Awesomeness!! I just made this for dinner tonight. I used frozen spinach ( squeezed to death so no moisture was remaining) lol, added garlic and about 6 more ounces of mushrooms, I mixed the spinach in with the mushroom sauce when done instead of layering. It all fit perfectly into my 1.5 qt casserole dish. Delicious mushroom flavor & my 4 year old loved it. We will be making this again. :)

My family, including my 16 y/o dd all thought this was really good. I used a 12 oz bag of spinach and about 1 3/4 cup of fat free half & half. I also added a cooked and diced chicken breast. I thought there was plenty of spinach, but should have cut back to 1 tsp of salt (and I'm a salt lover). I also used a mixture of mozzerella, parmesan and cheddar cheeses. The casserole did turn out very watery, but it was due to the water that cooked out of the spinach, not the sauce. I tried soaking up as much as I could with paper towels, but there was still quite a bit of liquid at the bottom of the casserole dish. I just drained it as I was serving and it taste really good. I will try this again using swis and adding it between the layers as someone suggested. Thanks for yummy dish. **UPDATE** Made for Christmas dinner, but this time used a 15 oz bag of frozen spinach, well squeezed, and about 1 2/3 cup of cream, then mixed the spinach with the mushroom mixture and it was wonderful! It wasn't watery at all and my DH brought me the empty dish saying "for future reference, this was the first thing to go". I again used a mixture of mozzerella, parm and cheddar. Everyone loved it and commented on it. Thank you again - I will definitely be making this regularly!
