Select “sauté” on Instant Pot and add oil. When it shows “hot” add carrots, onions and celery. Sauté with a wooden spoon for about 3 minutes.
Add chicken and garlic and continue sautéing until chicken is white, about 3-4 more minutes.
Press cancel. Add parsley, Italian seasoning, salt, pepper and stir. Add noodles, chicken broth and water. Stir gently and make sure everything is submerged. Secure lid, set vent to “sealing”, and pressure cook on high (“Manual” on some pots) for 5 minutes. It will take several minutes to come to pressure before cooking timer starts.
After cook time is complete, quick release the pressure, remove lid and serve.
