Grease a 9 X 11 pan and pre-heat oven to 350 degrees.
Layer half of the ingredients as follows:
Season with salt, pepper, and garlic powder.
Repeat layering steps (EXCEPT CHEESE) with the second half of the ingredients.
Season again and then cover with heavy cream. Slice butter and layer over top of casserole and cover tightly with foil. Put into the oven for 1 hour.
Remove casserole from oven and remove foil. Sprinkle on 1 cup of cheese and return to the oven for another 5 minutes.
Remove and let sit for 5 minutes before serving. Enjoy!
**NOTES: I strongly suggest seasoning and grilling the chicken and paraboiling the potatoes beforehand and reducing the cook time. This way is okay, but the chicken is fairly bland and the potatoes were a little too hard. This recipe definitely has potential though.
