Preheat the oven to 400 F and line a baking sheet with parchment paper. Season your soup bones with salt and pepper and transfer to the oven. Bake for 15 minutes or until lightly browned. Remove from the oven.
Transfer the bones to the slow cooker along with the vegetable scraps, herbs, and apple cider vinegar. Cover with water (enough to cover the bones and vegetables)
Place the lid on the slow cooker and cook on low for 24 hours.
Using a fine mesh strainer, carefully strain the broth. Allow to cool before storing in the fridge or freezer, and using in soups, stews, pot roast, etc!
Notes
Freeze for 3-6 months. Allow the broth to fully cool before freezing in souper cubes before shrink wrapping in a vacuum sealer to avoid freezer burn.
Store in glass for 3-5 days. I love to use these glass jars to store my bone broth in the fridge.
