How Long Do You Smoke A Pork Loin Roast Per Pound?

Allocate half an hour per pound of pork. So, if you have a 5-pound pork loin, you’ll want to smoke it for 2.5 hours. 

You should use a meat thermometer to measure the internal temperature of the pork loin. Smoke it until it reaches a temperature of about 145 degrees. The optimal temperature for pulled pork is 200°F – 204°F due to the connective tissue. Then, let it rest for 10 to 15 minutes before serving.

Pork Tenderloin vs. Pork Loin

Smoked boneless pork loin is different from smoked pork tenderloin. While both of them are great to smoke because of their high-fat content, they’re not the same, and they cannot be cooked the same way. 

Tenderloin is a long and thin cut of meat, whereas pork loin is larger and flatter. Tenderloin is always boneless, but pork loin can be purchased with or without the bone.

(If the pork loin has intact bone, you can cut it into smaller pieces, and they’ll form pork chops.) We won’t teach you how to smoke pork tenderloin in this article, but here is smoked tenderloin recipe.

This recipe is great because it’s super easy to follow, and you can cook it with an ordinary smoker. If you don’t have one of those, don’t worry—you can easily make a DIY smoker.

How to Smoke a Pork Loin Roast

These are the steps for my world-famous smoked pork loin recipe. I thought it would be good to include it here for you,

  1. You’ll want to begin by preheating your smoker or DIY smoker.
    The smoker temperature should read around 225-250 degrees. 
  2. While the smoker is heating up, use this time to prep and tenderize your pork meat. Cut away any extra fat from pork loin. This additional fat would include anything that is over a quarter inch.
  3. Next, you’ll want to grab a small, sharp knife and diagonally make cuts over the fatty layer of the pork. This is how the smoky flavor and other rubs, marinades, and seasoning will penetrate the piece of meat. (This will also ensure that the entire pork’s fat layer becomes crispy, just like the crispy Asian pork served in Asian restaurants.)
  4. You’ll then want to spread oil all over the pork and cover it with your favorite rub.
  5. Then you need to place it into your preheated smoker or the grill grates of your DIY smoker.
  6. Cover the lid and ensure that the temperature stays around 140-145 degrees Fahrenheit. At 220°F, you’ll want to cook the pork loin for 2-3 hours. If you don’t have a thermometer, use one of the methods to check if the pork is done.
  7. When it’s done, you have to leave it to rest. So you’ll want to make a cover with aluminum foil and place the smoked pork loin under it.
  8. After that, it’s ready to serve!

    Note: Pork loin last 3-5 days in the fridge, after that you should dispose of it.

Want to try it stuffed? The Italians do a stuffed pork loin called porchetta.

This pork loin has a stuffing of Parmesan, breadcrumbs, and lots of herbs. This is placed on the pork loin, then the whole smoked loin roast is then rolled and smoked or roasted.

Or maybe you want the Mediterranean stuffed pork loin? This pork loin is stuffed with Greek ingredients like feta, spinach, and olives then wrapped in bacon.
