slow-cooked to perfection, it’s an easy yet impressive main dish that’s perfect for cookouts, holidays, or weekend dinners.
Traditionally when I think of pork loin roast I think of Sunday dinner with mashed potatoes, gravy, dinner rolls, and green beans; the works. But it is time to totally rethink that, because a smoked pork loin is unbelievably delicious and should be enjoyed any day of the week!

This smoked pork loin is perfect if you are feeding a crowd or just your family. It takes about 2 1/2 hours to smoke, so it isn’t a huge investment like when you are making Smoked Pork Butt. Plus pork loin is a reasonably priced cut of meat, so it is a great way to elevate it into something new.
If you have never tried smoking pork like this you are in for a treat. It isn’t the same as pulled pork, instead you get the sweet pork flavor in a super tender and juicy cut of meat.

How To Smoke Pork Loin
- Set Up Smoker. Start by preheating your smoker. Get it set up to cook around 225º F. Use your favorite chips, I like apple wood or something mild for pork.
- Prep Pork. Most pork loin roasts you buy at the store has a thin layer of fat on top. You want that there, it will help keep the meat nice and juicy. Just cut diagonal lines criss-crossing on the top of the roast. You want to cut about 1/4 inch deep and end up with diamonds across the top.
- Season. Rub the roast with a tiny bit of olive oil to help the rub to stick. Generously coat the pork with the rub.
- Cook. Once the smoker is ready, place the roast (fat side up) and insert a meat thermometer probe if you have one. Cover and cook for about 2 1/2 hours, until it reaches 145º F. There is no need to wrap a pork loin in foil when smoking, it is a quick cooking cut of meat and not something that you are cooking long enough to need.
- Rest and Serve. Once the pork is cooked let it rest for 5-10 minutes before slicing to serve.
How Long To Smoke Pork Loin
Just like when you are smoking anything, this is subject to change slightly based on your smoker and how evenly it keeps the heat. I find that a 3-4 pound pork loin roast takes about 2 1/2 hours to reach 145º F.
Measuring the temperature of your meat is the best way to know when it is actually done. I use this one from Thermoworks every time we grill or smoke. You can measure the temperature of the meat and the smoker, so it is makes getting it done right super easy with no guess work.
Storage
Store any leftover pork in an airtight container in the fridge for up to 4-5 days. You can reheat in the microwave or heat slices in a hot skillet.
