Place the lid on the pressure cooker and ensure the pressure regulator is set to "Sealing." Program the cooker to pressure cook for 25 minutes at high pressure. After cooking the soup, wait for about 15 minutes before quickly releasing the pressure. This helps prevent excessive steam and broth from spitting out of the valve. Be cautious when releasing the steam! Alternatively, you can allow the pressure to release naturally, but this will take some time.
Use tongs or a slotted spoon to remove the chicken from the pot and transfer it to a dish. Allow it to cool for about 15-20 minutes until it's easy to handle.
Add celery, carrots, and onion to the broth. Cover the pressure cooker with the lid and set the pressure regulator to "Sealing". Program the cooker to pressure cook for 5 minutes at high pressure. After cooking the soup, wait for about 10 minutes before quickly releasing the pressure.
While vegetables are cooking, boil and prepare noodles according to package directions. And shred the chicken. If you want a brothy soup, then only prepare 1/2 of a package of noodles. For a more hearty soup, prepare the entire package. Once you have released the pressure from the Instant Pot. Stir in the shredded chicken and the amount of noodles you desire. Ladle and serve up immediately.
You can also serve this soup with the noodles on the side and allow each person to add their own noodles. However you choose to serve it, everyone will love it.
