  1. absolutely delicious! i used 2 bags of fresh spinach, sliced button and cremini mushrooms and followed the recipe. we really enjoyed this dish
  2. This is really good. I pretty much followed this except that I added more cheese (I grated a 10-oz block) and used 24-oz of frozen spinach, because there was no 20-oz pkg. Oh and I couldn't find light cream (I never can), so I used 1 c. heavy cream plus 1 c. half and half. WOW!!! That was incredible. Years ago when I moved to Alaska I made a dish only once, then lost the recipe. It involved cream, spinach and mushrooms and this is as close as I've found. It's outstanding! The only thing is that there was no way that would fit into a smaller dish. Perhaps it's the extra cheese and spinach, but mine fit perfectly in a 3-qt casserole. I also didn't put it in a pan of water. We had our Christmas dinner last night and there simply wasn't room, but it turned out fine. No burning! I even baked it for the same about of time. I will definitely be adding this to my recipe index.
  3. 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. :)
  4. 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!
  5. Loved by all! Used fresh spinach and chopped cremini mushrooms. Layered shredded swiss and shaved parmesan cheese throughout, followed remainder of the recipe. Topped with both cheeses as well as, panko bread crumbs. Delish!


  1. Yummy and easy. I made this with spray oil instead of butter, 1% milk instead of cream and cheddar instead of swiss. Delicious, even my one year old loved it.
  2. Very good but theres enough fat & sodium for an instant heart attack. I used lite margarine instead of butter, Mrs. dash for the salt, 2% milk for the cream & sprayed the dish with Pam, this cut the fat & sodium down 2/3%.
