- Baking sheet(s) and parchment paper
- Slow cooker
- Glass mason jars or other glass jars you have saved
- Large bowl
- Small strainer
- 4-6 lbs of meaty beef bones (include marrow bones and knuckles if possible), preferrably grass-fed
- 2 tbs of apple cider vinegar (raw, unfiltered) – Filsinger’s or Bragg’s make excellent ACV
- Enough filtered water to fill the slow cooker
- Preheat oven to 400 F
- Put parchment paper on one or two baking sheets and spread bones out evenly
- Roast in the oven for 30 min, turning once halfway through
- Place bones in slow cooker and cover with filtered water (leaving a bit of space before the lid)
- Add 2 tbsp of apple cider vinegar and let sit for an hour (this helps to draw the minerals from the bones into the water)
- Turn the slow cooker onto high and bring to a boil, then turn it to low
- Let it simmer for 24-72 hours (check periodically and add more filtered water if it is getting lower)
- Turn off the slow cooker and let the broth sit to cool down
Transferring the broth into the jars:
I usually wait about an hour before transferring the broth into the jars.
Take your large bowl and put a strainer on top. Using the ladle, spoon the broth through the strainer into the bowl. Remove the strainer and pour the broth into the glass jars. You will ned to strain in batches. Put the jars in the refrigerator and leave over night.
The next day, skim off the layer of fat. First, use a knife to loosen the edges and you should be able to pull the fat out in one piece, although sometimes it does break apart. It’s no biggie if you have a bit of fat floating around in there (it broke apart a bit in this case – see below, whoops). If you are using grass-fed organic beef bones, you may wish to keep the fat for cooking. Otherwise, dispose of the fat because toxins are fat soluble.
You can keep about 5 days worth in the fridge and freeze the rest. Aim to drink 1/2 to 1 cup of broth with each meal for maximum digestive healing benefit. It’s such an easy and cost effective way to obtain the minerals and amino acids that are crucial for healing leaky gut. Bone broth is also an excellent natural joint rebuilding formula!
Some people choose to add spices, herbs and vegetables to their bone broth and that’s cool, but I like to keep it simple because I make it weekly and it tastes rich and satisfying as is. If you’re looking for something more like a soup, here’s a good recipe for chicken broth (with some veggies and spices) from The Paleo Mom.
