Place shredded meat across bottom of pot, then sprinkle uncooked noodles on top with seasonings on top of that.
Pour in your broth. Close lid and steam valve and set to pressure high for 5 minutes. Allow pressure to naturally release for 2 minutes when done, then quick release.
Stir contents, sprinkle in cheese, stir so it melts.
Set pot to saute. Cut room temp. cream cheese into chunks and add into pot. Slowly stir so that melts too and makes casserole creamy.
When bubbling add cornstarch into small bowl and whisk in water until it is smooth. Add into pot and stir so it thickens, turn pot off now.
Allow to sit for at least 5 minutes to continue to thicken up before serving.
