Having many allergies I am an avid ingredient label reader and as such I have noticed that there aren't many broth options out there that don't have sugar or gluten added to them. A lot of the ingredients added to store bought broths (yes, even the "healthy"-read expensive-ones) really have no place being there. Additionally, making your own healthful and flavorful broth is so incredibly easy.
When I first heard the term bone broth my original thought was "what is this magical bone broth everyone is talking about" and then I learnt that really bone broth is just what broth is to our parents and grandparents. In the interest of making food go much further and truly being a whole food eater this is probably one of the most simple recipes I can offer you.
My recipe uses a slow cooker because I really like the "set it and forget it" function that it offers you can make this on the stove top or in an instant pot. The benefit to not using the stove top method is you don't need to worry about things overheating or causing destruction within your house, bone broth takes at least 24 hours in a slow cooker or on the stove top so you can see how a "set it and forget it" system would work best.
Chicken Bone Broth:
1 chicken carcass
4-5 garlic cloves
1 bunch thyme
1 bunch rosemary
1 tbsp coconut vinegar
*Pro-Tip: DO NOT over fill. Liquid expands when frozen, so if you fill a container all the way to the top it will overflow, or worse if you are using a mason jar it will break your jar, meaning you will have to toss all your broth because there is now the potential that you could swallow glass. For this reason I typically use tuperware because it is much more forgiving and even if I accidentally over fill the container won't crack.
