When shopping for vegetable broth, I look for one dark in colour to make rich brown gravy.
This gravy is chunky, but if you prefer a smooth gravy, you can blend the prepared gravy using an immersion or standing blender as desired. This will make the gravy thicker so you can add more vegetable broth as needed to thin.
Make Ahead: If preparing the easy vegan mushroom gravy ahead of time, allow it to cool completely before storing in an air-tight container in the fridge for up to 3 days. Reheat on the stove by bringing it back to a gentle simmer, adding a splash of vegetable broth or water to thin, if needed.
