Pound out the chicken breasts so they are even in thickness. Place in the bottom of the pot (it’s OK if they overlap a bit.)
1.5-2 pounds boneless skinless chicken breasts
In a small bowl, mix the other 4 ingredients and then pour over the chicken.
1 pkt (1 oz.) onion soup mix, 1 cup Catalina dressing, 1/2 cup apricot preserves, ¼ cup chicken stock
Close and lock the lid, turning the steam release valve to closed. Press Steam (high pressure) and adjust the time down to 8 minutes. Pres Start/Stop.
When the cooking time has ended, allow a 10 minute NPR and then release any remaining pressure. Press Start/Stop. Open and remove the chicken breasts, setting them aside to rest.
If desired, dissolve 1 tbsp of corn starch in ¼ cup of cold water and add to the sauce to thicken. Use the saute or simmer setting to cook for a few minutes until desired thickness is achieved. Spoon over the chicken and serve.
