In Instant Pot, place chicken, onion, carrots, bay leaves, peppercorns and chicken broth.
Close the lid, set pressure vent to Sealing and press Pressure Cook on High or Manual for: whole chicken and bone-in pieces - 30 minutes, chicken breasts - 10 minutes.
After, wait for 10 minutes and do Quick Release by turning pressure valve to Venting position, which takes 3-4 minutes.
Open the lid and using a mesh strainer discard any foam, onion, bay leaves and peppercorns.
At this point chicken is so cooked, you can easily break it into pieces with a long utensil right inside the pot, remove bones. If using chicken breasts, remove on a plate and shred with 2 forks.
Add oregano, garlic powder, salt, pepper and egg noodles. Stir, close the lid, turn on Keep Warm and let noodles “cook” for 10 minutes.
Open, add fresh parsley or dill and serve hot. That was easy dinner in one pot.

Notes
Store: Chicken soup will last in the fridge for a few days but keep in mind with each day noodles "swell up". Therefore, 2 days is pushing it for me. Reheat in microwave or stove top only amount you plan on eating.
Freeze: If you plan on freezing soup, do not add pasta. Either cook noodles separately and add to each bowl, or scoop out pasta before freezing.
If using whole chicken: I recommend using small whole chicken with fat trimmed and skin removed. Drumsticks, thighs or legs would be great too.
Whole onion: Keep onion whole and don’t trim off “the hairy end”. It will be easy to discard. Treat half of large onion the same way.
Don't go over 2/3 full: If your inner pot doesn’t have 2/3 full marking, it is very important to fill the pot only 2/3 full when pressure cooking.
