1Wash and season leg quarters lightly (because BBQ sauce will be salty). Place in crockpot with largest legs at the bottom; smaller legs at the top. Do not add water (I sprinkle a little minced onion on top of mine). Place top on crockpot and cook 5 hours on HIGH. Pour off broth. Cover chicken with barbecue sauce and cook on LOW about 15 more minutes. Turn off crockpot.
