- Spread half of the potatoes in bottom of prepared pan. Spread the cubed Smart Chicken breasts and/or thighs evenly on top. Season Smart Chicken with salt, pepper, and poultry seasoning. Layer with 1/2 of the bacon crumbles, 3/4 cup of cheddar or Mexican cheese, 1/2 (4 ounces) of the cubed cream cheese and 1/2 cup of green onion.
- Layer with the remaining potatoes, bacon, 3/4 cup cheddar or Mexican cheese, 1/2 (4 ounces) of cubed cream cheese and 1/2 cup green onion.
- Pour cream or half-and-half over casserole. Cover with aluminum foil and bake in the preheated oven for approximately one hour. In the last five minutes of baking, uncover and sprinkle with the remaining 1/2 cup cheddar cheese and continue bake for about five minutes more or until cheese is hot, bubbly and melted. Remove from the oven and let it rest about five minutes.
