Start by saving the washed and clean scraps from your veggies. The carrot peels, celery ends, parsley stems, skin from onions and garlic, ends off garlic and onion etc. You will want a decent amount of onion and garlic for flavour.
Add the scraps into a large ziplock bag, and storing in the freezer. This can be stored up to 3 months. Continue this process until the bag is full.
The best scraps to save are celery, carrots, onions, garlic, parsley and other herbs.
You can save any scraps that are not bitter such as corn cobs, peas, bell peppers, mushrooms, etc. See notes below for a list of veggies to avoid.
When the bag is full, add the scraps into a medium-large pot and cover with water. There should be just enough water for the scraps to float. Add in soy sauce if adding.
Cover, and bring to a boil. Then reduce to a simmer and simmer for at least 45 mins, up to 2 hours.
Season the vegetable stock with salt and pepper. Taste the stock to ensure it is flavourful enough for your liking.
Strain the broth to remove any of the vegetable scraps.
Store in glass jars for up to 4 days in the fridge, or up to 3 months in the freezer. Enjoy!
