For ease of prepping, pick out your meat at the store and have the butcher separate the meat from the bones for you while you shop. (You may need to call your butcher ahead of time for this and go during off-peak times)
Place the bones from the whole chicken, drumsticks, and thighs inside the Instant Pot strainer, including neck bones from the carcass.
Add the onion, celery, carrots, whole peppercorns, fresh herbs to the strainer.
Fill the Instant Pot below the fill line with water. Place the strainer inside the pot and check to make sure the water hasn't risen over the fill line. Add apple cider vinegar.
Do not add salt to your broth. You can add salt to your broth once you drink it or cook with it.
Make sure the Instant Pot lid is sealed. Flip the knob towards "sealing" to seal in the pressure.
Plug in the Instant Pot and press "pressure cook". Turn the time to 2 hours or 120 minutes. The instant pot should say "on" at this point. This means that the pot is heating up and pressurizing. This should take about 30 minutes. Once the instant pot is up to temperature, it will start timing the 2-hour pressure cooking, so you will know how long this will take.
Once the instant pot is done with the cooking process, the heat will turn off. At this point, you will need to release the pressure from the pot. However, I do NOT recommend releasing the pressure manually from the pressure knob. Instead, allow the pressure to release naturally, which takes 10-25 minutes, but will keep steam/broth from shooting all over your ceiling!
When the silver knob drops next to the knob, the pressure has released. Please watch the quick 2-minute video linked for this in the post to see exactly what I mean.
Remove the lid and remove the strainer with all of the ingredients. Pour the liquid broth into a large vessel and ladle or funnel the broth into mason jars. Place the lid on, but not too tight.
The broth will keep for about three days in the fridge, or up to one month in the freezer.
