Making your own tortilla strips to top your Instant Pot Chicken Tortilla Soup with is easy. Check out my 4 Ingredient Corn Tortilla recipe to make while your pressure cooker makes the delicious soup. When the tortillas are ready, cut into strips using a sharp knife and add to your Instant Pot Chicken Tortilla Soup when it’s ready to serve. If you want you can spray the tortilla strips with some olive oil, and crips them up in and Air Fryer or or on a baking sheet in the oven, before topping the soup. But please feel free to also grab some store bought tortilla if you prefer.
