You can fit 40 hot dogs in a 6qt. cooker. Stand hotdogs on end if you're trying to cram in 40. If not, you can just dump them in. There's no need to add water. The hotdogs will release moisture all on their own,and if the hotdogs hang out in hot water for too long they'll end up splitting on you. Cover, and cook on low for 4 hours, or on high for about 2 hours--check to make sure the ones in the middle are fully hot before serving.
Did you know you can cook a TON of hot dogs in the slow cooker if you just stand them on end?? I got just over 50 in. Then just add a cup of water and turn on low. Hot dogs will be warmed though and ready to eat in about an hour. #partyfood #slowcooker #crockpot #hotdogs
