Slow Cooker Vegetable Broth

Servings: 10 cups
Author: Lisa Le

Ingredients

  • 10 cups 2.5 L water
  • 5-6 carrots cleaned and roughly chopped into 2-3 inch chunks
  • 1 onion washed well, halved (keep peel and cleaned root in tact)
  • 4-5 stalks celery washed well and chopped into 2-3 inch chunks
  • 4-5 cloves garlic cleaned, skin still in tact
  • 3 dried bay leaves
  • 4-5 dried shiitake mushrooms buy a big bag of them at the Chinese market for about $4-5
  • 1 tsp dried oregano
  • 1 tsp dried rosemary
  • 1 tsp dried thyme
  • or sprigs of fresh thyme, rosemary, and oregano tied together or put in an herb bag
  • Optional: any other flavourful harder veggies you have like potato even peeled potato skins, rutabaga, jicama, fennel, parsley, etc. The more veggies there are, the more flavour.

Instructions

  • Place all ingredients in a slow cooker and set on low for 6-8 hours. Pour through a fine-mesh metal sieve (you could also add a cheesecloth to make sure you get out all of the herb bits and other grit). Store in sterilized jars or containers in the fridge for up to 1 week.

Notes

Alternatively, you can do this on the stove for about 1-2 hours: bring ingredients to a boil then cover and lower to a simmer. However, even with a lid, a lot of the liquid will boil off and you'll make less broth than you would in a slow cooker (unless you have a massive pot, which I do not).
