Boil noodles.
Brown & dice chicken, if not already done. I used a big pan so I could mix up the whole casserole in it once the chicken was ready.
Combine butter, cooked chicken, soup, sour cream, salt, pepper and broth (or white wine, if using). Add cooked noodles. Stir together.
Pour into a greased 13x9 (or 2 8x8 or 9x9 pans). Sprinkle both cheeses on top.
If baking immediately, bake in a 300 degree oven for 45 minutes, covered with foil. Remove foil and bake for another 15 minutes.
If refrigerating for later, bake at 300 degrees for 55 minutes, covered with foil. Remove foil and bake for another 15 minutes.
If freezing, wrap before baking. To bake, defrost overnight or add another 30 minutes or so to bake at 300 for 1 hour, 20 minutes. Remove foil and bake for another 15 minutes.
Enjoy!
