Add all the ingredients to a pot with water. Bring it up to a boil, then turn down the heat and let it simmer for 40 minutes.
Take off heat and allow it to cool down completely. Strain to remove the solids.
Taste and season lightly if needed. Use immediately or store for later.
Notes
You can also make a non vegetarian version of this low sodium broth by adding chicken bones or feet, turkey bones, shrimp tails or even beef or lamb bones- if you have them at hand.
MSG is a great flavor enhancer to add to the broth if you want to up the flavor without adding a lot of sodium. Tomato paste and fish sauce are two other good options to consider!
Avoid adding veggies like cabbage, cauliflower, broccoli, artichokes and bitter greens, as they can turn the broth too bitter.
You can also make a low sodium vegetable broth solely from veggie scraps. Simply transfer your scraps to a Ziploc bag and freeze. Then, when you have enough, add them to a pot and boil. This is an excellent no-waste hack to try.
