I made this last night, it was wonderful.

However, I made it a little bit differently.

I did NOT butter pan. I used a glass baking dish, the chicken (with mayo mixture coating) created more than enough juice, etc. to prevent stikcing or whatever the butter was meant for.

Also, in cheese and mayo mixture, I added parsely flakes, black peper, onion powder and garlic powder.

On a personal cooking note, I cooked at 400 degrees for 40 minutes. I am a freak about my chicken. I put on bottom rack in oven to prevent excessive browning on chicken.

Lastly, before putting in oven, I sprinkled with more parsely and some red pepper flakes. This make it look pretty (like the paprika would) and gave it another spice kick!
