Begin by rinsing and draining the long grain white rice and black beans. Chop your toppings, including the fresh cilantro, green onion, and avocado. Set them aside for later.
Turn on your Instant Pot and select the ‘Sauté’ function. Add 1 cup of the low-sodium chicken broth to the pot. Place the boneless skinless chicken breasts into the broth. Sprinkle the taco seasoning evenly over the chicken, allowing it to absorb the flavors.
Once the chicken is slightly browned, add the rinsed and drained rice, the remaining 1/2 cup of chicken broth, black beans, corn, and salsa to the pot. Gently stir to combine all ingredients, ensuring the rice is submerged in the liquid.
Seal the Instant Pot lid and set the valve to the ‘Sealing’ position. Select the ‘Manual’ or ‘Pressure Cook’ setting and set the timer for 10 minutes. The pot will take a few minutes to come to pressure before the cooking time begins.
Once the cooking time is up, perform a quick release by carefully turning the valve to ‘Venting’. Once all the steam is released, open the lid and shred the chicken using two forks. Mix everything together in the pot, allowing the flavors to meld.
Scoop the chicken taco mixture into bowls. Top with shredded cheese, fresh cilantro, sliced avocado, green onion, and a dollop of sour cream if desired. Enjoy your delicious Instant Pot Chicken Taco Bowls!
