Add chicken breasts, chicken broth, beans, salsa, chilies, onion, garlic, and seasonings to the Instant Pot insert.
Cover with Instant Pot lid, secure lid, and set Instant Pot to the "soup" setting for 15 minutes. After Instant Pot has finished cooking, manually release pressure.
Remove chicken from the pot and place on a cutting board or plate. If using corn, add it to the broth in the Instant Pot and secure the lid while you shred the chicken.
Shred (or chop) chicken and add back to the Instant Pot. Stir the soup to combine.
Serve with optional garnishes.
Notes
Nutrition calculated without garnishes.
Brown the chicken in the Instant Pot before pressure cooking for enhanced flavor.
If possible, make your own broth for a richer taste.
Taste the soup after cooking and add more spices or lime juice according to your preferences.
Add fresh cilantro, tortilla chips, cheese, sour cream, and avocado for added texture and flavor.
