Turning leftover chicken bones into homemade bone broth in the slow cooker is my go-to method for transforming scraps into something cozy and deeply nourishing. This slow simmer draws out every bit of goodness from the bones, leaving you with flavorful broth perfect for sipping or as a base for soups and stews.
What Makes It Special
- Uses just three ingredients and water so it is budget friendly
- The slow cooker does all the work
- Rich in protein and collagen
- Can be made in large batches and stored for later
Making this broth filled my kitchen with the best comforting smell on a chilly day. The first time I made it I was amazed by how silky the texture turned out after a full day of gently simmering.
What You’ll Need
- Chicken bones from a roasted chicken: You get the best flavor and body so save those carcasses from family dinners
- Cold water: Use enough to fully cover the bones but leave room in the slow cooker for bubbling
- Apple cider vinegar: Helps draw out nutrients and minerals from the bones
- Sea salt or kosher salt (Optional): Add after cooking to control the seasoning
When picking bones choose ones with some meat and cartilage still attached these add wonderful depth. For vinegar choose raw unfiltered for more minerals.
Let’s Cook This Together
- Prep the Bones:
- Place chicken bones straight into your slow cooker Try to use bones from a roasted chicken for an even richer flavor
- Fill With Water:
- Pour in enough cold water to completely cover the bones but do not overfill because broth needs a bit of headspace
- Add Vinegar and Salt:
- Pour in the apple cider vinegar This helps pull beneficial minerals from the bones during cooking Add a pinch of salt if desired but you can season when serving instead
- Slow Cook:
- Set the slow cooker to low and let everything simmer for at least twelve hours and up to twenty four hours The longer the simmer the more flavor and gelatin you extract
- Cool and Strain:
- Turn off the slow cooker and let broth cool a bit so it is safe to handle Then strain the liquid through a fine mesh strainer or cheesecloth into a large bowl
- Chill and Store:
- Discard the bones and let the strained broth finish cooling fully Once completely cool store it in the refrigerator or freezer
