Compost Veggie Stock

compost_stock_bagSeveral months ago, I started a veggie stock “compost” bag in the freezer. Instead of throwing the ends of an onion or carrot into the compost bin, I put them into the bag in the freezer. This weekend, I made the most delicious stock from the bits and ends that might have otherwise gone to waste. It was super simple to throw together and is the most delicious way to put veggie waste to use.

Compost Vegetable Stock

A gallon-size ziplock bag of frozen vegetable bits
1-2 cloves of fresh garlic, peeled and slightly smashed
a sprig or two of thyme
½ teaspoon salt
~ 8 cups of water

Combine all the ingredients into a large stockpot. Bring to a boil, then lower the heat. Simmer for at least an hour. Remove from the heat and cool completely before straining and transferring to clean jars or containers for storage in the freezer.

Makes about 2 quarts of stock (with head room for expansion when they freeze – about 7 cups)

Coincidentally, I discovered that King County recently launched a campaign to educate people on ways to reduce their food waste. They teamed up with PCC and made a couple of videos with simple food waste reduction tips and tricks. I am totally making an “Eat Now” box for my fridge!

    Yes! The freezer stockpile for broth-making is one of the most useful tips ever. I’ve been doing it for…five years? and our resulting broth has gone into everything from risotto to enchiladas. BEST PLAN.

    Oooooh – I love this idea! I’m gonna do this!
    And don’t you just love our city (well – your city. Mine by commute.) for being all creative about food waste. I dig the left coast just so very much.
    I do this same thing, kinda, but instead of veggies, I throw rabbit, chicken and quail spines in the bag to keep and later put in the crockpot. Which sounds gross, but it’s the best bone broth or meat stock in the world!!

    Even with that much headspace in my jars, they are cracking. I just bought two plastic freezer tubs for stock. Sigh. Maybe I should be freezing stock in zip-lock baggies?
