I have had several variations of chicken casserole but this one beats the band! I just experimented until it was what my family liked. You will see how it differs and how rich and creamy it is by adding just a few more ingredients. Rice makes it go farther. Makes enough to feed 10 people with leftovers! You can add water chestnuts or slivered almonds to add crunch. Cooking time does not include time to boil boneless chicken breasts. Looks delish!!! No calories skimped on here.
