Ingredients

4 medium carrots, cut into thirds 

5 pounds chicken bones, such as wings, necks, and backs, rinsed 

3 stalks celery, cut into thirds 

2 medium yellow onions, halved 

5 whole black peppercorns 

1 bay leaf 

Preparation

Make broth: Add chicken bones, large carrot pieces, celery, onions, peppercorns, and bay leaf to a large pot. Fill with enough cold water to cover ingredients by 2 inches and bring to a rapid simmer over medium-high. Reduce to a gentle simmer and cook 2 hours. Strain through a fine-mesh sieve and discard solids. Let broth cool, then refrigerate in an airtight container, 5 days (or freeze up to 6 months).
