Wonderfully tasting traditional Greek soup filled with the flavors of lemon, chicken and egg - using the Instant Pot speeds the whole process up!
Select the "saute" setting on the Instant Pot and let heat until the label reads "hot".
Add 1 tbsp olive oil then add the cubed chicken and saute until chicken is browned. Remove and set aside.
Add the other tbsp olive oil and add the onions and celery and saute for 2 minutes. Add the garlic and saute 1 minute longer.
Add the chicken back in and then add chicken broth, lemon zest, salt, pepper, and bay leaf. Press "cancel" on Instant Pot and turn off saute mode.
Cover and close the lid and make sure the vent on the lid is set to "sealing" position.
Select "manual" and set to 20 minutes.
Once time is up let the pressure come down naturally for 3 minutes and then carefully use the quick release method (QRM) to release any remaining pressure.
Whisk the egg in a medium bowl and then add the lemon juice and whisk until combined.
Slowly pour 1/2 cup of broth into the egg and lemon mixture, mixing continuously.
Pour the egg mixture into the soup while stirring constantly.
Top with chopped parsley for serving.
