Instant Pot Settings: Set the Instant Pot on SAUTE function & keep it on HIGH heat setting.
Saute Aromatics: Add oil. When the oil becomes hot gently release the chopped onion and garlic and saute until the onion begins to become translucent. Than, add the chopped jalapenos (skip if you hate spicy food) and saute for about 30 seconds. Also, add salt to quicken the process.
Saute seasonings: Now, add all the dry seasonings like paprika, cumin powder, oregano, red pepper flakes & chili/cayenne powder (skip if you are heat intolerant) and saute for 30 seconds.
De-glaze the pot: Next, add the chicken stock and de-glaze the pot very well scraping the sides & the bottom of the pot with the help of a spatula. This is help loosen any stuck food particles and prevent the BURN error.
Pressure Cook: Now, add the Worcestershire sauce, the diced tomatoes with juice and the tomato paste and give everything a very good mix. Add the drained and rinsed black beans and corn and stir well. Now, transfer the boneless & skinless chicken breasts into the pot. Do not stir. CANCEL the SAUTE function. Pressure Cook: PRESSURE COOK on HIGH for just 6 minutes.
Quick Pressure Release: Once, the pressure cooking cycle is over the Instant Pot will begin to beep. Immediately perform a quick pressure release (QPR) by manually moving the valve from the sealing to the venting position. Open the lid carefully once the steam escapes & the floating pin drops.
Shred Chicken: Fish out the cooked chicken breasts onto a plate and shred the chicken with the help of a fork. Set it aside.
Add dairy: Now, turn off the Instant Pot and add the cream (at room temperature or slightly warmed up) into the pot. Mix well. Hit back the SAUTE function and set the heat to LOW. For thicker soup read NOTES below #4.
Add Shredded Chicken: Transfer back the shredded chicken into the pot. Give everything a good mix to fully incorporate the chicken into the soup. Bring the soup to a gentle simmer.
Garnish & Serve: Turn off the Instant Pot. Serve the Creamy Tortilla Soup and top it with the topping of your choice like chopped avocados, chopped cilantro, lime wedges, tortilla chips & cream (we did not add any). Dig in! Enjoy!
