                    One of the best uses for a slow cooker is making vegetable broth. You can control the amount of sodium and the variety of vegetables and seasoning, and the broth can develop a full, rich flavor in the slow-cooker while you busy yourself elsewhere. This recipe depends on browned onion for a hearty flavor and parsnip for a subtle sweetness, but you can experiment with your own veget Ingredients:

Cover, and cook on low for 6 to 10 hours (a longer cooking time will result in a stronger broth). 4. Strain out and discard or compost vegetables, bay leaves and spices. 5.
