Bone Broth

Have you discovered the delights of bone broth yet? How about concentrated bone broth? The benefit of concentrating broth is that it takes up far less storage space and is portioned out into handy, on-demand squares that readily melt when added to hot water. Before we get to the method of concentrating the broth, first let me share with you my process for making a thick broth that’s easy to concentrate.
Prep Time 1 hour 5 minutes
Cook Time 1 hour 15 minutes
Total Time 2 hours 20 minutes


  • 4 1/2 lb soup bones
  • 1 onion quartered (skins and all)
  • 1 head garlic broken apart, but not peeled
  • 8 cups water
  • 2 T apple-cider vinegar to leach the minerals from the bones


Add all the ingredients to a slow cooker.

  1. Then, I stuff the slow cooker full with 1 lb of mixed greens and stems (any combination of chard, beet greens, kale, spinach, and parsley is fantastic).

  2. Cook it on high for 2 hours (it will take a couple hours for the greens and lid to settle).

  3. After 2 hours, reduce heat to low and cook for 16 more hours (if your slow cooker is like mine, you will need to restart it a couple of times so it doesn’t automatically shut off).

  4. Let it cool on the counter for 2 hours, then remove greens, garlic, onion, and bones.

  5. Chill for at least 6 hours. A layer of fat will float to the top—just scrape it off. Strain solids from broth. After that, your broth is ready to concentrate.

Beef Bone Broth Concentrate

  1. Using the 4 cups of fresh bone broth

  2. Line an 8" glass baking dish with parchment paper; set aside.

  3. In a medium saucepan over medium heat, bring bone broth to a simmer. Continue to simmer for 1 hour, 15 minutes, or until broth has reduced to about 1⁄4 of its original volume and is thick and syrupy. Remove from heat.

  4. Pour reduced broth into prepared baking dish. Refrigerate for 1 hour, or until firm.

  5. 4. Remove from baking dish and cut into 16 squares. Freeze until ready to use. To reconstitute, dissolve 1 square in 1⁄4 cup to 1 cup hot water, depending on how you intend to use it.
