Combine all ingredients (except optional toppings) in the instant pot or slow cooker.
Option 1: Use the manual button on the instant pot to cook for 12-15 minutes depending on how thick your chicken breasts are. I usually let the pressure release naturally but if you’re in a hurry you can do manual release. If the chicken doesn’t shred easily, cook a few minutes more.
Option 2: Cook in the slow cooker for about 6 hours on low or until the chicken shreds easily.
Add toppings and serve!
