Cook your chicken breasts and shred them. I do this by putting them in the crock pot for 4-5 hours. I do not add any water or anything. When they are done drain the broth and let cool so that they are easy to shred.
Place the shredded chicken into your instant pot.
Cover with the cream cheese blocks, garlic, butter, Parmesan, Italian seasoning, and heavy cream.
Finish off with the broccoli and pour water over the top. You can also add the optional sun-dried tomatoes to the top.
Set your instant pot for 15 minutes and let it do its thing. I like to get mine ready in the morning and set the delay timer so we have hot and wonderful food ready at dinner time. After we eat I take the extra out and freeze it for another day!
This pot will make 2 9x13 pans of food! Enjoy!
