Chicken Bone Broth

1 . Stage

Preheat the oven to 450 degrees F (230 degrees C). Line a baking sheet with aluminum foil.

2 . Stage

Place chicken bones onto the prepared baking sheet.

3 . Stage

Place baking sheet in the preheated oven and roast bones for 30 minutes.

4 . Stage

Gently transfer bones from the baking sheet into a large and heavy stockpot. Add onion and enough water to cover the bones by 2 inches. Add vinegar, salt, and pepper and bring to a boil over high heat. Reduce heat to medium-low and simmer, partially covered, leaving enough space for steam to escape, for 4 to 5 hours. Check occasionally for froth or foam that develops on top of the water, removing it with a large spoon.

5 . Stage

Remove from the heat and let cool. Strain broth through a fine mesh strainer into a clean pot. Let cool completely. Store in the refrigerator and use within 5 days or freeze until ready to use.
