Can I use fresh mushrooms and fresh spinach instead? Also, would cream cheese work in place of the mascarpone?
Thank you, Kathy
Hi Kathy, yes to all 3 substitutions, they should all work just fine! With the fresh spinach and mushrooms, I would definitely sauté them before mixing it into the mixing bowl with the other ingredients prior to baking. This will get all the water out so the casserole will hold together and won’t be watery. I hope that helps!
This looks good, however in the picture, the mushrooms that added to the chicken look to be canned. If I use fresh mushrooms, what adjustments do you suggest I make?
Hi Cindy,
I almost never used canned mushrooms, but I decided to in order to make this a really quick and easy casserole to put together. I can certainly understand wanting to use fresh instead, so I would sauté them before adding them to the mixture. This will get them to release most of their moisture that you can discard, and won’t make the casserole watery. I hope that helps!
It was delicious, we all loved it.
