Bone broth is important when you are doing the keto diet because it contains tons of minerals and provides the electrolytes you need. I make it a point to drink a cup a day with a dab of butter and an extra sprinkle of salt on top. The amount of bone broth you end up with will vary depending on the size of your pressure cooker and how much liquid it can hold.
Makes 15 cups
Preheat the oven to 400°F.
Place all the bones on a large baking sheet and roast for 30 minutes, until dark brown.
Transfer the bones to the pressure cooker. Add the onion, celery, vinegar, rosemary, salt, and enough water to reach the fill line of the cooker. Select the soup button, set the pressure to low, and increase the time setting to 120 minutes.
After cooking, let the cooker naturally release the pressure. Strain the broth into a large bowl and discard the solids. Let the broth cool.
Store in a covered container in the refrigerator for up to 4 days, or in the freezer for up to 4 months. Be sure to leave a little extra room at the top of the container to allow for expansion as the broth freezes.
