Trim any excess fat and skin off of chicken and place it in a pressure cooker or stock pot.
Give the celery, carrots and onions a rough chop and add to pot. Add all remaining ingredients.
Add water so it covers the ingredients by a couple inches. If using a pressure cooker, do not exceed the max fill line. In my pressure cooker, I add about 12 cups of water. In a stock pot, I generally add 12-16 cups.
Cook Broth
Pressure Cooker: Cook at high pressure for 45 minutes and then do a natural release.
Stove Top: Bring to a boil and reduce to a simmer. Simmer covered, stirring occasionally for 1-2 hours.
Strain mixture to remove solids. Cool broth to room temp and then store in portioned containers in the freezer for up to 3 months, or in the fridge for about 5 days. Quantity varies, but it will reduce in volume after simmering.
