For this Traeger grilled pork tenderloin, we created our own garlic rosemary pork marinade.
Place minced garlic and chopped rosemary over the pork loin and rub the marinade into the meat.
Place pork in the refrigerator to marinate for 4 hours of up to 1 day.
Once you are ready to grill, begin by setting up and plugging in your electric pellet grill or Traeger. Ensure you have enough wood pellets in the hopper and turn on the Traeger.
Turn the heat up to high (450F on most models, up to 500F on some) and allow it to heat up for 15 minutes.
If using a gas grill, heat the grill to medium or medium-high heat (whatever is around 400F for your grill.)
Once the pork tenderloin has marinated for at least 4 hours, turn the heat down to 400. Place the meat on the grates and close the top.
Cook the meat with the top closed for 6-8 minutes, depending on if you are using a 1-pound, 1.3-pound, or 1.5-pound pork tenderloin.
Flip the meat and allow it to cook for another 6-8 minutes or until the internal temperature reaches 145F.
Allow meat to rest for about 5 minutes before slicing into medallions.
