Pork loin vs. Pork Tenderloin

The pork loin and the pork tenderloin are not the same cut, and they are very different from one another. The pork tenderloin is smaller and thinner, while the pork loin is thick enough to be sliced into steaks.

There is, however, a significant distinction based on preparation methods. While pork loin benefits from long roasting or grilling, pork tenderloin is best when cooked rapidly over moderate heat. We have an excellent Air-Fryer Pork Tenderloin recipe here.

Is Pork Loin a Good Substitute for Pork Tenderloin?

Although both pork slices are rather lean, they should not be used interchangeably in recipes because to their distinct sizes and forms.

Smoking a Pork Loin Roast

There are several reasons why pork loins are perfect for smoking. The first is their accessibility; they are a cheap cut found in most supermarkets and butcher shops. In the United States, loins are often sold as either half loins (weighing around 4–5 pounds) or full loins (weighing about 8 pounds).

This recipe for smoked pork loin roast works well with any size of loin you have on hand. In general, you should plan on serving a half pound of roast per person for dinner and a third of a pound during a party.

For tender, juicy results, smoke the pork loin at 225 degrees Fahrenheit (107 degrees Celsius) for 2 1/2 to 3 hours or until the internal temperature hits 145 degrees Fahrenheit (63 degrees Celsius).

For a well-cooked roast, cook it until the thermometer registers 145 degrees Fahrenheit (63 degrees Celsius), then remove it from the smoker and let it rest, covered with foil, for 10 to 20 minutes.

This will allow the roast to reabsorb its juices and stay warm for serving. Pork chops, pork roasts, pork loins, and pork tenderloin should be cooked to an internal temperature of 145 degrees Fahrenheit (63 degrees Celsius) and rested for three minutes, as recommended by the United States Department of Agriculture.

While smoking a roast, it’s more necessary to cook it to a certain internal temperature than for a certain period. Smoking times will differ from individual to individual and smoker to smoker due to various factors, including but not limited to climate, smoking style, and cut. I use a wireless thermometer to check on my smoked pork loins periodically. 

This recipe may use charcoal, gas, pellet, or electric smoker. Indirect heat from a gas or charcoal grill will also work.

In the absence of a permanent water reservoir, a disposable aluminum foil pan filled with water can be placed beneath the roast to keep it moist during smoking. Water pans in a smoker is essential for maintaining an even temperature and tender meat.
