Place the whole chicken in a large pot.
Add the quartered onions, chopped carrots, and celery to the pot.
Smash the garlic cloves and add them to the pot.
Pour in enough water to cover the chicken and vegetables (about 10-12 cups).
Add the bay leaf and season with salt and pepper.
Bring the mixture to a boil over medium-high heat.
Once boiling, reduce the heat to low and let it simmer.
Skim off any foam that rises to the surface for a clearer broth.
Simmer for about 2 hours, or until the chicken is cooked through and tender.
Remove the chicken and vegetables, and strain the broth into a clean pot.
