I used a 6-quart Instant Pot. If you use frozen chicken, increase the pressure cooking time by 50%, or a total of 15 minutes. The heavy whipping cream didn't curdle. You can certainly add the whipping cream after pressure cooking, if you like. If you don’t have an Instant Pot, you can make this Creamy Chicken Piccata on a stove top. Just brown the chicken on a skillet and following the same method above. Simmer on low heat until the chicken thighs are cooked through.
