TIPS AND FAQS
If you want to make this soup a little more filling, add one cup of rice to your Instant Pot when you put in your chicken, water and stock. Make sure that your rice is completely covered with water.
This recipe is very flexible. You can add black beans, or top with fresh cilantro. It’s simple to turn this meal into anything that your family loves.
I used chicken breasts to make this soup but chicken thighs would also be delicious and even more tender in your soup.
Want to spice this soup up some? Add in a can of diced green chilies when you add your broth and water to the Instant Pot. It will increase the flavor and add some spice. For even more spiciness you can add some crushed red pepper flakes at the same time.
Chicken Fajita soup is easy to reheat. You can reheat your soup in the microwave or in a sauce pot on the stove on medium heat until it is warm. I find that the soup tastes better the second or third day. The flavors get stronger.
