The closest substitute for chicken broth is a chicken bullion cube and boiling water. A bullion cube and 1 cup of water can be substituted for each cup of chicken broth needed in a recipe. Vegetable broth is another easy one-to-one substitute that is meat-free.
When bullion or vegetable broth are not an option, 1 tablespoon of butter or olive oil added to 1 cup of water can be used in the place of chicken broth. Alternatively, 1 cup of white wine can be used as a substitute as well. While these all have a different taste, they can all provide a flavorful base for soups, stews and other dishes.
