Slowly whisk in the heavy cream until fully incorporated. Do not let the soup boil after adding the cream.
Stir in the shredded cheese until melted and the soup is creamy. Season with salt and pepper as needed.
Serve hot with your preferred toppings.
Notes
For the best creamy texture, add the heavy cream and cheese only after the pressure cooking cycle is complete and the soup is off the high heat.
Use store-bought rotisserie chicken to save time on cooking the chicken separately.
If you prefer a thicker soup, mix 1 tablespoon of cornstarch with 2 tablespoons of cold water and stir this slurry into the soup during the final simmering step.
