An inexpensive cut of meat, pork loin tastes best when it is grilled. Grilling a pork loin locks in the juices and gives the meat a nice, smoky flavor. When it comes to grilling meat, the pork loin is a great choice because of its mild flavor. The mild flavor of the pork loin makes it better than most other types of meat cooked on the grill.


However, just like with any other type of meat, there are a few don’ts when cooking a pork loin on a gas grill. The first of them is making sure the pork loin is not overcooked. If this happens, then the pork loin will dry out and you won’t get the mild flavor of the meat.


Another thing to avoid when cooking pork loin on a gas grill is making sure you don’t cook it on high-heat or temperature. If you cook the pork loin on high heat, then it will dry before the inside is even cooked. This is because the pork loin is a large chunk of meat. Now that you know the things to avoid when grilling a pork loin, you are ready to find how to grill a pork loin.


The Best Way to Grill a Pork Loin

Indirect cooking is the most common and the most effective way to grill pork loin. What does indirect cooking involve? Placing the meat on the side of grill which is opposite to the heat source. The idea is to allow the pork loin to more slowly come to temperature by creating a gentler heat around it. If you decide to position the pork loin on the same side as the heat source, then the meat’s exterior is likely to blacken, become dry, or even burn before the inside is cooked or safe to eat.

However, the duration for grilling a pork loin could be more or less, depending on the heat on your gas grill and the size of meat you are grilling.

When it comes to grilling a pork loin, you must know one hack. The hack that we’re referring to is the use of a double probe digital thermometer. This is quite literally the best thing to have when grilling a pork loin or any other meat for that matter.


By attaching one probe of the digital thermometer to the pork loin’s center and the other on the grill grate, you can find out the internal temperature of the meat and monitor the grill temperature at the same time. This will help you ensure that your pork loin does not dry, burn, or blacken before it is cooked from the inside. So, if you’re looking to grill a flavorful and nicely-cooked pork loin, get yourself a double probe digital thermometer. This is one of the best advice that we can give you.
