Put a boneless pork loin in your crock pot and partially cover with root beer (any brand not diet). Cook on low 6-8 hours. Drain all the liquid and shred the pork...combine with your favorite BBQ sauce. I like Sweet Baby Rays. Serve on buns. This pulled pork also freezes well so I use most of a full loin.
It’s amazing how wonderful root beer goes with pulled pork!
I’ve posted this recipe for pulled pork with root beer marinade here before - it’s from the allrecipes site....a much more fussy recipe - but boy is it good.
