In order to keep this beef bone broth recipe as cheap as possible, instead of using full carrots, celery, and onions, try saving your scraps from previous meals. Every time I cut an onion or other vegetables I toss the scraps in a ziplock bag in the freezer to use in our broth recipes. This not only saves money but gives use to all of the pieces of the vegetable. I like to wait until I have at least one large freezer bag so I can make a big batch.
