Notes
Store vegetable broth in the fridge for up to 7 days and in the freezer for up to 3 months.
Instead of the whole vegetables, use 3-4 cups vegetable scraps.
Omit salt for sodium free stock.
This recipe can be doubled in a 6 quart slow cooker and on the stove depending on the size of your pan.
Use any fresh herbs you like. Parsley, rosemary and thyme all work well.
The dried mushrooms add an earthy flavor, but can easily be omitted. You can also use ¼ cup fresh shitake mushrooms, coarsely chopped.
