Season the chicken with garlic powder, salt and pepper. I use a combination of skinless, boneless chicken breasts and chicken thighs (skin and bone-in).
Turn your Instant Pot to the saute setting. My recommendation is to see your manufacturer’s guide for detailed instructions on how to use your instant pot. Add the unsalted butter and cook until the butter has melted. Add the diced onion, carrots, and celery and saute for 3 minutes until the onion softens and becomes translucent.
Add the thyme, parsley, oregano, chicken bouillon and stir. Pour in the chicken broth. Add the chicken pieces and add 4 cups of water. Close the Instant Pot lid and turn the valve to the sealing position. Pressure cook on high pressure for 20 minutes.
When the cooking time ends, allow the Instant Pot to naturally release, or use the quick release if in a rush by turning the steam release valve to the venting position. Always protect your hand with an oven mitt or kitchen towel to prevent burns, as the steam is very hot.
Remove the chicken pieces from the soup and shred them with two forks. Set aside.
Add the noodles to the soup and set the Instant Pot to the saute setting again. Cook for another 6 minutes uncovered, or until the noodles are cooked.
Turn off the Instant Pot, and add the shredded chicken back to the Instant Pot. Taste for seasoning and adjust as necessary. Garnish with additional parsley, if preferred. Enjoy!
