This is how to make vegetable stock from onion skins, celery tops, carrot peels and garlic scraps simmered with herbs, peppercorns and a bay leaf. Save scraps in a freezer bag, and when it is full, you have stock for soups, grains and sauces.
Pour water on top, making sure everything is covered by 2 inches water. Leaving an inch or two below the top of the pot so it doesn’t boil over.
Cover, bring to a boil at high heat, and then reduce to a rolling simmer for 2+ hours or until vegetables are so soft they are falling apart.
Strain the stock through a fine-mesh strainer and discard scraps.
Pour broth into air-tight containers, like quart-size mason jars.
Notes
To make this in a crockpot, add all ingredients to the crockpot. Cover with water by 2 inches then cover and set to low for 8-10 hours. Follow steps 2-3 above.
The nutritional info is based on my sample recipe; yours will vary depending on the types of vegetables you use.
I just make a batch of stock whenever I get a full-gallon bag of veggies. No need to thaw them in advance!
Don't be afraid to use onion shells, garlic skins, really ALL the scraps you have.
Feel free to boost your broth with fresh turmeric, fresh ginger, or a tbsp of apple cider vinegar.
Refrigerate broth for up to 5 days. You can also freeze the broth for up to 3 months in freezer-safe containers.
