Instant Pot Chicken Stuffing Casserole has all the flavors of fall and that delicious stuffing we all love, packed with chicken and seasonings to make a hearty and delicious meal.
Heat the Instant Pot on Sauté Mode. When hot, add the butter. When melted, add the onion, mushroom, and celery and sauté for 3 minutes. Turn off sauté mode.
Add the seasonings, chicken broth, and chicken to the pot. Stir to incorporate.
Pour the stuffing mix on top and just lightly stir it in with a fork so it’s not dry, but not fully incorporated. If you stir it up, the stuffing will soak in too fast and might cause a burn notice.
Close the lid and set the vent to sealing (if necessary). Press the pressure cook or manual button and set the cook time to 5 minutes on high pressure.
When the time is up, manually release the pressure. Open the lid. Let sit for 5 minutes to thicken before serving.
