Place the chicken breasts into the Instant Pot and sprinkle with salt, pepper, cumin, and chili powder. Add the minced garlic on top.
Pour in the chicken broth, ensuring the liquid covers at least the bottom of the pot to generate steam and pressure.
Close the lid securely and set the valve to sealing. Select high pressure and cook for 10 minutes.
Once the cooking cycle completes, carefully perform a quick release by turning the valve to vent, listening for the steam to escape.
Open the lid and transfer the cooked chicken breasts to a plate. Use tongs to shred the chicken into bite-sized pieces; it should be juicy and easily pull apart.
Return the shredded chicken to the Instant Pot and stir it into the flavorful juices. Let it sit for a minute so it absorbs the spices and stays moist.
Transfer the tender, flavorful shredded chicken to a serving bowl or directly use it as a filling for tacos, salads, or bowls. Enjoy the juicy texture and aromatic spices.
