Season the Chicken: In a medium bowl, place the chicken breasts and sprinkle with Italian seasoning, sea salt, and black pepper.
Toss thoroughly to ensure each breast is evenly coated.
Arrange in Instant Pot: Transfer the seasoned chicken breasts to the inner pot of your Instant Pot.
Pour the chicken broth around the sides of the chicken, not directly over the top, to keep the seasoning intact.
Pressure Cook: Secure and lock the lid, ensuring the steam release valve is set to the 'Sealing' position. Select 'Pressure Cook' (or 'Manual') and set the timer to 8 minutes on high pressure for 8 oz. (226.8 g) breasts. For larger breasts, add 1 minute for every additional 2 oz. (56.7 g)
Natural Release: Once the cooking cycle is complete, allow the pressure to release naturally for at least 10 minutes. This step is crucial for tender, juicy chicken.
Afterward, you can perform a quick release for any remaining pressure.
Shred and Serve: Carefully open the lid. The chicken will be incredibly tender. Use two forks to shred the chicken directly in the pot.
Stir the shredded chicken into the flavourful cooking liquid to reabsorb all the juices.
Serve immediately or store for later.
Don't Waste the Liquid: The leftover broth in the pot is pure liquid gold! Store your shredded chicken in it to keep it moist, or freeze it for a flavorful soup base.
