Pour chicken broth into the Instant Pot. Add chicken breasts in a single layer. Sprinkle taco seasoning over the chicken breasts. Top with salsa.
Secure the lid and make sure the pressure valve is set to SEALING. Select the HIGH PRESSURE (or manual cook mode) and set the timer for 15 minutes.
When the timer is done, let the pressure naturally release for 10 minutes and then manually release the rest of the pressure.
Remove chicken breast and place them on a cutting board or plate. Shred the chicken with two forks.
Drain about ¼ cup of liquid from the Instant Pot into a measuring cup. I like to reserve this incase the tacos need a little additional liquid after mixing.
Put the shredded chicken breast back into the Instant Pot. Add lime juice and zest. Stir to combine. Serve on flour or corn tortillas.
Notes
Boneless, skinless chicken thighs may be used instead of chicken breasts.
If you use frozen chicken breasts, you don’t need to change the temperature or cook time. Your Instant Pot will just take longer to build up to pressure. You do need to make sure they are positioned in a single layer and not stuck together. The chicken will not cook.
Use jarred salsa for this recipe - it combines with the chicken broth to create a taco flavored tomato sauce for the taco meat. Save the fresh pico de gallo for serving. Make sure to place the salsa on top of the chicken breasts. If the salsa is on the bottom of the pot, it can cause the burn notice warning to go off.
Tested in a 6-quart Instant Pot.
