This is how we make chicken bone broth at home. If you'd like, you can switch out the herbs and vegetables for others you prefer. For example, you could add leeks, celery, or a different type of onion. Roast the vegetables first for added depth of flavor and color.
Be sure to keep the ingredients covered by adding water just to cover through- out the simmering process. The pot can be left overnight to simmer on your stove; however, be sure there is enough liquid in the pot before you go to bed, and keep the flame low. Too much evaporation will result in a burnt batch.
