I’ve made recipes in the slow cooker before that yield broth, like this one. But, I had not seen one where you could take already cooked chicken and turn it into an easy broth. For awhile, I was buying rotisserie chickens from the store and eating them throughout the week for lunch. It was easy and cheap. Well, now I was able to take those carcasses I saved (just in case) and use them for a stock. The original recipe says you need 3-4 chicken carcasses, but I found 2 was plenty. Maybe my chickens run large? Basically, once I filled one of my gallon-sized freezer bags with the bones, I was ready to go.
