Add chicken parts + vegetables to a large stockpot. Ok, I’m going to get a little specific on you if you want. If you add the chicken first and let that come to a boil and then simmer it’s easier to skim the scum. After about 45 minutes of skimming then add your vegetables and herbs and finish. But it really doesn’t matter – you do you.
Fill with cold water until ingredients are covered by 1–2 inches.
Bring to a bare simmer over medium heat.
Gentle is key—rolling boiling = cloudy stock. To be specific – bring to a boil and then reduce to a simmer. Seeing the first bubbles indicates you’ve reach the right heat, reducing to simmer so you only see slight bubbles keeps it at the right heat and eliminates the cloudiness.
Simmer 3–4 hours.
For an ultra-rich version, go 5–6. I’m going to be honest, I never go that long with chicken stock. I’m convinced after 3 hours I’ve reached max flavor but you won’t know until you try it. When it tastes good to you – you’re done.
Skim occasionally to remove foam. No seriously, and see my note above about skimming. Skim that scum off your precious golden liquid. And do it frequently. You’ll notice with the pressure cooker method there is no skimming – that’s the shortcut. Stovetop is going old school your grandmas version and it generates scum that you need to get outta there. But this step does produce a better stock.
Strain, cool quickly, refrigerate.
