Roasted chicken bones
Optional Veggies: Onion, Carrots, Celery, Leeks
Salt & pepper
Add the chicken bones and any veggies to a crockpot, season well with salt and pepper.
Fill the Crockpot to the brim with water, and set the Crockpot to "Low" for 24 hours.
Remove the crock from the Crockpot base, and let it cool slightly (1 - 2 hours).
Remove bones and veggies from Crockpot and discard. Ladle the broth into storage containers. Freeze or use within 7 days.
I keep a container of chicken bones (from roasted chickens or store-bought Rotisserie chickens) and veggie scraps in my freezer. When it fills up, I make a batch of broth.
To store broth I'm going to use within a week, I use leftover yogurt containers. For freezing, my favorite containers are 4-cup Stasher reusable silicone bags (they can be boiled to defrost quickly).
