Rice can be added to the soup to not have so much broth. We prefer it to be broth-y so we can dip fresh tortillas into the soup. Butter the tortillas and dip them in the broth. This in turn makes the soup more filling.

Instant pot chicken fajita soup is great for summer and winter soups. We use a variety of bell peppers in this soup. Red, green, even yellow bell peppers are perfectly fine to use in this instant pot soup. Additionally, using white or yellow onion is also perfectly fine.

What size Instant Pot:

The instant pot we use here is a instant pot duo plus 9 in 1. It’s a 6 quart pot but if you want to make this recipe in a 8 quart pot just follow the same directions. If you want to make this instant pot meatball recipe in a 3 quart pot then cut the recipe in half but not the cook time.

Can I Use Frozen Chicken In The Instant Pot:

The short answer is Yes! Frozen chicken can be used in the instant pot. Usually when using frozen chicken in the instant pot add a little more time. In this recipe I use a frozen chicken breast. If your chicken is not frozen you do not need to adjust the cook time.

broth, onions, peppers. and chicken

For this chicken soup we used a packet of fajita seasoning. If you cannot find fajita seasoning locally then use about 1 tablespoon each of cumin, paprika, chili powder, and garlic. Then 1 teaspoon of cayenne pepper. It should give the soup just as good of a flavor as if you used an seasoning packet.

Lastly, after cooking be sure to pull the chicken breast back out of the pot and shred it down. Place the chicken back into the pot and give it a good stir. If you’d like more instant soup recipes check out a few more listed below.
