I wasn't expecting the polenta to be creamy, thought it be a set layer in the casserole. I tried to lighten it by eliminating the addition of butter and only adding 1/2 cup of Parmesan cheese in the polenta; not sure if that affected the consistency or not. The taste was okay, not sure I'd make it again, I'll see what leftovers are like.
I love this recipe and everyone that I have served it to has raved about it. It's quick and easy, especially if you use precooked chicken. I usually pan grill chicken tenders and dice them, but that's my preference. I have found that I like to add an extra 1/2 cup of corn meal to make the polenta a little thicker.
