Pork tenderloin is a leaner cut of pork and won’t produce the same result as a roast or butt. However, you can use a tenderloin for pulled pork with modifications. u003cbr/u003eu003cbr/u003eCook the pork on low for a shorter amount of time, between 4-6 hours. Also, add more liquid to the crock pot to keep the pork from drying out. I recommend 1 - 1 ½ cups of liquid for 3 - 4 lbs of tenderloin. u003cbr/u003eu003cbr/u003eI treat tenderloin the same way I do cooking boneless chicken breasts in the slow cooker. u003cbr/u003eu003cbr/u003eAfter the pork tenderloin is done, remove it from the slow cooker and place it in a bowl to shred. Then spoon in extra liquid from the insert to the shredded meat or toss the pork in barbecue sauce to add moisture.
